What is GCC?

The GNU Compiler Collection (GCC) is a key tool in software development. It offers a suite of compilers supporting languages such as C, C++, and Fortran. Originally designed for the GNU operating system, GCC has grown to support many programming languages and operating systems, including openSUSE.

Why You Should Install GCC on openSUSE?

Installing GCC on your openSUSE system enables you to compile and run various programming languages, making it a must-have tool for developers.

Prerequisites for Installing GCC on openSUSE

Before installing GCC on openSUSE, ensure that the following requirements are met:

  • A server running openSUSE
  • A fresh OS install to prevent potential issues
  • Access to the terminal
  • An active internet connection
  • Administrative (root) access or a user account with sudo privileges

Steps to Install GCC on openSUSE

Step 1: Update Your System

Before installing GCC, ensure your system is up-to-date by running the following commands in your terminal:

sudo zypper refresh
sudo zypper update

Step 2: Enable the Open Source Software (OSS) Repository

Enabling the OSS repository grants access to the GCC packages. You can do this through the YaST software management tool or directly via the terminal with the following command:

sudo zypper addrepo http://download.opensuse.org/distribution/leap/15.6/repo/oss/ oss

Step 3: Search for Available GCC Packages

With your system prepared, search for available GCC packages using the zypper search command:

zypper search gcc

Step 4: Install GCC Compiler

To install the GCC compiler, use this command:

sudo zypper install gcc

If you plan on compiling C++ programs, you’ll also need to install the gcc-c++ package:

sudo zypper install gcc-c++

Step 5: Verify GCC Installation

After installing GCC, it’s good practice to verify that it’s correctly installed on your system. Check the installed version of GCC and G++ (the GNU C++ compiler) with:

gcc --version
g++ --version

If the commands return the GCC and G++ version numbers, then you have successfully installed GCC on your openSUSE system.
