[Feature Request] Remove `-ccbin` flag on demand #1084

Closed QuarticCat closed 1 month ago

QuarticCat commented 1 month ago

On Arch Linux, without the -ccbin flag, nvcc will choose g++-13 by default. However, cc generates -ccbin=c++ which links to GCC 14, causing compile errors. Although on my own machine, I can specify the CXX environment variable, I can't simply fix the version for lib users. The best way to fix this problem is to remove the -ccbin flag and let nvcc decide host compiler by itself.

Having a new function for this does sound reasonable.

I will accept a PR for this new function.

Thx. I'll have a try.
