GNU compilers

The GNU compilers installed with the OS on DelftBlue is quite old. If you load the current software stack, followed by module load gcc, you will get a more recent version that was used to build the stack itself. For example, module load 2025 gcc will load gcc/13.2.0. It is recommended to compile (as much as possible) everything with the same version of the compiler. Other versions may exist as well, use module spider gcc to search the module system, or install your own using spack.
