eclipse cocos2dx项目，出现错误

[plain] view
plaincopyprint?

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

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ndk编译需要将每个cpp进行声明

进入jni-->Classes目录下的Android.mk

[plain] view
plaincopyprint?

LOCAL_SRC_FILES := AppDelegate.cpp \

HelloWorldScene.cpp

修改成

如下：

[plain] view
plaincopyprint?

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
