New Win install, Hello World compile error.

[dougbroadwell]

I have just installed 4.3.4 (from installer, not compiled from source). I cut and pasted the "Hello World" example out of Examples & Demos and get the following errors:

Rename your file to hi.cpp and try again.

I always feel so dumb when I make stupid errors like that.

Now I get the following error:

The Qt debug libs are not compiled - you have to compile them by your own when you install the binary package. If you don't know how to do this -> search function (it was discussed many times here)
