cocos2d-x游戏引擎在每新建一个工程时都会附带好多库文件要编译，导致开发效率降低，一个helloworld项目初次编译可能都要10来分钟。
所以减少编译时间是非常有必要的。 (本文只讲VS2013和AndroID NDK的方法，其他平台大同小异)
有一个参考 http://blog.csdn.net/etring/article/details/8608032但他的还不够。
我用的是cocos2d-x-3.x 一共有30来个静态库，17个要源码编译，所以做了大量改进更通用一些。
1.新建一个项目HelloCocos2dx: cocos.py new HelloCocos2dx -p com.longshu -l cpp ，有300多M。进入proj.androID目录执行ndk-build或者build_native.py。
如果是androID-studio，在proj.androID-studio\app\jni下执行ndk-build命令。 (建议使用COCOS_ROOT/tests/cpp-empty-test空项目,免去新建项目 *** 作)
2.成功后在proj.androID\obj\local\下会默认生成armeabi平台所需要的各种静态库，其他平台在proj.androID\jni\Application.mk文件添加即可
比如APP_ABI := armeabi armeabi-v7a x86生成3个平台的静态库。(两个平台第一次编译大概占880M)
3.在COCOS_ROOT(游戏引擎安装目录)下新建一个prebuild文件夹，在prebuild下新建androID，androID下新建armeabi armeabi-v7a x86（根据自己要的平台）,
复制第2步proj.androID\obj\local下的相应平台到prebuild下的相应平台目录，一共17个*.a文件(大概210M，libcocos2dcpp.so不要)。复制好后记得 ndk-build clean 。
4.再prebuild/androID文件夹下面新建一个AndroID.mk，内容在文章最后面。该文件是根据COCOS_ROOT/cocos/AndroID.mk修改而来。
5. 修改proj.androID/AndroID.mk 内容如下：
LOCAL_PATH := $(call my-dir)#Cocos2d-x安装目录,如果环境变量有可以不配COCOS_ROOT := D:/Dev_Tool/Cocos2d-xinclude $(CLEAR_VARS)#去除#$(call import-add-path,$(LOCAL_PATH)/../../cocos2d)#$(call import-add-path,$(LOCAL_PATH)/../../cocos2d/external)#$(call import-add-path,$(LOCAL_PATH)/../../cocos2d/cocos)#要添加 不然import-module找不到编译好的静态库$(call import-add-path,$(COCOS_ROOT))LOCAL_MODulE := cocos2dcpp_sharedLOCAL_MODulE_filename := libcocos2dcppLOCAL_SRC_fileS := hellocpp/main.cpp \ ../../Classes/AppDelegate.cpp \ ../../Classes/HelloWorldScene.cppLOCAL_C_INCLUDES := $(LOCAL_PATH)/../../Classes# _COCOS_header_ANDROID_BEGIN# _COCOS_header_ANDROID_ENDLOCAL_STATIC_liBRARIES := cocos2dx_static# _COCOS_liB_ANDROID_BEGIN# _COCOS_liB_ANDROID_ENDinclude $(BUILD_SHARED_liBRARY)#去除#$(call import-module,.)# 保存了编译好的静态库目录$(call import-module,prebuild/androID)# _COCOS_liB_import_ANDROID_BEGIN# _COCOS_liB_import_ANDROID_END
这里新加了两句:
$(call import-add-path,$(COCOS_ROOT))
$(call import-module,prebuild/androID)
去除了原来的import-add-path和import-module 。
这样就可以在修改了Classes下的代码和java代码时，在几十秒内完成编译了。以后新建项目只要修改第5步的AndroID.mk文件就OK了。
而且还可以删除(建议不要，VS或者其他开发工具要用到)cocos2d下的extensions目录和cocos下除platform以外的目录(platform里面还有一个引用项目)。效果如下：
安卓编译效果：
============================================================================================
下面介绍VS2013减少编译时间的方法 和安卓的方法不同1.打开COCOS_ROOT/build/cocos2d-win32.sln也可以使用上面的HelloCocos2dx,主要是为了方便调试。选择libcocos2d项目，DeBUG模式，右键->生成，漫长等待后，
在build\DeBUG.win32目录下会有大量的*.lib和*.dll库文件生成(其实好多是来自Cocos已经编译好的复制过来的)，一共有45个文件。
2.在COCOS_ROOT(游戏引擎安装目录)下新建一个prebuild文件夹，在prebuild下新建win32文件夹(最好在下面新建Release和DeBUG区分编译版本)，复制第1步的lib到win32下的DeBUG和复制dll文件到win32下。
3.修改项目配置: 选择HelloCocos2dx解决方案->右键->属性->通用属性-项目依赖 右边选择HelloCocos2dx项目-去除小面的勾。
选择解决方案下HelloCocos2dx(你的项目)右键->属性->通用属性-引用 移除中间的引用。如下图：
4. 在HelloCocos2dx(你的项目)属性->配置属性->上面选择所有配置->VC++目录 $(Configuration)表示Release和DeBUG
对于添加 $(COCOS_ROOT)\prebuild\win32和$(COCOS_ROOT)\prebuild\win32$(Configuration) 如下图：
5.选择HelloCocos2dx(你的项目，不要选择libcocos2d项目了否则又要编译好久)，右键-生成-运行 ，是不是飞一般的快呢！？
到这里可以选择libcocos2d项目，右键清理。
存在问题:EXE程序在加载动态库dll文件时会在当期目录和系统path环境变量里找，所以还要把在系统path后面添加 ;%COCOS_ROOT%\prebuild\win32
否则会出现dll文件没找到的错误。
运行效果:
