I have edited the lines 108 and 126 (also with
MPR_debug_state)
and when i launch Eclipse debugger i have now the error :
"Error completing launch
Reason:
Project does not exist or is not a project type"
All is fine to run the program without debug

That may or may not be a problem. Let’s try this first. Can you edit ~/.eclipsesettings/rms/MPICH2/start_debug_job.pl and add ‘(int)’ to the line that prints ‘MPIR_debug_state' (line 108)?
After the change it should read:
$response = $gdb->get("print (int) MPIR_debug_state");
Regards,
Greg

Bruno,
What version of MPICH are you using?
If you run ‘gdb /path/to/mpiexec’ from the command line, then enter the commands:
b main
run
print MPIR_debug_state
what does it say?

Hi Greg,
thank you for your answer.
I just installed Devel:GDB and Expect modules.
But i still have an error :

Hi Bruno,
Sorry it’s taken so long to get back to you!
It looks like the GDB perl module is not installed on your compute nodes, so the start_debug_job.pl perl script is failing. Is it possible to have the module installed?
Regards,
Greg

Hi all,
I want to use eclipse PTP on an existing cmake project. I am using MPICH on Ubuntu 18.04 with Eclipse 2019-06 (4.12.0).
Everything is OK for building and running my program in parallel. But there is an issue for debugging; when I run the debugger, I get the following message :
Can't locate Devel/GDB.pm in @INC (you may need to install the Devel::GDB module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.26.1 /usr/local/share/perl/5.26.1 /usr/lib/x86_64-linux-gnu/perl5/5.26 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.26 /usr/share/perl/5.26 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base) at /home/boeg7312/.eclipsesettings/rms/MPICH2/start_debug_job.pl line 17.
BEGIN failed--compilation aborted at /home/boeg7312/.eclipsesettings/rms/MPICH2/start_debug_job.pl line 17.
For the time being I launch everything locally, on a single machine.
Any help would be appreciated...
Bruno
