G:/AndroidCocos2dxFile/android-ndk-r8e/toolchains/arm-linux-androideabi-4.6/prebuilt/windows-x86_64/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld.exe: ./obj/local/armeabi/objs/game_shared/__/__/Classes/AppDelegate.o: in function AppDelegate::applicationDidFinishLaunching():jni/../../Classes/AppDelegate.cpp:29: error: undefined reference to 'StartLayer::scene()'

make: *** [obj/local/armeabi/libgame.so] Error 1

<2>解决方案。

这个问题困扰了我快一天，因为以前运行别人的工程是没有问题的，还以为没有加上main.h和main.cpp导致的。

解决问题的方法就是，在Android.mk中：

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

在后面加上要编译的.cpp文件文件

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := game_shared

LOCAL_MODULE_FILENAME := libgame

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

LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes

LOCAL_WHOLE_STATIC_LIBRARIES := cocos2dx_static cocosdenshion_static cocos_extension_static

include $(BUILD_SHARED_LIBRARY)

$(call import-module,CocosDenshion/android) \
$(call import-module,cocos2dx) \
$(call import-module,extensions)

搞定！！！

然而最佳解决方案是用下面的Android.mk文件，什么都不用加，就OK了，不管里面有.cpp文件多少编译了。

LOCAL_PATH:=$(callmy-dir)
