Hello Andrew Plenty compile on Windows: Some OpenVG, OpenGL[1] (still? - I'm a bit behind the times) only compile with MinGW. Others are fine with Cygwin provided you have the dev packages installed (readline, pcre-light...). Yet others - no chance... If you can get the raw C library to work in either Cygwin or MinGW, you should have a good chance. The only sound software I've had working on Cygwin has been ChucK though I haven't tried many - ChucK uses RtAudio to talk to the soundcard which probably isn't easy to write a binding for as its C++. I had ChucK working two years ago, maybe things have improved in the Cygwin world regarding sound since then and other systems now work. http://www.music.mcgill.ca/~gary/rtaudio/ Best wishes Stephen [1] OpenGL worked fine when it was bundled with GHC, when it got unbundled things seemed to go amiss, plus it seemed to be the thing to use freeglut - hence the complicated instructions here: http://netsuperbrain.com/blog/posts/freeglut-windows-hopengl-hglut/
