How to Install GCC in Windows 11 — A Step-by-Step Guide

If you’re a C or C++ programmer, you’ve probably heard of GCC (GNU Compiler Collection) — the gold standard for compiling C, C++, and other programming languages. But setting it up on Windows 11 can seem tricky at first. Don’t worry — this guide will walk you step-by-step through how to install GCC in Windows 11, configure your environment, and verify it’s working correctly.

By the end, you’ll have a fully functional GCC compiler running smoothly on your Windows 11 PC — ready for your coding adventures!

🧠 What Is GCC?

GCC, short for GNU Compiler Collection, is a free, open-source compiler developed by the GNU Project. It supports multiple programming languages including C, C++, Fortran, Objective-C, Ada, and more.

Think of it as a translator — GCC converts the human-readable source code you write into machine code your computer can execute.

⚙️ Why Install GCC on Windows 11?

If you want to compile C or C++ programs locally, you’ll need a compiler — and GCC is one of the most reliable and widely used.

Here’s why developers prefer it:

• ✅ Cross-platform compatibility (Windows, Linux, macOS)

• ✅ Supports multiple languages

• ✅ Follows modern language standards

• ✅ Highly optimized and efficient

• ✅ Free and open source

Installing GCC on Windows lets you write, compile, and run programs directly from your terminal or IDE, just like you would on Linux.

🛠️ Different Ways to Install GCC on Windows 11

There are multiple methods to install GCC in Windows 11. The two most common are:

1. Using MinGW (Minimalist GNU for Windows)

2. Using MSYS2 (Modern alternative with package manager)

Let’s explore both step by step.

---

🧩 Method 1: Install GCC Using MinGW

MinGW (Minimalist GNU for Windows) provides a native build of GCC for Windows. This is one of the simplest ways to install GCC.

Step 1: Download MinGW Installer

1. Visit the official MinGW website: https://osdn.net/projects/mingw/

2. Click “Download the latest version of MinGW”.

3. This will download a file like mingw-get-setup.exe.

Step 2: Run the Installer

1. Double-click the downloaded mingw-get-setup.exe file.

2. Choose an installation directory — for example:

   C:\MinGW


3. Click Continue and allow it to install.

Step 3: Select Packages to Install

Once the installation manager opens:

1. In the left pane, click Basic Setup.

2. In the list, check the box next to:

   • mingw32-gcc-g++ → C and C++ compiler

   • mingw32-gcc-objc (optional)

3. Right-click and select Mark for Installation.

4. Then click Installation → Apply Changes.

The tool will download and install all selected components.

Step 4: Add GCC to System PATH

Now, we need to tell Windows where GCC is installed so you can run it from any directory.

1. Press Win + S, type Environment Variables, and open Edit the system environment variables.

2. Click Environment Variables… at the bottom.

3. Under System variables, find and select Path, then click Edit.

4. Click New, and add this line:

   C:\MinGW\bin


5. Click OK on all windows to save.

Step 5: Verify GCC Installation

To confirm everything is working:

1. Open Command Prompt (Win + R → type cmd).

2. Type:

   gcc --version


3. If you see output like this:

   gcc (GCC) 12.2.0


   🎉 Congratulations! GCC is successfully installed.

🧱 Method 2: Install GCC Using MSYS2

MSYS2 is a more modern and feature-rich way to install GCC on Windows. It provides a package manager (pacman) like Linux, making updates and dependency management easier.

Step 1: Download MSYS2 Installer

1. Visit https://www.msys2.org/.

2. Download the MSYS2 installer for your system (usually msys2-x86_64.exe).

Step 2: Install MSYS2

1. Run the downloaded file and follow the setup wizard.

2. Choose a location like:

   C:\msys64


3. Click Finish to complete the installation.

Step 3: Update the Package Database

After installation:

1. Open the MSYS2 MSYS terminal from the Start Menu.

2. Update the package database and core system using:

   pacman -Syu


3. Close the terminal after it updates, then reopen and run:

   pacman -Su


Step 4: Install GCC Compiler

Now, let’s install the GCC package:

Step 5: Add MSYS2 GCC to PATH

To use GCC from the Windows Command Prompt or PowerShell:

1. Copy the path:

   C:\msys64\ucrt64\bin


2. Add it to your system PATH as explained in Method 1, Step 4.

Step 6: Verify GCC Installation

1. Open Command Prompt or PowerShell.

2. Run:

   gcc --version


3. You should see version details confirming successful installation.

🧩 Comparing MinGW vs MSYS2

If you’re a beginner, MinGW is great to start with. If you want flexibility, MSYS2 is the modern choice.

---

🧩 Optional: Install Code::Blocks IDE with GCC

If you prefer an IDE over command line tools, you can install Code::Blocks with GCC preconfigured.

1. Go to https://www.codeblocks.org/downloads/.

2. Download the version labeled “codeblocks-xx.xmingw-setup.exe”.

3. Install it and run Code::Blocks — GCC will already be included.

This is the easiest way to start coding in C/C++ without manually configuring GCC.

---

💡 How to Test GCC After Installation

To ensure GCC works properly, let’s compile a simple C program.

1. Create a new file called hello.c and add:

   #include <stdio.h>

   int main() {
printf("Hello, GCC on Windows 11!\n");
return 0;
}


2. Open Command Prompt in the file’s directory.

3. Type:

   gcc hello.c -o hello


4. Then run:

   hello


5. You should see:

   Hello, GCC on Windows 11!


If you see this message — congratulations, you’ve successfully installed and tested GCC!

🔧 Common Errors and How to Fix Them

❌ “gcc is not recognized as an internal or external command”

Cause: The system PATH is not set correctly.
Fix:

• Add the correct path to your GCC installation (e.g., C:\MinGW\bin or C:\msys64\ucrt64\bin) in the Environment Variables.

⚠️ “Compilation failed” or “File not found”

Cause: You’re not in the same directory as your source file.
Fix:

• Navigate to the folder containing your .c or .cpp file before running gcc.

🧩 “Access denied” or permission errors

Cause: Running commands without admin privileges.
Fix:

• Run Command Prompt or PowerShell as Administrator.
