Thank you, @manueldeprada. The how-to was something I tried with success some time ago. I updated your list to fetch gcc/g++ 12.3 (edits applied to the top post).

wget ${url}/g/gcc-12/cpp-12_12.3.0-11_amd64.deb
wget ${url}/g/gcc-12/g++-12_12.3.0-11_amd64.deb
wget ${url}/g/gcc-12/gcc-12_12.3.0-11_amd64.deb
wget ${url}/g/gcc-12/gcc-12-base_12.3.0-11_amd64.deb
wget ${url}/g/gcc-12/libgcc-12-dev_12.3.0-11_amd64.deb
wget ${url}/g/gcc-12/libstdc++-12-dev_12.3.0-11_amd64.deb

If gcc-12 is not in your PATH, an extra step for NVIDIA CUDA is defaulting to gcc-12 via a symbolic link in the same folder where nvcc resides.

sudo ln -s /opt/gcc-12/bin/gcc /opt/cuda/bin/gcc

Thanks!

This gist resolve big problem for me in nvcc with cuda

Your welcome, @aashahin. I updated the list to fetch cpp, g++, gcc, gcc-12-base, libgcc-12-dev, and libstdc++-12-dev version 12_12.3.0-13. The prior version 12_12.3.0-11 no longer exists.

I followed the mirror and changed the version numbers that didn't work, again thank you

I modified the gcc 12.3 spec file (from FC37) to build packages that can install alongside the system gcc installation. Find my instructions here.

++ @ulatekh Very cool.
