after many electricStormBrainShock.... the solution was :
add this line to .bashrc
"LD_LIBRARY_PATH=/home/lucas/lib/:/lib/:/usr/lib/"
and compile with
"mpiCC comunicador.cpp test_comm.cpp -o ejec"
thank for u support.

This is a warning that you should be using <iostream>, not <iostream.h>
(this is unrelated to MPI).

This does not look like a problem with MPI; it looks like you are not
compiling / linking all of your code properly. Your e-mail says that
you have test_comm.cpp, communicador.c, and communicador.h, but I don't
see communicador.c -- where these symbols are defined -- referenced in
your compile/link command ("mpiCC test_comm.cpp -o ejec").
I think you need to compile and link in communicador.c (there are
several different ways that you can do this). See a local programming
guru and/or system administrator for help about this.
Hope this helps.
