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