How To Install GCC on CentOS 8

Install GCC on CentOS 8

In this tutorial, we will show you how to install GCC on CentOS 8. For those of you who didn’t know, The GNU Compiler Collection (GCC) is a collection of compilers and libraries for C, C++, Objective-C, Fortran, Ada, Go, and D, programming languages. A lot of open-source projects, including the Linux kernel and GNU tools, are compiled using GCC.

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 the step-by-step installation of GCC on a CentOS 8 server.


  • A server running one of the following operating systems: CentOS 8.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

gcc hello.c -o hello
