 connor (he/him) | if anyone enjoys the process of bumping opencv looks like 4.11 is out now (master is still using 4.9) | 07:51:29 |
 Gaétan Lepage | Has to happen on staging right ? | 07:52:29 |
| connor (he/him) | I think so due to the number of rebuilds | 07:54:12 |
| connor (he/him) | Good news is that 4.10 fixes compilation with CUDA 12.3+ | 07:54:34 |
| 18 Jan 2025 |
| connor (he/him) | just updated https://github.com/connorbaker/nix-cuda-test to use the latest changes in https://github.com/ConnorBaker/cuda-packages, which include getting rid of the need for a custom CUDA stdenv | 08:51:19 |
| connor (he/him) | At least, I’m fairly certain I’ve implemented it that way. I’ve also got a setup hook which checks for RPATHs in produced libraries that match library directories from NVCC’s host compiler | 09:35:02 |

if anyone enjoys the process of bumping opencv looks like 4.11 is out now (master is still using 4.9) I'm looking for some reviewers ;)
https://github.com/NixOS/nixpkgs/pull/374246 | 09:45:39 |
| connor (he/him) | I’ll try to take a look this weekend to see if I can help with the tests/fill the missing hashes | 09:53:14 |
 hexa | connor (he/him) (UTC-7): can you respond to the commonts on the onnxruntime PR? https://github.com/NixOS/nixpkgs/pull/364362 | 14:49:05 |
| hexa | I think it is only blocked on those, and I'd like to build upon the PR | 14:49:22 |
| connor (he/him) | How are there so many rebuilds for that PR? Is it taking the number of rebuilds against master? | 18:38:30 |
| hexa | eigen | 18:49:16 |
| hexa | * that is due to the eigen bump | 18:49:22 |
| hexa | * that is due to the eigen bump, I believe | 18:52:05 |
| Gaétan Lepage | On which infra are the cuda derivations (which since a few months, are cached on the nix-community cachix) built ? | 22:57:27 |

| 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 |

https://hydra.nix-community.org/project/nixpkgs So on the nix-community CI builders ? | 17:01:35 |
| 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 (back on matrix) | It's optional | 21:13:16 |
|  oak 🏳️🌈♥️ changed their profile picture. | 22:35:37 |
| SomeoneSerge (back on matrix) | * CUDA support is optional. If you enable it you have to rebuild ollama. It should be cached in nix-community cachix | 21:14:50 |
