To install MinGW, follow these steps:
-
Download MinGW:
- Go to the MinGW website: MinGW — Minimalist GNU for Windows.
- Look for the "Downloads" section and download the installer appropriate for your system (32-bit or 64-bit).
-
Run the Installer:
- Execute the installer you downloaded.
- Follow the installation instructions.
- During installation, you’ll be prompted to select components. Make sure to include the C++ compiler (usually named mingw32-gcc-g++).
-
Add MinGW to System Path (Optional but recommended):
- After installation, add the MinGW bin directory to your system's PATH environment variable. This step allows you to run the compiler from any command prompt.
- For example, if MinGW is installed in C:\MinGW, add C:\MinGW\bin to your PATH.
After completing these steps, you should be able to compile C++ programs using MinGW. Here's an example of how to compile a C++ program:
-
Create a C++ file: Save the file with a .cpp extension, such as hello.cpp. You can use any text editor to create this file.
-
Compile the C++ file: Open a command prompt and navigate to the directory where your hello.cpp file is saved. Then, run the following command to compile the program:
g++ hello.cpp -o hello.exe -
Run the compiled program: After successful compilation, you can run the compiled executable by typing its name in the command prompt:
hello.exe
That's it! You've installed MinGW and compiled a simple C++ program.
