2# This file is your local configuration file and is where all local user settings
3# are placed. The comments in this file give some guide to the options a new user
4# to the system might want to change but pretty much any configuration option can
5# be set in this file. More adventurous users can look at local.conf.extended
6# which contains other examples of configuration which can be placed in this file
7# but new users likely won't need any of them initially.
8#
9# Lines starting with the '#' character are commented out and in some cases the
10# default values are provided as comments to show people example syntax. Enabling
11# the option is a question of removing the # character and making any change to the
12# variable as required.

14#
15# Machine Selection
16#
17# You need to select a specific machine to target the build with. There are a selection
18# of emulated machines available which can boot and run in the QEMU emulator:
19#
20#MACHINE ?= "qemuarm"
21#MACHINE ?= "qemumips"
22#MACHINE ?= "qemuppc"
23#MACHINE ?= "qemux86"
24#MACHINE ?= "qemux86-64"
25#
26# There are also the following hardware board target machines included for
27# demonstration purposes:
28#
29#MACHINE ?= "beaglebone"
30#MACHINE ?= "genericx86"
31#MACHINE ?= "genericx86-64"
32#MACHINE ?= "mpc8315e-rdb"
33#MACHINE ?= "edgerouter"
34#
35# This sets the default machine to be qemux86 if no other machine is selected:
36MACHINE ??= "qemux86"
37
38#
39# Where to place downloads
40#
41# During a first build the system will download many different source code tarballs
42# from various upstream projects. This can take a while, particularly if your network
43# connection is slow. These are all stored in DL_DIR. When wiping and rebuilding you
44# can preserve this directory to speed up this part of subsequent builds. This directory
45# is safe to share between multiple builds on the same machine too.
46#
47# The default is a downloads directory under TOPDIR which is the build directory.
48#
49#DL_DIR ?= "${TOPDIR}/downloads"
50
51#
52# Where to place shared-state files
53#
54# BitBake has the capability to accelerate builds based on previously built output.
55# This is done using "shared state" files which can be thought of as cache objects
56# and this option determines where those files are placed.
57#
58# You can wipe out TMPDIR leaving this directory intact and the build would regenerate
59# from these files if no changes were made to the configuration. If changes were made
60# to the configuration, only shared state files where the state was still valid would
61# be used (done using checksums).
62#
63# The default is a sstate-cache directory under TOPDIR.
64#
65#SSTATE_DIR ?= "${TOPDIR}/sstate-cache"
66
67#
68# Where to place the build output
69#
70# This option specifies where the bulk of the building work should be done and
71# where BitBake should place its temporary files and output. Keep in mind that
72# this includes the extraction and compilation of many applications and the toolchain
73# which can use Gigabytes of hard disk space.
74#
75# The default is a tmp directory under TOPDIR.
76#
77#TMPDIR = "${TOPDIR}/tmp"
78
79#
80# Default policy config
81#
82# The distribution setting controls which policy settings are used as defaults.
83# The default value is fine for general Yocto project use, at least initially.
84# Ultimately when creating custom policy, people will likely end up subclassing
85# these defaults.
86#
87DISTRO ?= "poky"
88# As an example of a subclass there is a "bleeding" edge policy configuration
89# where many versions are set to the absolute latest code from the upstream
90# source control systems. This is just mentioned here as an example, its not
91# useful to most new users.
92# DISTRO ?= "poky-bleeding"
93
94#
95# Package Management configuration
96#
97# This variable lists which packaging formats to enable. Multiple package backends
98# can be enabled at once and the first item listed in the variable will be used
99# to generate the root filesystems.
100# Options are:
101# - 'package_deb' for debian style deb files
102# - 'package_ipk' for ipk files are used by opkg (a debian style embedded package manager)
103# - 'package_rpm' for rpm style packages
104# E.g.: PACKAGE_CLASSES ?= "package_rpm package_deb package_ipk"
105# We default to rpm:
106PACKAGE_CLASSES ?= "package_rpm"
107
108#
109# SDK/ADT target architecture
110#
111# This variable specifies the architecture to build SDK/ADT items for and means
112# you can build the SDK packages for architectures other than the machine you are
113# running the build on (i.e. building i686 packages on an x86_64 host).
114# Supported values are i686 and x86_64
115#SDKMACHINE ?= "i686"
116
117#
118# Extra image configuration defaults
119#
120# The EXTRA_IMAGE_FEATURES variable allows extra packages to be added to the generated
121# images. Some of these options are added to certain image types automatically. The
122# variable can contain the following options:
123# "dbg-pkgs" - add -dbg packages for all installed packages
124# (adds symbol information for debugging/profiling)
125# "dev-pkgs" - add -dev packages for all installed packages
126# (useful if you want to develop against libs in the image)
127# "ptest-pkgs" - add -ptest packages for all ptest-enabled packages
128# (useful if you want to run the package test suites)
129# "tools-sdk" - add development tools (gcc, make, pkgconfig etc.)
130# "tools-debug" - add debugging tools (gdb, strace)
131# "eclipse-debug" - add Eclipse remote debugging support
132# "tools-profile" - add profiling tools (oprofile, exmap, lttng, valgrind)
133# "tools-testapps" - add useful testing tools (ts_print, aplay, arecord etc.)
134# "debug-tweaks" - make an image suitable for development
135# e.g. ssh root access has a blank password
136# There are other application targets that can be used here too, see
137# meta/classes/image.bbclass and meta/classes/core-image.bbclass for more details.
138# We default to enabling the debugging tweaks.
139EXTRA_IMAGE_FEATURES = "debug-tweaks"
140
141#
142# Additional image features
143#
144# The following is a list of additional classes to use when building images which
145# enable extra features. Some available options which can be included in this variable
146# are:
147# - 'buildstats' collect build statistics
148# - 'image-mklibs' to reduce shared library files size for an image
149# - 'image-prelink' in order to prelink the filesystem image
150# - 'image-swab' to perform host system intrusion detection
151# NOTE: if listing mklibs & prelink both, then make sure mklibs is before prelink
152# NOTE: mklibs also needs to be explicitly enabled for a given image, see local.conf.extended
153USER_CLASSES ?= "buildstats image-mklibs image-prelink"
154
155#
156# Runtime testing of images
157#
158# The build system can test booting virtual machine images under qemu (an emulator)
159# after any root filesystems are created and run tests against those images. To
160# enable this uncomment this line. See classes/testimage(-auto).bbclass for
161# further details.
162#TEST_IMAGE = "1"
163#
164# Interactive shell configuration
165#
166# Under certain circumstances the system may need input from you and to do this it
167# can launch an interactive shell. It needs to do this since the build is
168# multithreaded and needs to be able to handle the case where more than one parallel
169# process may require the user's attention. The default is iterate over the available
170# terminal types to find one that works.
171#
172# Examples of the occasions this may happen are when resolving patches which cannot
173# be applied, to use the devshell or the kernel menuconfig
174#
175# Supported values are auto, gnome, xfce, rxvt, screen, konsole (KDE 3.x only), none
176# Note: currently, Konsole support only works for KDE 3.x due to the way
177# newer Konsole versions behave

183# Disk Space Monitoring during the build
184#
185# Monitor the disk space during the build. If there is less that 1GB of space or less
186# than 100K inodes in any key build location (TMPDIR, DL_DIR, SSTATE_DIR), gracefully
187# shutdown the build. If there is less that 100MB or 1K inodes, perform a hard abort
188# of the build. The reason for this is that running completely out of space can corrupt
189# files and damages the build in ways which may not be easily recoverable.

199# Shared-state files from other locations
200#
201# As mentioned above, shared state files are prebuilt cache data objects which can
202# used to accelerate build time. This variable can be used to configure the system
203# to search other mirror locations for these objects before it builds the data itself.
204#
205# This can be a filesystem directory, or a remote url such as http or ftp. These
206# would contain the sstate-cache results from previous builds (possibly from other
207# machines). This variable works like fetcher MIRRORS/PREMIRRORS and points to the
208# cache locations to check for the shared objects.
209# NOTE: if the mirror uses the same structure as SSTATE_DIR, you need to add PATH
210# at the end as shown in the examples below. This will be substituted with the
211# correct path within the directory structure.

218# Qemu configuration
219#
220# By default qemu will build with a builtin VNC server where graphical output can be
