766 script, and support files from the appropriate directory under
767 <ulink url='&YOCTO_TOOLCHAIN_DL_URL;'></ulink>.
768 Toolchains are available for 32-bit and 64-bit x86 development
769 systems from the <filename>i686</filename> and
770 <filename>x86_64</filename> directories, respectively.
771 The toolchains the Yocto Project provides are based off the
772 <filename>core-image-sato</filename> image and contain
773 libraries appropriate for developing against that image.
774 Each type of development system supports five or more target
775 architectures.

777
778 <para>
779 The names of the tarball installer scripts are such that a

782 representing the target architecture.

827 The following command shows how to run the installer given a toolchain tarball

896 <para>
897 The filesystem image has two tarball forms: <filename>ext3</filename> and

899 You must use the <filename>ext3</filename> form when booting an image using the

901 The <filename>tar</filename> form can be flattened out in your host development system
902 and used for build purposes with the Yocto Project.

924 Before you start the QEMU emulator, you need to set up the emulation environment.

931 i586, x86_64, ppc603e, mips, or armv5te.
932
933 <replaceable>if</replaceable> is a string representing an embedded application binary interface.
934 Not all setup scripts include this string.

946
947 <replaceable>kernel-image</replaceable> is the architecture-specific kernel image.

951 </literallayout>
952 </para>
953
954 <para>
955 Continuing with the example, the following two commands setup the emulation
956 environment and launch QEMU.
957 This example assumes the root filesystem (<filename>.ext3</filename> file) and
958 the pre-built kernel image file both reside in your home directory.
959 The kernel and filesystem are for a 32-bit target architecture.

966 </para>
967
968 <para>
969 The environment in which QEMU launches varies depending on the filesystem image and on the
970 target architecture.
971 For example, if you source the environment for the ARM target
972 architecture and then boot the minimal QEMU image, the emulator comes up in a new
973 shell in command-line mode.
974 However, if you boot the SDK image, QEMU comes up with a GUI.
975 <note>Booting the PPC image results in QEMU launching in the same shell in
976 command-line mode.</note>

39 The Yocto Project is an open-source collaboration project focused on
40 embedded Linux developers.
41 Among other things, the Yocto Project uses a build system based on the
42 OpenEmbedded (OE) project, which uses the
43 <ulink url='&YOCTO_DOCS_DEV_URL;#bitbake-term'>BitBake</ulink>
44 tool, to construct complete Linux images.

54 Project using a non-Linux development system.

147 The Yocto Project can generate images for many kinds of devices.
148 However, the standard example machines target QEMU full-system emulation for x86, x86-64, ARM, MIPS,
149 and PPC-based architectures as well as specific hardware such as the
150 <trademark class='registered'>Intel</trademark> Desktop Board DH55TC.
151 Because an image developed with the Yocto Project can boot inside a QEMU emulator, the
152 development environment works nicely as a test platform for developing embedded software.

156 Another important Yocto Project feature is the Sato reference User

158 This optional UI that is based on GTK+ is intended for devices with
159 restricted screen sizes.
160 The UI sits neatly on top of a device using the
161 GTK+ stack and provides a well-defined user experience.
162 Implemented in its own layer, it makes it clear to developers how they
163 can implement their own user interface on top of a Linux image created
164 with the Yocto Project.

258 Packages and package installation vary depending on your development system
259 and on your intent.
260 For example, if you want to build an image that can run
261 on QEMU in graphical mode (a minimal, basic build
262 requirement), then the number of packages is different than if you want to
263 build an image on a headless system or build out the Yocto Project
264 documentation set.
265 Collectively, the number of required packages is large
266 if you want to be able to cover all cases.

530 <trademark class='registered'>Intel</trademark> 32-bit based architecture.

541 <ulink url='&YOCTO_DOCS_BB_URL;#var-BB_NUMBER_PARSE_THREADS'><filename>BB_NUMBER_PARSE_THREADS</filename></ulink>
542 variables.
543 By default, the OpenEmbedded build system sets these variables
544 based on the number of processor cores your build host uses.
545 Thus, you typically do not need to uncomment these variables in
546 your <filename>local.conf</filename> file to gain optimal build
547 times.
