Problem running QtCreator on LinuSuse 11.4

Please if you’re reading help i really need your help any kind of information would help.
When i try to compile i get this error:
Error while building project clocks (target: Desktop)
When executing build step ‘Make’

and this:
Failure to open file: /opt/QtSDK/Examples/4.7/declarative/toys/clocks/Makefile
Unable to generate makefile for: /opt/QtSDK/Examples/4.7/declarative/toys/clocks/
The process “/opt/QtSDK/Desktop/Qt/473/gcc/bin/qmake” exited with code 5.

I also find every Makefile generated in my home directory.

Thanks in advance!
