Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

@conda-forge/llvmdev, this should be ready, PTAL!

The main changes are:

• SOVER now contains minor, see llvm/llvm-project@91a3846 resp. the related RFC
• remove libLLVM-<major>.${SHEXT} (as it's pointing to plain libllvm.so which is in a different output for us)

[h-vetinari]

@conda-forge/llvmdev this is green now; 18.1.0 had a bug that got fixed in 18.1.1. PTAL :)

@isuruf
Any objection to removing $PREFIX/lib/libLLVM-{{ major_ver }}${SHLIB_EXT} in the context of llvm/llvm-project@91a3846?

[isuruf]

I don't understand? Why are we removing a symlink that the project is adding?

[h-vetinari]

The referenced commit explains:

The main library now has a more convential library name: libLLVM.so.$major.$minor. The old library name: libLLVM-$major.so is now a symlink that points to the new library.

So for one, libLLVM-$major.so is considered "the old library name" - which in itself wouldn't be an issue for shipping it - but secondly, libLLVM-$major.so is now a symlink that points to libLLVM.so, which breaks our output-layering (as the latter is not part of libllvm18, and so the symlink appears dead and test -f ... fails).

Seeing that there's now a "new" library name, I didn't think it's necessary to fix this, but if you want to retain the old name, we can point libLLVM-$major.so to libLLVM.so.$major.$minor.

[h-vetinari]

It's perhaps worth mentioning that I've built a functional LLVM stack for rc4 without that symlink, which is also why I don't think that we really need it.

[h-vetinari]

Ah, just saw that this was fixed in llvm/llvm-project@10c48a7 in the meantime. It's also on the 18.x branch already (llvm/llvm-project@4cc7a75), but while the github UI doesn't show it as released in a tag, it's actually part of 18.1.1.

[xhochy]

If I understand the comments here correctly that the discussion you hab is resolved by upstream in the latest release and we could merge if CI passes?

[h-vetinari]

That's the plan yes :)
