Installing GCC on Linux: A Comprehensive Guide

Introduction

In the world of Linux development, having a robust and reliable compiler is essential. The GNU Compiler Collection, or GCC, is a cornerstone for compiling and building applications on Linux systems. In this guide, we’ll walk you through the step-by-step process of installing GCC on your Linux distribution, whether you’re a seasoned developer or a newcomer to the Linux environment.

Understanding GCC

Before we delve into the installation process, let’s briefly explore what GCC is and why it’s indispensable for Linux developers.

What is GCC?

GCC is a powerful, open-source compiler that supports various programming languages, including C, C++, and Fortran. It plays a pivotal role in converting human-readable source code into machine-executable code, facilitating the creation of applications and software on Linux systems.
