Arch Linux

I just realised that I was mentioning nvidia driver version numbers instead of cuda version numbers, so afaict it affects cuda 11.8 (see: https://docs.nvidia.com/deploy/cuda-compatibility/index.html#installing-from-network-repo ) onwards since cuda 11.8 was the version that introduced this shared library, on that note this likely should be on the packages category instead of packages: testing since cuda 11.8 is in the normal packages, I'm not sure if I can change that myself and if so how to do it however so I haven't changed that

I can't reproduce. So I'm on cuda 11.8, I run `cuda-gdb /my/binary` and I'm supposed to see some errors? Which shared file is even supposedly missing, anyway? Can you provide a patch for the PKGBUILD that fixes the problem for you?

The file that was missing for me is `libcudadebugger.so.1`, as the forum post says, I can't currently test it (I'll be home in a couple of hours)

Upon further investigation, it appears that `libcuda` etc are provided by `nvidia-utils`, `libcudadebugger.so` is not provided by that.
I'm not sure why it isn't failing for you, since I tested both cuda 11.8 and cuda 12, which both fail

Thank you for the description, was able to repro with that. I think rel 3 of nvidia-utils fixes it. Please test!

Yep that fixed it! Thanks!
