Qt Creator fail to compile !

[qt_chan]

I've just install Qt Creator 1.3.1 from this Qt website
http://qt.nokia.com/downloads/qt-cre...ry-for-windows
I'm using Windows 7 64 bit. I followed the Qt Creator Manual to create a GUI application, however; it did not compiled successfully. I got these error messages from the compiler output:

And I have no idea what's wrong ! Anyone could give me a hint that where did I miss ? Thank you !

It looks like your Qt is not configured with QtDBus module.
This project needs the DBus modules to run.

Thanks high_flyer ! Can you show me how to configure QtDBus module ? I'm very newbie with GUI programming !

Where did you take this example from?

[qt_chan]

Example is the name of my project. I've just created a "Qt4 Gui Application" and click compiled button( which looked like a "play" button ). I did not modify anything from the code that given by Qt Creator.
I have 1 header file named "mainwindow.h" and 2 source files named "mainwindow.cpp" and "main.cpp" plus a mainwindow.ui.

Go to your *.pro file and delete dbus out ot the QT variable. Then rerun qmake and build again.

[qt_chan]

Thanks Lykurg ! It worked perfectly. And would you mind explaining why do I have to delete that "dbus" out of the QT variable ?

[Lykurg]

The right question is: Why do you have put it there if you don't need it? With the QT variable you define which (Qt-)libraries Qt should link against your application. So if you don't need a library or if you don't have such a library don't write it there.

Thanks for making it clear.
