Do you want to be able to compile C, C++, Ada and Fortran programs on Windows without losing time wrestling with a bulk, resource-intensive IDE? You can! The solution is to port the ultra-popular, lightweight GCC (GNU Compiler Collection) often used in *nix systems to Windows via MinGW + Cygwin.

MinGW is the minimalist GNU implementation for Windows.

1. Install Cygwin, which provides many Linux commands/libraries to Windows

2. Install MinGW

3. Make sure that MinGW was added to your PATH by typing PATH in a terminal

If not, you can add it through Window’s GUI interface (just type PATH or Environment in Start on Win 7 or 8 and it will come right up as a search result).

4. In a terminal (cmd or PowerShell) go to the directory containing the code you want to compile, i.e.

5. Type the compile command:

g++ hackr.c -o hackr.exe

where -o is indicating your output file.

This also works with compiling multiple files:

g++ hackr.c econometrics.c hadoop.c overflow.c -o hackeconometrics.exe

This should take at least an hour or 2 less time than installing Microsoft’s Visual Studio (though the latter has it’s virtues) or a similar bulky IDE and will give you fewer headaches by avoiding complicating your life with a million unnecessary options and confusing attempts to “help” you build a simple project.
