I installed the latest version of Eclipse (3.4.0, it seems it's called Ganymede or something).
I installed the CDT and I can successfully build and debug simple C++ applications.
Then I installed the QT Integration provided by Trolltech. However after the installation nothing changes. I read that with version 3.4 they changed the plugin system, and I found this http://dev.eclipse.org/newslists/new.../msg76221.html for linux but I don't understand how to get the problem settled on windows.
