[mpich-discuss] gdb + hydra

[Christoph Sprenger]

still trying to get this to work.
i've also tried a vanilla tcsh and bash with no env set at all and both 
seem to fail still.

same things persists when running mpiexec -n 1 gdb without xterm

Ubuntu 10.04.4 LTS
GNU bash, version 4.1.5(1)-release
tcsh 6.17.00 (Astron)


mpich2
./configure --enable-shared --enable-sharedlibs=gcc




#include "mpi.h"
#include <iostream>

int main(int argc, char *argv[])
{
     MPI_Init(&argc, &argv);
     int rank,size;
     MPI_Comm_size( MPI_COMM_WORLD, &size );
     MPI_Comm_rank( MPI_COMM_WORLD, &rank );
     std::cerr << "Hello World from rank " << rank << " / " << size << 
std::endl;
     MPI_Finalize();
}

[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/libthread_db.so.1".

is there anything else i can try to make this work ( eg different 
configure options for hydra or mpich2 ) ?

Cheers,
Christoph
