eclipse cocos2dx项目，出现错误

[plain] view plaincopyprint?

1. E:/Acocos2d-x/cocos2d-1.0.1-x-0.11.0/MyBilliard/android/jni/../../Classes/HelloWorldScene.cpp:27: undefined reference to `GameLayer::GameLayer()'  
2. E:/Acocos2d-x/cocos2d-1.0.1-x-0.11.0/MyBilliard/android/jni/../../Classes/HelloWorldScene.cpp:27: undefined reference to   

原因是android的nkd编译需要将每个cpp尽心进行声明

进入jni-->Classes目录下的Android.mk

[plain] view plaincopyprint?

1. LOCAL_SRC_FILES := AppDelegate.cpp \  
2.                    HelloWorldScene.cpp  

修改成

如下：

[plain] view plaincopyprint?

1. 
   
2. LOCAL_MODULE_FILENAME := libcocos2dcpp
   
   
   MY_CPP_LIST := $(wildcard $(LOCAL_PATH)/*.cpp)
   MY_CPP_LIST += $(wildcard $(LOCAL_PATH)/hellocpp/*.cpp)
   MY_CPP_LIST += $(wildcard $(LOCAL_PATH)/../../Classes/*.cpp)
   
   
   LOCAL_SRC_FILES := $(MY_CPP_LIST:$(LOCAL_PATH)/%=%)
   
   
   
   
   LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes
