Hi
I have exported the library files as below

[master_at_ip-10-80-106-70 ~]$ export
LD_LIBRARY_PATH=/usr/local/openmpi-1.4.5/lib:$LD_LIBRARY_PATH

[master_at_ip-10-80-106-70 ~]$ mpirun --prefix /usr/local/openmpi-1.4.5 -n 1
--hostfile hostfile out
out: error while loading shared libraries: libmpi_cxx.so.0: cannot open
shared object file: No such file or directory
[master_at_ip-10-80-106-70 ~]$ mpirun --prefix /usr/local/lib/ -n 1 --hostfile
hostfile
out

out: error while loading shared libraries: libmpi_cxx.so.0: cannot open
shared object file: No such file or directory

But still iam getting the same error.
