Hi philwinder,

I think you are using open souce edition of qt. Please try to build these projects using qt with Visual Studio Integration. It reduces a lot of your work.
You don't need to specify the libraries and all other stuff.
I also got errors while using SDK functions in qt classes in my other project.

So my suggestion is to try with Visual Studio first.

Meanwhile If I will get a chance then I will try to run these projects.

Best Regards,
Sandip
