mesa/llvm still depending on obsolete LLVM_COMPAT

Message

ExecutorElassus · Post by **ExecutorElassus** » Sat Jun 07, 2025 8:37 am

So, I'd very much like to do away with having clang, clang-runtime, rt-compiler, etc having slotted installs of both -19.* and -20*. The dependency appears to be media-libs/mesa, but looking at mesa's ebuild shows that it is in fact compatible with LLVM_COMPAT-20.

However, trying 'emerge -pvc clang' gives this:

Code: Select all

# emerge -pvc clang clang-runtime compiler-rt compiler-rt-sanitizers libclc clang-toolchain-symlinks

Calculating dependencies... done!

    media-libs/mesa-25.1.2 requires llvm-core/clang:19[llvm_targets_AMDGPU(+),abi_x86_32(-),abi_x86_64(-)]

In my make.conf I have only this for LLVM:

Code: Select all

LLVM_TARGETS="AMDGPU X86"

So how do I resolve this dependency to be able to remove the :19 version of all the LLVM packages?

Cheers,

You can try in

Code: Select all

llvm-core/libclc -llvm_slot_19 llvm_slot_20
media-libs/mesa -llvm_slot_19 llvm_slot_20

Code: Select all

emerge -avuDU @world
emerge -a --depclean

You should unmask a libclc version greater than 19.1.7.

It's unmasked but won't build because of the mesa dependency. I'll try Josef's suggestion and see how that works.

UPDATE: that did the trick. I've now unmerged all the LLVM-19 packages.

welp, at long last mesa has updated to be compatible with LLVM-21, and now I'm trying to remove the -20 versions. Here is what I see (I've removed dependencies for llvm-21, since those aren't relevant):

>>> No packages selected for removal by depclean

My package.use has been updated so that both mesa and libclc build for llvm-21, and I've remerged them. So why are these package refusing to depclean? As far as I can see I've included every dependent package on the list, but it still refuses. What am I doing wrong here?

Thanks for the help.

The only package that came up on the list mentioning llvm was qttools, and I remerged it. I also set `*/* LLVM_SLOT: -* 21` in package.use to set it globally. Still no luck: I still get the same list of circular dependencies. I suppose I could just hard-unmerge them and see if anything comes up.

I gotta say, I like the idea of slotted packages, except in cases like this where I'm stuck with two complete toolchains and no way to figure out why I can't remove the obsolete one. I'm sure I'm missing something; I just can't find it.

I recall another thread with the same problem but I wouldn't try to find it. Next thing I was going to suggest is hard unmerge them. But maybe backup the binary packages qith quickpkg before that, just to spare yourself the trouble if there's any.

Georgi

You missed llvm-runtimes/clang-runtime from the above depclean output.
Edit: see Hu's post for something I failed to comment on.

I've trimmed from my quote of your code block each package you actually told Portage to remove. Notice how clang-runtime and clang-toolchain-symlinks are still present. They're not on your depclean line, and they depend on things that are. This is likely why your depclean is failing.

You are not using a bare emerge --ask --depclean, which would remove every unnecessary package that Portage can find.

>>> No packages selected for removal by depclean

I've stripped out the -21 dependencies. The dependencies are all listed in the initial command.

per logrusx's suggestion, I'm going to run `emerge -DuU @world` to remerge everything affected by other USE updates (a whole lot of python, but other packages as well), then run a bare `emerge --ask --depclean` per Hu's suggestion to slog through all the obsolete packages on the system. I guess we'll see how far that gets us.

Only one remark for something that's easy to miss - did you remember to add -1? Check your wolrd file just for any case. Something might be lurking there.

I cleaned up world a bit, removing duplicates, meta-versions, and all the ::gentoo. I don't know what's in @system or in my profile. This world file is *very* old, copied over from backups of much older machines going back probably 20 years. I'm sure a lot of it is obsolete by now.

As for your other comment: neither llvm-core/lldb nor llvm-core/lld-toolchain-symlinks is installed on my system.
