Question

所以我试图在Codeblocks中编译这段代码：

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

using namespace std;

void
myfunction (mpz_t result, mpz_t param, unsigned long n)
{
  unsigned long  i;

  mpz_mul_ui (result, param, n);
  for (i = 1; i < n; i++)
    mpz_add_ui (result, result, i*7);
}

int
main (void)
{
  mpz_t  r, n;
  mpz_init (r);
  mpz_init_set_str (n, "123456", 0);

  myfunction (r, n, 20L);
  mpz_out_str (stdout, 10, r); printf ("\n");

  return 0;
}

我在编译时遇到此错误

现在我已经在google上调查了这个问题，但我发现这些解决方案似乎没有用。

目前正在Project＆gt;构建选项＆gt;搜索目录＆gt;链接器，我有gmp-6.1.0的位置

我已尝试将gmp放入项目＆gt;构建选项＆gt;链接器设置＆gt;其他链接器选项，但这不起作用，而是给我这个：

-------------- Build: Debug in orcs (compiler: GNU GCC Compiler)---------------

mingw32-g++.exe -L..\..\Lzip\gmp-6.1.0 -L..\..\Lzip\gmp-6.1.0 -o bin\Debug\orcs.exe obj\Debug\main.o  gmp  ..\..\Lzip\mybuilddir\.libs\libgmpxx.a

我不确定问题出在哪里，因为我非常确定所有内容都安装在默认位置。希望这足以帮助我解决问题：）
