1. Download MinGW packages (see below)
2. GCC 4.2.1 set (commended) or GCC 4.5.2 set
3. Extract them into one same folder in order, for example C:\MinGW
4. Download MSYS packages (see below)
5. Extract them into one same folder in order, for example C:\MSYS
6. Download Libraries (optional, see below)
7. Extrat them into the MinGW folder, for example C:\MinGW
8. Create a file named “fstab” in C:\MSYS\etc, with the necessary content “C:/MinGW /mingw”
9. Create a shortcut of C:\MSYS\msys.bat for convenience

Now by clicking the shortcut of C:\MSYS\msys.bat, you could enter the MSYS environment.
