C compiler cannot create executables when using `CLANGARM64`

[Joseph-Edwards]

Summarry

I am adding a workflow job that compiles some C code on windows using msys2 with autotools. When I specify msystem to be MINGW64, MINGW32, UCRT64 or CLANG64 everything works fine. However, when I specify msystem to be CLANGARM64, I get an error when running ./configure which says "C compiler cannot create executables".

MRE

Inside .github/workflows/mre.yml

name: test
on: workflow_dispatch

jobs:
  msys:
    defaults:
      run:
        shell: msys2 {
    runs-on: windows-latest
    steps:
      - uses: msys2/setup-msys2@v2
        with:
          update: true
          msystem: CLANGARM64
          pacboy: toolchain autotools
      - uses: actions/checkout@v4
      - name: Configure . . .
        run: autoreconf -if && ./configure

Expected behaviour

Everything to pass, as is the case when changing CLANGARM64 to one of the other systems.

Additional info

Please see config.log for the detailed log, and this action for the place where this error occurred.

For CLANGARM64, you need to set windows-11-arm runner. See https://github.blog/changelog/2025-04-14-windows-arm64-hosted-runners-now-available-in-public-preview/

Ah yes, that's fixed it. Thank you @Biswa96! Do you think it's worth updating platform-check-severity to include a check for this? I'd be happy to open a pull request if yes.

I think it would be a good idea to include that kind of check but please wait for others to comment on this topic.
