How to Install GCC in Windows 11: A Step-by-Step Guide for Beginners

Installing GCC on Windows 11 is straightforward if you follow the right steps. You’ll need MinGW-w64, a toolchain that allows you to compile C and C++ code. This guide will walk you through downloading, installing, and setting up GCC in a way that’s easy to follow.

How to Install GCC in Windows 11

Installing GCC on Windows 11 involves downloading MinGW-w64, setting it up, and configuring your environment variables. By the end, you’ll have a working C/C++ compiler on your system.

Step 1: Download MinGW-w64

First, download the MinGW-w64 installer from its official website or a trusted mirror.

When you visit the MinGW-w64 website, look for a download link or button. Make sure you’re downloading the installer compatible with Windows. Most of the time, it’s easy to spot.

Step 2: Run the Installer

Once downloaded, run the MinGW-w64 installer.

Open the downloaded file, and it will launch the installation wizard. Follow the on-screen instructions to proceed with the installation. Choose the installation directory, which is often set by default but can be customized.

Step 3: Select the Components

Choose the components you need for your GCC setup by checking the appropriate options.

In the components section, make sure you select both the C and C++ compilers. These are essential for most development tasks. You might also see other tools and libraries you can install.

Step 4: Complete the Installation

Click "Next" and let the installer complete the installation process.

This process might take a few minutes. Once done, you’ll see a confirmation screen. Click "Finish" to close the installer. Your GCC setup is almost complete.

Step 5: Set Environment Variables

Go to your system settings and adjust the environment variables to include the path to MinGW-w64.

Open the Start Menu, type "Environment Variables," and select "Edit the system environment variables." Under the System Properties window, click "Environment Variables." Add the path to the MinGW-w64 bin folder to the PATH variable. This step tells your system where to find the compiler.

Step 6: Verify the Installation

Open Command Prompt and type gcc --version to make sure GCC is installed correctly.

If everything is set up properly, you should see the version number of GCC displayed. This means your installation was successful, and you can now compile C and C++ programs on your Windows 11 machine.

After completing these steps, you should have GCC set up and ready to go. You can now compile and run your C and C++ programs from the command line.
