Cocos2d-x android 编译错误 undefined reference to 'MenuScene::getInstance()'

原因：没有找到对应的MenuScene.cpp文件。

虽然文件在../../Classes文 件夹里面，但是在Android.mk里面../../Classes只是头文件的搜索路径，没有放到编译的文件里面。所以这里在链接的时候找不到对应的源文件。

解决方案：修改Android.mk文件LOCAL_SRC_FILES，将

LOCAL_SRC_FILES := hellocpp/main.cpp \
../../Classes/AppDelegate.cpp \
../../Classes/HelloWorldScene.cpp

改成

LOCAL_SRC_FILES := hellocpp/main.cpp \
../../Classes/AppDelegate.cpp \
../../Classes/HelloWorldScene.cpp \
../../Classes/MenuScene.cpp \

../../Classes/StartScene.cpp \

../../Classes/TopMenu.cpp \ ../../Classes/GameLayer.cpp \ ../../Classes/GameScene.cpp \ ../../Classes/WelcomeLayer.cpp \ ../../Classes/WelcomeScene.cpp \ ../../Classes/GameData.cpp \
