win32_build.sh was the culprit. “ninja test” is trying to actually run the tests, so we need “ninja tests” when targeting Windows. I’ve submitted a fix: https://github.com/ceph/ceph/pull/40169 Thanks again for bringing it up!

I’ll look into it right away. Ideally, we should only skip the unsupported tests. Passing SKIP_TESTS will skip all of them. Is there an easy way for me to filter Windows job results? I’m looking at this page [1] but I can’t filter the jobs based on the platform.

Log: /mnt/ceph/build/build.log [0/560] cd /mnt/ceph/build && /usr/bin/ctest --force-new-ctest-process Test project /mnt/ceph/build ... Unable to find executable: /mnt/ceph/build/bin/unittest_base64 it seems quite a few tests were not built. can we filter out the tests not built or supported, or just set "SKIP_TESTS" in win32_build.sh? cheers,
