Hi ,

I have project made in QT 4.7.
Now i see that QT 5 is released and have installed it.
I noticed that a lot of clases has changed.A lot of them now are in QtWidgets/ i changed my code in accordance with this change.
Now i have only one problem before run my code.

The error:

I didn't change nothing in the mainwindow.ui file neither in mainwindow.

Porting C++ Applications to Qt 5 (http://qt-project.org/doc/qt-5.0/qtdoc/portingcppapp.html)

Step 2 is what you need.

#include <ui_mainwindow.h>
#include <info.h>

You shouldnt be using angle brackets for these includes

Thanks a lot.
Adding QT += widgets did the trick :)

If you do the includes without the module path part then the same include can be used for Qt4 and Qt5, e.g.

#include <QMainWindow>

Cheers,
