GMP庫6.0.0不會編譯在Mac OS小牛

Question

我試圖編譯這個示例程序

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


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

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

    return 0; 
} 

，我得到這個錯誤：

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) 

我手動編譯我的主要用這個命令：

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

GMP已經通過MacPorts的安裝：

$port list gmp 
gmp       @6.0.0   devel/gmp 

編譯器的信息：

$clang++ --version 
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn) 
Target: x86_64-apple-darwin13.3.0 
Thread model: posix 

一些更多的信息：

ll /opt/local/lib/libgmp* 
/opt/local/lib/libgmp.10.dylib 
/opt/local/lib/libgmp.a 
/opt/local/lib/libgmp.dylib -> libgmp.10.dylib 
/opt/local/lib/libgmpxx.4.dylib 
/opt/local/lib/libgmpxx.a 
/opt/local/lib/libgmpxx.dylib -> libgmpxx.4.dylib 

和：

ll /opt/local/include/gmp* 
/opt/local/include/gmp.h 
/opt/local/include/gmpxx.h

運行clang++ -L /opt/local/lib -I /opt/local/include -lgmpxx -lgmp main.cpp做的伎倆感謝@牛米。
