How To Install GCC On Ubuntu

In the world of open-source, free software, and Linux-based systems, innovation and collaboration redefine the boundaries of technology. Once a niche operating system, Linux has become a powerhouse known for its reliability, security, and flexibility. Ubuntu, a user-friendly Linux distribution, has made Linux accessible to a broader audience, from beginners to experts. At the heart of this ecosystem lies GCC (GNU Compiler Collection), more than just a compiler; it’s a testament to open-source success, playing a pivotal role in modern development, especially for those venturing into C/C++ programming on open-source platforms.

Introduction

Have you ever wondered about the captivating world of open-source software and Linux-based systems? In this age of digital innovation, it’s natural to feel like an outsider looking in. But fear not, for this blog post is your gateway to a realm where innovation and collaboration redefine the possibilities of technology.

Linux, once a hobby operating system started by one tech enthusiast, has blossomed into a robust and reliable operating system that now underpins a significant portion of the digital world. In this journey, we’ll explore the power of open-source tools, and one such open-source software development tool that plays a significant role in this world is GCC (GNU Compiler Collection). GCC goes beyond being just a piece of software; it’s a key that unlocks the world of coding, allowing you to explore, tinker, and create without limitations.

Throughout this adventure, we’ll be your guides as we demystify the process of installing GCC on your Ubuntu system, making the world of compilers and development tools accessible to everyone. Whether you’re a curious newcomer or a seasoned tech explorer, this blog post will empower you with the knowledge you need to embrace the potential of open source on Ubuntu.

So, fasten your seatbelt, and let’s embark on this journey into the heart of open-source technology, where the world of Ubuntu and the possibilities of GCC await your discovery.

What Is GCC?

GCC, or the “GNU Compiler Collection,” is a suite of powerful compilers used by developers to write and compile code in various programming languages. It’s known for its cross-platform compatibility, support for multiple languages, optimization capabilities, and adherence to industry standards. Being open-source and community-driven, GCC is an essential tool for software development, whether you’re a professional programmer or just starting your coding journey.

Prerequisites

Before we jump into the installation process, let’s make sure you have everything you need:

1. A Running Ubuntu System: You’ll need a working Ubuntu operating system. If you haven’t installed Ubuntu yet, you can find installation guides on the official Ubuntu website.
2. Access to the Terminal: Familiarize yourself with the Ubuntu terminal. It’s the command-line interface where we’ll execute the installation commands. You can usually access it by pressing Ctrl+Alt+T.
3. Sudo Privileges: Ensure that you have sudo privileges. You’ll need these to install software and make system changes. If you’re the system administrator or the primary user of your Ubuntu system, you likely already have sudo access. If not, check with your system administrator.
4. Internet Connection: Make sure you have an active internet connection. We’ll be downloading GCC and its dependencies from online repositories.
5. Basic Terminal Skills: While you don’t need to be a command-line wizard, basic knowledge of terminal commands will be helpful. Don’t worry; we’ll guide you through the process step by step.
6. Storage Space: Ensure that you have enough free storage space on your Ubuntu system. GCC and its associated libraries may require a few hundred megabytes of space.

Installing GCC Compiler On Ubuntu

In this section, we’ll walk you through the process of installing the GCC Compiler on your Ubuntu system. Follow these steps carefully:

Step 1: Open the Terminal

• Press Ctrl+Alt+T on your keyboard to open the Ubuntu terminal. This is where we’ll run the installation commands.

Step 2: Update Package Lists

• Before we install GCC, let’s ensure that our package lists are up to date. Enter the following command and press Enter:

sudo apt update

Step 3: Install GCC

• Now, it’s time to install GCC. Enter the following command and press Enter:

sudo apt install gcc

• Ubuntu will ask you to confirm the installation. Type ‘Y’ and press Enter to proceed.
• This will install GCC from the Ubuntu repositories.

Note if you need other build essentials you may want to install the meta package build-essential instead which contains GCC.

Step 4: Verify the Installation

• To make sure GCC is installed correctly, you can check the compiler version by running the following command:

gcc --version

Practical Example: Compiling And Running Hello World In C

Now that you have GCC installed on your Ubuntu system, let’s put it to use by compiling and running a simple C program. Follow these steps to get hands-on experience:

Example: Hello World in C

1. Open a text editor and create a new file named hello.c.
2. Add the following code to hello.c:

#include <stdio.h>

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

3. Save the file and close the text editor.
4. Open the terminal and navigate to the directory where you saved hello.c.
5. Compile the C program using GCC:

gcc -o hello hello.c

6. Run the compiled binary file:

./hello

You should see “Hello, world!” printed to the terminal.

This example demonstrates how to write a simple C program, compile it using GCC, and run the compiled program on your Ubuntu system. It’s a great way to start your journey into C programming with GCC.

Conclusion
