Since Fedora 28, the OS install GCC 8.X version. How can I install or compile GCC 7.3 in Fedora 29? I got such an error after trying to compile an open source project:

/usr/local/cuda-10.0/include/crt/host_config.h:129:2: error: #error -- unsupported GNU version! gcc versions later than 7 are not supported!
#error -- unsupported GNU version! gcc versions later than 7 are not supported!
^~~~~

I've read this GCC documentation https://gcc.gnu.org/install/index.html. However, I still cannot understand everything.

Try installing older gcc version with

dnf install gcc-compat*

You can use the newer gcc v8.X, by passing the —override option to the .run file (assuming you downloaded the .run file for CUDA installation from the NVIDIA website). Otherwise if you have already installed as pointed in the other answer you can gcc-compat* to install the older version of gcc.

Just out of curiosity, are you sure cuda will eventually compile with newest gcc? My experience says "no way".

I installed CUDA on my system couple of days ago, by running the .run file downloaded from NVIDIA with the flag —override and it installed it successfully and tested one of the sample apps that come with CUDA and worked fine.

You're talking about a beta. Moreover I would like to see something with cuda compiled by the latest gcc, not just the samples directory.
