[SOLVED] QT Creator won't Run any of examples

Hi I just installed QT SDK, and at startup it recommends me to see some of "Demos and Examples" and I did so, I tried 4-5 examples and EVERY have some errors. Most of them look like this:

Re: [SOLVED] QT Creator won't Run any of examples

Your code obviously links to libpng12, which isn't in the default repo. It's in the AUR, so try installing it from there.

Re: [SOLVED] QT Creator won't Run any of examples

/me suggests just using qt from repos + a sane editor instead. Or atleast build qtcreator from source (you can find it in aur)

U saying I can programme qt apps without QT Creator, just with sane (or some other) editor?
