The Cygwin project is a collection of the most common tools and compilers (including the bash shell and the GNU compiler chain) for Windows. When it comes to compiling and running programs written for Linux on Windows, there is a solution known as Cygwin. Although there are many different cross-platform libraries and SDKs, native programs written without portability in mind are quite hard to port. Windows and Linux are two very different systems, and as such, it often isn’t easy to port programs written for one to the other, especially when dealing with GUI programs.
