“未定义的引用"指的是:使用Lua [英] "Undefined reference to" using Lua

问题描述

尝试构建项目时出现错误undefined reference to 'luaL_newstate'.我知道链接器有错误，但是对于Lua来说我是比较陌生的人，并且向项目中添加了一个库.我顺便使用Code :: Blocks. API函数luaL_openlibs，luaL_loadfile，lua_pcall，lua_getfield，lua_type，lua_settop也丢失了.

I got the error undefined reference to 'luaL_newstate' when I try to build my project. I know it's an error with the linker but I'm relatively new to Lua and adding a library to a project. I use Code::Blocks by the way. API functions luaL_openlibs, luaL_loadfile, lua_pcall, lua_getfield, lua_type, lua_settop are missing too.

我在一个网站上看到我必须将我的项目与libdl链接才能解决此问题，但是我真的不知道它的含义和用法.

I saw on a webite that I have to link my project with libdl in order to solve this problem, but I don't really know what it mean and how to do it.

推荐答案

我遇到了同样的问题，就我而言，我找到了一个对我有用的解决方案中，例如:

I faced the same problem, in my case I found a solution that worked for me here. Basically consist in wrapping the #include s of lua inside a extern "C", like:

extern "C"{
    #include <lua5.2/lualib.h>
    #include <lua5.2/lauxlib.h>
    #include <lua5.2/lua.h>
}
