我正在尝试编译一个使用 GMP 库中的许多函数的 C 程序 (gfp2.c)。我使用正常的配置、制作和安装顺序下载并安装了 GMP 库。我还在安装前运行了 make check 并且没有错误。

我正在使用 GMP 5.1.1、GCC 4.2.1 和 MAC OS 10.8.2。

我首先键入gcc gfp2.c -lgmp链接库，然后尝试gcc gfp2.c在终端上获取以下输出：

1407-wn-172-21-30-223:pqcrypto11_scripts dfish$ gcc gfp2.c -lgmp 

v1407-wn-172-21-30-223:pqcrypto11_scripts dfish$ gcc gfp2.c

我对 C 编程和使用库等很陌生，真的不知道我在做什么，所以任何帮助表示赞赏。谢谢！

您需要在 GMP 库中链接：

gcc gfp2.c -lgmp

（目前尚不清楚为什么你最初让它工作，然后在没有库的情况下重新运行）。

Your first attempt has already done the compilation and the linking. You don't need to do the second step. If you check your directory you'll find a file called a.out that is the executable you need.
