error LNK2001: unresolved external symbol "public: static struct QMetaObject

[d_stranz]

I think this error typically occurs because MOC hasn't run to generate its moc_*.cpp files, or if it has, the .cpp files have not been compiled or the resulting .obj files have not been included in the link. Try doing a clean rebuild. Also make sure that you have declared Q_OBJECT in and classes that inherit from QObject.

You could also look at your .vcproj file. You should see entries such as this:
