    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
