嵌入式lua运行时错误：未找到符号：_luaL_newstate

我的代码

inline int DOFILE(string& filename) {

  printf("lua_open\n");
  /* 初始化 Lua */
  lua_State* L = lua_open();

  printf("lua_openlibs\n");
  /* 加载 Lua 基本库 */
  luaL_openlibs(L);

  printf("lua_dofile\n");
  /* 运行脚本 */
  int ret = luaL_dofile(L, filename.c_str());

  printf("lua_close\n");
  /* 清理 Lua */
  lua_close(L);

  return ret;
}

编译选项：

obj.cxxflags = ["-g", "-D_FILE_OFFSET_BITS=64", "-D_LARGEFILE_SOURCE", "-Wall", "-llua-5.1"]

也尝试了 '-llua' 和 '-llualib'，所有的都报告了警告：

i686-apple-darwin11-llvm-g++-4.2: -llua-5.1: linker input file unused because linking not done

当我运行时，它报告：
