Subject: [OMPI users] Problem with feupdateenv

Hello all,

Installed Open MPI 1.2.8 with Intel C++compilers on Cent OS 4.5 based
Rocks 4.3 linux cluster (& Voltaire infiniband). Installation was

The following error occurred during compilation:

# mpicc hellompi.c -o hellompi
/opt/intel/cce/10.1.018/lib/ warning: warning: feupdateenv
is not implemented and will always fail

It produced the executable. But during execution it failed with
Segmentation fault:

# mpirun -np 2 ./hellompi

object, consider re-linking

mpirun noticed that job rank 0 with PID 17781 on node master exited on
signal 11 (Segmentation fault).
1 additional process aborted (not shown)

But this is not the case, during non-mpi c code compilation or execution.

# icc sample.c -o sample
# ./sample

Compiler is working

What might be the reason for this & how it can be resolved?
