Re: [ptp-user] Eclipse PTP: OpenMPI Hello World cannot connect to debugger
|
Hi Jakub,
PTP runs the following command when it launches the debugger:
mpirun -np 3 -mca orte_show_resolved_nodenames 1 -display-map <debugger command>
When I try the following command (Open MPI 2.0.1) it crashes:
$ mpirun -np 3 -mca orte_show_resolved_nodenames 1 -display-map echo hi

So it looks like this is a bug in Open MPI. I've opened an issue: https://github.com/open-mpi/ompi/issues/5165

I've created a simple Hello World project that compiles with -g3 option and runs as expected using "Generic OpenMPI Interactive" configuration. When I try to run the debugger using .eclipsesettings/sdm and /usr/bin/gdb I get the error I you can see in the image.
