12 This manual provides reference information for the current release of the Yocto Project.
13 The Yocto Project is an open-source collaboration project focused on embedded Linux
14 developers.
15 Amongst other things, the Yocto Project uses the OpenEmbedded build system, which
16 is based on the Poky project, to construct complete Linux images.
17 You can find complete introductory and getting started information on the Yocto Project
18 by reading the
19 <ulink url='&YOCTO_DOCS_QS_URL;'>Yocto Project Quick Start</ulink>.
20 For task-based information using the Yocto Project, see the
21 <ulink url='&YOCTO_DOCS_DEV_URL;'>Yocto Project Development Manual</ulink>
22 and the <ulink url='&YOCTO_DOCS_KERNEL_DEV_URL;'>Yocto Project Linux Kernel Development Manual</ulink>.
23 For Board Support Package (BSP) structure information, see the
24 <ulink url='&YOCTO_DOCS_BSP_URL;'>Yocto Project Board Support Package (BSP) Developer's Guide</ulink>.
25 You can find information on tracing and profiling in the
26 <ulink url='&YOCTO_DOCS_PROF_URL;#profile-manual'>Yocto Project Profiling and Tracing Manual</ulink>.
27 For information on BitBake, which is the task execution tool the
28 OpenEmbedded build system is based on, see the
29 <ulink url='&YOCTO_DOCS_BB_URL;#bitbake-user-manual'>BitBake User Manual</ulink>.
30 Finally, you can also find lots of Yocto Project information on the

122 <para>
123 Yocto Project releases are tested against the stable Linux
124 distributions in the following list.

128
129 <para>
130 In particular, the Yocto Project does not support
131 and currently has no plans to support
132 rolling-releases or development distributions due to their
133 constantly changing nature.
134 We welcome patches and bug reports, but keep in mind that
135 our priority is on the supported platforms listed below.

175 <note>
176 While the Yocto Project Team attempts to ensure all Yocto Project
177 releases are one hundred percent compatible with each officially
178 supported Linux distribution, instances might exist where you
179 encounter a problem while using the Yocto Project on a specific
180 distribution.
181 For example, the CentOS 6.4 distribution does not include the
182 Gtk+ 2.20.0 and PyGtk 2.21.0 (or higher) packages, which are
183 required to run
184 <ulink url='&YOCTO_HOME_URL;/tools-resources/projects/hob'>Hob</ulink>.

355 In order to use the build system, your host development system
356 must meet the following version requirements for Git, tar, and
357 Python:
358 <itemizedlist>
359 <listitem><para>Git 1.7.5 or greater</para></listitem>

366 <para>
367 If your host development system does not meet all these requirements,
368 you can resolve this by installing a <filename>buildtools</filename>
369 tarball that contains these tools.
370 You can get the tarball one of two ways: download a pre-built
371 tarball or use BitBake to build the tarball.

379 the easiest of the two methods by which you can get these tools:
380 <orderedlist>
381 <listitem><para>
382 Locate and download the <filename>*.sh</filename> at

385 <listitem><para>
386 Execute the installation script.

389 $ sh poky-eglibc-x86_64-buildtools-tarball-x86_64-buildtools-nativesdk-standalone-&DISTRO;.sh
390 </literallayout>
391 During execution, a prompt appears that allows you to
392 choose the installation directory.
393 For example, you could choose the following:
394 <literallayout class='monospaced'>
395 /home/your-username/buildtools
396 </literallayout>
397 </para></listitem>
398 <listitem><para>

402 $ source /home/your-username/buildtools/environment-setup-i586-poky-linux
403 </literallayout>
404 Of course, you need to supply your installation directory and be
405 sure to use the right file (i.e. i585 or x86-64).
406 </para>
407 <para>
408 After you have sourced the setup script,
409 the tools are added to <filename>PATH</filename>

424 only when you have a build host that can already run BitBake.
425 In this case, you use that machine to build the

456 Once the build completes, you can find the

458 the tools in the <filename>tmp/deploy/sdk</filename>
459 subdirectory of the
460 <ulink url='&YOCTO_DOCS_DEV_URL;#build-directory'>Build Directory</ulink>.

547 Development using the Yocto Project requires a local
548 <ulink url='&YOCTO_DOCS_DEV_URL;#source-directory'>Source Directory</ulink>.
549 You can set up the Source Directory by cloning a copy of the upstream
550 <ulink url='&YOCTO_DOCS_DEV_URL;#poky'>poky</ulink> Git repository.
551 For information on how to do this, see the
552 "<ulink url='&YOCTO_DOCS_DEV_URL;#getting-setup'>Getting Set Up</ulink>"
