Qtcreator : Problem to compile examples

[shenakan]

I installed qtcreator 1.2.1 by downloaded it from the website.

qtdemo works. I can compile my program but the examples doesn't compile :

Running build steps for project tabdialog...

I install qt from ubuntu package... I tried with the package qt creator 1.0.0 it was the same.

Go to the project settings pane and check the shadow build option - you have to point a directory you have the read-write access to.
