Preparing portal / portal2

Tip

Review how to access our remote servers portal / portal2.

The default compilers on portal and portal2 are GCC 11. These are quite old, and don’t support all of the language features we need. The GCC 15 compilers are available however, so we can use those instead. To activate them, we need to do:

scl enable gcc-toolset-15 bash

This will create a new Bash shell with the environment variables set to point to this version of the compilers.

It is not recommended to add this command directly to our .bashrc, but we can instead source a script that accomplishes the same setup by adding:

source /opt/rh/gcc-toolset-15/enable

to the end of our .bashrc.

You’ll need to log in again for this to take effect.

Important

You need to modify portal and portal2 separately. Files are not shared between the machines.

Tip

You can check which version of the compilers are active by doing:

g++ --version
