@connorbaker:matrix.orgconnor (he/him)That’s partly why my packaging of Onnxruntime involves rewriting some of their CMake files16:34:35
@connorbaker:matrix.orgconnor (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
@connorbaker:matrix.orgconnor (he/him)God what a nightmare16:36:36
@connorbaker:matrix.orgconnor (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
@connorbaker:matrix.orgconnor (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
@glepage:matrix.orgGaétan LepageThanks for taking the time to look at it and explain all of this !21:26:24

@msanft:matrix.orgMoritz 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
@msanft:matrix.orgMoritz 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

EDIT: No, it indeed seems to try and find GCC:
