Debug with QNX MomenticsIDE

When I want to debug a C (or C++) program
I create a launch configuration.
In the Debugger tab, the default debugger is “QNX GDB Debugger”.
When I keep this choice, debuging doesn’t work:
“Exception occured while launching configuration.See log for more information.
Reason:Failed Launching CDI Debugger:Not Supported - this should not ever be called!”
Where is this log file?

When I select “GDB Debbuger” it woks fine.
So what is “QNX GDB Debugger” usefull for? why doesn’t it work?

Thanks.

Update to 6.2.1B and I belive this will go away. It’s a bug.
