Newbie question: Step into function

[Sponsel Carsten (ext)]

Hi :-)

I'm new in debugging with gdb and ddd and I'm facing a problem.

I want to debug a small test programm, written in C++. I want to step into a 
member function of an class-object, which was included and linked from a 
library. When I use "step" or "stepi", the ddd will not open the respective 
source file. Does DDD not find the library? What is the problem? I also tried 
to open the respective source file of the via "Open Source" menu, but it is not 
shown in the dialog. Why? I have changed the search path for source files. By 
the way: the search path for object files is not saved...

I'm using DDD 3.3.1 on AMD x86_64...

Help would be very appreciated...

bye,
Carsten
