I add update the .pro file:

@
QT += core gui webkit

And Know I got another error in 64bits:

I have installed the QtCreators (32bits and 64bits), on my Suse 64bits.

You should be fine with a 64bit Qt Creator for both 32bit and 64bit development.

"gst_" smells of gstreamer. Do you have that installed?

Need to be devel packages?
Well, I will install all possible packages.

Well I could compile on 64bits, on 32bits still getting errors:
