Hello, I am getting a linker error while compiling the following code:

---
// test the gmp library:

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

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

  a = 1234;
  b = 5678;
  c = a+b;
  std::cout << "sum is " << c;

  return 0;
}
---

The command line options I am using are as follows:

---
C:\test>gpp bignum.cpp -o bignum.exe -lgmp
---

I get this error:

---
c:/djgpp/tmp\ccaIkv3J.o(.gnu.linkonce.t._ZlsRSoRK10__gmp_exprI12__gmpz_valueS1_E
+0x1c):bignum.cpp: undefined reference to `operator<<(std::ostream&,
__mpz_struc
t const*)'

collect2: ld returned 1 exit status
---

Anyone know what may be causing this?  It seems like the linker can't
find the standard library...  Thanks!
