Question

嘿大家我发现这个代码将Lua嵌入C中我无法弄清楚如何让GCC编译它。我安装了Lua，但是如何链接Lua库？

以下是我找到的代码：

            #include <stdio.h>
            #include "lua.h"
            #include "lualib.h"
            #include "lauxlib.h"

            /* lua interpreter */
            lua_State* l;

            int main () {
            int dofile;

            /* initialize lua */
            l = lua_open();

            /* load lua libraries */
            luaL_openlibs(l);

            /* run the hello.lua script */
            dofile = luaL_dofile(l, "hello.lua");

            if (dofile == 0) {
            /* call foo */
            lua_getglobal(l,"foo");
            lua_call(l,0,0);
            }
            else {
            printf("Error, unable to run hello.lua\n");
            }

            /* cleanup Lua */
            lua_close(l);

            return 0;
            }

如何编译？

我正在尝试这个命令来编译

gcc -o embed_hello -L/users/etrosclair/Downloads/lua-5.1.4 -I/users/etrosclair/Downloads/lua-5.1.4 luaTest.c

这是错误：

Undefined symbols for architecture x86_64:
  "_luaL_newstate", referenced from:
      _main in ccF0995Q.o

所有lua库和标题都在lua-5.1.4文件夹中.o文件也在那里。

取决于您是否需要静态或动态编译。

对于静态，添加-llua（或lua5.1或lua51;取决于您的设置）

在C中编译嵌入式lua
