external "hello world"

Hi,

I'm having problems embedding external C++ functions.
I tried a simple hello_world-predicate like this:

C++-Source:
---------
#include <iostream.h>
#include "eclipseclass.h"

int p_hello(void)
{
  cout << "Hello World!" << endl;
  return EC_succeed;
}

Compiling:
-------
g++ -I<eclipse-dir>/include/i386_linux -shared -o hello_ecl.so 
hello_world.cc

Eclipse-User-File: (ecl_hello.pl)
---------------------
:- load("hello_ecl.so").           

:- external(hello/0,
                           "p_hello").

calling: eclipse -b  ecl_hello.pl gives me the following error:

ELF file's phentsize not the expected size
general error in load("hello_ecl.so")

*** compilation aborted
   before line 2 in the file /home/strack/prologtest/ecl_hello.pl

Does anyone know what this error means and what I did wrong?
