嗨，我想将 protobufs 添加到我的项目中。到目前为止，我只尝试使用 android 并且到目前为止还没有幸运。

我已将我的库：libprotobuf.a、libprotobuf-lite.a、libprotoc.a 放在“Protobuf”文件夹中，就在可以找到“Classes”文件夹的位置。我生成了一个名为“Msg.pb.cc”的 Proto 并将其放在 Classes 文件夹中。我已将 Protobuf .h 文件放在类文件夹中。即类/google/protobuf/....

这就是我的 Android.mk 现在的样子。

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE    := libprotoc
LOCAL_SRC_FILES := ../../Protobuf/libprotoc.a
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE    := libprotobuf-lite
LOCAL_SRC_FILES := ../../Protobuf/libprotobuf-lite.a
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE    := libprotobuf.a
LOCAL_SRC_FILES := ../../Protobuf/libprotobuf.a
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)

LOCAL_MODULE := cocos2dcpp_shared

LOCAL_MODULE_FILENAME := libcocos2dcpp

LOCAL_CPP_EXTENSION := .cxx .cpp .cc

LOCAL_SRC_FILES += hellocpp/main.cpp \
               ../../Classes/AppDelegate.cpp \
               ../../Classes/GameSprite.cpp \
               ../../Classes/GameLayer.cpp \
               ../../Classes/Control.cpp \
               ../../Classes/HelloWorldScene.cpp \
               ../../Classes/NativeInterface.cpp \
               ../../Classes/Msg.pb.cc 


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

LOCAL_WHOLE_STATIC_LIBRARIES += cocos2dx_static
LOCAL_WHOLE_STATIC_LIBRARIES += cocosdenshion_static
LOCAL_WHOLE_STATIC_LIBRARIES += box2d_static
LOCAL_WHOLE_STATIC_LIBRARIES += chipmunk_static

include $(BUILD_SHARED_LIBRARY)


$(call import-module,cocos2dx)
$(call import-module,cocos2dx/platform/third_party/android/prebuilt/libcurl)
$(call import-module,CocosDenshion/android)
$(call import-module,extensions)
$(call import-module,external/Box2D)
$(call import-module,external/chipmunk)

一旦编译 Msg.pb.cc，我就会收到很多错误。这里有几个：

不知何故，我猜这些文件没有链接。代码找不到 protobuf 库。我不知道 Android.mk 文件是如何编写的，并且对 cpp 也没有太多经验。这只是一些谷歌搜索和阅读原始 Android.mk 文件的结果。任何帮助表示赞赏。

-cocos2dx-2.2.5
-eclipse+ADT。
-sdk 5.0.1
-ndk r8e
