[原创]COCOS2DX 3.8 增加protobuf为external库

此处为记录防止忘记，最近使用COCOS练习一些新的库，所以需要把PROTOBUF编译进去，看上去很麻烦，这里记录一下，以防忘记。

首先下载protobuf 2.5.0版本，下载地址请自行百度。

准备工作：

CYGWIN下载：http://cygwin.com/setup-x86.exe

1、请确保机器中有CYGWIN,并且CYGWIN必须安装好GCC,GDB和MAKE等，文章很多，请自行搜索

2、配置CYGWIN的NDK环境：

打开CYGWIN目录下的home\Administrator\.bash_profile，并在最下面添加内容：

NDK=/cygdrive/J/android-ndk-r10d

export NDK

重启CYGWIN，测试执行：cd $NDK ，此处NDK环境配置完毕

3、确保安装好COCOS2DX最新版

4、曾经使用过PROTOBUF，本文非PROTOBUF教程，为配置引导教程。

编译PROTOBUF ANDROID

解压缩PROTOBUF文件至COCOS目录，注意：为了防止文件混乱建议最好在COCOS根目录下新建名为THRDLIB的目录存放PROTOBUF。

解压后用WINDOWS版本先编译，如果出现MIN和MAX函数错误，只需要在：src\google\protobuf\io 目录下找到 zero_copy_stream_impl_lite.cc 文件，在文件头部增加 INCLUDE：#include <algorithm>，此处BUG修复，请安心兼容ANDROID。

（建议:请先新建一份COCOS的DEMO游戏，并将WINDOWS版本的PROTOBUF放入引用，新建对应的测试协议，确保在WINDOWS一切正常）

编译ANDROID版本步骤：

1、进入PROTOBUF解压所在目录

3、新建文件：Application.mk

内容:

APP_STL := gnustl_static 
APP_CPPFLAGS := -frtti 
APP_ABI := armeabi armeabi-v7a x86

解释：此处ABI为兼容COCOS的3中情况，分别编译3中类型的库，稍后会提供配置方式。

4、新建文件：Android.mk

内容：

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := protobuf_static

LOCAL_MODULE_FILENAME := protobuf

LOCAL_SRC_FILES :=src/google/protobuf/io/coded_stream.cc \
 src/google/protobuf/stubs/common.cc \
 src/google/protobuf/descriptor.cc \
 src/google/protobuf/descriptor.pb.cc \
 src/google/protobuf/descriptor_database.cc \

LOCAL_EXPORT_C_INCLUDES :=
LOCAL_EXPORT_LDLIBS :=

LOCAL_C_INCLUDES := $(LOCAL_PATH) \
$(LOCAL_PATH)/src

LOCAL_LDLIBS := \
-llog \
-lz

include $(BUILD_STATIC_LIBRARY)

5、回到上一级目录，将SRC目录整个拷贝至JNI目录下。

6、打开CYGWIN，进入PROTOBUF目录下（访问WINDOWS目录方法为：cd /cygdrive/f/protobuf）

7、输入：

$NDK/ndk-build

静静的等待安装完毕。

将protobuf安装至external目录

编译完毕protobuf后，我们开始安装对应的文件。

步骤如下（以COCOS2DX 3.8为例）：

1、进入COCOS框架目录下：Cocos\Framework\frameworks\cocos2d-x-3.8\external

2、新建目录protobuf

3、在目录下新建 include 以及 prebuilt 目录，此处开始较为重要

4、将PROTOBUF目录下的src目录下的.h文件拷贝至COCOS框架下的external/protobuf/include目录下（注意COPY完毕后，其相对路径会是：external\protobuf\include\google）。

5、进入external/protobuf/prebuilt,新建目录android（如已经编译好WIN32版本，请直接新建WIN32目录，并COPY lib文件至该目录下）

6、回到PROTOBUF编译目录下的obj\local目录下，拷贝目录下的3个文件夹：armeabi、armeabi-v7a、x86 至COCOS框架目录下的：external/protobuf/prebuilt/android目录下，并记得删除每个目录内的obj文件夹，保留.a文件，别删错噢。

7、在external/protobuf/prebuilt/android目录下新建文件：Android.mk

内容如下：

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE := protobuf_static
LOCAL_MODULE_FILENAME := libprotobuf
LOCAL_SRC_FILES := $(TARGET_ARCH_ABI)/libprotobuf.a
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/../../include
include $(PREBUILT_STATIC_LIBRARY)

8、进入COCOS的cocos2d-x-3.8\cocos\prebuilt-mk目录下打开文件 Android.mk 文件，请务必使用NOTEPAD++或UE等工具打开，否则可能排版混乱

9、修改该文件内容如下：

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := cocos2dx_internal_static

LOCAL_MODULE_FILENAME := libcocos2dxinternal

ifeq ($(USE_ARM_MODE),1)
LOCAL_ARM_MODE := arm
endif

ifeq ($(TARGET_ARCH_ABI),armeabi-v7a)
MATHNEONFILE := math/MathUtil.cpp.neon
else
MATHNEONFILE := math/MathUtil.cpp
endif

LOCAL_SRC_FILES := ..\..\prebuilt\android/$(TARGET_ARCH_ABI)/libcocos2dxinternal.a

$(LOCAL_PATH)/../../external/poly2tri/sweep \
$(LOCAL_PATH)/../../external/clipper


LOCAL_EXPORT_LDLIBS := -lGLESv2 \
                       -llog \
                       -landroid

LOCAL_WHOLE_STATIC_LIBRARIES := cocos_freetype2_static

$(call import-module, protobuf/prebuilt/android)

至此，可以在COCOS STUDIO中尝试编译你的项目至ANDROID，PROTOBUF应该已经在里面了，而且不管新建几个项目，都会自动包含，不用另外配置。

此处额外分享一套自动搜索CPP,C以及CC文件的MK内容，不必挨个增加编译文件噢（适用于大部分COCOS项目，几乎不必修改任何内容，新增CPP也会编译在内，非常方便噢）。
