Yep, I get the same thing. Are you using Qt Creator or another IDE? I too am running on Windows.
I get these errors when I run your code:

I use qt qreator 3.0.1. What can i do for them?

https://qt-project.org/doc/qtcreator-3.1/creator-quick-tour.html
Check out number 7, that's where you can see all the different output panes. I clicked on application output and saw the errors.
