LLVM 21

VoidAlone

I'm trying to get version 21 set up on my machine through brew. This has worked for me before on other distros (just came from void linux). I'm doing some stuff with experimental features that come with version 21, but it seems as though GCC alternatives, and gcc headers can't be found. I can't compile anything, and clangd freaks out because it can't find any standard library headers.

I think I read somewhere in a very old forum thread that Solus uses non-standard directories for gcc and libraries. Is there a straight forward way to fix this? Solus is otherwise perfect so far, but this hiccup is driving me crazy.

Any help would be much appreciated 😭

I think sudo eopkg install -c system.devel should be able to fix it

Oh sorry I should've mentioned, I did install system.devel but that unfortunately didn't fix it for me.

I've tried uninstalling and reinstalling brew, as well as brew's llvm and lld packages. Solus's own llvm packages obviously work fine.

Does anyone have any insight into this? System.devel as I mentioned doesn't fix it. The problem isn't that the headers aren't there, but rather that they're in a location where llvm doesn't typically look I think. From my limited understanding, the maintainers use alternate locations, which is fine, but I just need a newer version than what's provided in the repos. Not sure if creating some symlinks is viable, or manually updating llvm locally. Any ideas are welcome.

I'll just use nix package manager in the meantime

If you want help, you need to provide more details such as:

the LLVM source,
the exact command you are running,
the errors you are getting (if they are long, put them on a pastebin and share the link here).
