John,

thanks for the answer.

Yes, however

No, I don't that's why I'm asking this question. I can attach via cmd
line to the wing debug process and
debug it as manual suggests.

Actually traceback I attached appears if only try to run gdb via OS
Commands tool without running any debug session. But yes, I want to
attach to wing existing debug process.

Thanks, I know that.

:) I understand, the question is not a request for C/C++ debuggin
support in wing - all I want for now is to automate gdb --attach
<running_wing_debug_process_pid> and use OS Commands console for it(if
it's possible), but at minimum I want to automate debug process pid
substitution + env setup(LD_LIBRARY_PATH, gdb source path substitution,
etc.).
