Compiling a C++ program with gmpxx.h

[emarti19]

I was able to build GMP no problem on by i686, Mandrake 8.1 DE PC.
When I built the libraries, I used "./configure --enable-cxx". I ran both 
"make" and "make install", no problem, and "make check" worked fine. When I 
compile the program:

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

void main() { }

It runs with no problems, which means it can include the headers fine. 
However, when I do the simpliest operation, it gives me an error. In the 
program:

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

int main ()
{
        mpz_class a;
        return 0;
}

G++ (the compilier I am using) prints the following when I try it compile:

address@hidden programming]$ g++ test.cpp
/tmp/ccqhPZVJ.o: In function `__gmp_expr<__gmpz_value, 
__gmpz_value>::__gmp_expr(void)':
/tmp/ccqhPZVJ.o(.__gmp_expr<__gmpz_value, 
__gmpz_value>::gnu.linkonce.t.(void)+0xe): undefined reference to 
`__gmpz_init'
/tmp/ccqhPZVJ.o: In function `__gmp_expr<__gmpz_value,

collect2: ld returned 1 exit status

Do I need different arguments when I run "./configure"? What do you recommend?
