I am trying to package a CAD system (BricsCAD) for Nix, which has many of its dependencies bundled in the download. I found as many as I could using nix-locate, and included those in the build inputs, but there are still a lot of libraries that aren’t available in nixpkgs from what I can tell.
I am trying to use autopatchelf as described on the NixOS Wiki. I am copying all of the included libraries to $out/lib during the install phase, they have execute permissions already, and it builds without any error. However, when I try to run the binary I get the error:
zsh: no such file or directory: ./result/bin/bricscad
And running ldd on the binary shows most of the dependencies are not found.
From my understanding, autopatchelf expects these dependencies from other packages in nixpkgs to be in $out/lib for the respective packages, but does not seem to find them when they are part of the package I am trying to build. I have tried a few other things but haven’t found anything that works yet.
Do I need to do something with makeWrapper, or are there other flags I can pass to autopatchelf to have it use the provided libraries?
I feel like I’m missing something obvious, I’m pretty new to Nix and I’m not a programmer, so I don’t really have the best understanding of what is really going on.
