This is just the compile output, not the application output (different window in creator). Did you hit F5 or one of the green triangles, or did you hit ctrl-b?

Below is the application output...

Starting /Volumes/abc/Program Files/myapp_src/build_mac/MyApp.app/Contents/MacOS/MyApp...
/Volumes/abc/Program Files/myapp_src/build_mac/MyApp.app/Contents/MacOS/MyApp exited with code 0

Basic question: Are you sure you're calling exec() on your QApplication in your main()?

ya....now i finally figured out that problem...
Thanx all of you for your help.

But now i am getting a different error

1. "2011-08-24 12:00:39.295 MyApp[379:80f] *** __NSAutoreleaseNoPool(): Object 0x6a89090 of class NSCFArray autoreleased with no pool in place - just leaking"

2. "QCocoaView handleTabletEvent: This tablet device is unknown (received no proximity event for it). Discarding event."
