‍Ubuntu is a popular operating system that offers a wide range of features and functionalities for users. One of the key aspects of Ubuntu is its ability to compile and run software applications. To do this, you need to install the GNU Compiler Collection (GCC) and its related tools and libraries. In this article, we will guide you through the process of installing GCC on Ubuntu 23.10.

Step 1: Update System

Before installing GCC, it is essential to update your system to ensure that you have the latest software packages. Open the terminal and run the following commands:

$ apt update

$ apt upgrade

Step 2: Install the Build-Essential Package

The build-essential package is a meta-package that includes the GCC, GNU debugger, and other development libraries and tools required for compiling software. To install it, run the following command:

$ apt install build-essential

Step 3: Check GCC Version

Once you have installed the build-essential package, you can check the version of GCC installed on your system. Open the terminal and type:

$ gcc --version

The output will display the GCC version installed on your Ubuntu system.

Step 4: Compiling a Hello World Example

To ensure that GCC is working correctly, let’s compile a basic C program. Open a text editor and create a new file called hello.c. Insert the following code:

#include <stdio.h>

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

Save the file and return to the terminal. Compile the program using the following command:

$ gcc -o hello hello.c

This will generate an executable file named hello. Run the program by executing the command:

$./hello

You should see the output: “Hello, world!”

Congratulations! You have successfully installed GCC on your Ubuntu 23.10 system and compiled a basic C program.

Conclusion

Installing GCC on Ubuntu 23.10 is a straightforward process that allows you to compile and run software applications on your system.
