 connor (he/him) | I also love that onnx by default builds with ONNX_ML=0 (disabling old APIs in favor of new ones), but various projects depend on it being set to one value or the other, so you could very easily end up with two copies of onnx, each configured with a different value for ONNX_ML. | 16:36:22 |
| connor (he/him) | God what a nightmare | 16:36:36 |
| connor (he/him) | We should also update OpenCV at some point to 4.10 if we haven’t already so it can build with CUDA 12.4+ | 16:38:16 |
| connor (he/him) | Oh! Unrelated but this was a cute change I made that I quite like: https://github.com/ConnorBaker/cuda-packages/blob/c81a6595f07456c6cc34d8976031c4fa972a741f/cudaPackages-common/backendStdenv.nix#L36
Sets some defaults for the CUDA stdenv and adds a name prefix, similar to what the Python packaging does, for more descriptive store paths | 16:40:07 |
 Gaétan Lepage | Thanks for taking the time to look at it and explain all of this ! | 21:26:24 |

 Moritz Sanft | Does anyone of you use clangd as a C LSP, with cudatoolkit coming from a shell? clangd seems not to take notice of CUDA in that case, saying Cannot find CUDA installation; ... | 07:54:44 |
| Moritz Sanft | Also, does cudatoolkit miss a dependency on gcc, or am I mistaken by this error:
✖ nvcc main.cu
gcc: No such file or directory

Yea we don't link gcc directly in nvcc but provide it independently via the overridden stdenv | 09:40:39 |

The topic is interesting. Imagine being able to have a massive decentralized build farm ! That would be amazing.
Of course this is far from possible today (mostly because of nix limitations). A horror security-wise though xD | 11:08:32 |

| SomeoneSerge (back on matrix) | connor (he/him) (UTC-7): hiya, any idea why there's nothing like find_package(protobuf) in onnx/onnx before it tests for TARGET protobuf::libprotobuf[-lite]? Is it supposed to inherit these variables from onnxruntime or something? | 15:32:43 |
| 28 Oct 2024 |
| connor (he/him) | I would have thought that, but ONNX is also built directly and not just as a dependency of onnxruntime, so I don’t think it’s because they intend ONNX to be built solely as a subproject and leave configuration up to the parent
I don’t understand how they expect it to be magically detected… but it works for me from what I remember (https://github.com/ConnorBaker/cuda-packages/blob/main/cudaPackages-common/onnx.nix)
Although I’m doing the cursed C++/Python install and had to carefully choose dependencies from the normal package set and from Python packages 🤷♂️ | 06:39:55 |

| SomeoneSerge (back on matrix) | Could help with upstreaming the tricks | 15:24:30 |
| SomeoneSerge (back on matrix) | Btw at NixCon Tom brought up moving cudaSupport &el into the system which I think was raised here at least on a few occasions | 15:26:05 |

| SomeoneSerge (back on matrix) | We could even skip exposing nixpkgsFun in the public api then: could be just pkgsCross.cuda | 15:27:51 |

Btw at NixCon Tom brought up moving cudaSupport &al into the system which I think was raised here at least on a few occasions I’d really like capabilities to exposed as part of potential pkgsCross because they are effectively a platform target for the purposes of codegen; thoughts? | 19:02:51 |
