    You'll need to post the full error message.

    The linker (ld) complained about something, usually a missing library.

    If your program does not require phonon then don't tell Qt to link it as your PRO file does now. Most of these:
    Qt Code:
    1. QT += network opengl sql script scripttools svg webkit xml xmlpatterns phonon multimedia qt3support testlib dbus
    To copy to clipboard, switch view to plain text mode 
    are not needed for your program, only:
    Qt Code:
    1. QT += sql
    To copy to clipboard, switch view to plain text mode
