cheers! thx for explanation - yeah sounds damn easy ;) the reason i asked for crosscompile is that i simply wiped out my old morphos installation with gg: and didn't have the time to set it up back again. last time i checked the usdx sources at least the libc unit was missing for ppc systems in fpc - no idea if usdx still requires it. and yes, portaudio would be a problem indeed :) ffmpeg should be optional though i think.
