Currently the CMake configuration for llvm finds the python pygments and pyyaml if they are installed on the host. This makes builds non-reproducible across different machines, some having those modules installed and some others not. This has been causing a 'reproducible' failure on one of the autobuilders: AssertionError: The following deb packages are missing or different and not in exclusion list: /home/pokybuild/yocto-worker/reproducible/build/build-st/reproducibleB/tmp/deploy/deb/./core2-64/llvm-dev_14.0.4-r0_amd64.deb The following ipk packages are missing or different and not in exclusion list: /home/pokybuild/yocto-worker/reproducible/build/build-st/reproducibleB/tmp/deploy/ipk/./core2-64/llvm-dev_14.0.4-r0_core2-64.ipk The following rpm packages are missing or different and not in exclusion list: /home/pokybuild/yocto-worker/reproducible/build/build-st/reproducibleB/tmp/deploy/rpm/./core2_64/llvm-dev-14.0.4-r0.core2_64.rpm Fix by adding an explicit PACKAGECONFIG to control the LLVM_HAVE_OPT_VIEWER_MODULES option in CMake. If unset, it forces CMake to ignore pygments and pyyaml, no matter it they are available on the host. If set, it DEPENDS on the pygments and pyyaml modules so that CMake will find and use them. Based on suggestions from Stefan and Markus -- thanks.

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.
Contribution Guidelines
The project works using a mailing list patch submission process. Patches should be sent to the mailing list for the repository the components originate from (see below). Throughout the Yocto Project, the README files in the component in question should detail where to send patches, who the maintainers are and where bugs should be reported.
A guide to submitting patches to OpenEmbedded is available at:
https://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded
There is good documentation on how to write/format patches at:
https://www.openembedded.org/wiki/Commit_Patch_Message_Guidelines
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.
