I found that I have to include q3mainwindow in addition to preprocessor.

I don't have .pro file. I am using Visual studio 2008.
I added QT3_SUPPORT as a preprocessor, but still get the same error.

It did, but you're apparently not building with Qt3Support enabled. Add
QT+=qt3support to your .pro file(s).

Note: qt3to4 is not meant as an automatic conversion tool for Qt3 apps, it just
gives you a starting point by doing some of the easier search/replace stuff
thats needed to make your app compile with qt4.
