[Qt-creator] Packages for Linux

[sebastianlaptop at inode.at]

I downlaoded CTCreator from the trolltech homepacke (the 22mb Package or
something) for 32bit.
Which packages do I have to install, so that QTCreator runs without Problems.
I searched in the internet, I installed many packages, but it didn't work.
When I want to compile something he says:

No valid Qt version set. Set one in Tools/Options
Error while building project test
When executing build step 'QMake'
Canceled build.

I also nstalled QDevelop 4.
