oh i have a strong suspicion why that is and exactly how to fix it (just add it to overridelist_upstream; you could even pr it if you want), but i really am starting to think nixpkgs should have a cppnix alias for nix for anything linking to cppnix... it's really silly that we have to find out about every single one of these.

however, may i suggest nil :p (i know it doesn't do evaluation, but I've never really had the evaluation work anyway)

@jade Thanks, that fixed this issue.

A similar issue is nixos-option getting upgraded to a newer nix and it doesnt build with lix, but using the CLI rather than the C "API" will fix that. But I'm curious why it doesn't work out of the box as it is in overridelist_upstream.
This was recently reported in lix-project/lix#580.

however, may i suggest nil :p

I was using rnix and nil for a long time and recently switched to nixd as I heard it had some big improvements and I also had some minor issues with nil, but may switch back to it in the future :)
