I don' t know exactly. I deleted the .ui file and paste it again and deleted some folders that were in project directory and after that the project compiled.

If you have the same file in two different locations, Ie: "mainwindow.ui" and "../../../../../IBO_win03_1/mainwindow.ui" listed in your project file it will not compile.
