Install GCC on Ubuntu 20.04

In this tutorial, we will show you how to install GCC on Ubuntu 20.04 LTS. For those of you who didn’t know, GCC (GNU Compiler Collection) formerly “GNU C Compiler”, is a compiler system produced by the GNU Project. The current version is GCC 9.3, released on March 12, 2020, supporting several major programming languages: C, C++, Objective-C, Objective-C++, Fortran, Ada, D, Go, and BRIG (HSAIL).

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of GCC the C compiler on an Ubuntu 20.04 Focal Fossa server.

To test the C compiler, let’s create a small program like below:

nano hello.c
// hello.c
#include <stdio.h>
int main() {
    printf("Hello, world!\n");
    return 0;

Compile this file with GCC:

gcc hello.c -o hello

The program will result:

Hello World!
