Did you also add "PKGCONFIG += hildon-1" or whatever the commandline in the Makefile would be as you said in your first post?
Do you have a main function? (the first error)
What is your "TEMPLATE" when using qmake? lib, app?
Do you compile using QtCreator or the MADDE commandline? (Very important!)

You can also take a look at this example project of the bug report:
