Re: [cdt-dev] Re: Interaction between perspectives.
|
Ramesh,
We are working on the mixed Java/JNI debugger supporting currently
Java and C/C++ languages. It is being integrated into Eclipse IDE
under the Debug perspective. Currently, we are able to set and stop on
line breakpoints in both Java and C/C++ code. Depending on what stack
frame is active, we are able to watch Java and native data -
variables, their values. It works in the ordinary debug perspective.
Probably, (two or more) separate percpectives for each debug-info
representation might be introduced, but at this moment there are no
well-defined vision of this.

Ramesh -
many thanks for your request. There are some initiatives in the area of
debugger inter-communications, but none is really mature yet.
One problem is that when an event in debugger A should initiate some
action in debugger B, you'd typically want to do this with very low
latency. Which requires a solution sitting "very close to the target",
which typically means vendor-specific non-standard (read: non-eclipse)
solutions.
If low latency this is not a requirement, some Eclipse UI based event
handling could be the right solution. We thought that the Target
Management Project might be the Umbrella defining such events, to be
understood by many debuggers that want to communicate. An empty
discussion page is available under "Inter-Debugger Communications" from
http://wiki.eclipse.org/index.php/DSDP/TM
I'm not sure how far the Device Debugging Project has already progressed
to support inter-debugger communications.
Another initiative I know of, is a Java/JNI/gdb debugger integration
being investigated by intel. You might be able to meet these folks on
the CDT groups.
I'm copying the dsdp-tm-dev, dsdp-dd-dev and cdt-dev mailing lists with
this answer. If there is any developer that can help you further, please
chime in.
Thanks
Martin
