How to Install GCC on Ubuntu 23.10

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
 apt install build-essential

Install the GCC package dependencies.

 apt-get install manpages-dev

Check the GCC version using the below command,

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.
