Code::Blocks is a free C, C++ and Fortran IDE available on Linux, Windows and Mac. It is designed to be very extensible and fully configurable. It is a graphical application so you will need to use either via ThinLinc (recommended) or via SSH X-forwarding to start it at NSC.
In a terminal, load the desired module with e.g.
module load codeblocks/13.12
We recommend that you choose the latest version available unless you have specific reasons not to. Start the application by invoking it on the commadline
