 connor (burnt/out) (UTC-8) | This was also a great way to find out that on master the wrong version of cuDNN is selected when building for Jetson (we get the x86 binary) — that’s mostly why the flake is using my PR with CUDA 13 and the packaging refactor | 14:29:02 |

 Niclas 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 | nixGL has worked for me in the past | 08:56:54 |
| hacker1024 | Technically that finds a kernel-compatible libcuda.so in Nixpkgs | 08:57:24 |

Can it be done with LD_LIBRARY_PATH or LD_PRELOAD? 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 | 14:40:53 |

| Robbie Buxton | You need to add this folder to the rpaths of those drivers too others they can’t find each other | 14:41:38 |

| connor (burnt/out) (UTC-8) | Both nixGL and nixglhost should work I’ve also had success doing what Robbie outlined
I’ve also been able to export LD_LIBRARY_PATH and that’s worked as well | 15:02:28 |
