Description
Compatibility package for running GCC on Fedora. Required for current CUDA packages. This tracks the current CUDA release and the current Fedora releases when an incompatibility arises.

Installation Instructions
When running the CUDA stack on a recent Fedora distribution, you’re very likely to hit the compatibility issue with the current GCC release not being yet supported by NVCC. This is quite easy to address, but not many people seem to know it.
Since a few years I’ve been shipping a cuda-gcc package which appears as a drop in replacement for NVCC. It can be installed along with CUDA and the drivers to run the upstream CUDA packages provided by Nvidia.
Originally it was a custom built GCC, but now this package now simply uses the compatibility GCC package provided by Fedora:
$ sudo dnf install cuda-gcc

And then sets the necessary environment variable to override the NVCC detected GCC binary:
$ cat /etc/profile.d/cuda-gcc.sh
export NVCC_CCBIN='g++-13'
# Alternatively you can use the following:
export NVCC_PREPEND_FLAGS='-ccbin /usr/bin/g++-13'
Logout/login or reload your profile and you’re good to go.
This way, every time you invoke NVCC you are not using the system compiler but the one provided by the cuda-gcc package.
On a Red Hat Enterprise Linux based distribution you can achieve the same result by installing the development toolset of your choice and activating the environment for it. This is usually not an issue as NVCC is officially supported on those distributions.
