DJGPP

Another option in the realm of open source C++ development tools is DJGPP, which is a command-line tool that is designed to work on several different platforms, including Windows. Because it is a command-line tool, DJGPP is a little trickier to install and use than a graphical environment, but it comes with straightforward directions that really aren't too tough to follow. The biggest challenge to using DJGPP is setting up projects for your programs so that they compile in a single step. Again, the documentation for DJGPP will help you along in this task.
