Can anyone tell me how to fix these issues? Thanks!

Could you show your code for the DTLoginLayer.h file?

Compile time error you don’t understand?

Find a line number or start commenting out everything systematically.

#5

Have you reimplemented functions mentioned in your error log (i.e. didAccelerate(…) or ccTouchBegan(…) ) in your source files? If so you also need to add their declaration to header files - this is different from Objective-C where you could just reimplement parent class methods without adding their declarations to header files.

Thanks everyone, problem is resolved.
Nothing wrong with my code. This error is caused by multiple Inheritance, the Inheritance order is important.

change
class CC_DLL CCLayer : public CCNode, public CCTouchDelegate, public CCKeypadDelegate, public CCAccelerometerDelegate
to
class CC_DLL CCLayer : public CCTouchDelegate, public CCKeypadDelegate, public CCAccelerometerDelegate, public CCNode

done!
