I am running into a similar problem using Qt 4.2.0 open source and msvc.net.

I tried using the directions on the http://qtnode.net/wiki/Qt4_with_Visual_Studio page and received the NMAKE: U1073 error (don't know how to make 'generators\win32\msvc_dsp.h') when running "qconfigure.bat -msvc.net".

Is the only solution to use the commercial version?
