GCC, or GNU Compiler Collection is a compiler system for C, C++, Objective-C, Objective-C++, Fortran, Ada, D, Go, and BRIG (HSAIL) programming languages. These compilers can be on used on Windows, Linux and many other operating systems. It’s produced by the GNU Project and the current version is GCC 12.2. In this article we will explain how to install GCC on Ubuntu 22.04.
How to install GCC on Ubuntu 22.04
Perform the following steps to install GCC on Ubuntu 22.04 system:
Step 1 – Update System
At first, you have to update the system before start installation of GCC. It will update all the dependent packages. Run the below given command to update system:
sudo apt update
Step 2 – Install GCC
After that, you should install the build-essential which consists of packages of GCC. The build-essential package is available in default Ubuntu repositories. It includes GNU compiler collection and entire development package.
Issue the following command to install the Development Tools packages as root or user with sudo privileges:
sudo apt install build-essential
Step 3 – Verify Installation
Once the installation is complete, you can verify the version by typing:
gcc --version
It should print the following output:

nano welcome.c
#include <stdio.h>
int main() {
printf("You're welcome!\n");
return 0;
}
Save it as welcome.c and compile it using following command:
gcc -o welcome welcome.c
The above command will create a binary file named welcome in the current working directory.
To execute program, type:
./welcome
It will show output as following:
You're welcome!
