Qt metaObject linker problem

Question

After integrating Qt with Vs and trying to compile .pro file I\'m getting following errors:

Error   9   error LNK2001: unresolved external symbol \"public         


        

Answer 1

Some fairly long-winded explanations above.
Using Qt Creator, on the menu bar:
Build>Run qmake
Build>Build All

Answer 2

Same problem occurred when I used Qt Addin for VS, I saw moc files are not included into project after building. I included them into project these errors are gone.
