How does attaching to a process work?

How does attaching to a process work?

[Laurent Duperval]

Hi,

I've got a Tcl application running that I want to debug. The application is
tkrat, which adds an extension and loads it at run time. I want to attach to
a running tkrat process. So I go to the attach window and I select the
process. It also looks like I have to specify the wish interpreter that was
used to start the process. Now, the wish interpreter wasn't compiled with
debugging on but the tkrat extension was. I'm pretty sure the problem I'm
encountering is in the tkrat extension so I don't want to recompile wish.

Anyway, when I attach to the running wish process, gdb interrupts. THen I
click on the run button and a new wish process is started. Although the
original tkrat process was halted when I attached, it is no longer affected
once the run button on insight has been pressed. Any idea why this is
happening? Am i not doing it right?

Thanks,

L

Don't press the Run button after attaching to the process. You should
be able to set breakpoints and hit continue after attaching.

The continue button is inactive. And whenI attach to the process, it halts
until I press the Run button (which is the only active one).
