Thanks. This explains it.

I compiled from commandline, this succeeeded.
After doing so compiling in kdevelop was successful also.

Unfortunately these experiments needed 3 hours ;-)

The userinterface in digikam is incredibly good, so I could concentrate 
on the number crunching code for the plugin, that is what I want to do.

Unfortunately this doesnt work for me.

I set a breakpoint in the plugin code.
Then I start the program (F9).

The program stops at breakpoint.
Then I see a green triangle at the breakpoint location.

and when I press F11 (singlestep) the program steps on.
(I am doing this while writing)
Ok... I stepped until the next breakpoint.

Now this beakpoint is grayed out and the digikam app is dead (no response)

The debug menu gives me the options to suspend the app or to halt it.
But so far I can see, it doesnt run.
Suspending does nothing, no change. Halt will abort digikam, it dies.

I can see the local variables for my procedure, but so far I can see, 
the execution point is elsewhere and the programm is not running, maybe 
it hangs on another breakpoint, but how can I find it?

I got all my software from debian's testing and unstable repositories.

Possibly my kdevelop is buggy, possibly I should try to write a hello 
world program first and try to debug it.. Unfortunately 
kdevelop-GUI-debugging is not so very well documented, I must try how it 
works.

Yes I know. But in advance I must write some code to produce some memory 
leaks. It's an easy task for me, I am rather good with this *g*

thanks so far,
