Hi All,

I have successful created a Qt Designer plugin (customer groupbox) on linux. This plugin I also can successful use in my main window where I do display some customer information(compile and run without any errors).

Now I'm switching over to windows and I'm getting my first trouble with it. Creating the dll and the lib files could be done without any problems. But if I use the created plugin in a main window, I get the follwing errors/warnigs:

Qt Code:

I'm using MSVC 2005 Express, Windows XP, Qt 4.2.3.
Any help on this would be great. Many thanks.
