9 Welcome to the Yocto Project Reference Manual!
10 This manual provides reference information for the current release
11 of the Yocto Project.
12 The manual is best used after you have an understanding
13 of the basics of the Yocto Project.
14 The manual is neither meant to be read as a starting point to the
15 Yocto Project nor read from start to finish.
16 Use this manual to find variable definitions, class
17 descriptions, and so forth as needed during the course of using
18 the Yocto Project.

157 While the Yocto Project Team attempts to ensure all Yocto Project
158 releases are one hundred percent compatible with each officially
159 supported Linux distribution, instances might exist where you
160 encounter a problem while using the Yocto Project on a specific

380 <para>
381 If your host development system does not meet all these requirements,
382 you can resolve this by installing a <filename>buildtools</filename>
383 tarball that contains these tools.
384 You can get the tarball one of two ways: download a pre-built
385 tarball or use BitBake to build the tarball.

402 <literallayout class='monospaced'>
403 $ sh ~/Downloads/x86_64-buildtools-nativesdk-standalone-&DISTRO;.sh
404 </literallayout>
405 During execution, a prompt appears that allows you to
406 choose the installation directory.
407 For example, you could choose the following:
408 <literallayout class='monospaced'>
409 /home/<replaceable>your-username</replaceable>/buildtools
410 </literallayout>

422 After you have sourced the setup script,

437 Building and running your own buildtools installer applies
438 only when you have a build host that can already run BitBake.
439 In this case, you use that machine to build the
440 <filename>.sh</filename> file and then
441 take steps to transfer and run it on a
442 machine that does not meet the minimal Git, tar, and Python
443 requirements.

447 Here are the steps to take to build and run your own
448 buildtools installer:
449 <orderedlist>
450 <listitem><para>
451 On the machine that is able to run BitBake,
452 be sure you have set up your build environment with
453 the setup script
454 (<link linkend='structure-core-script'><filename>&OE_INIT_FILE;</filename></link>).
455 </para></listitem>
456 <listitem><para>
457 Run the BitBake command to build the tarball:
458 <literallayout class='monospaced'>
459 $ bitbake buildtools-tarball
460 </literallayout>
461 <note>
462 The
463 <link linkend='var-SDKMACHINE'><filename>SDKMACHINE</filename></link>
464 variable in your <filename>local.conf</filename> file
465 determines whether you build tools for a 32-bit
466 or 64-bit system.
467 </note>
468 Once the build completes, you can find the
469 <filename>.sh</filename> file that installs
470 the tools in the <filename>tmp/deploy/sdk</filename>
471 subdirectory of the
472 <link linkend='build-directory'>Build Directory</link>.
473 The installer file has the string "buildtools"
474 in the name.
475 </para></listitem>
476 <listitem><para>
477 Transfer the <filename>.sh</filename> file from the
478 build host to the machine that does not meet the
479 Git, tar, or Python requirements.
480 </para></listitem>
481 <listitem><para>
482 On the machine that does not meet the requirements,
483 run the <filename>.sh</filename> file
484 to install the tools.
485 Here is an example:
486 <literallayout class='monospaced'>
487 $ sh ~/Downloads/x86_64-buildtools-nativesdk-standalone-&DISTRO;.sh
488 </literallayout>
489 During execution, a prompt appears that allows you to
490 choose the installation directory.
491 For example, you could choose the following:
492 <literallayout class='monospaced'>
493 /home/<replaceable>your_username</replaceable>/buildtools
494 </literallayout>
495 </para></listitem>
496 <listitem><para>
497 Source the tools environment setup script by using a
498 command like the following:
499 <literallayout class='monospaced'>
500 $ source /home/<replaceable>your_username</replaceable>/buildtools/environment-setup-i586-poky-linux
501 </literallayout>
502 Of course, you need to supply your installation directory and be
503 sure to use the right file (i.e. i585 or x86-64).
504 </para>
505 <para>
506 After you have sourced the setup script,
507 the tools are added to <filename>PATH</filename>
508 and any other environment variables required to run the
509 tools are initialized.
510 The results are working versions versions of Git, tar,
511 Python and <filename>chrpath</filename>.
