Just remove that line. It shouldn't be there in the first place, it has no use. In fact, move the actual definition from radiobuttons.cpp to mainwindow.cpp for consistency. Why declare a MainWindow member in a different implementation file? share|improve this answer answered Dec 30 '12 at 22:38 Luchian Grigore 167k28295455 if I remove that line from mainwindow.cpp, i get :mainwindow.obj:-1: error: LNK2019: unresolved external symbol "public: void __thiscall MainWindow::build_radios(
