GCC

GNU Compiler Collection (GCC) is one of the most popular compilers for compiling C, C++ and Fortran programs.

In Triton we have various GCC versions installed, but only some of them are actively supported.

Basic usage

Hello world in C

Let’s consider the following Hello world-program (hello.c) written in C.

#include <stdio.h>
int main()
{
   printf("Hello world.\n");
   return 0;
}

After downloading it to a folder, we can compile it with GCC.

First, let’s load up a GCC module:

module load triton/2024.1-gcc gcc/12.3.0

Secondly, let’s compile the code:

gcc -o hello hello.c

Now we can run the program:

./hello

This outputs the expected Hello world-string.

Available installations

System compiler is installed only on the login node. Other versions of GCC are installed as modules and are all part of one of our software stacks. To make them available, you need to first load the appropriate software stack module. Versions labeled “default” are the ones that have been used to build the rest of that software stack.

GCC version	Module name	Software stack
11.5.0	none (on login node only)	none (available by default)
6.5.0	gcc/6.5.0	triton/2024.1-gcc
10.5.0	gcc/10.5.0	triton/2024.1-gcc
11.4.0	gcc/11.4.0	triton/2024.1-gcc
12.3.0 (default)	gcc/12.3.0	triton/2024.1-gcc
13.2.0	gcc/13.2.0	triton/2024.1-gcc
13.3.0 (default)	gcc/13.3.0	triton/2025.1-gcc
