<4>cd 到 frameworks/cocos2d-x/tools/tolua下面，运行./genbindings.py生成绑定文件

<5>xcode下：

1,

cocos2d_lua_bindings.xcodeproj下的auto文件夹里面添加生成的.hpp和.cpp文件

2,

Classes下添加导出的.hpp 和 .cpp文件及其对应的.h 和 .cpp文件

3,

TARGETS Mac下:

header Search Paths中添加搜索路径：

<span >$(SRCROOT)/../../../../../runtime-src/Classes</span>

<6>cocos code IDe 下：

local function main()    collectgarbage("collect")    -- avoID memory leak    collectgarbage("setpause",100)    collectgarbage("setstepmul",5000)    cc.fileUtils:getInstance():addSearchPath("src")    cc.fileUtils:getInstance():addSearchPath("res")    cc.Director:getInstance():getopenGLVIEw():setDesignResolutionSize(480,320,0)    local var = cc.CustomClass:create():helloMsg()    print(var)    --create scene    local scene = require("GameScene")    local gameScene = scene.create()    gameScene:playBgMusic()    if cc.Director:getInstance():getRunningScene() then        cc.Director:getInstance():replaceScene(gameScene)    else        cc.Director:getInstance():runWithScene(gameScene)    endend
