@niclas:overby.meNiclas Overby Ⓝ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?08:08:09
@hacker1024:matrix.orghacker1024nixGL has worked for me in the past08:56:54
@hacker1024:matrix.orghacker1024Technically that finds a kernel-compatible libcuda.so in Nixpkgs08:57:24

If you create a /run/opengl-driver/lib (it might be called something slightly different) folder and symlink all the cuda kernel mode drivers in there. It should work out of the box

@sporeray:matrix.orgRobbie Buxton You need to add this folder to the rpaths of those drivers too others they can’t find each other 14:41:38
