Since we branched LLVM install Clang 16 and remove Clang 12. Currently our Docker installs 4 versions of Clang so our CI can use the same image for both the main and the release branch. This wasn't done for the other Clang tools so they always use the same version for testing the main and the release branch. Instead install 2 versions for the tools. However it seems the default for Clang and its tools were the latest released version instead of the ToT. To lessen the risk of breaking the release CI, version 14 is installed hard-coded as a temporary solution. Updating the main branch to use the Clang 16 compiler will be done in a separate patch.

# This Dockerfile describes the base image used to run the various libc++
|
|
# build bots. By default, the image runs the Buildkite Agent, however one
|
|
# can also just start the image with a shell to debug CI failures.
|
|
#
|
|
# To start a Buildkite Agent, run it as:
|
|
# $ docker run --env-file <secrets> -it $(docker build -q libcxx/utils/ci)
|
|
#
|
|
# The environment variables in `<secrets>` should be the ones necessary
|
|
# to run a BuildKite agent.
|
|
#
|
|
# If you're only looking to run the Docker image locally for debugging a
|
|
# build bot, see the `run-buildbot-container` script located in this directory.
|
|
#
|
|
# A pre-built version of this image is maintained on DockerHub as ldionne/libcxx-builder.
|
|
# To update the image, rebuild it and push it to ldionne/libcxx-builder (which
|
|
# will obviously only work if you have permission to do so).
