Installing GCC on Ubuntu 22.10

Hello,

In this week’s feature highlight, we look at How to Install GCC on Ubuntu 22.10

The default Ubuntu repositories contain a meta-package named “build-essential” that includes the GNU compiler collection, GNU debugger, and other development libraries and tools required for compiling software.

Update System

 apt update

Install the GCC package dependencies.

 apt install build-essential

To check GCC version

 gcc --version

Output:

root@crown:~# gcc --version
gcc (Ubuntu 12.2.0-3ubuntu1) 12.2.0
Copyright (C) 2022 Free Software Foundation, Inc.

That’s it. GCC tools and libraries have been installed on your Ubuntu system.

Compiling a Hello World Example

Compiling a basic C or C++ program using GCC is pretty easy. For example let’s create a hello world C program. Save the following code as hello.c text file:

 nano hello.c

// hello.c
#include <stdio.h>

int main() {
    printf("Hello, world!\n");
    return 0;
}

Save the file and compile it into an executable:

$ gcc -o hello hello.c 
$ ./hello 
 Hello, world!

Done.
