Build failure: <cstdarg> not found on buildbot


seems that I caused a buildbot failure (sorry!) [1], because a clang-tidy test includes , which is not found on the buildbot.

The error is:
/var/lib/buildbot/slaves/hexagon-build-03/clang-hexagon-elf/llvm.obj/tools/clang/tools/extra/test/clang-tidy/Output/cppcoreguidelines-pro-type-vararg.cpp.tmp.cpp:39:10: error: ‘cstdarg’ file not found [clang-diagnostic-error]

I have a hard time investigating, because it works on my machine.
Does anyone have an idea why is it not found on the buildbot? Do I need to pass additional (include) flags inside the test?

Thanks, and sorry for the noise,



for what it’s worth, this was fixed already (by replacing it with #include <stdarg.h>, which is a builtin include)
