... I did not mention that I am using the msys/mingw combination under windows. When you download the QT creator under windows, it is accompanied with the mingw set.
I can not say I am expert in windows (actually this was my first program ever compiled in a windows environment), so I really have no idea what eats the processor time. Btw I did have quite some trouble with "modern" linux distros as well, the software was originally developed under slackware, no problem whatsoever. When I started using "modern" distros like ubuntu and fedora I found out that the portaudio lib and the pulseaudio soundserver do not particularly like each other, but using the oss emulation of alsa makes it bearable. best jan 2010/1/30 jan van katwijk <[email protected]> > > > 2010/1/30 Stephan Schaa <[email protected]> > >> W7 is even worse than Vista.
