And I ran llvm-config --version:

Hi! Thanks for the report.

Could you provide some additional information about your host system? this looks like an issue with llvm-sys crate which we rely on to hook up with LLVM.

[0xMRTT]

Arch Linux with llvm and llvm-libs installed. I think that the error is with inkwell and when I run llvm-config --system-libs, i get nothing. Which other informations should i provide ?

[feds01]

I think there is an open issue on llvm-sys crate about compiling it on Arch-like systems: https://gitlab.com/taricorp/llvm-sys.rs/-/issues/42.

It also seems that there is work to fix this issue https://gitlab.com/taricorp/llvm-sys.rs/-/merge_requests/31, hopefully this will get merged soon and we will upgrade on our end.
