Various things which need to be fixed outside of the CUDA 13 PR:

• patchelf breaking Jeston binaries because of invalid binary modifications (there’s an open issue for this on Nixpkgs IIRC)
• packages with stubs should provide a setup hook which replaces the stub in the run path with wherever the library will be found at runtime (without duplicating run path entries — this is part of what started me making arrayUtilities setup hooks)
• cuda compat library precedence in run path entries is or can be lower than /run/opengl-driver/lib so it won’t be used; need to update hook to fix that (the other driving force behind arrayUtilities)
• Support for Clang as a host compiler for backendStdenv
• investigate cc-wrapper scripts to see if there’s anything relevant for NVCC (like random seed, or anything which enables deterministic compilation and linking)

There are others but I can’t remember them :/

And if anyone wanted to run the demo, I've packaged it with a flake: https://github.com/ConnorBaker/ContinuousSR

Still need to download the model from their google drive (https://github.com/ConnorBaker/ContinuousSR?tab=readme-ov-file#pretrained-model)

SomeoneSerge (back on matrix)
what if 👉👈
you merged my CUDA 13 PR 🥺

In reply to @niclas:overby.me
Are there any good resources for getting CUDA projects, built with CUDA packages from Nixpkgs, running with libcuda.so provided by a non-NixOS host?
Can it be done with LD_LIBRARY_PATH or LD_PRELOAD?
