How To Install GCC on CentOS 7

In this tutorial, we will show you how to install GCC on CentOS 7. For those of you who didn’t know, GCC or GNU Compiler Collection is released by the Free Software Foundation and as the name suggests, it is a very useful collection of programming compilers such as C, C++, Objective-C, Objective-C++, Fortran, Java, Go. GCC is an official compiler of the GNU operating system but also it is a standard compiler on many Unix operating systems such as Linux.

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 install GCC Compiler on CentOS 7 server.

Prerequisites

• A server running one of the following operating systems: CentOS 7.
• 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.
