cpp files in cocos2dx report error.. 囧

why cpp files in cocos2dx folder referenced by my project report error(3.jpg)…
i created this project by D:2d-x-2.1.5\tools\project-creator\project-creator.py
before i open the cpp file , there’s no such errors, and i can build and run it.

what a surprise is that when i import project under samples folder, there is no such problem (1.jpg)…
