Don't you use the "-lgmpxx" parameter for your compiler ?
The documentation tells us to use it:
http://www.swox.com/gmp/manual/Headers-and-Libraries.html#Headers%20and%20Libraries

Example:
#include <iostream>
#include <gmpxx.h>

void main ()
{
   mpz_class tt1, tt2, tt3;

   tt1 = "20923928392892";
   tt2 = "9823092839";
   tt3 = tt1*tt2;
   cout << tt3 << endl;
}
