    Did you properly implement both these functions ? Do you build the corresponding cpp file ?

            When adding/removing the Q_OBJECT macro, do you re-run qmake before building ?

                it says to me that the moc_inpluginimp.cpp file isn't found..
                but the file is in the build directory of the project in the debuge directory

                      #ifndef INPLUGININTERFACE_H and #pragma once - it is the same thinks.
                      You not need #ifndef INPLUGININTERFACE_H if you have #pragma once
                      Sorry for offtop
