The default C, C++ and Fortran compilers on Ubuntu 22.04 are version 11.4.0 of the GNU cc/gcc, c++/g++ and gfortran compilers.
We have several other C, C++ and Fortran compilers available as environment modules:
- modern Intel C (icx), C++ (icpx) and Fortran (ifx) compilers, version 2026.1.1
- several legacy versions of GNU compilers
To see the available compiler environments run the command:
module avail
Intel compilers
module load intel/compiler
Check by running e.g. "icx --version".
Old GNU compilers
E.g.
module load gcc/7.2.0
if you want version 7.2.0.
Check by running "gcc --version".
