[Issue] Failed to build - file `llvm-ar` not found. Missing Dependency?

[ErrWare]

I was failing to install liblisa-semantics-tool [1] because xed-sys v0.5.1+xed-2023.12.19 was failing with a "FileNotFoundError: [Errno 2] No such file or directory: 'llvm-ar'".

Installing llvm with brew install llvm resolved the issue.

In that project's dependencies [2] I don't see xed-sys nor llvm, so I'm guessing the problem is xed-sys is missing a dependency.

1. https://github.com/libLISA/liblisa/tree/main/cli/liblisa-semantics-tool
2. https://github.com/libLISA/liblisa/blob/main/cli/liblisa-semantics-tool/Cargo.toml

Ultimately xed-sys shells out to mbuild to actually build xed (see https://intelxed.github.io/build-manual/). It usually makes a reasonable choice of what compiler to use but I guess in this case it's not quite right.

Unfortunately, the only thing I can really do about these kinds of dependencies is document them in the README, since they end up being implicit environmental dependencies. I will add a note to the readme about needing llvm installed on macos.

I would be interested in seeing your build logs, just so I can see the full error for future reference. But there really isn't much xed-sys can do here.

I'm happy to send my build logs, but I'm no build expert. Can you suggest a specific file to send or place to look for logs?
