大家好,我发现这段代码将 Lua 嵌入到 C 中,但我不知道如何让 GCC 编译它。我安装了 Lua,但如何链接 Lua 库?
这是我找到的代码:
#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;
}
我如何编译它?
我正在尝试编译这个命令
gcc -o embed_hello -L/users/etrosclair/Downloads/lua-5.1.4 -I/users/etrosclair/Downloads/lua-5.1.4 luaTest.c
这里是错误:
Undefined symbols for architecture x86_64:
"_luaL_newstate", referenced from:
_main in ccF0995Q.o

所有的 lua 库和头文件都在 lua-5.1.4 文件夹中,.o 文件也在那里。
谢谢
谢谢
最佳答案
取决于你是想静态编译还是动态编译。
对于静态,添加 -llua(或 lua5.1 或 lua51;取决于您的设置)
