 connor (he/him) | Interesting byproduct of getting rid of the CUDA stdenv is having libraries produced by multiple versions of a compiler, which breaks LTO: https://github.com/ConnorBaker/cuda-packages/commit/87cb387ecfba3f46b76e604b896d64417fdf9e8b | 16:15:00 |

 hexa | yes | 17:03:53 |
| Gaétan Lepage | Ok thanks | 17:05:39 |

Maybe .override { cudaSupport = true; } should have been .override { stdenv = cudaStdenv; } in the first place. All lib.optionals cudaSupport should have been lib.optionals stdenv.isCuda or stdenv.isNVCC. We could remove (move to stdenv) all cuda- or hip-related flags, but the easiest way to do that is to make config.cudaSupport replace the actual default stdenv for all packages, triggering even more rebuilds than we do now.
Accidentally, this would also make it easier to move config.cudaSupport into crossSystem and introduce a pkgsCross.cuda.

 caniko | Does ollama still require compiling CUDA? | 20:16:41 |
| caniko | I failed to compile last time, and actually have no interest in doing so... | 20:17:44 |
| SomeoneSerge (matrix works sometimes) | It's optional | 21:13:16 |

| SomeoneSerge (matrix works sometimes) | * CUDA support is optional. If you enable it you have to rebuild ollama. It should be cached in nix-community cachix | 21:14:50 |

| SomeoneSerge (matrix works sometimes) | connor (he/him) (UTC-7): we never published that community update, you think you'd be able to find the time to push that over the line? | 14:37:45 |

| connor (he/him) | Ah yeah; do you remember if I had a draft or if you did? | 06:31:29 |

| caniko | perhaps something changed? | 14:31:42 |
| caniko | I just checked, it has parts that are written in C 😄 | 14:33:59 |
