sr71, I am also getting same linker error. My setup is VS2005 + Qt 4.6.2 (precompiled libs that Qt provides)

I don't think -no-webkit is an issue.

I found that if I remove Q_OBJECT from .h file the application compiles ok. Also I exported the project to .pro and compiling it in Qt Creator also works fine (this is with Q_OBJECT) in .h file. I don't think that removing Q_OBJECT is a solution to this issue. Anybody???
