gcc-12 include errors in cmake, CUDA project

Hi,
Latest Cuda (11.6) is not well compatible with gcc-12, which is now default in Arch Linux.
I got errors when building cmake project, while trying to include GRPC and other libraries, which works in .cpp gcc, but not in .cu file.
I figured out, that this is related to gcc-12. I installed gcc-11 from official repo, but compiling with cmake still points to */usr/include/c++/12.1.0/* but not to */usr/lib/gcc/x86_64-pc-linux-gnu/11.3.0/include/*
I am using vscode, I changed my kit to gcc-11, but that doesn't effect on building .cu files with cmake, while it effects only building .cpp files.
Where could problem be? What workaround could be made?

Thanks in advance

Re: gcc-12 include errors in cmake, CUDA project

archlinux cuda maintainer appears to be working on building cuda 11.7 against gcc11 , https://archlinux.org/packages/communit … 6_64/cuda/ .

Maybe you could try that PKGBUILD ?

Sidenote :
building programs for use on archlinux through Integrated Development Environment methods tends to be much harder then using pacman/makepkg .

(the same goes for manual installations)
