compiling c++ programs with NTL library

[Jakiro]

Hi, does anyone know how to compile c++ programs that uses the NTL library( http://www.shoup.net/ntl )?

I have installed the package ntl-devel by using yum.
Now I have a simple c++ program that uses NTL:

#include <NTL/ZZ.h>

NTL_CLIENT

int main()
{
   ZZ a, b, c; 

   cin >> a; 
   cin >> b; 
   c = (a+1)*(b+1);
   cout << c << "\n";

   return 0
}

How do I compile this program with g++?
The usual

g++ example.cpp -o example

does not work.
