    Because in main.cpp You don't include header file with MainWindow definition. I think that this is ui_mainwindow.h file.
    This is not Qt problem but basis of C++.

    The problem is that the class in mainwindow.h is called "Mainmenu", not "MainWindow"

    Given that it is called "MainWindow" in mainwindow.cpp, my suggestion would be to fix mainwindow.h
