What operating systems does Gnash run on?
Gnash should run on most *NIX systems, although most of the development and testing has been with GNU/Linux, IRIX and BSD derivatives. Gnash will compile on PowerPC- and Intel-based Macs–although not easily–. Windows builds are available (compiled against Mingw). We encourage you to submit reports of your building experiences (please refer to the Gnash manual for instructions).
