Supported Platforms

The developers are regularly testing on the following platforms:

• Ubuntu 10.04 (x86/32, x86/64)
• Windows (x86/32) with Visual C++ Express 2008/2010

Additionally, we believe that the code should be running on these other platforms, but we don't have the resources to test on them regularly:

• recent Linux distributions (x86/32, x86/64)
• Mac OS X (x86, PPC)

People have reported success with Cygwin on Windows, but this is not a tested platform.
If you're interested in supporting other platforms or languages, please get in touch with Ray Smith.
