Question

所以我一直在编写一个c ++程序，在它里面它处理的内核对于内置的long long来说太大了。没问题，我只使用一个bignum库。所以我得到GMP，说出这三个魔术命令＆＃34; ./ configure，make，make install＆＃34;并开始使用它。我使用c ++程序文档中指定的#include "gmpxx.h"。编译它，GPP在gmpxx.h中发现一个错误，因为很明显gmp.h不能使用角度定位，而且应该在gmpxx.h的include语句中使用引号。然而，在将角度更改为引号后，我很惊讶地发现出现了问题，我认为这样做会使得＆＃39;。它说：

Undefined symbols for architecture x86_64:
  "___gmpz_clear", referenced from:
      __gmp_expr<__mpz_struct [1], __mpz_struct [1]>::~__gmp_expr() in primality-3fd487.o
  "___gmpz_cmp_si", referenced from:

    ld: symbol(s) not found for architecture x86_64
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

有谁知道如何阻止这些错误发生？

使用gmp时定位库时出错
