Mesa was originally designed for Unix/X11 systems and is still best supported on those systems. All you need is an ANSI C compiler and the X development environment to use Mesa. Others have contributed drivers for the Amiga, Apple Macintosh, BeOS, NeXT, OS/2, MS-DOS, VMS, Windows 9x/NT, and Direct3D. See the README file included with the Mesa distribution for more details.
