                Cuda on Fedora
              
          
        
      
        
  
      
    Current Fedora 36 does not have/support the latest (open) nvidia drivers, which requires to use an older cuda version 11.8 instead of 12.
However, the g++12 compiler with that fedora is too new for this older cuda, so a custom gcc11 install is required.
Brew solution explained here: https://www.reddit.com/r/Fedora/comments/usnu0x/comment/ig0t9y7/?utm_source=share&utm_medium=web2x&context=3

brew install 'gcc@11'
sudo ln -s /home/linuxbrew/.linuxbrew/Cellar/gcc@11/11.3.0/bin/g++-11 /usr/local/cuda/bin/g++

At some point, this causes some trouble after dynamically linking to a different libstdc++, which can be solved by making nvcc pass a static linking flag:
