 aidalgol | Maybe leave out stdenv.cc from the mkShell inputs? | 19:50:57 |
 ornx | no such luck, same error | 19:53:36 |
| ornx | even NIXPKGS_ALLOW_UNFREE=1 nix-shell -p cudaPackages_12.cudatoolkit gives me that error | 19:54:13 |
| ornx | although i'm not sure what commit that's on | 19:54:29 |
| ornx | $ nix-shell -p gcc12 --run 'gcc --version'

| ornx | i'm not sure what is going on here exactly, is it supposed to do that? | 19:55:54 |
| aidalgol | That seems wrong. I get that, too. Also,
❯ nix-shell -p gcc12 --run 'which gcc'
/nix/store/mpm3i0sbqc9svfch6a17179fs64dz2kv-gcc-wrapper-13.3.0/bin/gcc

| ornx | very odd... | 20:02:48 |

| ornx | Ah, so I *was* holding it wrong... | 21:28:01 |

| ornx | i'm having a lot of trouble getting things working still - i'm using devShell.override with cudaPackages.backendStdenv and cuda programs compile and run with nvcc, but i'm getting a cudaErrorInsufficientDriver error even though i'm building my flake against the same revision of nixpkgs that the system was built against | 00:35:00 |
| ornx | actually nvidia-smi in the system env closure has also stopped working so probably there is something wrong with my system flake lol | 00:38:13 |
| ornx | okay yeah even after rebooting and fixing that i get an error when i try to actually run programs i compiled with nvcc | 00:42:55 |
| ornx | is there some kind of mismatch between what driver version cudaPackages.cudatoolkit is expecting and what the system flake is using, even though they're on the same revision and config.boot.kernelPackages.nvidiaPackages is unset? | 00:43:56 |

You did reboot after the switch did you? | 00:45:39 |

| 00:46:13 |
| ornx | i can just merge that PR into a local nixpkgs if that's the fix | 00:46:50 |
