bibliothèque GMP 6.0.0 ne compile pas sur Mac OS Mavericks

Question

Je suis en train de compiler cet exemple programme

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


int main(int argc, const char * argv[]) 
{ 

    mpz_class rho = 3; 
    std:cout << rho; 

    return 0; 
} 

et je reçois cette erreur:

Undefined symbols for architecture x86_64: 
    "___gmpz_clear", referenced from: 
     __gmp_expr<__mpz_struct [1], __mpz_struct [1]>::~__gmp_expr() in main-5858d5.o 
    "___gmpz_init_set_si", referenced from: 
     __gmp_expr<__mpz_struct [1], __mpz_struct [1]>::init_si(long) in main-5858d5.o 
ld: symbol(s) not found for architecture x86_64 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 

compiler mon principal manuellement cette commande:

clang++ -L /opt/local/lib -I /opt/local/include -lgmpxx main.cpp

et:

ll /opt/local/include/gmp*

Courir clang++ -L /opt/local/lib -I /opt/local/include -lgmpxx -lgmp main.cpp fait le tour grâce @ N.m.
