documentation: Part 1 of 2 updates to integrating docs to Eclipse help.
Hi, the generation of eclipse help files has been merged from the timo branch to the master. Since the creation of the timo branch there have been some changes to the master branch (e.g. new documentation, renamed documentation). This patch set does some cleanup for the renamed documentation and adds eclipse help generation support to the new documentation. 01: Removes the 'the' from the document titles 02..04: Cleanup obsolete artifacts resulting from the merge 05..08: Add eclipse help generation for ref-manual 09..13: Add eclipse help generation for kernel-dev 14..18: Add eclipse help generation for profile-manual Best regards, Timo This patch set originally contained 18 patches. I (Scott Rifenbark) had to push these changes as two parts. This is the first part. It does not include creation of the three cusomization files.

16 The history for each package contains a text file that has
17 name-value pairs with information about the package.
18 For example, <code class="filename">buildhistory/packages/core2-poky-linux/busybox/busybox/latest</code>
19 contains the following:
20 </p>
21<pre class="literallayout">
22 PV = 1.19.3

31 FILELIST = /etc/busybox.links /etc/init.d/hwclock.sh /bin/busybox /bin/sh
32 </pre>
33<p>
34 Most of these name-value pairs corresponds to variables used
35 to produce the package.
36 The exceptions are <code class="filename">FILELIST</code>, which is the
37 actual list of files in the package, and
38 <code class="filename">PKGSIZE</code>, which is the total size of files
39 in the package in bytes.
40 </p>
41<p>
42 There is also a file corresponding to the recipe from which the

16 The first thing you need to do is set up the OpenEmbedded build environment by sourcing
17 the <a class="link" href="structure-core-script.html" title="5.1.10. oe-init-build-env">environment setup script</a> as follows:
18 </p>
19<pre class="literallayout">
20 $ source oe-init-build-env [build_dir]
21 </pre>
22<p>
23 </p>
24<p>
25 The <code class="filename">build_dir</code> is optional and specifies the directory the
26 OpenEmbedded build system uses for the build -
27 the <a class="link" href="../dev-manual/build-directory.html" target="_self">Build Directory</a>.
28 If you do not specify a Build Directory it defaults to <code class="filename">build</code>
29 in your current working directory.
30 A common practice is to use a different Build Directory for different targets.
31 For example, <code class="filename">~/build/x86</code> for a <code class="filename">qemux86</code>
32 target, and <code class="filename">~/build/arm</code> for a <code class="filename">qemuarm</code> target.
33 See <a class="link" href="structure-core-script.html" title="5.1.10. oe-init-build-env">oe-init-build-env</a>
34 for more information on this script.
35 </p>
36<p>
37 Once the build environment is set up, you can build a target using:
38 </p>
39<pre class="literallayout">
40 $ bitbake &lt;target&gt;
41 </pre>
42<p>
43 </p>
44<p>
45 The <code class="filename">target</code> is the name of the recipe you want to build.
46 Common targets are the images in <code class="filename">meta/recipes-core/images</code>,
47 <code class="filename">/meta/recipes-sato/images</code>, etc. all found in the
48 <a class="link" href="../dev-manual/source-directory.html" target="_self">Source Directory</a>.
49 Or, the target can be the name of a recipe for a specific piece of software such as
50 <span class="application">busybox</span>.
51 For more details about the images the OpenEmbedded build system supports, see the
52 "<a class="link" href="ref-images.html" title="Chapter 8. Images">Images</a>" chapter.

14<a name="checksums"></a>3.2.2. Checksums (Signatures)</h3></div></div></div>
15<p>
16 The shared state code uses a checksum, which is a unique signature of a task's
17 inputs, to determine if a task needs to be run again.
18 Because it is a change in a task's inputs that triggers a rerun, the process
19 needs to detect all the inputs to a given task.
20 For shell tasks, this turns out to be fairly easy because
21 the build process generates a "run" shell script for each task and
22 it is possible to create a checksum that gives you a good idea of when
23 the task's data changes.
24 </p>
25<p>
26 To complicate the problem, there are things that should not be included in
27 the checksum.
28 First, there is the actual specific build path of a given task -
29 the <code class="filename">WORKDIR</code>.
30 It does not matter if the working directory changes because it should not
31 affect the output for target packages.
32 Also, the build process has the objective of making native/cross packages relocatable.
33 The checksum therefore needs to exclude <code class="filename">WORKDIR</code>.
34 The simplistic approach for excluding the working directory is to set
35 <code class="filename">WORKDIR</code> to some fixed value and create the checksum
36 for the "run" script.
37 </p>
38<p>
39 Another problem results from the "run" scripts containing functions that
40 might or might not get called.
41 The incremental build solution contains code that figures out dependencies
42 between shell functions.
43 This code is used to prune the "run" scripts down to the minimum set,
44 thereby alleviating this problem and making the "run" scripts much more
45 readable as a bonus.
46 </p>
47<p>
48 So far we have solutions for shell scripts.
49 What about python tasks?
50 The same approach applies even though these tasks are more difficult.
51 The process needs to figure out what variables a python function accesses
52 and what functions it calls.
53 Again, the incremental build solution contains code that first figures out
54 the variable and function dependencies, and then creates a checksum for the data
55 used as the input to the task.
56 </p>
57<p>
58 Like the <code class="filename">WORKDIR</code> case, situations exist where dependencies
59 should be ignored.
60 For these cases, you can instruct the build process to ignore a dependency
61 by using a line like the following:
62 </p>
63<pre class="literallayout">
64 PACKAGE_ARCHS[vardepsexclude] = "MACHINE"
65 </pre>
66<p>
67 This example ensures that the <code class="filename">PACKAGE_ARCHS</code> variable does not
68 depend on the value of <code class="filename">MACHINE</code>, even if it does reference it.
69 </p>
70<p>
71 Equally, there are cases where we need to add dependencies BitBake is not able to find.
72 You can accomplish this by using a line like the following:
73 </p>
74<pre class="literallayout">
75 PACKAGE_ARCHS[vardeps] = "MACHINE"
76 </pre>
77<p>
78 This example explicitly adds the <code class="filename">MACHINE</code> variable as a
79 dependency for <code class="filename">PACKAGE_ARCHS</code>.
80 </p>
81<p>
82 Consider a case with inline python, for example, where BitBake is not
83 able to figure out dependencies.
84 When running in debug mode (i.e. using <code class="filename">-DDD</code>), BitBake
85 produces output when it discovers something for which it cannot figure out
86 dependencies.
87 The Yocto Project team has currently not managed to cover those dependencies
88 in detail and is aware of the need to fix this situation.
89 </p>
90<p>
91 Thus far, this section has limited discussion to the direct inputs into a task.
92 Information based on direct inputs is referred to as the "basehash" in the
93 code.
94 However, there is still the question of a task's indirect inputs - the
95 things that were already built and present in the Build Directory.
96 The checksum (or signature) for a particular task needs to add the hashes
97 of all the tasks on which the particular task depends.
98 Choosing which dependencies to add is a policy decision.
99 However, the effect is to generate a master checksum that combines the basehash
100 and the hashes of the task's dependencies.
101 </p>
102<p>
103 At the code level, there are a variety of ways both the basehash and the
104 dependent task hashes can be influenced.
105 Within the BitBake configuration file, we can give BitBake some extra information
106 to help it construct the basehash.
107 The following statements effectively result in a list of global variable
108 dependency excludes - variables never included in any checksum:
109 </p>
110<pre class="literallayout">
111 BB_HASHBASE_WHITELIST ?= "TMPDIR FILE PATH PWD BB_TASKHASH BBPATH"
112 BB_HASHBASE_WHITELIST += "DL_DIR SSTATE_DIR THISDIR FILESEXTRAPATHS"
113 BB_HASHBASE_WHITELIST += "FILE_DIRNAME HOME LOGNAME SHELL TERM USER"
114 BB_HASHBASE_WHITELIST += "FILESPATH USERNAME STAGING_DIR_HOST STAGING_DIR_TARGET"
115 </pre>
116<p>
117 The previous example actually excludes
118 <a class="link" href="ref-variables-glos.html#var-WORKDIR" title="WORKDIR"><code class="filename">WORKDIR</code></a>
119 since it is actually constructed as a path within
120 <a class="link" href="ref-variables-glos.html#var-TMPDIR" title="TMPDIR"><code class="filename">TMPDIR</code></a>, which is on
121 the whitelist.
122 </p>
123<p>
124 The rules for deciding which hashes of dependent tasks to include through
125 dependency chains are more complex and are generally accomplished with a
126 python function.
127 The code in <code class="filename">meta/lib/oe/sstatesig.py</code> shows two examples
128 of this and also illustrates how you can insert your own policy into the system
129 if so desired.
130 This file defines the two basic signature generators <code class="filename">OE-Core</code>
131 uses: "OEBasic" and "OEBasicHash".
132 By default, there is a dummy "noop" signature handler enabled in BitBake.
133 This means that behavior is unchanged from previous versions.
134 <code class="filename">OE-Core</code> uses the "OEBasic" signature handler by default
135 through this setting in the <code class="filename">bitbake.conf</code> file:
136 </p>
137<pre class="literallayout">
138 BB_SIGNATURE_HANDLER ?= "OEBasic"
139 </pre>
140<p>
141 The "OEBasicHash" <code class="filename">BB_SIGNATURE_HANDLER</code> is the same as the
142 "OEBasic" version but adds the task hash to the stamp files.
143 This results in any metadata change that changes the task hash, automatically
144 causing the task to be run again.
145 This removes the need to bump <a class="link" href="ref-variables-glos.html#var-PR" title="PR"><code class="filename">PR</code></a>
146 values and changes to metadata automatically ripple across the build.
147 Currently, this behavior is not the default behavior for <code class="filename">OE-Core</code>
148 but is the default in <code class="filename">poky</code>.
149 </p>
150<p>
151 It is also worth noting that the end result of these signature generators is to
152 make some dependency and hash information available to the build.
153 This information includes:
154 </p>
155<pre class="literallayout">
156 BB_BASEHASH_task-&lt;taskname&gt; - the base hashes for each task in the recipe
157 BB_BASEHASH_&lt;filename:taskname&gt; - the base hashes for each dependent task
158 BBHASHDEPS_&lt;filename:taskname&gt; - The task dependencies for each task
159 BB_TASKHASH - the hash of the currently running task
160 </pre>

16 Build history is disabled by default.
17 To enable it, add the following statements to the end of your
18 <code class="filename">conf/local.conf</code> file found in the
19 <a class="link" href="../dev-manual/build-directory.html" target="_self">Build Directory</a>:
20 </p>
21<pre class="literallayout">
22 INHERIT += "buildhistory"
23 BUILDHISTORY_COMMIT = "1"
24 </pre>
25<p>
26 Enabling build history as previously described
27 causes the build process to collect build
28 output information and commit it to a local
29 <a class="link" href="../dev-manual/git.html" target="_self">Git</a> repository.
30 </p>
31<div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;">
32<h3 class="title">Note</h3>
33 Enabling build history increases your build times slightly,
34 particularly for images, and increases the amount of disk
35 space used during the build.
36 </div>
37<p>
38 </p>
39<p>
40 You can disable build history by removing the previous statements
41 from your <code class="filename">conf/local.conf</code> file.
42 However, you should realize that enabling and disabling
43 build history in this manner can change the
44 <code class="filename">do_package</code> task checksums, which if you
45 are using the OEBasicHash signature generator (the default
46 for many current distro configurations including
47 <code class="filename">DISTRO = "poky"</code> and
48 <code class="filename">DISTRO = ""</code>) will result in the packaging
49 tasks being re-run during the subsequent build.
50 </p>
51<p>
52 To disable the build history functionality without causing the
53 packaging tasks to be re-run, add just this statement to your
54 <code class="filename">conf/local.conf</code> file:

15<p>
16 By default, the OpenEmbedded build system disables
17 components that have commercial or other special licensing
18 requirements.
19 Such requirements are defined on a
20 recipe-by-recipe basis through the <code class="filename">LICENSE_FLAGS</code> variable
21 definition in the affected recipe.
22 For instance, the
23 <code class="filename">$HOME/poky/meta/recipes-multimedia/gstreamer/gst-plugins-ugly</code>
24 recipe contains the following statement:
25 </p>
26<pre class="literallayout">
27 LICENSE_FLAGS = "commercial"
28 </pre>
29<p>
30 Here is a slightly more complicated example that contains both an
31 explicit recipe name and version (after variable expansion):
32 </p>
33<pre class="literallayout">
34 LICENSE_FLAGS = "license_${PN}_${PV}"
35 </pre>
36<p>
37 In order for a component restricted by a <code class="filename">LICENSE_FLAGS</code>
38 definition to be enabled and included in an image, it
39 needs to have a matching entry in the global
40 <code class="filename">LICENSE_FLAGS_WHITELIST</code> variable, which is a variable
41 typically defined in your <code class="filename">local.conf</code> file.
42 For example, to enable
43 the <code class="filename">$HOME/poky/meta/recipes-multimedia/gstreamer/gst-plugins-ugly</code>
44 package, you could add either the string
45 "commercial_gst-plugins-ugly" or the more general string
46 "commercial" to <code class="filename">LICENSE_FLAGS_WHITELIST</code>.
47 See the
48 "<a class="link" href="license-flag-matching.html" title="3.4.2.1. License Flag Matching">License Flag Matching</a>" section
49 for a full explanation of how <code class="filename">LICENSE_FLAGS</code> matching works.
50 Here is the example:
51 </p>
52<pre class="literallayout">
53 LICENSE_FLAGS_WHITELIST = "commercial_gst-plugins-ugly"
54 </pre>
55<p>
56 Likewise, to additionally enable the package built from the recipe containing
57 <code class="filename">LICENSE_FLAGS = "license_${PN}_${PV}"</code>, and assuming
58 that the actual recipe name was <code class="filename">emgd_1.10.bb</code>,
59 the following string would enable that package as well as
60 the original <code class="filename">gst-plugins-ugly</code> package:
61 </p>
62<pre class="literallayout">
63 LICENSE_FLAGS_WHITELIST = "commercial_gst-plugins-ugly license_emgd_1.10"
64 </pre>
65<p>
66 As a convenience, you do not need to specify the complete license string
67 in the whitelist for every package.
68 you can use an abbreviated form, which consists
69 of just the first portion or portions of the license string before
70 the initial underscore character or characters.
71 A partial string will match
72 any license that contains the given string as the first
73 portion of its license.
74 For example, the following
75 whitelist string will also match both of the packages
76 previously mentioned as well as any other packages that have
77 licenses starting with "commercial" or "license".
78 </p>
79<pre class="literallayout">
80 LICENSE_FLAGS_WHITELIST = "commercial license"

16 You can examine build history output from the command line or
17 from a web interface.
18 </p>
19<p>
20 To see any changes that have occurred (assuming you have
21 <code class="filename">BUILDHISTORY_COMMIT = "1"</code>), you can simply
22 use any Git command that allows you to view the history of
23 a repository.
24 Here is one method:
25 </p>
26<pre class="literallayout">
27 $ git log -p
28 </pre>
29<p>
30 You need to realize, however, that this method does show
31 changes that are not significant (e.g. a package's size
32 changing by a few bytes).
33 </p>
34<p>
35 A command-line tool called <code class="filename">buildhistory-diff</code>
36 does exist though that queries the Git repository and prints just
37 the differences that might be significant in human-readable form.
38 Here is an example:
39 </p>
40<pre class="literallayout">

135 The term "Poky" refers to the specific reference build system that
136 the Yocto Project provides.
137 Poky is based on <a class="link" href="../dev-manual/oe-core.html" target="_self">OE-Core</a>
138 and BitBake.
139 Thus, the generic term used here for the build system is
140 the "OpenEmbedded build system."
141 Development in the Yocto Project using Poky is closely tied to OpenEmbedded, with
142 changes always being merged to OE-Core or BitBake first before being pulled back
143 into Poky.
144 This practice benefits both projects immediately.
145 For a fuller description of the term "Poky", see the
146 <a class="link" href="../dev-manual/poky.html" target="_self">poky</a> term in the Yocto Project
147 Development Manual.

163 You can use a stand-alone tarball to provide Python 2.6.
164 You can find pre-built 32 and 64-bit versions of Python 2.6 at the following locations:

170<p>
171 </p>
172<p>
173 These tarballs are self-contained with all required libraries and should work
174 on most Linux systems.
175 To use the tarballs extract them into the root
176 directory and run the appropriate command:
177 </p>
178<pre class="literallayout">
179 $ export PATH=/opt/poky/sysroots/i586-pokysdk-linux/usr/bin/:$PATH

181 </pre>
182<p>

185 Once you run the command, BitBake uses Python 2.6.

359 To get the Yocto Project working under RHEL/CentOS 5.1 you need to first
360 install some required packages.
361 The standard CentOS packages needed are:
362 </p>
363<div class="itemizedlist"><ul class="itemizedlist" type="disc">
364<li class="listitem"><p>"Development tools" (selected during installation)</p></li>
365<li class="listitem"><p><code class="filename">texi2html</code></p></li>
366<li class="listitem"><p><code class="filename">compat-gcc-34</code></p></li>
367</ul></div>
368<p>
369 On top of these, you need the following external packages:
370 </p>
371<div class="itemizedlist"><ul class="itemizedlist" type="disc">
372<li class="listitem"><p><code class="filename">python-sqlite2</code> from
373 <a class="ulink" href="http://dag.wieers.com/rpm/packages/python-sqlite2/" target="_self">DAG repository</a>
374 </p></li>
375<li class="listitem"><p><code class="filename">help2man</code> from
376 <a class="ulink" href="http://centos.karan.org/el4/extras/stable/x86_64/RPMS/repodata/repoview/help2man-0-1.33.1-2.html" target="_self">Karan repository</a></p></li>
377</ul></div>
378<p>
379 </p>
380<p>
381 Once these packages are installed, the OpenEmbedded build system will be able
382 to build standard images.
383 However, there might be a problem with the QEMU emulator segfaulting.
384 You can either disable the generation of binary locales by setting
385 <code class="filename"><a class="link" href="ref-variables-glos.html#var-ENABLE_BINARY_LOCALE_GENERATION" title="ENABLE_BINARY_LOCALE_GENERATION">ENABLE_BINARY_LOCALE_GENERATION</a>
386 </code> to "0" or by removing the <code class="filename">linux-2.6-execshield.patch</code>
387 from the kernel and rebuilding it since that is the patch that causes the problems with QEMU.

403 Nothing is wrong.
404 The OpenEmbedded build system checks any configured source mirrors before downloading
405 from the upstream sources.
406 The build system does this searching for both source archives and
407 pre-checked out versions of SCM managed software.
408 These checks help in large installations because it can reduce load on the SCM servers
409 themselves.
410 The address above is one of the default mirrors configured into the
411 build system.
412 Consequently, if an upstream source disappears, the team
413 can place sources there so builds continue to work.

492 If the same build is failing in totally different and random ways,
493 the most likely explanation is that either the hardware you're running the
494 build on has some problem, or, if you are running the build under virtualisation,
495 the virtualisation probably has bugs.
496 The OpenEmbedded build system processes a massive amount of data causing lots of network, disk and
497 CPU activity and is sensitive to even single bit failures in any of these areas.
498 True random failures have always been traced back to hardware or virtualisation issues.

512 This is a difficult question and you need to consult your lawyer for the answer

514 It is worth bearing in mind that for GPL compliance there needs to be enough

556 The default interfaces file provided by the netbase recipe does not

627<td align="left" valign="top">
628<p>
629 The toolchain configuration is very flexible and customizable.
630 It is primarily controlled with the
631 <code class="filename"><a class="link" href="ref-variables-glos.html#var-TCMODE" title="TCMODE">TCMODE</a></code> variable.
632 This variable controls which <code class="filename">tcmode-*.inc</code> file to include
633 from the <code class="filename">meta/conf/distro/include</code> directory within the
634 <a class="link" href="../dev-manual/source-directory.html" target="_self">source directory</a>.
635 </p>
636<p>
637 The default value of <code class="filename">TCMODE</code> is "default"
638 (i.e. <code class="filename">tcmode-default.inc</code>).
639 However, other patterns are accepted.
640 In particular, "external-*" refers to external toolchains of which there are some
641 basic examples included in the OpenEmbedded Core (<code class="filename">meta</code>).
642 You can use your own custom toolchain definition in your own layer
643 (or as defined in the <code class="filename">local.conf</code> file) at the location
644 <code class="filename">conf/distro/include/tcmode-*.inc</code>.
645 </p>
646<p>
647 In addition to the toolchain configuration, you also need a corresponding toolchain recipe file.
648 This recipe file needs to package up any pre-built objects in the toolchain such as
649 <code class="filename">libgcc</code>, <code class="filename">libstdcc++</code>,
650 any locales, and <code class="filename">libc</code>.
651 An example is the <code class="filename">external-sourcery-toolchain.bb</code>, which is located
652 in <code class="filename">meta/recipes-core/meta/</code> within the source directory.

666<td align="left" valign="top"></td>
667<td align="left" valign="top">
668<p>
669 The way the build system obtains source code is highly configurable.
670 You can setup the build system to get source code in most environments if
671 HTTP transport is available.
672 </p>
673<p>
674 When the build system searches for source code, it first tries the local download directory.
675 If that location fails, Poky tries PREMIRRORS, the upstream source,
676 and then MIRRORS in that order.
677 </p>
678<p>
679 By default, the OpenEmbedded build system uses the Yocto Project source PREMIRRORS
680 for SCM-based sources,
681 upstreams for normal tarballs, and then falls back to a number of other mirrors
682 including the Yocto Project source mirror if those fail.
683 </p>
684<p>
685 As an example, you could add a specific server for Poky to attempt before any
686 others by adding something like the following to the <code class="filename">local.conf</code>
687 configuration file:
688 </p>
689<pre class="literallayout">
690 PREMIRRORS_prepend = "\
691 git://.*/.* http://www.yoctoproject.org/sources/ \n \
692 ftp://.*/.* http://www.yoctoproject.org/sources/ \n \
693 http://.*/.* http://www.yoctoproject.org/sources/ \n \
694 https://.*/.* http://www.yoctoproject.org/sources/ \n"
695 </pre>
696<p>
697 </p>
698<p>
699 These changes cause Poky to intercept Git, FTP, HTTP, and HTTPS
700 requests and direct them to the <code class="filename">http://</code> sources mirror.
701 You can use <code class="filename">file://</code> URLs to point to local directories
702 or network shares as well.
703 </p>
704<p>
705 Aside from the previous technique, these options also exist:
706 </p>
707<pre class="literallayout">
708 BB_NO_NETWORK = "1"
709 </pre>
710<p>
711 This statement tells BitBake to throw an error instead of trying to access the
712 Internet.
713 This technique is useful if you want to ensure code builds only from local sources.
714 </p>
715<p>
716 Here is another technique:
717 </p>
718<pre class="literallayout">
719 BB_FETCH_PREMIRRORONLY = "1"
720 </pre>
721<p>
722 This statement limits Poky to pulling source from the PREMIRRORS only.
723 Again, this technique is useful for reproducing builds.
724 </p>
725<p>
726 Here is another technique:
727 </p>
728<pre class="literallayout">
729 BB_GENERATE_MIRROR_TARBALLS = "1"
730 </pre>
731<p>
732 This statement tells Poky to generate mirror tarballs.
733 This technique is useful if you want to create a mirror server.
734 If not, however, the technique can simply waste time during the build.
735 </p>
736<p>
737 Finally, consider an example where you are behind an HTTP-only firewall.
738 You could make the following changes to the <code class="filename">local.conf</code>
739 configuration file as long as the PREMIRROR server is up to date:
740 </p>
741<pre class="literallayout">
742 PREMIRRORS_prepend = "\
743 ftp://.*/.* http://www.yoctoproject.org/sources/ \n \
744 http://.*/.* http://www.yoctoproject.org/sources/ \n \
745 https://.*/.* http://www.yoctoproject.org/sources/ \n"
746 BB_FETCH_PREMIRRORONLY = "1"
747 </pre>
748<p>
749 These changes would cause Poky to successfully fetch source over HTTP and
750 any network accesses to anything other than the PREMIRROR would fail.
751 </p>
752<p>
753 The build system also honors the standard shell environment variables
754 <code class="filename">http_proxy</code>, <code class="filename">ftp_proxy</code>,
755 <code class="filename">https_proxy</code>, and <code class="filename">all_proxy</code>
756 to redirect requests through proxy servers.

772 Yes - you can easily do this.
773 When you use BitBake to build an image, all the build output goes into the

775 setup file.
776 By default, this <a class="link" href="../dev-manual/build-directory.html" target="_self">build directory</a>

781 Within the build directory is the <code class="filename">tmp</code> directory.
782 To remove all the build output yet preserve any source code or downloaded files
783 from previous builds, simply remove the <code class="filename">tmp</code> directory.

16 This manual provides reference information for the current release of the Yocto Project.
17 The Yocto Project is an open-source collaboration project focused on embedded Linux
18 developers.
19 Amongst other things, the Yocto Project uses the OpenEmbedded build system, which
20 is based on the Poky project, to construct complete Linux images.
21 You can find complete introductory and getting started information on the Yocto Project
22 by reading the
23 <a class="link" href="../yocto-project-qs/index.html" target="_self">Yocto Project Quick Start</a>.
24 For task-based information using the Yocto Project, see the
25 <a class="link" href="../dev-manual/index.html" target="_self">Yocto Project Development Manual</a>.
26 You can also find lots of information on the Yocto Project on the
27 <a class="ulink" href="http://www.yoctoproject.org" target="_self">Yocto Project website</a>.

15<p>
16 The shared state code uses checksums and shared state
17 cache to avoid unnecessarily rebuilding tasks.
18 As with all schemes, this one has some drawbacks.
19 It is possible that you could make implicit changes that are not factored
20 into the checksum calculation, but do affect a task's output.
21 A good example is perhaps when a tool changes its output.
22 Let's say that the output of <code class="filename">rpmdeps</code> needed to change.
23 The result of the change should be that all the "package", "package_write_rpm",
24 and "package_deploy-rpm" shared state cache items would become invalid.
25 But, because this is a change that is external to the code and therefore implicit,
26 the associated shared state cache items do not become invalidated.
27 In this case, the build process would use the cached items rather than running the
28 task again.
29 Obviously, these types of implicit changes can cause problems.
30 </p>
31<p>
32 To avoid these problems during the build, you need to understand the effects of any
33 change you make.
34 Note that any changes you make directly to a function automatically are factored into
35 the checksum calculation and thus, will invalidate the associated area of sstate cache.
36 You need to be aware of any implicit changes that are not obvious changes to the
37 code and could affect the output of a given task.
38 Once you are aware of such a change, you can take steps to invalidate the cache
39 and force the task to run.
40 The step to take is as simple as changing a function's comments in the source code.
41 For example, to invalidate package shared state files, change the comment statements
42 of <code class="filename">do_package</code> or the comments of one of the functions it calls.
43 The change is purely cosmetic, but it causes the checksum to be recalculated and
44 forces the task to be run again.

15<p>
16 The definition of 'matching' in reference to a
17 recipe's <code class="filename">LICENSE_FLAGS</code> setting is simple.
18 However, some things exist that you should know about in order to
19 correctly and effectively use it.
20 </p>
21<p>
22 Before a flag
23 defined by a particular recipe is tested against the
24 contents of the <code class="filename">LICENSE_FLAGS_WHITELIST</code> variable, the
25 string <code class="filename">_${PN}</code> (with
26 <a class="link" href="ref-variables-glos.html#var-PN" title="PN"><code class="filename">PN</code></a> expanded of course) is
27 appended to the flag, thus automatically making each
28 <code class="filename">LICENSE_FLAGS</code> value recipe-specific.
29 That string is
30 then matched against the whitelist.
31 So if you specify <code class="filename">LICENSE_FLAGS = "commercial"</code> in recipe
32 "foo" for example, the string <code class="filename">"commercial_foo"</code>
33 would normally be what is specified in the whitelist in order for it to
34 match.
35 </p>
36<p>
37 You can broaden the match by
38 putting any "_"-separated beginning subset of a
39 <code class="filename">LICENSE_FLAGS</code> flag in the whitelist, which will also
40 match.
41 For example, simply specifying "commercial" in
42 the whitelist would match any expanded <code class="filename">LICENSE_FLAGS</code>
43 definition starting with "commercial" such as
44 "commercial_foo" and "commercial_bar", which are the
45 strings that would be automatically generated for
46 hypothetical "foo" and "bar" recipes assuming those
47 recipes had simply specified the following:
48 </p>
49<pre class="literallayout">
50 LICENSE_FLAGS = "commercial"
51 </pre>
52<p>
53 </p>
54<p>
55 Broadening the match allows for a range of specificity for the items
56 in the whitelist, from more general to perfectly
57 specific.
58 So you have the choice of exhaustively
59 enumerating each license flag in the whitelist to
60 allow only those specific recipes into the image, or
61 of using a more general string to pick up anything
62 matching just the first component or components of the specified
63 string.
64 </p>
65<p>
66 This scheme works even if the flag already
67 has <code class="filename">_${PN}</code> appended - the extra <code class="filename">_${PN}</code> is
68 redundant, but does not affect the outcome.
69 For example, a license flag of "commercial_1.2_foo" would
70 turn into "commercial_1.2_foo_foo" and would match
71 both the general "commercial" and the specific
72 "commercial_1.2_foo", as expected.
73 The flag would also match
74 "commercial_1.2_foo_foo" and "commercial_1.2", which
75 does not make much sense regarding use in the whitelist.
76 </p>
77<p>
78 For a versioned string, you could instead specify
79 "commercial_foo_1.2", which would turn into
80 "commercial_foo_1.2_foo".
81 And, as expected, this flag allows
82 you to pick up this package along with
83 anything else "commercial" when you specify "commercial"
84 in the whitelist.
85 Or, the flag allows you to pick up this package along with anything "commercial_foo"
86 regardless of version when you use "commercial_foo" in the whitelist.
87 Finally, you can be completely specific about the package and version and specify
88 "commercial_foo_1.2" package and version.
89 </p>

16 When creating recipes using Bash and inserting code that handles build
17 logs you have the same goals - informative with minimal console output.
18 The syntax you use for recipes written in Bash is similar to that of
19 recipes written in Python described in the previous section.
20 </p>
21<p>
22 Following is an example written in Bash.
23 The code logs the progress of the <code class="filename">do_my_function</code> function.

16 When creating recipes using Python and inserting code that handles build logs
17 keep in mind the goal is to have informative logs while keeping the console as
18 "silent" as possible.
19 Also, if you want status messages in the log use the "debug" loglevel.
20 </p>
21<p>
22 Following is an example written in Python.
23 The code handles logging for a function that determines the number of tasks
24 needed to be run:

15<p>
16 A build's quality can be influenced by many things.
17 For example, if you upgrade a recipe to use a new version of an upstream software
18 package or you experiment with some new configuration options, subtle changes
19 can occur that you might not detect until later.
20 Consider the case where your recipe is using a newer version of an upstream package.
21 In this case, a new version of a piece of software might introduce an optional
22 dependency on another library, which is auto-detected.
23 If that library has already been built when the software is building,
24 then the software will link to the built library and that library will be pulled
25 into your image along with the new software even if you did not want the
26 library.
27 </p>
28<p>
29 The <code class="filename">buildhistory</code> class exists to help you maintain
30 the quality of your build output.
31 You can use the class to highlight unexpected and possibly unwanted
32 changes in the build output.
33 When you enable build history it records information about the contents of
34 each package and image and then commits that information to a local Git
35 repository where you can examine the information.

15<p>
16 All Python functions must now use four spaces for indentation.
17 Previously, an inconsistent mix of spaces and tabs existed,
18 which made extending these functions using
19 <code class="filename">_append</code> or <code class="filename">_prepend</code>
20 complicated given that Python treats whitespace as
21 syntactically significant.
22 If you are defining or extending any Python functions (e.g.
23 <code class="filename">populate_packages</code>, <code class="filename">do_unpack</code>,
24 <code class="filename">do_patch</code> and so forth) in custom recipes
25 or classes, you need to ensure you are using consistent
26 four-space indentation.

16 The following recipes have been removed.
17 For most of them, it is unlikely that you would have any
18 references to them in your own metadata.
19 However, you should check your metadata against this list to be sure:
20 </p>

46 Largely unmaintained PIM application suite.
47 It has been moved to <code class="filename">meta-gnome</code>
48 in <code class="filename">meta-openembedded</code>.</p></li>
49</ul></div>
50<p>
51 In addition to the previously listed changes, the
52 <code class="filename">meta-demoapps</code> directory has also been removed
53 because the recipes in it were not being maintained and many
54 had become obsolete or broken.
55 Additionally, these recipes were not parsed in the default configuration.
56 Many of these recipes are already provided in an updated and
57 maintained form within OpenEmbedded community layers such as
58 <code class="filename">meta-oe</code> and <code class="filename">meta-gnome</code>.
59 For the remainder, you can now find them in the
60 <code class="filename">meta-extras</code> repository, which is in the
61 Yocto Project source repositories.

16 The shared state cache (sstate-cache) as pointed to by
17 <a class="link" href="ref-variables-glos.html#var-SSTATE_DIR" title="SSTATE_DIR"><code class="filename">SSTATE_DIR</code></a> by default
18 now has two-character subdirectories to prevent there being an issue with too
19 many files in the same directory.
20 Also, native sstate-cache packages will go into a subdirectory named using
21 the distro ID string.
22 If you copy the newly structured sstate-cache to a mirror location
23 (either local or remote) and then point to it in
24 <a class="link" href="ref-variables-glos.html#var-SSTATE_MIRRORS" title="SSTATE_MIRRORS"><code class="filename">SSTATE_MIRRORS</code></a>,
25 you need to append "PATH" to the end of the mirror URL so that
26 the path used by BitBake before the mirror substitution is
27 appended to the path used to access the mirror.
28 Here is an example:
29 </p>
30<pre class="literallayout">
31 SSTATE_MIRRORS = "file://.* http://someserver.tld/share/sstate/PATH"

16 "Task" recipes are now known as "Package groups" and have
17 been renamed from <code class="filename">task-*.bb</code> to
18 <code class="filename">packagegroup-*.bb</code>.
19 Existing references to the previous <code class="filename">task-*</code>
20 names should work in most cases as there is an automatic
21 upgrade path for most packages.
22 However, you should update references in your own recipes and
23 configurations as they could be removed in future releases.
24 You should also rename any custom <code class="filename">task-*</code>
25 recipes to <code class="filename">packagegroup-*</code>, and change
26 them to inherit <code class="filename">packagegroup</code> instead of
27 <code class="filename">task</code>, as well as taking the opportunity
28 to remove anything now handled by
29 <code class="filename">packagegroup.bbclass</code>, such as providing
30 <code class="filename">-dev</code> and <code class="filename">-dbg</code>
31 packages, setting
32 <a class="link" href="ref-variables-glos.html#var-LIC_FILES_CHKSUM" title="LIC_FILES_CHKSUM"><code class="filename">LIC_FILES_CHKSUM</code></a>,

16 When determining what parts of the system need to be built, BitBake
17 uses a per-task basis and does not use a per-recipe basis.
18 You might wonder why using a per-task basis is preferred over a per-recipe basis.
19 To help explain, consider having the IPK packaging backend enabled and then switching to DEB.
20 In this case, <code class="filename">do_install</code> and <code class="filename">do_package</code>
21 output are still valid.
22 However, with a per-recipe approach, the build would not include the
23 <code class="filename">.deb</code> files.
24 Consequently, you would have to invalidate the whole build and rerun it.
25 Rerunning everything is not the best situation.
26 Also in this case, the core must be "taught" much about specific tasks.
27 This methodology does not scale well and does not allow users to easily add new tasks
28 in layers or as external recipes without touching the packaged-staging core.

16 Best practices exist while writing recipes that both log build progress and
17 act on build conditions such as warnings and errors.
18 Both Python and Bash language bindings exist for the logging mechanism:

20<div class="itemizedlist"><ul class="itemizedlist" type="disc">
21<li class="listitem"><p><span class="emphasis"><em>Python:</em></span> For Python functions, BitBake

24 <code class="filename">bb.note</code>, <code class="filename">bb.plain</code>,
25 and <code class="filename">bb.debug</code>.</p></li>
26<li class="listitem"><p><span class="emphasis"><em>Bash:</em></span> For Bash functions, the same set

22Executes the specified task (default is 'build') for a given set of BitBake files.
23It expects that BBFILES is defined, which is a space separated list of files to
24be executed. BBFILES does support wildcards.
25Default BBFILES are the .bb files in the current directory.
26
27Options:
28 --version show program's version number and exit
29 -h, --help show this help message and exit
30 -b BUILDFILE, --buildfile=BUILDFILE
31 execute the task against this .bb file, rather than a
32 package from BBFILES. Does not handle any
33 dependencies.
34 -k, --continue continue as much as possible after an error. While the
35 target that failed, and those that depend on it,
36 cannot be remade, the other dependencies of these
37 targets can be processed all the same.
38 -a, --tryaltconfigs continue with builds by trying to use alternative
39 providers where possible.
40 -f, --force force run of specified cmd, regardless of stamp status
41 -c CMD, --cmd=CMD Specify task to execute. Note that this only executes
42 the specified task for the providee and the packages
43 it depends on, i.e. 'compile' does not implicitly call
44 stage for the dependencies (IOW: use only if you know
45 what you are doing). Depending on the base.bbclass a
46 listtasks tasks is defined and will show available
47 tasks
48 -r PREFILE, --read=PREFILE
49 read the specified file before bitbake.conf
50 -R POSTFILE, --postread=POSTFILE
51 read the specified file after bitbake.conf
52 -v, --verbose output more chit-chat to the terminal

56 -S, --dump-signatures
57 don't execute, just dump out the signature
58 construction information
59 -p, --parse-only quit after parsing the BB files (developers only)
60 -s, --show-versions show current and preferred versions of all packages
61 -e, --environment show the global or per-package environment (this is

63 -g, --graphviz emit the dependency trees of the specified packages in
64 the dot syntax
65 -I EXTRA_ASSUME_PROVIDED, --ignore-deps=EXTRA_ASSUME_PROVIDED
66 Assume these dependencies don't exist and are already
67 provided (equivalent to ASSUME_PROVIDED). Useful to
68 make dependency graphs more appealing

16 Each target BitBake builds consists of multiple tasks such as
17 <code class="filename">fetch</code>, <code class="filename">unpack</code>,
18 <code class="filename">patch</code>, <code class="filename">configure</code>,
19 and <code class="filename">compile</code>.
20 For best performance on multi-core systems, BitBake considers each task as an independent
21 entity with its own set of dependencies.
22 </p>
23<p>
24 Dependencies are defined through several variables.
25 You can find information about variables BitBake uses in the BitBake documentation,
26 which is found in the <code class="filename">bitbake/doc/manual</code> directory within the
27 <a class="link" href="../dev-manual/source-directory.html" target="_self">Source Directory</a>.
28 At a basic level, it is sufficient to know that BitBake uses the
29 <code class="filename"><a class="link" href="ref-variables-glos.html#var-DEPENDS" title="DEPENDS">DEPENDS</a></code> and
30 <code class="filename"><a class="link" href="ref-variables-glos.html#var-RDEPENDS" title="RDEPENDS">RDEPENDS</a></code> variables when
31 calculating dependencies.

15<p>
16 BitBake also contains a set of "fetcher" modules that allow
17 retrieval of source code from various types of sources.
18 For example, BitBake can get source code from a disk with the metadata, from websites,
19 from remote shell accounts or from Source Code Management (SCM) systems
20 like <code class="filename">cvs/subversion/git</code>.
21 </p>
22<p>
23 Fetchers are usually triggered by entries in
24 <code class="filename"><a class="link" href="ref-variables-glos.html#var-SRC_URI" title="SRC_URI">SRC_URI</a></code>.
25 You can find information about the options and formats of entries for specific
26 fetchers in the BitBake manual located in the
27 <code class="filename">bitbake/doc/manual</code> directory of the
28 <a class="link" href="../dev-manual/source-directory.html" target="_self">Source Directory</a>.
29 </p>
30<p>
31 One useful feature for certain Source Code Manager (SCM) fetchers is the ability to
32 "auto-update" when the upstream SCM changes version.
33 Since this ability requires certain functionality from the SCM, not all
34 systems support it.
35 Currently Subversion, Bazaar and to a limited extent, Git support the ability to "auto-update".
36 This feature works using the <code class="filename"><a class="link" href="ref-variables-glos.html#var-SRCREV" title="SRCREV">SRCREV</a></code>
37 variable.
38 See the
39 "<a class="link" href="../dev-manual/platdev-appdev-srcrev.html" target="_self">Using an External SCM</a>" section
40 in the Yocto Project Development Manual for more information.

15<p>
16 BitBake parses configuration files, classes, and <code class="filename">.bb</code> files.
17 </p>
18<p>
19 The first thing BitBake does is look for the <code class="filename">bitbake.conf</code> file.
20 This file resides in the
21 <a class="link" href="../dev-manual/source-directory.html" target="_self">Source Directory</a>
22 within the <code class="filename">meta/conf/</code> directory.
23 BitBake finds it by examining its
24 <a class="link" href="ref-variables-glos.html#var-BBPATH" title="BBPATH"><code class="filename">BBPATH</code></a> environment
25 variable and looking for the <code class="filename">meta/conf/</code>
26 directory.
27 </p>
28<p>
29 The <code class="filename">bitbake.conf</code> file lists other configuration
30 files to include from a <code class="filename">conf/</code>
31 directory below the directories listed in <code class="filename">BBPATH</code>.
32 In general, the most important configuration file from a user's perspective
33 is <code class="filename">local.conf</code>, which contains a user's customized
34 settings for the OpenEmbedded build environment.
35 Other notable configuration files are the distribution
36 configuration file (set by the
37 <code class="filename"><a class="link" href="ref-variables-glos.html#var-DISTRO" title="DISTRO">DISTRO</a></code> variable)
38 and the machine configuration file
39 (set by the
40 <code class="filename"><a class="link" href="ref-variables-glos.html#var-MACHINE" title="MACHINE">MACHINE</a></code> variable).
41 The <code class="filename">DISTRO</code> and <code class="filename">MACHINE</code> BitBake environment
42 variables are both usually set in
43 the <code class="filename">local.conf</code> file.
44 Valid distribution
45 configuration files are available in the <code class="filename">meta/conf/distro/</code> directory
46 and valid machine configuration
47 files in the <code class="filename">meta/conf/machine/</code> directory.
48 Within the <code class="filename">meta/conf/machine/include/</code>
49 directory are various <code class="filename">tune-*.inc</code> configuration files that provide common
50 "tuning" settings specific to and shared between particular architectures and machines.
51 </p>
52<p>
53 After the parsing of the configuration files, some standard classes are included.
54 The <code class="filename">base.bbclass</code> file is always included.
55 Other classes that are specified in the configuration using the
56 <code class="filename"><a class="link" href="ref-variables-glos.html#var-INHERIT" title="INHERIT">INHERIT</a></code>
57 variable are also included.
58 Class files are searched for in a <code class="filename">classes</code> subdirectory
59 under the paths in <code class="filename">BBPATH</code> in the same way as
60 configuration files.
61 </p>
62<p>
63 After classes are included, the variable
64 <code class="filename"><a class="link" href="ref-variables-glos.html#var-BBFILES" title="BBFILES">BBFILES</a></code>
65 is set, usually in
66 <code class="filename">local.conf</code>, and defines the list of places to search for
67 <code class="filename">.bb</code> files.
68 By default, the <code class="filename">BBFILES</code> variable specifies the
69 <code class="filename">meta/recipes-*/</code> directory within Poky.
70 Adding extra content to <code class="filename">BBFILES</code> is best achieved through the use of
71 BitBake layers as described in the
72 "<a class="link" href="../dev-manual/understanding-and-creating-layers.html" target="_self">Understanding and
73 Creating Layers</a>" section of the Yocto Project Development Manual.
74 </p>
75<p>
76 BitBake parses each <code class="filename">.bb</code> file in <code class="filename">BBFILES</code> and
77 stores the values of various variables.
78 In summary, for each <code class="filename">.bb</code>
79 file the configuration plus the base class of variables are set, followed
80 by the data in the <code class="filename">.bb</code> file
81 itself, followed by any inherit commands that
82 <code class="filename">.bb</code> file might contain.
83 </p>
84<p>
85 Because parsing <code class="filename">.bb</code> files is a time
86 consuming process, a cache is kept to speed up subsequent parsing.
87 This cache is invalid if the timestamp of the <code class="filename">.bb</code>
88 file itself changes, or if the timestamps of any of the include,
89 configuration or class files the <code class="filename">.bb</code>
90 file depends on changes.

16 Once all the <code class="filename">.bb</code> files have been
17 parsed, BitBake starts to build the target (<code class="filename">core-image-sato</code>
18 in the previous section's example) and looks for providers of that target.
19 Once a provider is selected, BitBake resolves all the dependencies for
20 the target.
21 In the case of <code class="filename">core-image-sato</code>, it would lead to
22 <code class="filename">packagegroup-core-x11-sato</code>,
23 which in turn leads to recipes like <code class="filename">matchbox-terminal</code>,
24 <code class="filename">pcmanfm</code> and <code class="filename">gthumb</code>.
25 These recipes in turn depend on <code class="filename">eglibc</code> and the toolchain.

28 Sometimes a target might have multiple providers.
29 A common example is "virtual/kernel", which is provided by each kernel package.
30 Each machine often selects the best kernel provider by using a line similar to the
31 following in the machine configuration file:
32 </p>
33<pre class="literallayout">
34 PREFERRED_PROVIDER_virtual/kernel = "linux-yocto"
35 </pre>
36<p>
37 The default <code class="filename"><a class="link" href="ref-variables-glos.html#var-PREFERRED_PROVIDER" title="PREFERRED_PROVIDER">PREFERRED_PROVIDER</a></code>
38 is the provider with the same name as the target.
39 </p>
40<p>
41 Understanding how providers are chosen is made complicated by the fact
42 that multiple versions might exist.
43 BitBake defaults to the highest version of a provider.
44 Version comparisons are made using the same method as Debian.
45 You can use the
46 <code class="filename"><a class="link" href="ref-variables-glos.html#var-PREFERRED_VERSION" title="PREFERRED_VERSION">PREFERRED_VERSION</a></code>
47 variable to specify a particular version (usually in the distro configuration).
48 You can influence the order by using the
49 <code class="filename"><a class="link" href="ref-variables-glos.html#var-DEFAULT_PREFERENCE" title="DEFAULT_PREFERENCE">DEFAULT_PREFERENCE</a></code>
50 variable.
51 By default, files have a preference of "0".
52 Setting the <code class="filename">DEFAULT_PREFERENCE</code> to "-1" makes the
53 package unlikely to be used unless it is explicitly referenced.
54 Setting the <code class="filename">DEFAULT_PREFERENCE</code> to "1" makes it likely the package is used.
55 <code class="filename">PREFERRED_VERSION</code> overrides any <code class="filename">DEFAULT_PREFERENCE</code> setting.
56 <code class="filename">DEFAULT_PREFERENCE</code> is often used to mark newer and more experimental package
57 versions until they have undergone sufficient testing to be considered stable.
58 </p>
59<p>
60 In summary, BitBake has created a list of providers, which is prioritized, for each target.

14<a name="ref-bitbake-runtask"></a>6.5. Running a Task</h2></div></div></div>
15<p>
16 Tasks can either be a shell task or a Python task.
17 For shell tasks, BitBake writes a shell script to
18 <code class="filename">${WORKDIR}/temp/run.do_taskname.pid</code> and then executes the script.
19 The generated shell script contains all the exported variables, and the shell functions
20 with all variables expanded.
21 Output from the shell script goes to the file <code class="filename">${WORKDIR}/temp/log.do_taskname.pid</code>.
22 Looking at the expanded shell functions in the run file and the output in the log files
23 is a useful debugging technique.
24 </p>
25<p>
26 For Python tasks, BitBake executes the task internally and logs information to the
27 controlling terminal.
28 Future versions of BitBake will write the functions to files similar to the way
29 shell tasks are handled.
30 Logging will be handled in way similar to shell tasks as well.
31 </p>
32<p>
33 Once all the tasks have been completed BitBake exits.
34 </p>
35<p>
36 When running a task, BitBake tightly controls the execution environment
37 of the build tasks to make sure unwanted contamination from the build machine
38 cannot influence the build.
39 Consequently, if you do want something to get passed into the build
40 task's environment, you must take a few steps:
41 </p>
42<div class="orderedlist"><ol class="orderedlist" type="1">
43<li class="listitem">
44<p>Tell BitBake to load what you want from the environment
45 into the data store.
46 You can do so through the <code class="filename">BB_ENV_EXTRAWHITE</code>
47 variable.
48 For example, assume you want to prevent the build system from
49 accessing your <code class="filename">$HOME/.ccache</code> directory.
50 The following command tells BitBake to load
51 <code class="filename">CCACHE_DIR</code> from the environment into the data
52 store:
53 </p>
54<pre class="literallayout">
55 export BB_ENV_EXTRAWHITE="$BB_ENV_EXTRAWHITE CCACHE_DIR"
56 </pre>
57</li>
58<li class="listitem">
59<p>Tell BitBake to export what you have loaded into the
60 environment store to the task environment of every running task.
61 Loading something from the environment into the data store
62 (previous step) only makes it available in the datastore.
63 To export it to the task environment of every running task,
64 use a command similar to the following in your
65 <code class="filename">local.conf</code> or distro configuration file:
66 </p>
67<pre class="literallayout">
68 export CCACHE_DIR
69 </pre>
70</li>
71</ol></div>
72<p>
73 </p>
74<div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;">
75<h3 class="title">Note</h3>
76 A side effect of the previous steps is that BitBake records the variable
77 as a dependency of the build process in things like the shared state
78 checksums.
79 If doing so results in unnecessary rebuilds of tasks, you can whitelist the
80 variable so that the shared state code ignores the dependency when it creates
81 checksums.
82 For information on this process, see the <code class="filename">BB_HASHBASE_WHITELIST</code>
83 example in the "<a class="link" href="checksums.html" title="3.2.2. Checksums (Signatures)">Checksums (Signatures)</a>" section.

15<p>
16 Based on the generated list of providers and the dependency information,
17 BitBake can now calculate exactly what tasks it needs to run and in what
18 order it needs to run them.
19 The build now starts with BitBake forking off threads up to the limit set in the
20 <code class="filename"><a class="link" href="ref-variables-glos.html#var-BB_NUMBER_THREADS" title="BB_NUMBER_THREADS">BB_NUMBER_THREADS</a></code> variable.
21 BitBake continues to fork threads as long as there are tasks ready to run,
22 those tasks have all their dependencies met, and the thread threshold has not been
23 exceeded.
24 </p>
25<p>
26 It is worth noting that you can greatly speed up the build time by properly setting
27 the <code class="filename">BB_NUMBER_THREADS</code> variable.
28 See the
29 "<a class="link" href="../yocto-project-qs/building-image.html" target="_self">Building an Image</a>"
30 section in the Yocto Project Quick Start for more information.
31 </p>
32<p>
33 As each task completes, a timestamp is written to the directory specified by the
34 <code class="filename"><a class="link" href="ref-variables-glos.html#var-STAMP" title="STAMP">STAMP</a></code> variable (usually
35 <code class="filename">build/tmp/stamps/*/</code>).
36 On subsequent runs, BitBake looks at the <code class="filename">/build/tmp/stamps</code>
37 directory and does not rerun
38 tasks that are already completed unless a timestamp is found to be invalid.
39 Currently, invalid timestamps are only considered on a per
40 <code class="filename">.bb</code> file basis.
41 So, for example, if the configure stamp has a timestamp greater than the
42 compile timestamp for a given target, then the compile task would rerun.
43 Running the compile task again, however, has no effect on other providers
44 that depend on that target.
45 This behavior could change or become configurable in future versions of BitBake.
46 </p>
47<div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;">
48<h3 class="title">Note</h3>
49 Some tasks are marked as "nostamp" tasks.
50 No timestamp file is created when these tasks are run.
51 Consequently, "nostamp" tasks are always rerun.

28 BitBake is a program written in Python that interprets the metadata used by the OpenEmbedded
29 build system.
30 At some point, developers wonder what actually happens when you enter:
31 </p>
32<pre class="literallayout">
33 $ bitbake core-image-sato
34 </pre>
35<p>
36 </p>
37<p>
38 This chapter provides an overview of what happens behind the scenes from BitBake's perspective.
39 </p>
40<div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;">
41<h3 class="title">Note</h3>
42 BitBake strives to be a generic "task" executor that is capable of handling complex dependency relationships.
43 As such, it has no real knowledge of what the tasks being executed actually do.
44 BitBake just considers a list of tasks with dependencies and handles metadata
45 that consists of variables in a certain format that get passed to the tasks.

17 Recipes for Python extensions are simple.
18 These recipes usually only need to point to the source's archive and then inherit
19 the proper <code class="filename">.bbclass</code> file.
20 Building is split into two methods dependling on which method the module authors used.
21 </p>
22<p>
23 Extensions that use an Autotools-based build system require Autotools and
24 <code class="filename">distutils</code>-based <code class="filename">.bbclasse</code> files in their recipes.
25 </p>
26<p>
27 Extensions that use <code class="filename">distutils</code>-based build systems require

15</h2></div></div></div>
16<p>
17 You can use this class to build software from source code that is external to the
18 OpenEmbedded build system.
19 In other words, your source code resides in an external tree outside of the Yocto Project.
20 Building software from an external source tree means that the normal fetch, unpack, and
21 patch process is not used.
22 </p>
23<p>
24 To use the class, you need to define the
25 <a class="link" href="ref-variables-glos.html#var-S" title="S"><code class="filename">S</code></a> variable to point to the directory that contains the source files.
26 You also need to have your recipe inherit the <code class="filename">externalsrc.bbclass</code> class.
27 </p>
28<p>
29 This class expects the source code to support recipe builds that use the
30 <a class="link" href="ref-variables-glos.html#var-B" title="B"><code class="filename">B</code></a> variable to point to the directory in
31 which the OpenEmbedded build system places the generated objects built from the recipes.
32 By default, the <code class="filename">B</code> directory is set to the following, which is separate from the
33 Source Directory (<code class="filename">S</code>):
34 </p>
35<pre class="literallayout">
36 ${WORKDIR}/${BPN}-{PV}/
37 </pre>
38<p>
39 See the glossary entries for the
40 <a class="link" href="ref-variables-glos.html#var-WORKDIR" title="WORKDIR"><code class="filename">WORKDIR</code></a>,
41 <a class="link" href="ref-variables-glos.html#var-BPN" title="BPN"><code class="filename">BPN</code></a>,
42 <a class="link" href="ref-variables-glos.html#var-PV" title="PV"><code class="filename">PV</code></a>,
43 <a class="link" href="ref-variables-glos.html#var-S" title="S"><code class="filename">S</code></a>, and
44 <a class="link" href="ref-variables-glos.html#var-B" title="B"><code class="filename">B</code></a> for more information.
45 </p>
46<p>
47 You can build object files in the external tree by setting the
48 <code class="filename">B</code> variable equal to <code class="filename">"${S}"</code>.
49 However, this practice does not work well if you use the source for more than one variant
50 (i.e., "natives" such as <code class="filename">quilt-native</code>,
51 or "crosses" such as <code class="filename">gcc-cross</code>).
52 So, be sure there are no "native", "cross", or "multilib" variants of the recipe.
53 </p>
54<p>
55 If you do want to build different variants of a recipe, you can use the
56 <a class="link" href="ref-variables-glos.html#var-BBCLASSEXTEND" title="BBCLASSEXTEND"><code class="filename">BBCLASSEXTEND</code></a> variable.
57 When you do, the <a class="link" href="ref-variables-glos.html#var-B" title="B"><code class="filename">B</code></a> variable must support the
58 recipe's ability to build variants in different working directories.
59 Most autotools-based recipes support separating these directories.
60 The OpenEmbedded build system defaults to using separate directories for <code class="filename">gcc</code>
61 and some kernel recipes.
62 Alternatively, you can make sure that separate recipes exist that each
63 use the <code class="filename">BBCLASSEXTEND</code> variable to build each variant.
64 The separate recipes can inherit a single target recipe.
65 </p>
66<p>

68 "<a class="link" href="../dev-manual/building-software-from-an-external-source.html" target="_self">Building

16<p>
17 This class adds a step to the package generation process that sanity checks the
18 packages generated by the OpenEmbedded build system.
19 A range of checks are performed that check the build's output
20 for common problems that show up during runtime.
21 Distribution policy usually dictates whether to include this class.
22 </p>
23<p>
24 You can configure the sanity checks so that specific test failures either raise a warning or
25 an error message.
26 Typically, failures for new tests generate a warning.
27 Subsequent failures for the same test would then generate an error message
28 once the metadata is in a known and good condition.
29 You use the <code class="filename">WARN_QA</code> variable to specify tests for which you
30 want to generate a warning message on failure.
31 You use the <code class="filename">ERROR_QA</code> variable to specify tests for which you
32 want to generate an error message on failure.
33 </p>
34<p>
35 The following list shows the tests you can list with the <code class="filename">WARN_QA</code>
36 and <code class="filename">ERROR_QA</code> variables:
37 </p>
38<div class="itemizedlist"><ul class="itemizedlist" type="disc">
39<li class="listitem"><p><span class="emphasis"><em><code class="filename">ldflags:</code></em></span>
40 Ensures that the binaries were linked with the
41 <code class="filename">LDFLAGS</code> options provided by the build system.
42 If this test fails, check that the <code class="filename">LDFLAGS</code> variable
43 is being passed to the linker command.</p></li>
44<li class="listitem"><p><span class="emphasis"><em><code class="filename">useless-rpaths:</code></em></span>
45 Checks for dynamic library load paths (rpaths) in the binaries that
46 by default on a standard system are searched by the linker (e.g.
47 <code class="filename">/lib</code> and <code class="filename">/usr/lib</code>).
48 While these paths will not cause any breakage, they do waste space and
49 are unnecessary.</p></li>
50<li class="listitem"><p><span class="emphasis"><em><code class="filename">rpaths:</code></em></span>
51 Checks for rpaths in the binaries that contain build system paths such
52 as <code class="filename">TMPDIR</code>.
53 If this test fails, bad <code class="filename">-rpath</code> options are being
54 passed to the linker commands and your binaries have potential security
55 issues.</p></li>
56<li class="listitem"><p><span class="emphasis"><em><code class="filename">dev-so:</code></em></span>
57 Checks that the <code class="filename">.so</code> symbolic links are in the
58 <code class="filename">-dev</code> package and not in any of the other packages.
59 In general, these symlinks are only useful for development purposes.
60 Thus, the <code class="filename">-dev</code> package is the correct location for
61 them.
62 Some very rare cases do exist for dynamically loaded modules where
63 these symlinks are needed instead in the main package.
64 </p></li>
65<li class="listitem"><p><span class="emphasis"><em><code class="filename">debug-files:</code></em></span>
66 Checks for <code class="filename">.debug</code> directories in anything but the
67 <code class="filename">-dbg</code> package.
68 The debug files should all be in the <code class="filename">-dbg</code> package.
69 Thus, anything packaged elsewhere is incorrect packaging.</p></li>
70<li class="listitem"><p><span class="emphasis"><em><code class="filename">arch:</code></em></span>
71 Checks the Executable and Linkable Format (ELF) type, bit size and endianness
72 of any binaries to ensure it matches the target architecture.
73 This test fails if any binaries don't match the type since there would be an
74 incompatibility.
75 Sometimes software, like bootloaders, might need to bypass this check.
76 </p></li>
77<li class="listitem"><p><span class="emphasis"><em><code class="filename">debug-deps:</code></em></span>
78 Checks that <code class="filename">-dbg</code> packages only depend on other
79 <code class="filename">-dbg</code> packages and not on any other types of packages,
80 which would cause a packaging bug.</p></li>
81<li class="listitem"><p><span class="emphasis"><em><code class="filename">dev-deps:</code></em></span>
82 Checks that <code class="filename">-dev</code> packages only depend on other
83 <code class="filename">-dev</code> packages and not on any other types of packages,
84 which would be a packaging bug.</p></li>
85<li class="listitem"><p><span class="emphasis"><em><code class="filename">pkgconfig:</code></em></span>
86 Checks <code class="filename">.pc</code> files for any
87 <code class="filename">TMPDIR/WORKDIR</code> paths.
88 Any <code class="filename">.pc</code> file containing these paths is incorrect
89 since <code class="filename">pkg-config</code> itself adds the correct sysroot prefix
90 when the files are accessed.</p></li>
91<li class="listitem"><p><span class="emphasis"><em><code class="filename">la:</code></em></span>
92 Checks <code class="filename">.la</code> files for any <code class="filename">TMPDIR</code>
93 paths.
94 Any <code class="filename">.la</code> file continaing these paths is incorrect since
95 <code class="filename">libtool</code> adds the correct sysroot prefix when using the
96 files automatically itself.</p></li>

16<p>
17 This class handles building Linux kernels.
18 The class contains code to build all kernel trees.
19 All needed headers are staged into the
20 <code class="filename"><a class="link" href="ref-variables-glos.html#var-STAGING_KERNEL_DIR" title="STAGING_KERNEL_DIR">STAGING_KERNEL_DIR</a></code>
21 directory to allow out-of-tree module builds using <code class="filename">module.bbclass</code>.
22 </p>
23<p>
24 This means that each built kernel module is packaged separately and inter-module
25 dependencies are created by parsing the <code class="filename">modinfo</code> output.
26 If all modules are required, then installing the <code class="filename">kernel-modules</code>
27 package installs all packages with modules and various other kernel packages
28 such as <code class="filename">kernel-vmlinux</code>.
29 </p>
30<p>
31 Various other classes are used by the kernel and module classes internally including
32 <code class="filename">kernel-arch.bbclass</code>, <code class="filename">module_strip.bbclass</code>,
33 <code class="filename">module-base.bbclass</code>, and <code class="filename">linux-kernel-base.bbclass</code>.

17 The packaging classes add support for generating packages from a build's
18 output.
19 The core generic functionality is in <code class="filename">package.bbclass</code>.
20 The code specific to particular package types is contained in various sub-classes such as
21 <code class="filename">package_deb.bbclass</code>, <code class="filename">package_ipk.bbclass</code>,
22 and <code class="filename">package_rpm.bbclass</code>.
23 Most users will want one or more of these classes.
24 </p>
25<p>
26 You can control the list of resulting package formats by using the
27 <code class="filename"><a class="link" href="ref-variables-glos.html#var-PACKAGE_CLASSES" title="PACKAGE_CLASSES">PACKAGE_CLASSES</a></code>
28 variable defined in the <code class="filename">local.conf</code> configuration file,
29 which is located in the <code class="filename">conf</code> folder of the
30 <a class="link" href="../dev-manual/source-directory.html" target="_self">Source Directory</a>.
31 When defining the variable, you can specify one or more package types.
32 Since images are generated from packages, a packaging class is
33 needed to enable image generation.
34 The first class listed in this variable is used for image generation.
35 </p>
36<p>
37 The package class you choose can affect build-time performance and has space
38 ramifications.
39 In general, building a package with RPM takes about thirty percent more time as
40 compared to using IPK to build the same or similar package.
41 This comparison takes into account a complete build of the package with all
42 dependencies previously built.
43 The reason for this discrepancy is because the RPM package manager creates and
44 processes more metadata than the IPK package manager.
45 Consequently, you might consider setting <code class="filename">PACKAGE_CLASSES</code>
46 to "package_ipk" if you are building smaller systems.
47 </p>
48<p>
49 Keep in mind, however, that RPM starts to provide more abilities than IPK due to
50 the fact that it processes more metadata.
51 For example, this information includes individual file types, file checksum generation
52 and evaluation on install, sparse file support, conflict detection and resolution
53 for multilib systems, ACID style upgrade, and repackaging abilities for rollbacks.
54 </p>
55<p>
56 Another consideration for packages built using the RPM package manager is space.
57 For smaller systems, the extra space used for the Berkley Database and the amount
58 of metadata can affect your ability to do on-device upgrades.
59 </p>

17 Several programs can fulfill the same or similar function and be installed with the same name.
18 For example, the <code class="filename">ar</code> command is available from the
19 <code class="filename">busybox</code>, <code class="filename">binutils</code> and
20 <code class="filename">elfutils</code> packages.
21 The <code class="filename">update-alternatives.bbclass</code> class handles renaming the
22 binaries so that multiple packages can be installed without conflicts.
23 The <code class="filename">ar</code> command still works regardless of which packages are installed
24 or subsequently removed.
25 The class renames the conflicting binary in each package and symlinks the highest
26 priority binary during installation or removal of packages.

42 Class files are used to abstract common functionality and share it amongst multiple
43 <code class="filename">.bb</code> files.
44 Any metadata usually found in a <code class="filename">.bb</code> file can also be placed in a class
45 file.
46 Class files are identified by the extension <code class="filename">.bbclass</code> and are usually placed
47 in a <code class="filename">classes/</code> directory beneath the
48 <code class="filename">meta*/</code> directory found in the
49 <a class="link" href="../dev-manual/source-directory.html" target="_self">Source Directory</a>.
50 Class files can also be pointed to by BUILDDIR (e.g. <code class="filename">build/</code>)in the same way as
51 <code class="filename">.conf</code> files in the <code class="filename">conf</code> directory.
52 Class files are searched for in <a class="link" href="ref-variables-glos.html#var-BBPATH" title="BBPATH"><code class="filename">BBPATH</code></a>
53 using the same method by which <code class="filename">.conf</code> files are searched.
54</p>
55<p>
56 In most cases inheriting the class is enough to enable its features, although
57 for some classes you might need to set variables or override some of the
58 default behaviour.

16 Sometimes it is necessary in the OpenEmbedded build system to extend
17 <a class="link" href="ref-variables-glos.html#var-MACHINE_FEATURES" title="MACHINE_FEATURES"><code class="filename">MACHINE_FEATURES</code></a>
18 or <a class="link" href="ref-variables-glos.html#var-DISTRO_FEATURES" title="DISTRO_FEATURES"><code class="filename">DISTRO_FEATURES</code></a>
19 to control functionality that was previously enabled and not able
20 to be disabled.
21 For these cases, we need to add an
22 additional feature item to appear in one of these variables,
23 but we do not want to force developers who have existing values
24 of the variables in their configuration to add the new feature
25 in order to retain the same overall level of functionality.
26 Thus, the OpenEmbedded build system has a mechanism to
27 automatically "backfill" these added features into existing
28 distro or machine configurations.
29 You can see the list of features for which this is done by
30 finding the
31 <a class="link" href="ref-variables-glos.html#var-DISTRO_FEATURES_BACKFILL" title="DISTRO_FEATURES_BACKFILL"><code class="filename">DISTRO_FEATURES_BACKFILL</code></a>
32 and <a class="link" href="ref-variables-glos.html#var-MACHINE_FEATURES_BACKFILL" title="MACHINE_FEATURES_BACKFILL"><code class="filename">MACHINE_FEATURES_BACKFILL</code></a>
33 variables in the <code class="filename">meta/conf/bitbake.conf</code> file.
34 </p>
35<p>
36 Because such features are backfilled by default into all
37 configurations as described in the previous paragraph, developers
38 who wish to disable the new features need to be able to selectively
39 prevent the backfilling from occurring.
40 They can do this by adding the undesired feature or features to the
41 <a class="link" href="ref-variables-glos.html#var-DISTRO_FEATURES_BACKFILL_CONSIDERED" title="DISTRO_FEATURES_BACKFILL_CONSIDERED"><code class="filename">DISTRO_FEATURES_BACKFILL_CONSIDERED</code></a>
42 or <a class="link" href="ref-variables-glos.html#var-MACHINE_FEATURES_BACKFILL_CONSIDERED" title="MACHINE_FEATURES_BACKFILL_CONSIDERED"><code class="filename">MACHINE_FEATURES_BACKFILL_CONSIDERED</code></a>
43 variables for distro features and machine features respectively.
44 </p>
45<p>
46 Here are two examples to help illustrate feature backfilling:
47 </p>
48<div class="itemizedlist"><ul class="itemizedlist" type="disc">
49<li class="listitem"><p><span class="emphasis"><em>The "pulseaudio" distro feature option</em></span>:
50 Previously, PulseAudio support was enabled within the Qt and
51 GStreamer frameworks.
52 Because of this, the feature is backfilled and thus
53 enabled for all distros through the
54 <code class="filename">DISTRO_FEATURES_BACKFILL</code>
55 variable in the <code class="filename">meta/conf/bitbake.conf</code> file.
56 However, your distro needs to disable the feature.
57 You can disable the feature without affecting
58 other existing distro configurations that need PulseAudio support
59 by adding "pulseaudio" to
60 <code class="filename">DISTRO_FEATURES_BACKFILL_CONSIDERED</code>
61 in your distro's <code class="filename">.conf</code> file.
62 Adding the feature to this variable when it also
63 exists in the <code class="filename">DISTRO_FEATURES_BACKFILL</code>
64 variable prevents the build system from adding the feature to
65 your configuration's <code class="filename">DISTRO_FEATURES</code>, effectively disabling
66 the feature for that particular distro.</p></li>
67<li class="listitem"><p><span class="emphasis"><em>The "rtc" machine feature option</em></span>:
68 Previously, real time clock (RTC) support was enabled for all
69 target devices.
70 Because of this, the feature is backfilled and thus enabled
71 for all machines through the <code class="filename">MACHINE_FEATURES_BACKFILL</code>
72 variable in the <code class="filename">meta/conf/bitbake.conf</code> file.
73 However, your target device does not have this capability.
74 You can disable RTC support for your device without
75 affecting other machines that need RTC support
76 by adding the feature to your machine's
77 <code class="filename">MACHINE_FEATURES_BACKFILL_CONSIDERED</code>
78 list in the machine's <code class="filename">.conf</code> file.
79 Adding the feature to this variable when it also
80 exists in the <code class="filename">MACHINE_FEATURES_BACKFILL</code>
81 variable prevents the build system from adding the feature to
82 your configuration's <code class="filename">MACHINE_FEATURES</code>, effectively
83 disabling RTC support for that particular machine.</p></li>

18 Features do not have a one-to-one correspondence to packages, and they can
19 go beyond simply controlling the installation of a package or packages.
20 Sometimes a feature can influence how certain recipes are built.
21 For example, a feature might determine whether a particular configure option

16 The items below are features you can use with
17 <a class="link" href="ref-variables-glos.html#var-MACHINE_FEATURES" title="MACHINE_FEATURES"><code class="filename">MACHINE_FEATURES</code></a>.
18 Features do not have a one-to-one correspondence to packages, and they can
19 go beyond simply controlling the installation of a package or packages.
20 Sometimes a feature can influence how certain recipes are built.
21 For example, a feature might determine whether a particular configure option
22 is specified within <code class="filename">do_configure</code> for a particular
23 recipe.

25 Features provide a mechanism for working out which packages
26 should be included in the generated images.
27 Distributions can select which features they want to support through the
28 <code class="filename"><a class="link" href="ref-variables-glos.html#var-DISTRO_FEATURES" title="DISTRO_FEATURES">DISTRO_FEATURES</a></code>
29 variable, which is set in the <code class="filename">poky.conf</code> distribution configuration file.
30 Machine features are set in the
31 <code class="filename"><a class="link" href="ref-variables-glos.html#var-MACHINE_FEATURES" title="MACHINE_FEATURES">MACHINE_FEATURES</a></code>
32 variable, which is set in the machine configuration file and
33 specifies the hardware features for a given machine.
34 </p>
35<p>
36 These two variables combine to work out which kernel modules,
37 utilities, and other packages to include.
38 A given distribution can support a selected subset of features so some machine features might not
39 be included if the distribution itself does not support them.
40 </p>
41<p>
42 One method you can use to determine which recipes are checking to see if a
43 particular feature is contained or not is to <code class="filename">grep</code> through
44 the metadata for the feature.
45 Here is an example that discovers the recipes whose build is potentially
46 changed based on a given feature:
47 </p>
48<pre class="literallayout">
49 $ cd $HOME/poky
50 $ git grep 'contains.*MACHINE_FEATURES.*&lt;feature&gt;'
51 </pre>
52<p>
53 </p>
54<p>
55 This chapter provides a reference of shipped machine and distro features
56 you can include as part of the image, a reference on image types you can
57 build, and a reference on feature backfilling.

16 The OpenEmbedded build process supports several types of images to satisfy different needs.
17 When you issue the <code class="filename">bitbake</code> command you provide a &#8220;top-level&#8221; recipe
18 that essentially begins the build for the type of image you want.
19 </p>
20<div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;">
21<h3 class="title">Note</h3>
22 Building an image without GNU General Public License Version 3 (GPLv3) components
23 is only supported for minimal and base images.
24 Furthermore, if you are going to build an image using non-GPLv3 components,
25 you must make the following changes in the <code class="filename">local.conf</code> file
26 before using the BitBake command to build the minimal or base image:
27 <pre class="literallayout">
28 1. Comment out the EXTRA_IMAGE_FEATURES line
29 2. Set INCOMPATIBLE_LICENSE = "GPLv3"
30 </pre>
31</div>
32<p>
33 From within the <code class="filename">poky</code> Git repository, use the following command to list
34 the supported images:
35 </p>
36<pre class="literallayout">
37 $ ls meta*/recipes*/images/*.bb
38 </pre>
39<p>
40 These recipes reside in the <code class="filename">meta/recipes-core/images</code>,
41 <code class="filename">meta/recipes-extended/images</code>,
42 <code class="filename">meta/recipes-graphics/images</code>, and
43 <code class="filename">meta/recipes-sato/images</code> directories
44 within the <a class="link" href="../dev-manual/source-directory.html" target="_self">source directory</a>.
45 Although the recipe names are somewhat explanatory, here is a list that describes them:

127 From the Yocto Project release 1.1 onwards, <code class="filename">-live</code> and
128 <code class="filename">-directdisk</code> images have been replaced by a "live"
129 option in <code class="filename">IMAGE_FSTYPES</code> that will work with any image to produce an
130 image file that can be
131 copied directly to a CD or USB device and run as is.
132 To build a live image, simply add
133 "live" to <code class="filename">IMAGE_FSTYPES</code> within the <code class="filename">local.conf</code>
134 file or wherever appropriate and then build the desired image as normal.

61 Specifies if an output package should still be produced if it is empty.
62 By default, BitBake does not produce empty packages.
63 This default behavior can cause issues when there is an
64 <a class="link" href="ref-variables-glos.html#var-RDEPENDS" title="RDEPENDS"><code class="filename">RDEPENDS</code></a> or
65 some other runtime hard-requirement on the existence of the package.
66 </p>
67<p>
68 Like all package-controlling variables, you must always use them in
69 conjunction with a package name override.
70 Here is an example:
71 </p>
72<pre class="literallayout">
73 ALLOW_EMPTY_${PN} = "1"

85<p>When <code class="filename"><a class="link" href="ref-variables-glos.html#var-SRCREV" title="SRCREV">SRCREV</a></code>
86 is set to the value of this variable, it specifies that the latest
87 source revision in the repository should be used. Here is an example:

104 The <a class="link" href="../dev-manual/build-directory.html" target="_self">Build Directory</a>.
105 The OpenEmbedded build system places generated objects into the Build Directory
106 during a recipe's build process.
107 By default, this directory is the same as the <a class="link" href="ref-variables-glos.html#var-S" title="S"><code class="filename">S</code></a>
108 directory:
109 </p>
110<pre class="literallayout">
111 B = ${WORKDIR}/${BPN}-{PV}/
112 </pre>
113<p>
114 You can separate the (<code class="filename">S</code>) directory and the directory pointed to
115 by the <code class="filename">B</code> variable.
116 Most autotools-based recipes support separating these directories.
117 The build system defaults to using separate directories for <code class="filename">gcc</code>
118 and some kernel recipes.

124 A list of packages not to install despite being recommended by a recipe.
125 Support for this variable exists only when using the
126 <code class="filename">ipk</code> packaging backend.
127 </p></dd>
128<dt>
129<a name="var-BB_DISKMON_DIRS"></a>BB_DISKMON_DIRS</dt>
130<dd>
131<p>
132 Monitors disk space and available inodes during the build
133 and allows you to control the build based on these
134 parameters.
135 </p>
136<p>
137 Disk space monitoring is disabled by default.
138 To enable monitoring, add the <code class="filename">BB_DISKMON_DIRS</code>
139 variable to your <code class="filename">conf/local.conf</code> file found in the
140 <a class="link" href="../dev-manual/build-directory.html" target="_self">Build Directory</a>.
141 Use the following form:
142 </p>
143<pre class="literallayout">
144 BB_DISKMON_DIRS = "&lt;action&gt;,&lt;dir&gt;,&lt;threshold&gt; [...]"
145
146 where:
147
148 &lt;action&gt; is:
149 ABORT: Immediately abort the build when
150 a threshold is broken.
151 STOPTASKS: Stop the build after the currently
152 executing tasks have finished when
153 a threshold is broken.
154 WARN: Issue a warning but continue the
155 build when a threshold is broken.
156 Subsequent warnings are issued as
157 defined by the
158 <a class="link" href="ref-variables-glos.html#var-BB_DISKMON_WARNINTERVAL" title="BB_DISKMON_WARNINTERVAL">BB_DISKMON_WARNINTERVAL</a> variable,
159 which must be defined in the
160 conf/local.conf file.
161
162 &lt;dir&gt; is:
163 Any directory you choose. You can specify one or
164 more directories to monitor by separating the
165 groupings with a space. If two directories are
166 on the same device, only the first directory
167 is monitored.
168
169 &lt;threshold&gt; is:
170 Either the minimum available disk space,
171 the minimum number of free inodes, or
172 both. You must specify at least one. To
173 omit one or the other, simply omit the value.
174 Specify the threshold using G, M, K for Gbytes,
175 Mbytes, and Kbytes, respectively. If you do
176 not specify G, M, or K, Kbytes is assumed by
177 default. Do not use GB, MB, or KB.
178 </pre>
179<p>
180 </p>
181<p>
182 Here are some examples:
183 </p>
184<pre class="literallayout">
185 BB_DISKMON_DIRS = "ABORT,${TMPDIR},1G,100K WARN,${SSTATE_DIR},1G,100K"
186 BB_DISKMON_DIRS = "STOPTASKS,${TMPDIR},1G"
187 BB_DISKMON_DIRS = "ABORT,${TMPDIR},,100K"
188 </pre>
189<p>
190 The first example works only if you also provide
191 the <a class="link" href="ref-variables-glos.html#var-BB_DISKMON_WARNINTERVAL" title="BB_DISKMON_WARNINTERVAL"><code class="filename">BB_DISKMON_WARNINTERVAL</code></a> variable
192 in the <code class="filename">conf/local.conf</code>.
193 This example causes the build system to immediately
194 abort when either the disk space in <code class="filename">${TMPDIR}</code> drops
195 below 1 Gbyte or the available free inodes drops below
196 100 Kbytes.
197 Because two directories are provided with the variable, the
198 build system also issue a
199 warning when the disk space in the
200 <code class="filename">${SSTATE_DIR}</code> directory drops
201 below 1 Gbyte or the number of free inodes drops
202 below 100 Kbytes.
203 Subsequent warnings are issued during intervals as
204 defined by the <code class="filename">BB_DISKMON_WARNINTERVAL</code>
205 variable.
206 </p>
207<p>
208 The second example stops the build after all currently
209 executing tasks complete when the minimum disk space
210 in the <code class="filename">${TMPDIR}</code> directory drops
211 below 1 Gbyte.
212 No disk monitoring occurs for the free inodes in this case.
213 </p>
214<p>
215 The final example immediately aborts the build when the
216 number of free inodes in the <code class="filename">${TMPDIR}</code> directory
217 drops below 100 Kbytes.
218 No disk space monitoring for the directory itself occurs
219 in this case.
220 </p>
221</dd>
222<dt>
223<a name="var-BB_DISKMON_WARNINTERVAL"></a>BB_DISKMON_WARNINTERVAL</dt>
224<dd>
225<p>
226 Defines the disk space and free inode warning intervals.
227 To set these intervals, define the variable in your
228 <code class="filename">conf/local.conf</code> file in the
229 <a class="link" href="../dev-manual/build-directory.html" target="_self">Build Directory</a>.
230 </p>
231<p>
232 If you are going to use the
233 <code class="filename">BB_DISKMON_WARNINTERVAL</code> variable, you must
234 also use the
235 <a class="link" href="ref-variables-glos.html#var-BB_DISKMON_DIRS" title="BB_DISKMON_DIRS"><code class="filename">BB_DISKMON_DIRS</code></a> variable
236 and define its action as "WARN".
237 During the build, subsequent warnings are issued each time
238 disk space or number of free inodes further reduces by
239 the respective interval.
240 </p>
241<p>
242 If you do not provide a <code class="filename">BB_DISKMON_WARNINTERVAL</code>
243 variable and you do use <code class="filename">BB_DISKMON_DIRS</code> with
244 the "WARN" action, the disk monitoring interval defaults to
245 the following:
246 </p>
247<pre class="literallayout">
248 BB_DISKMON_WARNINTERVAL = "50M,5K"
249 </pre>
250<p>
251 </p>
252<p>
253 When specifying the variable in your configuration file,
254 use the following form:
255 </p>
256<pre class="literallayout">
257 BB_DISKMON_WARNINTERVAL = "&lt;disk_space_interval&gt;,&lt;disk_inode_interval&gt;"
258
259 where:
260
261 &lt;disk_space_interval&gt; is:
262 An interval of memory expressed in either
263 G, M, or K for Gbytes, Mbytes, or Kbytes,
264 respectively. You cannot use GB, MB, or KB.
265
266 &lt;disk_inode_interval&gt; is:
267 An interval of free inodes expressed in either
268 G, M, or K for Gbytes, Mbytes, or Kbytes,
269 respectively. You cannot use GB, MB, or KB.
270 </pre>
271<p>
272 </p>
273<p>
274 Here is an example:
275 </p>
276<pre class="literallayout">
277 BB_DISKMON_DIRS = "WARN,${SSTATE_DIR},1G,100K"
278 BB_DISKMON_WARNINTERVAL = "50M,5K"
279 </pre>
280<p>
281 These variables cause the OpenEmbedded build system to
282 issue subsequent warnings each time the available
283 disk space further reduces by 50 Mbytes or the number
284 of free inodes further reduces by 5 Kbytes in the
285 <code class="filename">${SSTATE_DIR}</code> directory.
286 Subsequent warnings based on the interval occur each time
287 a respective interval is reached beyond the intial warning
288 (i.e. 1 Gbytes and 100 Kbytes).
289 </p>
290</dd>
291<dt>
292<a name="var-BBCLASSEXTEND"></a>BBCLASSEXTEND</dt>
293<dd>
294<p>
295 Allows you to extend a recipe so that it builds variants of the software.
296 Common variants for recipes exist such as "natives" like <code class="filename">quilt-native</code>,
297 which is a copy of quilt built to run on the build system;
298 "crosses" such as <code class="filename">gcc-cross</code>,
299 which is a compiler built to run on the build machine but produces binaries
300 that run on the target <a class="link" href="ref-variables-glos.html#var-MACHINE" title="MACHINE"><code class="filename">MACHINE</code></a>;
301 "nativesdk", which targets the SDK machine instead of <code class="filename">MACHINE</code>;
302 and "mulitlibs" in the form "<code class="filename">multilib:&lt;multilib_name&gt;</code>".
303 </p>
304<p>
305 To build a different variant of the recipe with a minimal amount of code, it usually
306 is as simple as adding the following to your recipe:
307 </p>
308<pre class="literallayout">
309 BBCLASSEXTEND =+ "native nativesdk"
310 BBCLASSEXTEND =+ "multilib:&lt;multilib_name&gt;"
311 </pre>

315<dt>
316<a name="var-BBMASK"></a>BBMASK</dt>
317<dd>
318<p>Prevents BitBake from processing recipes and recipe append files.
319 You can use the <code class="filename">BBMASK</code> variable to "hide"
320 these <code class="filename">.bb</code> and <code class="filename">.bbappend</code> files.
321 BitBake ignores any recipe or recipe append files that match the expression.
322 It is as if BitBake does not see them at all.
323 Consequently, matching files are not parsed or otherwise used by
324 BitBake.</p>
325<p>The value you provide is passed to python's regular expression compiler.
326 For complete syntax information, see python's documentation at
327 <a class="ulink" href="http://docs.python.org/release/2.3/lib/re-syntax.html" target="_self">http://docs.python.org/release/2.3/lib/re-syntax.html</a>.
328 The expression is compared against the full paths to the files.
329 For example, the following uses a complete regular expression to tell
330 BitBake to ignore all recipe and recipe append files in the
331 <code class="filename">.*/meta-ti/recipes-misc/</code> directory:
332 </p>
333<pre class="literallayout">
334 BBMASK = ".*/meta-ti/recipes-misc/"
335 </pre>
336<p>Use the <code class="filename">BBMASK</code> variable from within the
337 <code class="filename">conf/local.conf</code> file found
338 in the <a class="link" href="../dev-manual/build-directory.html" target="_self">Build Directory</a>.</p>

348 These names are used to find the other <code class="filename">BBFILE_*</code>

352 </p></dd>
353<dt>
354<a name="var-BBFILE_PATTERN"></a>BBFILE_PATTERN</dt>
355<dd><p>Variable that expands to match files from <code class="filename">BBFILES</code> in a particular layer.
356 This variable is used in the <code class="filename">conf/layer.conf</code> file and must
357 be suffixed with the name of the specific layer (e.g.
358 <code class="filename">BBFILE_PATTERN_emenlow</code>).</p></dd>
359<dt>
360<a name="var-BBFILE_PRIORITY"></a>BBFILE_PRIORITY</dt>
361<dd>
362<p>Assigns the priority for recipe files in each layer.</p>
363<p>This variable is useful in situations where the same recipe appears in
364 more than one layer.
365 Setting this variable allows you to prioritize a
366 layer against other layers that contain the same recipe - effectively
367 letting you control the precedence for the multiple layers.
368 The precedence established through this variable stands regardless of a
369 recipe's version (<code class="filename">PV</code> variable).
370 For example, a layer that has a recipe with a higher <code class="filename">PV</code> value but for
371 which the <code class="filename">BBFILE_PRIORITY</code> is set to have a lower precedence still has a
372 lower precedence.</p>
373<p>A larger value for the <code class="filename">BBFILE_PRIORITY</code> variable results in a higher
374 precedence.
375 For example, the value 6 has a higher precedence than the value 5.
376 If not specified, the <code class="filename">BBFILE_PRIORITY</code> variable is set based on layer
377 dependencies (see the
378 <code class="filename"><a class="link" href="ref-variables-glos.html#var-LAYERDEPENDS" title="LAYERDEPENDS">LAYERDEPENDS</a></code> variable for
379 more information.
380 The default priority, if unspecified
381 for a layer with no dependencies, is the lowest defined priority + 1
382 (or 1 if no priorities are defined).</p>

472<p>
473 Identifies editable or configurable files that are part of a package.
474 If the Package Management System (PMS) is being used to update
475 packages on the target system, it is possible that
476 configuration files you have changed after the original installation
477 and that you now want to remain unchanged are overwritten.
478 In other words, editable files might exist in the package that you do not
479 want reset as part of the package update process.
480 You can use the <code class="filename">CONFFILES</code> variable to list the files in the
481 package that you wish to prevent the PMS from overwriting during this update process.
482 </p>
483<p>
484 To use the <code class="filename">CONFFILES</code> variable, provide a package name
485 override that identifies the resulting package.
486 Then, provide a space-separated list of files.
487 Here is an example:
488 </p>
489<pre class="literallayout">
490 CONFFILES_${PN} += "${sysconfdir}/file1 \
491 ${sysconfdir}/file2 ${sysconfdir}/file3"
492 </pre>
493<p>
494 </p>
495<p>
496 A relationship exists between the <code class="filename">CONFFILES</code> and
497 <code class="filename"><a class="link" href="ref-variables-glos.html#var-FILES" title="FILES">FILES</a></code> variables.
498 The files listed within <code class="filename">CONFFILES</code> must be a subset of
499 the files listed within <code class="filename">FILES</code>.
500 Because the configuration files you provide with <code class="filename">CONFFILES</code>
501 are simply being identified so that the PMS will not overwrite them,
502 it makes sense that
503 the files must already be included as part of the package through the
504 <code class="filename">FILES</code> variable.
505 </p>

507<h3 class="title">Note</h3>
508 When specifying paths as part of the <code class="filename">CONFFILES</code> variable,
509 it is good practice to use appropriate path variables.
510 For example, <code class="filename">${sysconfdir}</code> rather than
511 <code class="filename">/etc</code> or <code class="filename">${bindir}</code> rather

769
770"tools-sdk" - Adds development tools such as gcc, make,
771 pkgconfig and so forth.
772
773"tools-debug" - Adds debugging tools such as gdb and
774 strace.
775
776"tools-profile" - Adds profiling tools such as oprofile,
777 exmap, lttng and valgrind (x86 only).
778
779"tools-testapps" - Adds useful testing tools such as
780 ts_print, aplay, arecord and so
781 forth.
782
783"debug-tweaks" - Makes an image suitable for development.
784 For example, ssh root access has a blank
785 password. You should remove this feature
786 before you produce a production image.

868 Extends the search path the OpenEmbedded build system uses when
869 looking for files and patches as it processes recipes.
870 The directories BitBake uses when it processes recipes is defined by the
871 <a class="link" href="ref-variables-glos.html#var-FILESPATH" title="FILESPATH"><code class="filename">FILESPATH</code></a> variable.
872 You can add directories to the search path by defining the
873 <code class="filename">FILESEXTRAPATHS</code> variable.
874 </p>
875<p>
876 To add paths to the search order, provide a list of directories and separate
877 each path using a colon character as follows:
878 </p>
879<pre class="literallayout">
880 FILESEXTRAPATHS_prepend := "path_1:path_2:path_3:"
881 </pre>
882<p>
883 Typically, you want your directories search first.
884 To make sure that happens, use <code class="filename">_prepend</code> and
885 the immediate expansion (<code class="filename">:=</code>) operator as shown in the
886 previous example.
887 Finally, to maintain the integrity of the <code class="filename">FILESPATH</code> variable,
888 you must include the appropriate beginning or ending (as needed) colon character.
889 </p>
890<p>
891 The <code class="filename">FILESEXTRAPATHS</code> variable is intended for use in
892 <code class="filename">.bbappend</code> files to include any additional files provided in that layer.
893 You typically accomplish this with the following:
894 </p>
895<pre class="literallayout">
896 FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"
897 </pre>
898<p>

905 The default set of directories the OpenEmbedded build system uses
906 when searching for patches and files.
907 During the build process, BitBake searches each directory in
908 <code class="filename">FILESPATH</code> in the specified order when looking for
909 files and patches specified by each <code class="filename">file://</code> URI in a recipe.
910 </p>
911<p>
912 The default value for the <code class="filename">FILESPATH</code> variable is defined
913 in the <code class="filename">base.bbclass</code> class found in
914 <code class="filename">meta/classes</code> in the
915 <a class="link" href="../dev-manual/source-directory.html" target="_self">Source Directory</a>:
916 </p>
917<pre class="literallayout">

922 </pre>
923<p>
924 Do not hand-edit the <code class="filename">FILESPATH</code> variable.
925 If you want to extend the set of pathnames that BitBake uses when searching for
926 files and patches, use the
927 <a class="link" href="ref-variables-glos.html#var-FILESEXTRAPATHS" title="FILESEXTRAPATHS"><code class="filename">FILESEXTRAPATHS</code></a> variable.

934 your configuration for the packaging process.
935 For example, suppose you need a consistent set of custom permissions for
936 a set of groups and users across an entire work project.
937 It is best to do this in the packages themselves but this is not always
938 possible.
939 </p>
940<p>
941 By default, the OpenEmbedded build system uses the <code class="filename">fs-perms.txt</code>, which
942 is located in the <code class="filename">meta/files</code> folder in the
943 <a class="link" href="../dev-manual/source-directory.html" target="_self">Source Directory</a>.
944 If you create your own file permissions setting table, you should place it in your
945 layer or the distros layer.
946 </p>
947<p>
948 You define the <code class="filename">FILESYSTEM_PERMS_TABLES</code> variable in the
949 <code class="filename">conf/local.conf</code> file, which is found in the
950 <a class="link" href="../dev-manual/build-directory.html" target="_self">Build Directory</a>, to
951 point to your custom <code class="filename">fs-perms.txt</code>.
952 You can specify more than a single file permissions setting table.
953 The paths you specify to these files must be defined within the
954 <code class="filename">BBPATH</code> variable.
955 </p>
956<p>
957 For guidance on how to create your own file permissions settings table file,

1001 Specifies the packages to install into an image.
1002 The <code class="filename">IMAGE_INSTALL</code> variable is a mechanism for an image
1003 recipe and you should use it with care to avoid ordering issues.
1004 </p>
1005<p>
1006 Image recipes set <code class="filename">IMAGE_INSTALL</code> to specify the
1007 packages to install into an image through <code class="filename">image.bbclass</code>.
1008 Additionally, "helper" classes exist, such as <code class="filename">core-image.bbclass</code>,
1009 that can take
1010 <code class="filename"><a class="link" href="ref-variables-glos.html#var-IMAGE_FEATURES" title="IMAGE_FEATURES">IMAGE_FEATURES</a></code> lists
1011 and turn these into auto-generated entries in
1012 <code class="filename">IMAGE_INSTALL</code> in addition to its default contents.
1013 </p>
1014<p>
1015 Using <code class="filename">IMAGE_INSTALL</code> with the <code class="filename">+=</code>
1016 operator from the <code class="filename">/conf/local.conf</code> file or from within
1017 an image recipe is not recommended as it can cause ordering issues.
1018 Since <code class="filename">core-image.bbclass</code> sets <code class="filename">IMAGE_INSTALL</code>
1019 to a default value using the <code class="filename">?=</code> operator, using a
1020 <code class="filename">+=</code> operation against <code class="filename">IMAGE_INSTALL</code>
1021 will result in unexpected behavior when used in
1022 <code class="filename">/conf/local.conf</code>.
1023 Furthermore, the same operation from with an image recipe may or may not
1024 succeed depending on the specific situation.
1025 In both these cases, the behavior is contrary to how most users expect
1026 the <code class="filename">+=</code> operator to work.
1027 </p>
1028<p>
1029 When you use this variable, it is best to use it as follows:
1030 </p>
1031<pre class="literallayout">
1032 IMAGE_INSTALL_append = " package-name"
1033 </pre>
1034<p>

1040<a name="var-IMAGE_OVERHEAD_FACTOR"></a>IMAGE_OVERHEAD_FACTOR</dt>
1041<dd>
1042<p>
1043 Defines a multiplier that the build system applies to the initial image
1044 size for cases when the multiplier times the returned disk usage value
1045 for the image is greater than the sum of
1046 <code class="filename"><a class="link" href="ref-variables-glos.html#var-IMAGE_ROOTFS_SIZE" title="IMAGE_ROOTFS_SIZE">IMAGE_ROOTFS_SIZE</a></code>
1047 and
1048 <code class="filename"><a class="link" href="ref-variables-glos.html#var-IMAGE_ROOTFS_EXTRA_SPACE" title="IMAGE_ROOTFS_EXTRA_SPACE">IMAGE_ROOTFS_EXTRA_SPACE</a></code>.
1049 The result of the multiplier applied to the initial image size creates
1050 free disk space in the image as overhead.
1051 By default, the build process uses a multiplier of 1.3 for this variable.
1052 This default value results in 30% free disk space added to the image when this
1053 method is used to determine the final generated image size.
1054 You should be aware that post install scripts and the package management
1055 system uses disk space inside this overhead area.
1056 Consequently, the multiplier does not produce an image with
1057 all the theoretical free disk space.
1058 See <code class="filename"><a class="link" href="ref-variables-glos.html#var-IMAGE_ROOTFS_SIZE" title="IMAGE_ROOTFS_SIZE">IMAGE_ROOTFS_SIZE</a></code>
1059 for information on how the build system determines the overall image size.
1060 </p>
1061<p>
1062 The default 30% free disk space typically gives the image enough room to boot
1063 and allows for basic post installs while still leaving a small amount of
1064 free disk space.
1065 If 30% free space is inadequate, you can increase the default value.
1066 For example, the following setting gives you 50% free space added to the image:
1067 </p>
1068<pre class="literallayout">
1069 IMAGE_OVERHEAD_FACTOR = "1.5"
1070 </pre>
1071<p>
1072 </p>
1073<p>
1074 Alternatively, you can ensure a specific amount of free disk space is added
1075 to the image by using
1076 <code class="filename"><a class="link" href="ref-variables-glos.html#var-IMAGE_ROOTFS_EXTRA_SPACE" title="IMAGE_ROOTFS_EXTRA_SPACE">IMAGE_ROOTFS_EXTRA_SPACE</a></code>
1077 the variable.

1081<a name="var-IMAGE_ROOTFS_EXTRA_SPACE"></a>IMAGE_ROOTFS_EXTRA_SPACE</dt>
1082<dd>
1083<p>
1084 Defines additional free disk space created in the image in Kbytes.
1085 By default, this variable is set to "0".
1086 This free disk space is added to the image after the build system determines
1087 the image size as described in
1088 <code class="filename"><a class="link" href="ref-variables-glos.html#var-IMAGE_ROOTFS_SIZE" title="IMAGE_ROOTFS_SIZE">IMAGE_ROOTFS_SIZE</a></code>.
1089 </p>
1090<p>
1091 This variable is particularly useful when you want to ensure that a
1092 specific amount of free disk space is available on a device after an image
1093 is installed and running.
1094 For example, to be sure 5 Gbytes of free disk space is available, set the
1095 variable as follows:
1096 </p>
1097<pre class="literallayout">
1098 IMAGE_ROOTFS_EXTRA_SPACE = "5242880"
1099 </pre>
1100<p>
1101 </p>
1102</dd>
1103<dt>
1104<a name="var-IMAGE_ROOTFS_SIZE"></a>IMAGE_ROOTFS_SIZE</dt>
1105<dd>
1106<p>
1107 Defines the size in Kbytes for the generated image.
1108 The OpenEmbedded build system determines the final size for the generated
1109 image using an algorithm that takes into account the initial disk space used
1110 for the generated image, a requested size for the image, and requested
1111 additional free disk space to be added to the image.
1112 Programatically, the build system determines the final size of the
1113 generated image as follows:
1114 </p>
1115<pre class="literallayout">
1116 if (image-du * overhead) &lt; rootfs-size:
1117 internal-rootfs-size = rootfs-size + xspace
1118 else:
1119 internal-rootfs-size = (image-du * overhead) + xspace
1120
1121 where:
1122
1123 image-du = Returned value of the du command on
1124 the image.
1125
1126 overhead = IMAGE_OVERHEAD_FACTOR
1127
1128 rootfs-size = IMAGE_ROOTFS_SIZE
1129
1130 internal-rootfs-size = Initial root filesystem
1131 size before any modifications.
1132
1133 xspace = IMAGE_ROOTFS_EXTRA_SPACE

1142<p>Helps define the recipe revision for recipes that share
1143 a common <code class="filename">include</code> file.
1144 You can think of this variable as part of the recipe revision
1145 as set from within an include file.</p>
1146<p>Suppose, for example, you have a set of recipes that
1147 are used across several projects.
1148 And, within each of those recipes the revision
1149 (its <code class="filename">PR</code> value) is set accordingly.
1150 In this case, when the revision of those recipes changes
1151 the burden is on you to find all those recipes and
1152 be sure that they get changed to reflect the updated
1153 version of the recipe.
1154 In this scenario, it can get complicated when recipes
1155 used in many places and that provide common functionality
1156 are upgraded to a new revision.</p>
1157<p>A more efficient way of dealing with this situation is
1158 to set the <code class="filename">INC_PR</code> variable inside
1159 the <code class="filename">include</code> files that the recipes
1160 share and then expand the <code class="filename">INC_PR</code>
1161 variable within the recipes to help
1162 define the recipe revision.
1163 </p>
1164<p>
1165 The following provides an example that shows how to use
1166 the <code class="filename">INC_PR</code> variable
1167 given a common <code class="filename">include</code> file that
1168 defines the variable.
1169 Once the variable is defined in the
1170 <code class="filename">include</code> file, you can use the
1171 variable to set the <code class="filename">PR</code> values in
1172 each recipe.
1173 You will notice that when you set a recipe's
1174 <code class="filename">PR</code> you can provide more granular
1175 revisioning by appending values to the
1176 <code class="filename">INC_PR</code> variable:
1177 </p>
1178<pre class="literallayout">
1179recipes-graphics/xorg-font/xorg-font-common.inc:INC_PR = "r2"
1180recipes-graphics/xorg-font/encodings_1.0.4.bb:PR = "${INC_PR}.1"
1181recipes-graphics/xorg-font/font-util_1.3.0.bb:PR = "${INC_PR}.0"
1182recipes-graphics/xorg-font/font-alias_1.0.3.bb:PR = "${INC_PR}.3"
1183 </pre>
1184<p>
1185 The first line of the example establishes the baseline
1186 revision to be used for all recipes that use the
1187 <code class="filename">include</code> file.
1188 The remaining lines in the example are from individual

1250 A regular expression used by the build process to explicitly identify the kernel
1251 branch that is validated, patched and configured during a build.
1252 The <code class="filename">KBRANCH</code> variable is optional.
1253 You can use it to trigger checks to ensure the exact kernel branch you want is
1254 being used by the build process.
1255 </p>
1256<p>
1257 Values for this variable are set in the kernel's recipe file and the kernel's
1258 append file.
1259 For example, if you are using the Yocto Project kernel that is based on the
1260 Linux 3.4 kernel, the kernel recipe file is the
1261 <code class="filename">meta/recipes-kernel/linux/linux-yocto_3.4.bb</code> file.
1262 Following is the default value for <code class="filename">KBRANCH</code> and the default
1263 override for the architectures the Yocto Project supports:
1264 </p>
1265<pre class="literallayout">
1266 KBRANCH_DEFAULT = "standard/base"
1267 KBRANCH = "${KBRANCH_DEFAULT}"
1268 </pre>
1269<p>
1270 This branch exists in the <code class="filename">linux-yocto-3.4</code> kernel Git
1271 repository <a class="ulink" href="http://git.yoctoproject.org/cgit.cgi/linux-yocto-3.4/refs/heads" target="_self">http://git.yoctoproject.org/cgit.cgi/linux-yocto-3.4/refs/heads</a>.
1272 </p>
1273<p>
1274 This variable is also used from the kernel's append file to identify the kernel
1275 branch specific to a particular machine or target hardware.
1276 The kernel's append file is located in the BSP layer for a given machine.
1277 For example, the kernel append file for the Crown Bay BSP is in the
1278 <code class="filename">meta-intel</code> Git repository and is named
1279 <code class="filename">meta-crownbay/recipes-kernel/linux/linux-yocto_3.4.bbappend</code>.
1280 Here are the related statements from the append file:
1281 </p>
1282<pre class="literallayout">
1283 COMPATIBLE_MACHINE_crownbay = "crownbay"
1284 KMACHINE_crownbay = "crownbay"
1285 KBRANCH_crownbay = "standard/crownbay"
1286
1287 COMPATIBLE_MACHINE_crownbay-noemgd = "crownbay-noemgd"
1288 KMACHINE_crownbay-noemgd = "crownbay"
1289 KBRANCH_crownbay-noemgd = "standard/crownbay"
1290 </pre>
1291<p>
1292 The <code class="filename">KBRANCH_*</code> statements identify the kernel branch to
1293 use when building for the Crown Bay BSP.
1294 In this case there are two identical statements: one for each type of
1295 Crown Bay machine.

1302 In the OpenEmbedded build system, the default Board Support Packages (BSPs)
1303 metadata is provided through
1304 the <code class="filename">KMACHINE</code> and <code class="filename">KBRANCH</code> variables.
1305 You can use the <code class="filename">KERNEL_FEATURES</code> variable to further
1306 add metadata for all BSPs.</p>
1307<p>The metadata you add through this variable includes config fragments and
1308 features descriptions,
1309 which usually includes patches as well as config fragments.
1310 You typically override the <code class="filename">KERNEL_FEATURES</code> variable
1311 for a specific machine.
1312 In this way, you can provide validated, but optional, sets of kernel
1313 configurations and features.</p>
1314<p>For example, the following adds <code class="filename">netfilter</code> to all
1315 the Yocto Project kernels and adds sound support to the <code class="filename">qemux86</code>

1337 The machine as known by the kernel.
1338 Sometimes the machine name used by the kernel does not match the machine name
1339 used by the OpenEmbedded build system.
1340 For example, the machine name that the OpenEmbedded build system understands as
1341 <code class="filename">qemuarm</code> goes by a different name in the Linux Yocto kernel.
1342 The kernel understands that machine as <code class="filename">arm_versatile926ejs</code>.
1343 For cases like these, the <code class="filename">KMACHINE</code> variable maps the
1344 kernel machine name to the OpenEmbedded build system machine name.
1345 </p>
1346<p>
1347 Kernel machine names are initially defined in the
1348 <a class="ulink" href="http://git.yoctoproject.org/cgit.cgi" target="_self">Yocto Linux Kernel</a> in
1349 the <code class="filename">meta</code> branch.
1350 From the <code class="filename">meta</code> branch, look in
1351 the <code class="filename">meta/cfg/kernel-cache/bsp/&lt;bsp_name&gt;/&lt;bsp-name&gt;-&lt;kernel-type&gt;.scc</code> file.
1352 For example, from the <code class="filename">meta</code> branch in the
1353 <code class="filename">linux-yocto-3.0</code> kernel, the
1354 <code class="filename">meta/cfg/kernel-cache/bsp/cedartrail/cedartrail-standard.scc</code> file
1355 has the following:
1356 </p>
1357<pre class="literallayout">
1358 define KMACHINE cedartrail
1359 define KTYPE standard
1360 define KARCH i386
1361
1362 include ktypes/standard
1363 branch cedartrail
1364
1365 include cedartrail.scc
1366 </pre>
1367<p>
1368 You can see that the kernel understands the machine name for the Cedar Trail BSP as
1369 <code class="filename">cedartrail</code>.
1370 </p>
1371<p>
1372 If you look in the Cedar Trail BSP layer in the <code class="filename">meta-intel</code> source
1373 repository at <code class="filename">meta-cedartrail/recipes-kernel/linux/linux-yocto_3.0.bbappend</code>,
1374 you will find the following statements among others:
1375 </p>
1376<pre class="literallayout">
1377 COMPATIBLE_MACHINE_cedartrail = "cedartrail"
1378 KMACHINE_cedartrail = "cedartrail"
1379 KBRANCH_cedartrail = "yocto/standard/cedartrail"
1380 KERNEL_FEATURES_append_cedartrail += "bsp/cedartrail/cedartrail-pvr-merge.scc"
1381 KERNEL_FEATURES_append_cedartrail += "cfg/efi-ext.scc"
1382
1383 COMPATIBLE_MACHINE_cedartrail-nopvr = "cedartrail"
1384 KMACHINE_cedartrail-nopvr = "cedartrail"
1385 KBRANCH_cedartrail-nopvr = "yocto/standard/cedartrail"
1386 KERNEL_FEATURES_append_cedartrail-nopvr += " cfg/smp.scc"
1387 </pre>
1388<p>
1389 The <code class="filename">KMACHINE</code> statements in the kernel's append file make sure that
1390 the OpenEmbedded build system and the Yocto Linux kernel understand the same machine
1391 names.
1392 </p>
1393<p>
1394 This append file uses two <code class="filename">KMACHINE</code> statements.
1395 The first is not really necessary but does ensure that the machine known to the
1396 OpenEmbedded build system as <code class="filename">cedartrail</code> maps to the machine
1397 in the kernel also known as <code class="filename">cedartrail</code>:
1398 </p>
1399<pre class="literallayout">
1400 KMACHINE_cedartrail = "cedartrail"
1401 </pre>
1402<p>
1403 </p>
1404<p>
1405 The second statement is a good example of why the <code class="filename">KMACHINE</code> variable
1406 is needed.
1407 In this example, the OpenEmbedded build system uses the <code class="filename">cedartrail-nopvr</code>
1408 machine name to refer to the Cedar Trail BSP that does not support the propriatory
1409 PowerVR driver.
1410 The kernel, however, uses the machine name <code class="filename">cedartrail</code>.
1411 Thus, the append file must map the <code class="filename">cedartrail-nopvr</code> machine name to
1412 the kernel's <code class="filename">cedartrail</code> name:
1413 </p>
1414<pre class="literallayout">
1415 KMACHINE_cedartrail-nopvr = "cedartrail"
1416 </pre>
1417<p>
1418 </p>
1419<p>
1420 BSPs that ship with the Yocto Project release provide all mappings between the Yocto
1421 Project kernel machine names and the OpenEmbedded machine names.
1422 Be sure to use the <code class="filename">KMACHINE</code> if you create a BSP and the machine
1423 name you use is different than that used in the kernel.

1624 However, because this is a "machine essential" variable, the list of
1625 packages are essential for the machine to boot.
1626 The impact of this variable affects images based on

1633 variable with the exception that the image being built does not have a build
1634 dependency on the variable's list of packages.
1635 In other words, the image will still build if a package in this list is not found.
1636 Typically, this variable is used to handle essential kernel modules, whose
1637 functionality may be selected to be built into the kernel rather than as a module,
1638 in which case a package will not be produced.
1639 </p>
1640<p>
1641 Consider an example where you have a custom kernel where a specific touchscreen
1642 driver is required for the machine to be usable.
1643 However, the driver can be built as a module or
1644 into the kernel depending on the kernel configuration.
1645 If the driver is built as a module, you want it to be installed.
1646 But, when the driver is built into the kernel, you still want the
1647 build to succeed.
1648 This variable sets up a "recommends" relationship so that in the latter case,
1649 the build will not fail due to the missing package.
1650 To accomplish this, assuming the package for the module was called
1651 <code class="filename">kernel-module-ab123</code>, you would use the
1652 following in the machine's <code class="filename">.conf</code> configuration
1653 file:
1654 </p>
1655<pre class="literallayout">

1673 </p>
1674<p>
1675 This variable affects all images based on
1676 <code class="filename">packagegroup-base</code>, which does not include the

1678 images.

1684 dependency on the variable's list of packages.
1685 In other words, the image will not build if a file in this list is not found.
1686 </p>
1687<p>
1688 An example is a machine that has WiFi capability but is not essential
1689 For the machine to boot the image.
1690 However, if you are building a more fully-featured image, you want to enable
1691 the WiFi.
1692 The package containing the firmware for the WiFi hardware is always
1693 expected to exist, so it is acceptable for the build process to depend upon
1694 finding the package.
1695 In this case, assuming the package for the firmware was called
1696 <code class="filename">wifidriver-firmware</code>, you would use the following in the
1697 <code class="filename">.conf</code> file for the machine:

1728 An example is a machine that has WiFi capability but is not essential
1729 For the machine to boot the image.
1730 However, if you are building a more fully-featured image, you want to enable
1731 WiFi.
1732 In this case, the package containing the WiFi kernel module will not be produced
1733 if the WiFi driver is built into the kernel, in which case you still want the
1734 build to succeed instead of failing as a result of the package not being found.
1735 To accomplish this, assuming the package for the module was called

1906 This variable provides a means of enabling or disabling
1907 features of a recipe on a per-recipe basis.
1908 The <code class="filename">PACKAGECONFIG</code>
1909 variable itself specifies a space-separated list of the
1910 features to enable.
1911 The features themselves are specified as flags on the
1912 <code class="filename">PACKAGECONFIG</code> variable.
1913 You can provide up to four arguments, which are separated by
1914 commas, to determine the behavior of each feature
1915 when it is enabled or disabled.
1916 You can omit any argument you like but must retain the
1917 separating commas.
1918 The arguments specify the following:

1940<p>
1941 Consider the following example taken from the
1942 <code class="filename">librsvg</code> recipe.
1943 In this example the feature is <code class="filename">croco</code>, which
1944 has three arguments that determine the feature's behavior.
1945 </p>
1946<pre class="literallayout">
1947 PACKAGECONFIG ??= "croco"
1948 PACKAGECONFIG[croco] = "--with-croco,--without-croco,libcroco"
1949 </pre>
1950<p>
1951 The <code class="filename">--with-croco</code> and
1952 <code class="filename">libcroco</code> arguments apply only if
1953 the feature is enabled.
1954 In this case, <code class="filename">--with-croco</code> is
1955 added to the configure script argument list and
1956 <code class="filename">libcroco</code> is added to
1957 <code class="filename"><a class="link" href="ref-variables-glos.html#var-DEPENDS" title="DEPENDS">DEPENDS</a></code>.
1958 On the other hand, if the feature is disabled say through
1959 a <code class="filename">.bbappend</code> file in another layer, then
1960 the second argument <code class="filename">--without-croco</code> is
1961 added to the configure script rather than
1962 <code class="filename">--with-croco</code>.

1979 A promise that your recipe satisfies runtime dependencies
1980 for optional modules that are found in other recipes.
1981 <code class="filename">PACKAGES_DYNAMIC</code>
1982 does not actually satisfy the dependencies, it only states that
1983 they should be satisfied.
1984 For example, if a hard, runtime dependency
1985 (<code class="filename">RDEPENDS</code>) of another package is satisfied
1986 at build time through the <code class="filename">PACKAGES_DYNAMIC</code>
1987 variable, but a package with the module name is never actually
1988 produced, then the other package will be broken.
1989 Thus, if you attempt to include that package in an image,
1990 you will get a dependency failure from the packaging system
1991 during <code class="filename">do_rootfs</code>.
1992 Typically, if there is a chance that such a situation can
1993 occur and the package that is not created is valid
1994 without the dependency being satisfied, then you should use
1995 <code class="filename">RRECOMMENDS</code> (a soft runtime dependency)
1996 instead of <code class="filename">RDEPENDS</code>.
1997 </p>
1998<p>
1999 For an example of how to use the <code class="filename">PACKAGES_DYNAMIC</code>
2000 variable when you are splitting packages, see the

2019 This variable is comprised of the following:

2027<dd>
2028<p>This variable can have two separate functions depending on the context: a recipe
2029 name or a resulting package name.</p>
2030<p><code class="filename">PN</code> refers to a recipe name in the context of a file used
2031 by the OpenEmbedded build system as input to create a package.
2032 The name is normally extracted from the recipe file name.
2033 For example, if the recipe is named
2034 <code class="filename">expat_2.0.1.bb</code>, then the default value of <code class="filename">PN</code>
2035 will be "expat".</p>
2036<p>
2037 The variable refers to a package name in the context of a file created or produced by the
2038 OpenEmbedded build system.</p>
2039<p>If applicable, the <code class="filename">PN</code> variable also contains any special
2040 suffix or prefix.
2041 For example, using <code class="filename">bash</code> to build packages for the native
2042 machine, <code class="filename">PN</code> is <code class="filename">bash-native</code>.
2043 Using <code class="filename">bash</code> to build packages for the target and for Multilib,
2044 <code class="filename">PN</code> would be <code class="filename">bash</code> and
2045 <code class="filename">lib64-bash</code>, respectively.

2054<a name="var-PRINC"></a>PRINC</dt>
2055<dd>
2056<p>Causes the <code class="filename">PR</code> variable of
2057 <code class="filename">.bbappend</code> files to dynamically increment.
2058 This increment minimizes the impact of layer ordering.</p>
2059<p>In order to ensure multiple <code class="filename">.bbappend</code> files can co-exist,
2060 <code class="filename">PRINC</code> should be self referencing.
2061 This variable defaults to 0.</p>
2062<p>Following is an example that increments <code class="filename">PR</code> by two:
2063 </p>
2064<pre class="literallayout">
2065 PRINC := "${@int(PRINC) + 2}"
2066 </pre>
2067<p>
2068 It is adviseable not to use strings such as ".= '.1'" with the variable because
2069 this usage is very sensitive to layer ordering.
2070 Explicit assignments should be avoided as they cannot adequately represent multiple
2071 <code class="filename">.bbappend</code> files.</p>
2072</dd>
2073<dt>
2074<a name="var-PV"></a>PV</dt>
2075<dd><p>The version of the recipe.
2076 The version is normally extracted from the recipe filename.
2077 For example, if the recipe is named
2078 <code class="filename">expat_2.0.1.bb</code>, then the default value of <code class="filename">PV</code>
2079 will be "2.0.1".
2080 <code class="filename">PV</code> is generally not overridden within
2081 a recipe unless it is building an unstable (i.e. development) version from a source code repository
2082 (e.g. Git or Subversion).

2096 If multiple recipes provide an item, this variable
2097 determines which recipe should be given preference.
2098 The variable must always be suffixed with the name of the
2099 provided item, and should be set to the
2100 <code class="filename">PN</code> of the recipe
2101 to which you want to give precedence.
2102 Here is an example:
2103 </p>
2104<pre class="literallayout">
2105 PREFERRED_PROVIDER_virtual/xserver = "xserver-xf86"
2106 </pre>
2107<p>

2109</dd>
2110<dt>
2111<a name="var-PREFERRED_VERSION"></a>PREFERRED_VERSION</dt>
2112<dd>
2113<p>
2114 If there are multiple versions of recipes available, this
2115 variable determines which recipe should be given preference.
2116 The variable must always be suffixed with the <code class="filename">PN</code>
2117 for which to select, and should be set to the
2118 <code class="filename">PV</code> to which you want to give precedence.
2119 You can use the "<code class="filename">%</code>" character as a wildcard
2120 to match any number of characters, which can be useful when
2121 specifying versions that contain long revision number that could
2122 potentially change.
2123 Here are two examples:
2124 </p>
2125<pre class="literallayout">

2140<p>The list of packages that conflict with a package.
2141 Note that the package will not be installed if the conflicting packages are not
2142 first removed.</p>
2143<p>
2144 Like all package-controlling variables, you must always use them in
2145 conjunction with a package name override.
2146 Here is an example:
2147 </p>
2148<pre class="literallayout">
2149 RCONFLICTS_${PN} = "another-conflicting-package-name"
2150 </pre>

2156<dd>
2157<p>
2158 Lists a package's run-time dependencies (i.e. other packages)
2159 that must be installed for the package to be built.
2160 In other words, in order for the package to be built and
2161 run correctly, it depends on the listed packages.
2162 If a package in this list cannot be found, it is probable
2163 that a dependency error would occur before the build.
2164 </p>
2165<p>
2166 The names of the variables you list with
2167 <code class="filename">RDEPENDS</code> must be the names of other
2168 packages as listed in the
2169 <a class="link" href="ref-variables-glos.html#var-PACKAGES" title="PACKAGES"><code class="filename">PACKAGES</code></a>
2170 variable.
2171 You should not list recipe names (<code class="filename">PN</code>).
2172 </p>
2173<p>
2174 Because the <code class="filename">RDEPENDS</code> variable applies
2175 to packages being built, you should
2176 always attach a package name to the variable to specify the
2177 particular run-time package that has the dependency.
2178 For example, suppose you are building a development package
2179 that depends on the <code class="filename">perl</code> package.
2180 In this case, you would use the following
2181 <code class="filename">RDEPENDS</code> statement:
2182 </p>
2183<pre class="literallayout">
2184 RDEPENDS_${PN}-dev += "perl"
2185 </pre>
2186<p>
2187 In the example, the package name
2188 (<code class="filename">${PN}-dev</code>) must appear as it would
2189 in the
2190 <code class="filename"><a class="link" href="ref-variables-glos.html#var-PACKAGES" title="PACKAGES">PACKAGES</a></code>
2191 namespace before any renaming of the output package by
2192 classes like <code class="filename">debian.bbclass</code>.
2193 </p>
2194<p>
2195 In many cases you do not need to explicitly add dependencies
2196 to <code class="filename">RDEPENDS</code> since some automatic
2197 handling occurs:
2198 </p>
2199<div class="itemizedlist"><ul class="itemizedlist" type="disc">
2200<li class="listitem"><p><span class="emphasis"><em><code class="filename">shlibdeps</code></em></span>: If
2201 a run-time package contains a shared library
2202 (<code class="filename">.so</code>), the build
2203 processes the library in order to determine other
2204 libraries to which it is dynamically linked.
2205 The build process adds these libraries to
2206 <code class="filename">RDEPENDS</code> when creating the run-time
2207 package.</p></li>
2208<li class="listitem"><p><span class="emphasis"><em><code class="filename">pcdeps</code></em></span>: If
2209 the package ships a <code class="filename">pkg-config</code>
2210 information file, the build process uses this file
2211 to add items to the <code class="filename">RDEPENDS</code>
2212 variable to create the run-time packages.
2213 </p></li>
2214</ul></div>

2220<dd>
2221<p>
2222 A list of packages that extend the usability of a package being
2223 built.
2224 The package being built does not depend on this list of packages in
2225 order to successfully build, but needs them for the extended usability.
2226 To specify runtime dependencies for packages, see the
2227 <code class="filename"><a class="link" href="ref-variables-glos.html#var-RDEPENDS" title="RDEPENDS">RDEPENDS</a></code> variable.
2228 </p>
2229<p>
2230 The OpenEmbedded build process automatically installs the list of packages
2231 as part of the built package.
2232 However, you can remove them later if you want.
2233 If, during the build, a package from the list cannot be found, the build
2234 process continues without an error.
2235 </p>
2236<p>
2237 Because the <code class="filename">RRECOMMENDS</code> variable applies to packages
2238 being built, you should
2239 always attach an override to the variable to specify the particular package
2240 whose usability is being extended.
2241 For example, suppose you are building a development package that is extended
2242 to support wireless functionality.
2243 In this case, you would use the following:
2244 </p>
2245<pre class="literallayout">
2246 RRECOMMENDS_${PN}-dev += "&lt;wireless_package_name&gt;"
2247 </pre>
2248<p>
2249 In the example, the package name (<code class="filename">${PN}-dev</code>) must
2250 appear as it would in the
2251 <code class="filename"><a class="link" href="ref-variables-glos.html#var-PACKAGES" title="PACKAGES">PACKAGES</a></code> namespace before any

2267 The location in the <a class="link" href="../dev-manual/build-directory.html" target="_self">Build Directory</a>

2269 This location is within the working directory
2270 (<code class="filename"><a class="link" href="ref-variables-glos.html#var-WORKDIR" title="WORKDIR">WORKDIR</a></code>), which
2271 is not static.
2272 The unpacked source location depends on the package name
2273 (<code class="filename"><a class="link" href="ref-variables-glos.html#var-PN" title="PN">PN</a></code>) and
2274 package version (<code class="filename"><a class="link" href="ref-variables-glos.html#var-PV" title="PV">PV</a></code>) as

2337 OpenEmbedded build system to create variants of recipes or packages.
2338 The list specifies the prefixes to strip off during certain circumstances
2339 such as the generation of the <a class="link" href="ref-variables-glos.html#var-BPN" title="BPN"><code class="filename">BPN</code></a> variable.
2340 </p></dd>
2341<dt>
2342<a name="var-SRC_URI"></a>SRC_URI</dt>
2343<dd>
2344<p>The list of source files - local or remote.
2345 This variable tells the OpenEmbedded build system which bits to pull
2346 in for the build and how to pull them in.
2347 For example, if the recipe only needs to fetch a tarball from the
2348 internet, the recipe uses a single <code class="filename">SRC_URI</code> entry.
2349 On the other hand, if the recipe needs to fetch a tarball, apply
2350 two patches, and include a custom file, the recipe would include four
2351 instances of the variable.</p>
2352<p>The following list explains the available URI protocols:
2353 </p>
2354<div class="itemizedlist"><ul class="itemizedlist" type="disc">
2355<li class="listitem">
2356<p><span class="emphasis"><em><code class="filename">file://</code> -</em></span> Fetches files, which is usually

2358 The path is relative to the
2359 <a class="link" href="ref-variables-glos.html#var-FILESPATH" title="FILESPATH"><code class="filename">FILESPATH</code></a>
2360 variable.
2361 Thus, the build system searches, in order, from the following directories,
2362 which are assumed to be a subdirectories of the directory in which the
2363 recipe file resides:
2364 </p>
2365<div class="itemizedlist"><ul class="itemizedlist" type="circle">

2370 Using <code class="filename">bash</code> to build for the target and for Multilib,

2491 contains files that are machine-specific.
2492 If so, the build system automatically changes

2509 Note that if you wish to build a fixed revision and you wish
2510 to avoid performing a query on the remote repository every time
2511 BitBake parses your recipe, you should specify a <code class="filename">SRCREV</code> that is a

2520<p>
2521 Configures the OpenEmbedded build system to search other
2522 mirror locations for prebuilt cache data objects before
2523 building out the data.
2524 This variable works like fetcher
2525 <code class="filename">MIRRORS</code>/<code class="filename">PREMIRRORS</code>
2526 and points to the cache locations to check for the shared
2527 objects.
2528 </p>
2529<p>
2530 You can specify a filesystem directory or a remote URL such
2531 as HTTP or FTP.
2532 The locations you specify need to contain the shared state
2533 cache (sstate-cache) results from previous builds.
2534 The sstate-cache you point to can also be from builds on
2535 other machines.
2536 </p>
2537<p>
2538 If a mirror uses the same structure as
2539 <a class="link" href="ref-variables-glos.html#var-SSTATE_DIR" title="SSTATE_DIR"><code class="filename">SSTATE_DIR</code></a>,
2540 you need to add
2541 "PATH" at the end as shown in the examples below.

2640 to "linux-uclibc" for <code class="filename">uclibc</code>.
2641 For ARM/EABI targets, there are also "linux-gnueabi" and

2647 Specifies which variant of the GNU standard C library (<code class="filename">libc</code>)
2648 to use during the build process.
2649 This variable replaces <code class="filename">POKYLIBC</code>, which is no longer
2650 supported.
2651 </p>
2652<p>
2653 You can select <code class="filename">eglibc</code> or <code class="filename">uclibc</code>.

2667 The toolchain selector.
2668 This variable replaces <code class="filename">POKYMODE</code>, which is no longer
2669 supported.
2670 </p>
2671<p>
2672 The <code class="filename">TCMODE</code> variable selects the external toolchain
2673 built using the OpenEmbedded build system or a few supported combinations of
2674 the upstream GCC or CodeSourcery Labs toolchain.
2675 The variable identifies the <code class="filename">tcmode-*</code> files used in
2676 the <code class="filename">meta/conf/distro/include</code> directory, which is found in the
2677 <a class="link" href="../dev-manual/source-directory.html" target="_self">Source Directory</a>.
2678 </p>
2679<p>
2680 By default, <code class="filename">TCMODE</code> is set to "default", which
2681 chooses the <code class="filename">tcmode-default.inc</code> file.
2682 The variable is similar to
2683 <a class="link" href="ref-variables-glos.html#var-TCLIBC" title="TCLIBC"><code class="filename">TCLIBC</code></a>, which controls
2684 the variant of the GNU standard C library (<code class="filename">libc</code>)
2685 used during the build process: <code class="filename">eglibc</code> or <code class="filename">uclibc</code>.

2688<dt>
2689<a name="var-TMPDIR"></a>TMPDIR</dt>
2690<dd>
2691<p>
2692 This variable is the temporary directory the OpenEmbedded build system
2693 uses when it does its work building images.
2694 By default, the <code class="filename">TMPDIR</code> variable is named
2695 <code class="filename">tmp</code> within the
2696 <a class="link" href="../dev-manual/build-directory.html" target="_self">Build Directory</a>.
2697 </p>
2698<p>
2699 If you want to establish this directory in a location other than the
2700 default, you can uncomment the following statement in the
2701 <code class="filename">conf/local.conf</code> file in the
2702 <a class="link" href="../dev-manual/source-directory.html" target="_self">Source Directory</a>:
2703 </p>

2714 <a class="link" href="../dev-manual/build-directory.html" target="_self">Build Directory</a>.
2715 BitBake automatically sets this variable.
2716 The OpenEmbedded build system uses the Build Directory when building images.

2726<p>
2727 The pathname of the working directory in which the OpenEmbedded build system
2728 builds a recipe.
2729 This directory is located within the
2730 <a class="link" href="ref-variables-glos.html#var-TMPDIR" title="TMPDIR"><code class="filename">TMPDIR</code></a> directory structure and changes
2731 as different packages are built.
2732 </p>
2733<p>
2734 The actual <code class="filename">WORKDIR</code> directory depends on several things:
2735 </p>
2736<div class="itemizedlist"><ul class="itemizedlist" type="disc">
2737<li class="listitem">The temporary directory - <a class="link" href="ref-variables-glos.html#var-TMPDIR" title="TMPDIR"><code class="filename">TMPDIR</code></a>
2738</li>
2739<li class="listitem">The package architecture - <a class="link" href="ref-variables-glos.html#var-PACKAGE_ARCH" title="PACKAGE_ARCH"><code class="filename">PACKAGE_ARCH</code></a>
2740</li>
2741<li class="listitem">The target machine - <a class="link" href="ref-variables-glos.html#var-MACHINE" title="MACHINE"><code class="filename">MACHINE</code></a>
2742</li>
2743<li class="listitem">The target operating system - <a class="link" href="ref-variables-glos.html#var-TARGET_OS" title="TARGET_OS"><code class="filename">TARGET_OS</code></a>
2744</li>
2745<li class="listitem">The recipe name - <a class="link" href="ref-variables-glos.html#var-PN" title="PN"><code class="filename">PN</code></a>
2746</li>
2747<li class="listitem">The recipe version - <a class="link" href="ref-variables-glos.html#var-PV" title="PV"><code class="filename">PV</code></a>
2748</li>
2749<li class="listitem">The recipe revision - <a class="link" href="ref-variables-glos.html#var-PR" title="PR"><code class="filename">PR</code></a>
2750</li>
2751</ul></div>
2752<p>
2753 </p>
2754<p>
2755 For packages that are not dependent on a particular machine,
2756 <code class="filename">WORKDIR</code> is defined as follows:
2757 </p>
2758<pre class="literallayout">
2759 ${TMPDIR}/work/${PACKAGE_ARCH}-poky-${TARGET_OS}/${PN}-${PV}-${PR}
2760 </pre>
2761<p>
2762 As an example, assume a
2763 <a class="link" href="../dev-manual/source-directory.html" target="_self">Source Directory</a> top-level
2764 folder name <code class="filename">poky</code> and a default
2765 <a class="link" href="../dev-manual/build-directory.html" target="_self">Build Directory</a>
2766 at <code class="filename">poky/build</code>.
2767 In this case, the working directory the build system uses to build
2768 the <code class="filename">v86d</code> package is the following:
2769 </p>
2770<pre class="literallayout">
2771 ~/poky/build/tmp/work/qemux86-poky-linux/v86d-01.9-r0
2772 </pre>
2773<p>
2774 </p>
2775<p>
2776 For packages that are dependent on a particular machine, <code class="filename">WORKDIR</code>
2777 is defined slightly different:
2778 </p>
2779<pre class="literallayout">
2780 ${TMPDIR}/work/${MACHINE}-poky-${TARGET_OS}/${PN}-${PV}-${PR}
2781 </pre>
2782<p>
2783 As an example, again assume a Source Directory top-level folder
2784 named <code class="filename">poky</code> and a default Build Directory
2785 at <code class="filename">poky/build</code>.
2786 In this case, the working directory the build system uses to build
2787 the <code class="filename">acl</code> recipe, which is being built for a
2788 MIPS-based device, is the following:
2789 </p>
2790<pre class="literallayout">
2791 ~/poky/build/tmp/work/mips-poky-linux/acl-2.2.51-r2
2792 </pre>

34 While most variables can be used in almost any context such as
35 <code class="filename">.conf</code>, <code class="filename">.bbclass</code>,
36 <code class="filename">.inc</code>, and <code class="filename">.bb</code> files,
37 some variables are often associated with a particular locality or context.

16 By design, the OpenEmbedded build system builds everything from scratch unless
17 BitBake can determine that parts don't need to be rebuilt.
18 Fundamentally, building from scratch is attractive as it means all parts are
19 built fresh and there is no possibility of stale data causing problems.
20 When developers hit problems, they typically default back to building from scratch
21 so they know the state of things from the start.
22 </p>
23<p>
24 Building an image from scratch is both an advantage and a disadvantage to the process.
25 As mentioned in the previous paragraph, building from scratch ensures that
26 everything is current and starts from a known state.
27 However, building from scratch also takes much longer as it generally means
28 rebuilding things that don't necessarily need rebuilt.
29 </p>
30<p>
31 The Yocto Project implements shared state code that supports incremental builds.
32 The implementation of the shared state code answers the following questions that
33 were fundamental roadblocks within the OpenEmbedded incremental build support system:
34 </p>
35<div class="itemizedlist"><ul class="itemizedlist" type="disc">
36<li class="listitem">What pieces of the system have changed and what pieces have not changed?</li>
37<li class="listitem">How are changed pieces of software removed and replaced?</li>
38<li class="listitem">How are pre-built components that don't need to be rebuilt from scratch
39 used when they are available?</li>
40</ul></div>
41<p>
42 </p>
43<p>
44 For the first question, the build system detects changes in the "inputs" to a given task by
45 creating a checksum (or signature) of the task's inputs.
46 If the checksum changes, the system assumes the inputs have changed and the task needs to be
47 rerun.
48 For the second question, the shared state (sstate) code tracks which tasks add which output
49 to the build process.
50 This means the output from a given task can be removed, upgraded or otherwise manipulated.
51 The third question is partly addressed by the solution for the second question
52 assuming the build system can fetch the sstate objects from remote locations and
53 install them if they are deemed to be valid.
54 </p>
55<p>
56 The rest of this section goes into detail about the overall incremental build
57 architecture, the checksums (signatures), shared state, and some tips and tricks.

15<p>
16 Checksums and dependencies, as discussed in the previous section, solve half the
17 problem.
18 The other part of the problem is being able to use checksum information during the build
19 and being able to reuse or rebuild specific components.
20 </p>
21<p>
22 The shared state class (<code class="filename">sstate.bbclass</code>)
23 is a relatively generic implementation of how to "capture" a snapshot of a given task.
24 The idea is that the build process does not care about the source of a task's output.
25 Output could be freshly built or it could be downloaded and unpacked from
26 somewhere - the build process doesn't need to worry about its source.
27 </p>
28<p>
29 There are two types of output, one is just about creating a directory
30 in <code class="filename">WORKDIR</code>.
31 A good example is the output of either <code class="filename">do_install</code> or
32 <code class="filename">do_package</code>.
33 The other type of output occurs when a set of data is merged into a shared directory
34 tree such as the sysroot.
35 </p>
36<p>
37 The Yocto Project team has tried to keep the details of the implementation hidden in
38 <code class="filename">sstate.bbclass</code>.
39 From a user's perspective, adding shared state wrapping to a task
40 is as simple as this <code class="filename">do_deploy</code> example taken from
41 <code class="filename">do_deploy.bbclass</code>:
42 </p>
43<pre class="literallayout">
44 DEPLOYDIR = "${WORKDIR}/deploy-${PN}"
45 SSTATETASKS += "do_deploy"
46 do_deploy[sstate-name] = "deploy"
47 do_deploy[sstate-inputdirs] = "${DEPLOYDIR}"
48 do_deploy[sstate-outputdirs] = "${DEPLOY_DIR_IMAGE}"
49
50 python do_deploy_setscene () {
51 sstate_setscene(d)
52 }
53 addtask do_deploy_setscene
54 </pre>
55<p>
56 In the example, we add some extra flags to the task, a name field ("deploy"), an
57 input directory where the task sends data, and the output
58 directory where the data from the task should eventually be copied.
59 We also add a <code class="filename">_setscene</code> variant of the task and add the task
60 name to the <code class="filename">SSTATETASKS</code> list.
61 </p>
62<p>
63 If you have a directory whose contents you need to preserve, you can do this with
64 a line like the following:
65 </p>
66<pre class="literallayout">
67 do_package[sstate-plaindirs] = "${PKGD} ${PKGDEST}"
68 </pre>
69<p>
70 This method, as well as the following example, also works for multiple directories.
71 </p>
72<pre class="literallayout">
73 do_package[sstate-inputdirs] = "${PKGDESTWORK} ${SHLIBSWORKDIR}"
74 do_package[sstate-outputdirs] = "${PKGDATA_DIR} ${SHLIBSDIR}"
75 do_package[sstate-lockfile] = "${PACKAGELOCK}"
76 </pre>
77<p>
78 These methods also include the ability to take a lockfile when manipulating
79 shared state directory structures since some cases are sensitive to file
80 additions or removals.
81 </p>
82<p>
83 Behind the scenes, the shared state code works by looking in
84 <a class="link" href="ref-variables-glos.html#var-SSTATE_DIR" title="SSTATE_DIR"><code class="filename">SSTATE_DIR</code></a> and
85 <a class="link" href="ref-variables-glos.html#var-SSTATE_MIRRORS" title="SSTATE_MIRRORS"><code class="filename">SSTATE_MIRRORS</code></a>
86 for shared state files.
87 Here is an example:
88 </p>
89<pre class="literallayout">
90 SSTATE_MIRRORS ?= "\
91 file://.* http://someserver.tld/share/sstate/PATH \n \
92 file://.* file:///some/local/dir/sstate/PATH"
93 </pre>
94<p>
95 </p>
96<div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;">
97<h3 class="title">Note</h3>
98 The shared state directory (<code class="filename">SSTATE_DIR</code>) is
99 organized into two-character subdirectories, where the subdirectory
100 names are based on the first two characters of the hash.
101 If the shared state directory structure for a mirror has the
102 same structure as <code class="filename">SSTATE_DIR</code>, you must
103 specify "PATH" as part of the URI to enable the build system
104 to map to the appropriate subdirectory.
105 </div>
106<p>
107 </p>
108<p>
109 The shared state package validity can be detected just by looking at the
110 filename since the filename contains the task checksum (or signature) as
111 described earlier in this section.
112 If a valid shared state package is found, the build process downloads it
113 and uses it to accelerate the task.
114 </p>
115<p>
116 The build processes uses the <code class="filename">*_setscene</code> tasks
117 for the task acceleration phase.
118 BitBake goes through this phase before the main execution code and tries
119 to accelerate any tasks for which it can find shared state packages.
120 If a shared state package for a task is available, the shared state
121 package is used.
122 This means the task and any tasks on which it is dependent are not
123 executed.
124 </p>
125<p>
126 As a real world example, the aim is when building an IPK-based image,
127 only the <code class="filename">do_package_write_ipk</code> tasks would have their
128 shared state packages fetched and extracted.
129 Since the sysroot is not used, it would never get extracted.
130 This is another reason why a task-based approach is preferred over a
131 recipe-based approach, which would have to install the output from every task.
132 </p>

17 This directory receives complete filesystem images.
18 If you want to flash the resulting image from a build onto a device, look here for the image.
19 </p>
20<p>
21 Be careful when deleting files in this directory.
22 You can safely delete old images from this directory (e.g.
23 <code class="filename">core-image-*</code>, <code class="filename">hob-image-*</code>,
24 etc.).
25 However, the kernel (<code class="filename">*zImage*</code>, <code class="filename">*uImage*</code>, etc.),
26 bootloader and other supplementary files might be deployed here prior to building an
27 image.
28 Because these files, however, are not directly produced from the image, if you
29 delete them they will not be automatically re-created when you build the image again.
30 </p>
31<p>
32 If you do accidentally delete files here, you will need to force them to be
33 re-created.
34 In order to do that, you will need to know the target that produced them.
35 For example, these commands rebuild and re-create the kernel files:
36 </p>
37<pre class="literallayout">
38 $ bitbake -c clean virtual/kernel
39 $ bitbake virtual/kernel
40 </pre>

17 This directory contains architecture-specific work sub-directories for packages built by BitBake.
18 All tasks execute from a work directory.
19 For example, the source for a particular package is unpacked, patched, configured and compiled all
20 within its own work directory.
21 Within the work directory, organization is based on the package group for which the source
22 is being compiled.
23 </p>
24<p>
25 It is worth considering the structure of a typical work directory.
26 As an example, consider the <code class="filename">linux-yocto-kernel-3.0</code>
27 on the machine <code class="filename">qemux86</code>
28 built within the Yocto Project.
29 For this package, a work directory of
30 <code class="filename">tmp/work/qemux86-poky-linux/linux-yocto-3.0+git1+&lt;.....&gt;</code>,
31 referred to as <code class="filename"><a class="link" href="ref-variables-glos.html#var-WORKDIR" title="WORKDIR">WORKDIR</a></code>, is created.
32 Within this directory, the source is unpacked to
33 <code class="filename">linux-qemux86-standard-build</code> and then patched by Quilt
34 (see the
35 "<a class="link" href="../dev-manual/using-a-quilt-workflow.html" target="_self">Modifying Package
36 Source Code with Quilt</a>" section in the Yocto Project Development Manual.
37 Within the <code class="filename">linux-qemux86-standard-build</code> directory,
38 standard Quilt directories <code class="filename">linux-3.0/patches</code>
39 and <code class="filename">linux-3.0/.pc</code> are created,
40 and standard Quilt commands can be used.
41 </p>
42<p>
43 There are other directories generated within WORKDIR.
44 The most important directory is WORKDIR<code class="filename">/temp/</code>, which has log files for each
45 task (<code class="filename">log.do_*.pid</code>) and contains the scripts BitBake runs for
46 each task (<code class="filename">run.do_*.pid</code>).
47 The WORKDIR<code class="filename">/image/</code> directory is where "make
48 install" places its output that is then split into sub-packages
49 within WORKDIR<code class="filename">/packages-split/</code>.

17 This directory receives all the OpenEmbedded build system's output.
18 BitBake creates this directory if it does not exist.
19 As a last resort, to clean up a build and start it from scratch (other than the downloads),
20 you can remove everything in the <code class="filename">tmp</code> directory or get rid of the
21 directory completely.
22 If you do, you should also completely remove the <code class="filename">build/sstate-cache</code>
23 directory as well.

17 The <a class="ulink" href="source-directory" target="_self">Source Directory</a>
18 includes a copy of BitBake for ease of use.
19 The copy usually matches the current stable BitBake release from the BitBake project.
20 BitBake, a metadata interpreter, reads the Yocto Project metadata and runs the tasks
21 defined by that data.
22 Failures are usually from the metadata and not from BitBake itself.
23 Consequently, most users do not need to worry about BitBake.
24 </p>
25<p>
26 When you run the <code class="filename">bitbake</code> command, the wrapper script in
27 <code class="filename">scripts/</code> is executed to run the main BitBake executable,
28 which resides in the <code class="filename">bitbake/bin/</code> directory.
29 Sourcing the <a class="link" href="structure-core-script.html" title="5.1.10. oe-init-build-env">oe-init-build-env</a>
30 script places the <code class="filename">scripts</code> and <code class="filename">bitbake/bin</code>
31 directories (in that order) into the shell's <code class="filename">PATH</code> environment
32 variable.

17 This script sets up the OpenEmbedded build environment.
18 Running this script with the <code class="filename">source</code> command in
19 a shell makes changes to <code class="filename">PATH</code> and sets other core BitBake variables based on the
20 current working directory.
21 You need to run this script before running BitBake commands.
22 The script uses other scripts within the <code class="filename">scripts</code> directory to do
23 the bulk of the work.
24 </p>
25<p>
26 By default, running this script without a Build Directory argument creates the
27 <code class="filename">build</code> directory.
28 If you provide a Build Directory argument when you <code class="filename">source</code>
29 the script, you direct OpenEmbedded build system to create a
30 <a class="link" href="../dev-manual/build-directory.html" target="_self">Build Directory</a> of your choice.
31 For example, the following command creates a Build Directory named
32 <code class="filename">mybuilds</code> that is outside of the
33 <a class="link" href="../dev-manual/source-directory.html" target="_self">Source Directory</a>:
34 </p>
35<pre class="literallayout">
36 $ source oe-init-build-env ~/mybuilds
37 </pre>
38<p>
39 </p>
40<div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;">
41<h3 class="title">Note</h3>
42 The OpenEmbedded build system does not support file or directory names that
43 contain spaces.
44 If you attempt to run the <code class="filename">oe-init-build-env</code> script
45 from a Source Directory that contains spaces in either the filenames
46 or directory names, the script returns an error indicating no such
47 file or directory.
48 Be sure to use a Source Directory free of names containing spaces.

18 Class files are used to abstract common code so it can be reused by multiple
19 packages.
20 Every package inherits the <code class="filename">base.bbclass</code> file.
21 Examples of other important classes are <code class="filename">autotools.bbclass</code>, which
22 in theory allows any Autotool-enabled package to work with the Yocto Project with minimal effort.
23 Another example is <code class="filename">kernel.bbclass</code> that contains common code and functions
24 for working with the Linux kernel.
25 Functions like image generation or packaging also have their specific class files
26 such as <code class="filename">image.bbclass</code>, <code class="filename">rootfs_*.bbclass</code> and
27 <code class="filename">package*.bbclass</code>.

16 As you can see, build history produces image information,
17 including dependency graphs, so you can see why something
18 was pulled into the image.
19 If you are just interested in this information and not
20 interested in collecting history or any package information,
21 you can enable writing only image information without
22 any history by adding the following
23 to your <code class="filename">conf/local.conf</code> file found in the

17 <code class="filename">LIC_FILES_CHKSUM</code> variable lists all the
18 important files that contain the license text for the source code.
19 It is possible to specify a checksum for an entire file, or a specific section of a
20 file (specified by beginning and ending line numbers with the "beginline" and "endline"
21 parameters, respectively).
22 The latter is useful for source files with a license notice header,
23 README documents, and so forth.
24 If you do not use the "beginline" parameter, then it is assumed that the text begins on the
25 first line of the file.
26 Similarly, if you do not use the "endline" parameter, it is assumed that the license text
27 ends with the last line of the file.
28 </p>
29<p>
30 The "md5" parameter stores the md5 checksum of the license text.
31 If the license text changes in any way as compared to this parameter
32 then a mismatch occurs.
33 This mismatch triggers a build failure and notifies the developer.
34 Notification allows the developer to review and address the license text changes.
35 Also note that if a mismatch occurs during the build, the correct md5
36 checksum is placed in the build log and can be easily copied to the recipe.
37 </p>
38<p>
39 There is no limit to how many files you can specify using the
40 <code class="filename">LIC_FILES_CHKSUM</code> variable.
41 Generally, however, every project requires a few specifications for license tracking.
42 Many projects have a "COPYING" file that stores the license information for all the source
43 code files.
44 This practice allows you to just track the "COPYING" file as long as it is kept up to date.
45 </p>
46<div class="tip" title="Tip" style="margin-left: 0.5in; margin-right: 0.5in;">
47<h3 class="title">Tip</h3>
48 If you specify an empty or invalid "md5" parameter, BitBake returns an md5 mis-match
49 error and displays the correct "md5" parameter value during the build.
50 The correct parameter is also captured in the build log.
51 </div>
52<div class="tip" title="Tip" style="margin-left: 0.5in; margin-right: 0.5in;">
53<h3 class="title">Tip</h3>
54 If the whole file contains only license text, you do not need to use the "beginline" and
55 "endline" parameters.

15<p>
16 BitBake is the tool at the heart of the OpenEmbedded build system and is responsible
17 for parsing the metadata, generating a list of tasks from it,
18 and then executing those tasks.
19 To see a list of the options BitBake supports, use the following help command:
20 </p>
21<pre class="literallayout">
22 $ bitbake --help
23 </pre>
24<p>
25 </p>
26<p>
27 The most common usage for BitBake is <code class="filename">bitbake &lt;packagename&gt;</code>, where
28 <code class="filename">packagename</code> is the name of the package you want to build
29 (referred to as the "target" in this manual).
30 The target often equates to the first part of a <code class="filename">.bb</code> filename.
31 So, to run the <code class="filename">matchbox-desktop_1.2.3.bb</code> file, you
32 might type the following:
33 </p>
34<pre class="literallayout">
35 $ bitbake matchbox-desktop
36 </pre>
37<p>
38 Several different versions of <code class="filename">matchbox-desktop</code> might exist.
39 BitBake chooses the one selected by the distribution configuration.
40 You can get more details about how BitBake chooses between different
41 target versions and providers in the
42 "<a class="link" href="ref-bitbake-providers.html" title="6.2. Preferences and Providers">Preferences and Providers</a>" section.
43 </p>
44<p>
45 BitBake also tries to execute any dependent tasks first.
46 So for example, before building <code class="filename">matchbox-desktop</code>, BitBake
47 would build a cross compiler and <code class="filename">eglibc</code> if they had not already
48 been built.
49 </p>
50<div class="note" title="Note" style="margin-left: 0.5in; margin-right: 0.5in;">
51<h3 class="title">Note</h3>This release of the Yocto Project does not support the <code class="filename">glibc</code>
52 GNU version of the Unix standard C library. By default, the OpenEmbedded build system
53 builds with <code class="filename">eglibc</code>.</div>
54<p>
55 </p>
56<p>
57 A useful BitBake option to consider is the <code class="filename">-k</code> or
58 <code class="filename">--continue</code> option.
59 This option instructs BitBake to try and continue processing the job as much
60 as possible even after encountering an error.
61 When an error occurs, the target that
62 failed and those that depend on it cannot be remade.
63 However, when you use this option other dependencies can still be processed.

18 An example is the Autotools class, which contains

16 The <code class="filename">.bb</code> files are usually referred to as "recipes."
17 In general, a recipe contains information about a single piece of software.
18 The information includes the location from which to download the source patches
19 (if any are needed), which special configuration options to apply,
20 how to compile the source files, and how to package the compiled output.
21 </p>
22<p>
23 The term "package" can also be used to describe recipes.
24 However, since the same word is used for the packaged output from the OpenEmbedded
25 build system (i.e. <code class="filename">.ipk</code> or <code class="filename">.deb</code> files),
26 this document avoids using the term "package" when referring to recipes.

16 You can see debug output from BitBake by using the <code class="filename">-D</code> option.
17 The debug output gives more information about what BitBake
18 is doing and the reason behind it.
19 Each <code class="filename">-D</code> option you use increases the logging level.
20 The most common usage is <code class="filename">-DDD</code>.
21 </p>
22<p>
23 The output from <code class="filename">bitbake -DDD -v targetname</code> can reveal why
24 BitBake chose a certain version of a package or why BitBake
25 picked a certain provider.
26 This command could also help you in a situation where you think BitBake did something
27 unexpected.

16 If you really want to build a specific <code class="filename">.bb</code> file, you can use
17 the command form <code class="filename">bitbake -b &lt;somepath/somefile.bb&gt;</code>.
18 This command form does not check for dependencies so you should use it
19 only when you know its dependencies already exist.
20 You can also specify fragments of the filename.
21 In this case, BitBake checks for a unique match.

16 Sometimes it can be hard to see why BitBake wants to build some other packages before a given
17 package you have specified.
18 The <code class="filename">bitbake -g targetname</code> command creates the
19 <code class="filename">depends.dot</code>, <code class="filename">package-depends.dot</code>,
20 and <code class="filename">task-depends.dot</code> files in the current directory.
21 These files show the package and task dependencies and are useful for debugging problems.
22 You can use the <code class="filename">bitbake -g -u depexp targetname</code> command to
23 display the results in a more human-readable form.

19<li class="listitem"><p>When adding new packages, it is worth watching for
20 undesirable items making their way into compiler command lines.
21 For example, you do not want references to local system files like

24<li class="listitem"><p>If you want to remove the psplash boot splashscreen,
25 add <code class="filename">psplash=false</code> to the kernel command line.
26 Doing so prevents psplash from loading and thus allows you to see the console.
27 It is also possible to switch out of the splashscreen by
28 switching the virtual console (e.g. Fn+Left or Fn+Right on a Zaurus).

15<p>The log file for shell tasks is available in
16 <code class="filename">${WORKDIR}/temp/log.do_taskname.pid</code>.
17 For example, the <code class="filename">compile</code> task for the QEMU minimal image for the x86
18 machine (<code class="filename">qemux86</code>) might be
19 <code class="filename">tmp/work/qemux86-poky-linux/core-image-minimal-1.0-r0/temp/log.do_compile.20830</code>.
20 To see what BitBake runs to generate that log, look at the corresponding
21 <code class="filename">run.do_taskname.pid</code> file located in the same directory.
22 </p>
23<p>
24 Presently, the output from Python tasks is sent directly to the console.

15<p>
16 Any given package consists of a set of tasks.
17 The standard BitBake behavior in most cases is: <code class="filename">fetch</code>,
18 <code class="filename">unpack</code>,
19 <code class="filename">patch</code>, <code class="filename">configure</code>,
20 <code class="filename">compile</code>, <code class="filename">install</code>, <code class="filename">package</code>,
21 <code class="filename">package_write</code>, and <code class="filename">build</code>.
22 The default task is <code class="filename">build</code> and any tasks on which it depends
23 build first.
24 Some tasks exist, such as <code class="filename">devshell</code>, that are not part of the
25 default build chain.
26 If you wish to run a task that is not part of the default build chain, you can use the
27 <code class="filename">-c</code> option in BitBake as follows:
28 </p>
29<pre class="literallayout">
30 $ bitbake matchbox-desktop -c devshell
31 </pre>
32<p>
33 </p>
34<p>
35 If you wish to rerun a task, use the <code class="filename">-f</code> force option.
36 For example, the following sequence forces recompilation after changing files in the
37 working directory.
38 </p>
39<pre class="literallayout">
40 $ bitbake matchbox-desktop
41 .
42 .
43 [make some changes to the source code in the working directory]
44 .
45 .
46 $ bitbake matchbox-desktop -c compile -f
47 $ bitbake matchbox-desktop
48 </pre>
49<p>
50 </p>
51<p>
52 This sequence first builds <code class="filename">matchbox-desktop</code> and then recompiles it.
53 The last command reruns all tasks (basically the packaging tasks) after the compile.
54 BitBake recognizes that the <code class="filename">compile</code> task was rerun and therefore
55 understands that the other tasks also need to be run again.
56 </p>
57<p>
58 You can view a list of tasks in a given package by running the
59 <code class="filename">listtasks</code> task as follows:
60 </p>
61<pre class="literallayout">
62 $ bitbake matchbox-desktop -c listtasks
63 </pre>
64<p>
65 The results are in the file <code class="filename">${WORKDIR}/temp/log.do_listtasks</code>.

16 The exact method for debugging build failures depends on the nature of the
17 problem and on the system's area from which the bug originates.
18 Standard debugging practices such as comparison against the last
19 known working version with examination of the changes and the re-application of steps
20 to identify the one causing the problem are
21 valid for the Yocto Project just as they are for any other system.
22 Even though it is impossible to detail every possible potential failure,
23 this section provides some general tips to aid in debugging.

16 Once an image has been built, it often needs to be installed.
17 The images and kernels built by the OpenEmbedded build system are placed in the
18 <a class="link" href="../dev-manual/build-directory.html" target="_self">Build Directory</a> in
19 <code class="filename">tmp/deploy/images</code>.
20 For information on how to run pre-built images such as <code class="filename">qemux86</code>

15<p>
16 The <code class="filename">LIC_FILES_CHKSUM</code>
17 variable contains checksums of the license text in the source code for the recipe.
18 Following is an example of how to specify <code class="filename">LIC_FILES_CHKSUM</code>:
19 </p>
20<pre class="literallayout">
21 LIC_FILES_CHKSUM = "file://COPYING;md5=xxxx \
22 file://licfile1.txt;beginline=5;endline=29;md5=yyyy \
23 file://licfile2.txt;endline=50;md5=zzzz \
24 ..."
25 </pre>
26<p>
27 </p>
28<p>
29 The build system uses the
30 <code class="filename"><a class="link" href="ref-variables-glos.html#var-S" title="S">S</a></code> variable as the
31 default directory used when searching files listed in
32 <code class="filename">LIC_FILES_CHKSUM</code>.
33 The previous example employs the default directory.
34 </p>
35<p>
36 You can also use relative paths as shown in the following example:
37 </p>
38<pre class="literallayout">
39 LIC_FILES_CHKSUM = "file://src/ls.c;startline=5;endline=16;\
40 md5=bb14ed3c4cda583abc85401304b5cd4e"
41 LIC_FILES_CHKSUM = "file://../license.html;md5=5c94767cedb5d6987c902ac850ded2c6"
42 </pre>
43<p>
44 </p>
45<p>
46 In this example, the first line locates a file in
47 <code class="filename">${S}/src/ls.c</code>.
48 The second line refers to a file in
49 <code class="filename"><a class="link" href="ref-variables-glos.html#var-WORKDIR" title="WORKDIR">WORKDIR</a></code>, which is the parent
50 of <code class="filename"><a class="link" href="ref-variables-glos.html#var-S" title="S">S</a></code>.
51 </p>
52<p>
53 Note that this variable is mandatory for all recipes, unless the
54 <code class="filename">LICENSE</code> variable is set to "CLOSED".

16 x32 is a new processor-specific Application Binary Interface (psABI) for x86_64.
17 An ABI defines the calling conventions between functions in a processing environment.
18 The interface determines what registers are used and what the sizes are for various C data types.
19 </p>
20<p>
21 Some processing environments prefer using 32-bit applications even when running
22 on Intel 64-bit platforms.
23 Consider the i386 psABI, which is a very old 32-bit ABI for Intel 64-bit platforms.
24 The i386 psABI does not provide efficient use and access of the Intel 64-bit processor resources,
25 leaving the system underutilized.
26 Now consider the x86_64 psABI.
27 This ABI is newer and uses 64-bits for data sizes and program pointers.
28 The extra bits increase the footprint size of the programs, libraries,
29 and also increases the memory and file system size requirements.
30 Executing under the x32 psABI enables user programs to utilize CPU and system resources
31 more efficiently while keeping the memory footprint of the applications low.
32 Extra bits are used for registers but not for addressing mechanisms.
