Any pointers on getting Nvidia GPU support built on Linux? I tend to see this (on a machine where
nvidia-smi shows proper support with processes using the GPU as expected):

I asked him about the build too today. He said he'd have to check what build command nix actually uses. Expecting an answer by tomorrow.

github.com/josibake/nix-libbitcoin , this is everything i use currently for building, and up to date. to make it a bit easier, i had claude dump all of the build steps into a stand alone script that doesnt need nix. disclaimer, i haven't testd the standalone script, but it should at least help with picking out the individual build commands being used.

haha take a look at the shell script i linked! that does everything i just mentioned, (applying patches, etc), and doesnt need nix

Yea, absolutely. Just checked out the script, guess that's even more than I need. Thanks.
