In this tutorial, you will install GCC on Ubuntu 22.04. We will also address a few FAQs on how to install GCC on Ubuntu 22.04.

Advantages of GCC

  1. Open-Source: GCC is freely available and can be modified to suit specific needs, making it a preferred choice for developers.
  2. Language Support: GCC supports multiple programming languages, including C, C++, and Fortran, providing flexibility to developers.
  3. Portability: GCC generates machine code for various platforms, allowing software to run seamlessly on different systems.
  4. Optimization: GCC offers advanced optimization techniques, improving code performance and efficiency.
  5. Community Support: With a large user community, GCC benefits from continuous improvements, bug fixes, and support from experienced developers.

How to install GCC on Ubuntu 22.04

Please refer to the instructions provided below if you want to install GCC on Ubuntu 22.04.

Step 1 - Update the system

Update your Ubuntu 22.04 by running the following command before installing GCC. This is done to ensure that all relevant packages are updated and no conflicts arise.

sudo apt update

Step 2 – Install GCC

Installing the build-essential package, which includes packages for GCC and numerous other packages, is then advised.

sudo apt install build-essential -y

Step 3 – Evuate the Installation

Now, use the following command to check the C compiler version to see if GCC was successfully installed.

gcc --version
Output

gcc (Ubuntu 11.3.0-1ubuntu1~22.04.1) 11.3.0
Copyright (C) 2021 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Step 4 - Create a C program

Once installed, test the compiler's functionality by writing a simple C program. For instance, in the example below, we developed a basic hello world C program and saved the file as hello.c.

nano hello.c
#include <stdio.h>
int main()
{
  printf ("Hello World!\n");
  return 0;
}

This file should be saved and made executable.

gcc -o hello hello.c

The hello binary file will be created by this command and placed in the same directory. Now you have to execute the program using the below-mentioned command.

./hello
Output

Hello World!

The C program was successfully run.

Congratulations! You have successfully installed GCC on Ubuntu 22.04.
