Remote Debugging [message #1691]

Hi,

apologies if I am not posting in the correct forum.

I am using eclipse 3.2.1 with CDT 3.1.1 and RSE SDK 1.0RC4
I am running on a windows XP and my remote target is a Linux Suse 9.3.

I can setup targets to the linux box and check the processes running there
and create shells. I can do it this with both ssh and dstore.
I can run my application on the target without problems when I hit the run
button.
The problem I have is with debugging when I launch the debugger it starts
a new process with gdbserver on the remote target and starts listening on
port 2345. see below:
----------------------------------------
sh

/home/uklvasg>
gdbserver :2345 /usr/rhp/eclipse/vision/VisionTest;exit
Process /usr/rhp/eclipse/vision/VisionTest created; pid = 15931
Listening on port 2345
/home/uklvasg>
Remote debugging from host 130.141.105.235
---------------------------------------

After 2 seconds I get an error message box saying
Target selection failed
Target is not responding (timed out)

I have tried to increase the wait time of the debugger but no difference.
I also checked that the process and gdb are running fine on the target
waiting for commands on the port 2345.

I have now run out of ideas and don't know how to get it working.
I would appreciate any help.

Thanks
George

Hi George,

could it be that a firewall prevents access to port 2345 from the
outside? - I'd recommend testing the setup with gdb on the commandline,
if you can do that:

Remote side -> gdbserver :2345 /your/app
Local side -> gdb /your/app,
then on the (gdb) prompt enter
target remote remote.host.com:2345

If this doesn't help, I'd recommend filing a bugzilla report
for further investigation, this will increase visibility and
help making answers/responses trackable.

Thanks,

Hi,

I actually have it working now. The problem was with the version of gdb I
was using not supporting cross-debugging. I downloaded and build a
cross-debugging version and now everything works fine.

Thanks for your help it was very easy to identify the problem from the
command line once I tried to run the debugger outside eclipse.
