I think the issue is with my version of GDB.
I updated GCC to 4.8.1 and so it seems I need to update GDB manually
as well now. I will try that and let you know.

Hi Greg,
I seem to have the same problem when using GDB from the command
line:
am12530@logti-a3460-17:~/workspace/mpi-cpp-pi-test/Debug$ gdb
mpi-cpp-pi-test

So I suppose it is not an issue with Eclipse or PTP then? Or could
it be an issue with the build? Here are some more information with
my Debug configuration:
Target System Configuration: Generic OpenMPI Interactive
Connection Type: Local
Number of processes: 2

I would be interested to see what it says at this point.

This is the name of
the local machine, I am trying to debug locally. I had
to uncomment a line from my hosts file in order for it
to work (127.0.1.1 logti-a3460-17).
The MPI Pi C++ example was making the debugger hang as
well, but that is because I had spaces in the directory
name of the project, so I think in the commands the
--routing_file option was not right. Now with a brand
new MPI Pi C++ project I can have the debugger working,
and here is a screenshot similar to yours showing my
issue with the variables.

Is logti-a3460-17 a valid host name on
your system? The sdm is trying to resolve this as an
address but it is failing. This resolution needs to
work on the nodes as well as the frontend, so the node
would need to be configured to resolve the name
correctly.

Thank
you. I have applied the patch, but I just
get a similar error, with gethostbyname
instead of getaddrinfo.

HTH,

Yes it is
Ubuntu... Sorry I don't know how
to apply the patch, what should I
do?

Valentin,
Is your backend Ubuntu by
any chance? I have a
suspicion that getaddrinfo
is buggy on Ubuntu, and this
may be causing the problem.
If you’re feeling
adventurous, you could try
applying the following patch
to the sdm which replaces
getaddrinfo with
gethostbyname. It would be
interesting to see if this
helps at all.

Hi
Greg,
Thanks for your
help. I was using
Open MPI 1.8.1 and
PTP 8.0.1 (with the
fix for OMPI 1.8,
which was working
since the debugger
could launch). I
have now updated to
PTP 8.1.0 and for
some reason I get
the getaddrinfo
error again, the
same way it was
described by
Christoph Schober in
a previous thread
(progress bar
stuck, cannot
connect to debugger,
Eclipse hangs until
SDM process is
killed).
This is slightly
unrelated to my
original problem but
now I cannot start
debugging anymore,
and I don't
understand why I
have this issue
again. I made sure
the start_job.pl
script was correct,
and I recompiled SDM
from the 8.1.0
source archive.
Some SDM debug
output:

The second one

Same for when

I have tried

problem
persists. I am
using Luna
