Errors:

@mainwindow.obj:-1: error: LNK2005: main already defined in main.obj
debug\uwm.exe:-1: error: LNK1169: one or more multiply defined symbols found@

You have main program routines as the error message suggests. There is only one allowed in C++. Either eliminate main.cpp or mainwindow.cpp from your project.

go to the project in your case "uwm" with the mouse and press right mouse button. Select "Run qmake" and rebuild afterwards.

This line tells you that the file, which you have eliminated, is missing. Which is certainly, but it is still in your setup. Since the .pro file looks correct, Qt creator has not redone the makefiles, which you do manually with the sequence above.

SOLVED ... Thanks
