How to get coverage from clang (C++)

[drazisil-codecov]

I got Node.js' C++ coverage working again last night. For future reference, if someone is trying to use gcovr to create a coverage report for codecov, and they switch their compiler to clang from gcc at some point, you need to do this:

--gcov-executable="llvm-cov-18 gcov"

Documentation from gcovr: https://gcovr.com/en/5.1/guide/compiling.html#choosing-the-right-gcov-executable

The annoying thing is, in my case, I needed to figure out the llvm-cov version, so that I could call llvm-cov-18. This was achieved by running ls -l in /usr/bin and looking for bins matching llvm-cov.
