Thanks for the tips. -DENABLY_DYNDRIVERS=OFF solved the problem. I also tried to compile the sources with MinGW but got "the procedure entry point _Z13qFlagLocationPKc could not be located in the dynamic link library QtCore4.dll" error at the same place where nmake failed. If I have understood correctly, this shouldn't happen because I only have one Qt version installed, but if you have an idea why this happens, please enlighten me.
Also, for some reason the qt_example only works when I build it in debug mode. Is this normal? If I run the release build, I get "Debug error! QWidget: Must construct a QApplication before a QPaintDevice" error. I did a little googling and found out that people have encountered this problem when porting Qt code from another platform, so could this be the problem here, too?
