See the GNU C Compiler project page. To use GNU C Compiler, you’ll use the module
tool.
You can see what versions are available by using:
[me@login01 ~]$ module avail gcc
------------------------------ /opt/modulefiles -------------------------------
gcc/9.3.0
Use "module spider" to find all possible modules and extensions.
Use "module keyword key1 key2 ..." to search for all possible modules matching
any of the "keys".
To load a specific version, you would use:
[me@login01 ~]$ module load gcc/9.3.0
while the "gcc" wildcard will load the default version, gcc-9.3.0 in this case.
You should now be able to run GNU C Compiler commands:
[me@login01 ~]$ gcc --version
gcc (GCC) 9.3.0
