You shouldn't need to add any -I's or -L's or -l's for Open MPI. Just
use mpic++ and mpicc (per my first note, notice that "mpicc" (lower
case) is the C compiler -- mpiCC is a synonym for the C++ compiler --
this could be your problem). Those wrappers add all the compiler /
linker flags that you need.

The openmpi is installed in the following path: /opt/openmpi/1.2.7
so should i replce what you told me about /usr/lib with /opt/openmpi/
1.2.7 ??

I don't quite understand the format of this file, but at first glance,
you shouldn't need the following lines:
export LIBMPI = -lmpi
export MPIDIR=/nfs/sjafer/phd/openMPI/installed
export LDFLAGS +=-L$(MPIDIR)/lib
export INCLUDES_CPP += -I$(MPIDIR)/include
It also doesn't seem like the last 2 arguments of this line are a good
idea (the linker should automatically put /usr/lib and /lib in your
search path, if appropriate):
export LDFLAGS+=-L. -L$/usr/lib -L$/lib
I also notice:
export CPP=mpic++
export CC=mpiCC
I think you want "mpicc" for CC (note the lower case) -- mpiCC is the
C
++ compiler (mpic++ and mpiCC are synonyms).
This might solve your problem.
