Unable to compile with coverage information on Windows #9

Closed bhase closed 3 weeks ago

bhase commented 1 month ago

What I did so far:

download + extract xpack-clang-18.1.8-1
add the bin/ directory to path
trying to compile with -fprofile-instr-generate -fcoverage-mapping

I expected to get an executable, but I got this error message: ld.lld: error: could not open 'C:/Projects/ele20ll-2speed-adv/Tools/Compiler/xpack-clang-18.1.8-1/lib/clang/18/lib/windows/libclang_rt.profile-x86_64.a': No such file or directory

This is correct, the file does not exist. Is there something missing in the .zip package?

I managed to reproduce the issue. I'll investigate.

ilg-ul commented 1 month ago

I reported the issue upstream:

https://github.com/mstorsjo/llvm-mingw/issues/446

ilg-ul commented 1 month ago

So the problem is not upstream, it must be something wrong with my scripts.

I'll investigate, but it might take some time.

Any news on this topic? Can I do anything to help?

ilg-ul commented 1 month ago

This week I'm not in the office, I plan to check it next week.

ilg-ul commented 3 weeks ago

I identified the reason why those libraries were missing from the windows archive.

I'll add a test case with -fprofile-instr-generate -fcoverage-mapping to the global tests, and, when everything is fine on all platforms, I'll make a 18.1.8-2 release.

Fine to hear that :-) Thank you very much

ilg-ul commented 3 weeks ago

Fixed in 18.1.8-2.
