我设法在我的 Windows 7（64 位计算机）上成功构建了 GMP 库。我遵循的步骤是：

./configure --enable_cxx --disable-static --enable-shared --prefix="/c/MinGW"
make
make install
make check

所有的测试都成功通过。显然，我已经可以编译和运行 GMP 程序了。但是，当我尝试编译以下程序时：

#include <stdlib.h>
#include <string.h>
#include <stdio.h>
#include <gmp.h>

char *progname;

void print_usage_and_exit ()
{
    fprintf (stderr, "usage: %s -q nnn\n", progname);
    fprintf (stderr, "usage: %s nnn ...\n", progname);
    exit (-1);
}

int main (int argc, char **argv)
{
    mpz_t n;
    int i;

    progname = argv[0];

    if (argc < 2)
        print_usage_and_exit ();

    mpz_init (n);

    if (argc == 3 && strcmp (argv[1], "-q") == 0)
    {
        if (mpz_set_str (n, argv[2], 0) != 0)
            print_usage_and_exit ();
        exit (mpz_probab_prime_p (n, 25) == 0);
    }

    for (i = 1; i < argc; i++)
    {
        int result;
        if (mpz_set_str (n, argv[i], 0) != 0)
            print_usage_and_exit ();
        result = mpz_probab_prime_p (n, 25);
        mpz_out_str (stdout, 10, n);
        if (result == 0)
            puts (" is composite");
        else if (result == 1)
            puts (" is a probable prime");
        else /* result == 2 */
            puts (" is a prime");
    }
    exit (0);
}

使用命令：

gcc -m32 -lgmp main.c

我收到以下错误：

谁能告诉我做错了什么？我已经完成了谷歌搜索，在几个小时后，您可以提供的任何帮助将不胜感激。谢谢！

-l 选项用于将库添加到您的程序中。注意顺序很重要！您应该始终在所有对象之后列出库。

尝试gcc -m32 main.c -lgmp
