@thompsonnoahe I'm looking into this now. Looks like CUDA reserves __noinline__ for it's own purposes, causing this issue: https://stackoverflow.com/questions/70301375/noinline-macro-conflict-between-glib-and-cuda/

Alright I've pushed a fix for this. I'm not easily able to test this myself currently so if you still have further issues feel free to re-open it and I'll have a deeper look into it. Thanks for the report!
