Can you confirm that you have compiled with C++ support? If you run
'laminfo' you should see the line:
C++ bindings: yes
Also make sure you included <mpi.h> in the header. Something like the
following should get rid of the warnings at least:
----------------------
#include <iostream>
#include <fstream>
#include <iomanip>
#include <mpi.h>
using namespace std;
int main() { ... }
------------------
Let me know if that helps any,
Josh
