Before I restart my Xcode project from scratch…

Does anyone have experience trying to get an old Xcode project that was running on a ~2016 intel mac with old Xcode, using a C based package dependency, running on a new modern mac that uses nix-darwin? I can’t get it to build.

I am getting weird build errors seemingly related to non existent header file errors. I *suspect* the issue is related to paths somewhere between nix, command line build tools vs xcode, clang stuff from the package, expected paths vs nix paths, etc. However, it may also just be differences in APIs from the old system to the new.

I’ve tried a bunch of things like change the version of clang, interop settings, made sure xcode-select was pointing to xcode not cli tools and whatnot. But I’m stuck. Before I restart this project fresh, if anyone has any potential things to check or tips etc I’m all ears. I’ve tried search and Gemini but to no avail. Any humans out there with suggestions?
