Problem of debugging a program inside another c++ program [message #1768904]

Hi all,

I have a c++ program in NS3 called "sctpNetworkExample" which has network configuration (connection of server and client ) and also I have an application layer program which executes in sctpNetworkExample (as dce) which is called "sctpApproach" (it opens sessions, send and receive packets).
When I open and debug sctpNetworkExample, it debugs line by line till the line that sctpApproach should execute, then sctpApproach runs without I can trace it. I mean it runs but there is not any control in the debugger for it. I wish to debug the other one also.
I would greatly appreciate if you can guide me.
Thanks in advance

Not sure I 100% follow. But if I have understood correctly you want to debug forked programs?

If so, have a look at https://sourceware.org/gdb/onlinedocs/gdb/Forks.html for a starting point.

Thanks for your guide.
What i got of your suggested page was the setting for gdb to solve the problem. Now my question is that, could I do these settings for gdb in Eclipse? I see that there is a debugger tab in debug configuration or options for gdb in preferences but it seems my required setting has to be done somewhere else of Eclipse).Could you please guide me?

Create a gdbinit file that contains any extra commands you want to issue to GDB and in the Launch configuration point at that file.

Remember that some settings may cause GDB and Eclipse to not communicate as expected, so some experimentation will be needed.

If you have a good combination of commands that suits your needs, and it is likely to be generally useful, we can add those commands to default CDT, perhaps with just a check-box in the Launch configuration. If so, please file an enhancement request: https://bugs.eclipse.org/bugs/enter_bug.cgi?product=CDT
