It's not currently possible to set the build tree to be somewhere we control, but we know it will always be in the build directory alongside the setup.py so we can [cleandirs] that. MJ: helps with build/lib directory being added when a recipe is rebuilt in the same WORKDIR multiple times, e.g.: Just rebuilding python3-tqdm in the same TMPDIR after cherry-picking this: $ buildhistory-diff -p buildhistory build-minus-1 | grep PKGSIZE python3-google-auth/python3-google-auth: PKGSIZE changed from 11752510 to 1315694 (-89%) python3-googleapis-common-protos/python3-googleapis-common-protos: PKGSIZE changed from 7108856 to 794024 (-89%) $ wc -l python3-google-auth/2.29.0*/image/usr/lib/python3.12/site-packages/google_auth-2.29.0.dist-info/RECORD 554 python3-google-auth/2.29.0-old/image/usr/lib/python3.12/site-packages/google_auth-2.29.0.dist-info/RECORD 66 python3-google-auth/2.29.0/image/usr/lib/python3.12/site-packages/google_auth-2.29.0.dist-info/RECORD $ wc -l python3-googleapis-common-protos/1.63.0*/image/usr/lib/python3.12/site-packages/googleapis_common_protos-1.63.0.dist-info/RECORD 1166 python3-googleapis-common-protos/1.63.0-old/image/usr/lib/python3.12/site-packages/googleapis_common_protos-1.63.0.dist-info/RECORD 134 python3-googleapis-common-protos/1.63.0/image/usr/lib/python3.12/site-packages/googleapis_common_protos-1.63.0.dist-info/RECORD (From OE-Core rev: a0151ab56cf3fcaa6587e240b5454fed5315a534) Signed-off-by: Ross Burton <ross.burton@arm.com> Signed-off-by: Mathieu Dubois-Briand <mathieu.dubois-briand@bootlin.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org> Signed-off-by: Martin Jansa <martin.jansa@gmail.com> (cherry picked from commit f3854f4f60801e3b6788bee3a0a1850fc498d536) Signed-off-by: Yoann Congal <yoann.congal@smile.fr> Signed-off-by: Paul Barker <paul@pbarker.dev>
Poky
Poky is an integration of various components to form a pre-packaged build system and development environment which is used as a development and validation tool by the Yocto Project. It features support for building customised embedded style device images and custom containers. There are reference demo images ranging from X11/GTK+ to Weston, commandline and more. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK suitable for IDE integration.
Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of BSP layers which extend the systems capabilities in a modular way. Many layers are available and can be found through the layer index.
As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation, the 'meta-yocto' layer which has configuration and hardware support components. These components are all part of the Yocto Project and OpenEmbedded ecosystems.
The Yocto Project has extensive documentation about the system including a reference manual which can be found at https://docs.yoctoproject.org/
OpenEmbedded is the build architecture used by Poky and the Yocto project. For information about OpenEmbedded, see the OpenEmbedded website.

Where to Send Patches
As Poky is an integration repository (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:
OpenEmbedded-Core (files in meta/, meta-selftest/, meta-skeleton/, scripts/):
- Git repository: https://git.openembedded.org/openembedded-core/
- Mailing list: openembedded-core@lists.openembedded.org
BitBake (files in bitbake/):
- Git repository: https://git.openembedded.org/bitbake/
- Mailing list: bitbake-devel@lists.openembedded.org
Documentation (files in documentation/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
- Mailing list: docs@lists.yoctoproject.org
meta-yocto (files in meta-poky/, meta-yocto-bsp/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto
- Mailing list: poky@lists.yoctoproject.org
If in doubt, check the openembedded-core git repository for the content you intend to modify as most files are from there unless clearly one of the above categories. Before sending, be sure the patches apply cleanly to the current git repository branch in question.
