Interesting, running nix-shell --pure with the previous shell.nix would work. Is this due to nix channel version?

I think they are searching the path for llvm-config, which should be present if we have llvm in our dependencies.

It works on the master branch indeed, but it seems you updated some crates in the hm-inference branch.

I just cloned the repository on zeus, removed the LLVM_SYS_100_PREFIX, and did a nix-shell --pure --run "cd nac3core && cargo test". It works fine. Weird problem... Anyway this is not a big issue.

Can't reproduce it either with the latest nixpkgs 21.05 channel.
