With clang 18, optee-os no longer compiles cleanly. It is now seeing:

Issues are also seen on optee-examples and optee-test.
Forcing GCC for all optee recipes until this issue can be resolved.

Introduction
This repository contains the Arm layers for OpenEmbedded.
-
meta-arm
This layer contains general recipes for the Arm architecture, such as firmware, FVPs, and Arm-specific integration.
-
meta-arm-bsp
This layer contains machines for Arm reference platforms, for example FVP Base, N1SDP, and Juno.
-
meta-arm-toolchain
This layer contains recipes for Arm's binary toolchains (GCC and Clang for -A and -M), and a recipe to build Arm's GCC.
Other Directories
-
ci
This directory contains gitlab continuous integration configuration files (KAS yaml files) as well as scripts needed for this
-
kas
This directory contains KAS yaml files to describe builds for systems not used in CI
-
scripts
This directory contains scripts used in running the CI tests
Mailing List
To interact with the meta-arm developer community, please email the meta-arm mailing list at meta-arm@lists.yoctoproject.org Currently, it is configured to only allow emails to members from those subscribed. To subscribe to the meta-arm mailing list, please go to https://lists.yoctoproject.org/g/meta-arm
Contributing
Currently, we only accept patches from the meta-arm mailing list. For general information on how to submit a patch, please read https://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded
E-mail meta-arm@lists.yoctoproject.org with patches created using this process. You can configure git-send-email to automatically use this address for the meta-arm repository with the following git command:
$ git config --local --add sendemail.to meta-arm@lists.yoctoproject.org
Commits and patches added should follow the OpenEmbedded patch guidelines:
https://www.openembedded.org/wiki/Commit_Patch_Message_Guidelines
The component being changed in the shortlog should be prefixed with the layer name (without the meta- prefix), for example:
arm-bsp/trusted-firmware-a: decrease frobbing level
arm-toolchain/gcc: enable foobar v2
Releases and Release Schedule
