I just replied on the other thread.

ok i looked at the errors closely, it looks like that the problem is
from the "namespace MPI{.." in line 136 of "mpicxx.h" and every

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.
