Embedding Lua in C++

Question

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.

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

Here's the code I am trying to compile

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;
}

Answer 1

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

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

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