LUA 编译错误与 Visual 2010“外部符号"struct lua_State * __cdecl luaL_newstate(void)" [英] LUA compile error with Visual 2010 "external symbol "struct lua_State * __cdecl luaL_newstate(void)"

问题描述

我在 Visual Studio 2010 中使用 Lua ver 5.2.3，当我编译下面的代码时

I use Lua ver 5.2.3 with visual studio 2010 , when i compile code below

#include "stdafx.h"

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

void main()
{
    lua_State *luaState = luaL_newstate();

}

我有错误

error LNK2019: unresolved external symbol "struct lua_State * __cdecl luaL_newstate(void)" (?luaL_newstate@@YAPAUlua_State@@XZ) referenced in function _wmain

你能就此给我任何建议吗?谢谢！！！

Could you please give me any advice about this . Thank !!!

推荐答案

这是 C++名称修改"的结果.看看这个词怎么会有奇怪的字符:

This is a result of C++ "name mangling". See how there are strange characters in this term:

?luaL_newstate@@YAPAUlua_State@@XZ

你有选择:

将此文件的文件扩展名更改为 .c 而不是 .cpp，以便它通过 C 编译器而不是 C++ 编译器运行(注意:取决于编译器)

Change the file extension of this file to .c instead of .cpp, so that it runs through the C compiler instead of the C++ compiler (caveat: depending on compiler)

或

在包含的周围添加 extern "C"，如下所示:

Add extern "C" around the includes like this:

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

或

#include "lua.hpp"

在最后一种情况下，该头文件包含在 5.2 版本中.它执行我在选项 2 中为您编写的内容.

In the last case, that header is included with the 5.2 release. It does what I wrote in option 2 for you.
