在C ++中嵌入Lua [英] Embedding Lua in C++

问题描述

我一直在尝试将lua嵌入到c ++应用程序中，但由于编译器抱怨lua_open，我使用Lua 5.2。

I've been trying to embed lua in a c++ application but to no avail since the compiler complains about "lua_open".I'm using Lua 5.2.

我发现很多文章声称lua_open（）在第五个版本被替换，但没有人提到了什么。

I found alot of articles claiming that lua_open() was replaced in the fifth version but none of them mentioned with what.

这是我想要编译的代码

extern "C" {
#include "../lua/lua.h"
#include "../lua/lualib.h"
#include "../lua/lauxlib.h"
}

int main()
{
    int s=0;

    lua_State *L = lua_open();
    // load the libs
    luaL_openlibs(L);
    luaL_dofile(L,"example.lua");
    printf("\nDone!\n");
    lua_close(L);

    return 0;
}

推荐答案

lua 5.2参考手册中未提及$ c> lua_open 函数>

Indeed, the lua_open function is not mentioned in the lua 5.2 reference manual

A lua_State 是由 lua_newstate 您可以使用 luaL_newstate 从 lauxlib.h

A lua_State is constructed with lua_newstate, and you can use luaL_newstate from lauxlib.h

A更快的方式来获得这样的问题的答案是看看Lua 5.2源代码（我刚刚做）。

A faster way to get the answers to such question is to look into the Lua 5.2 source code (which I just did).
