Cocos2d-x 避免手工输入项目需要编译的cpp文件到Android.mk里

手工输入项目需要编译的cpp文件到Android.mk里的缺点

1）繁琐，如果cpp文件很多，简直无法忍受

2）手工输入过程中容易出现错误

3）如果cpp文件更改名称，需要修改Android.mk文件

。。。。等等

 <span style="font-family:SimHei;font-size:18px;">LOCAL_PATH := $(call my-dir)

 include $(CLEAR_VARS)

 LOCAL_MODULE := game_shared

 #traverse all the directory and subdirectory
 define walk
   $(wildcard $(1)) $(foreach e, $(wildcard $(1)/*), $(call walk, $(e)))
 endef

 #traverse Classes Directory
 ALLFILES = $(call walk, $(LOCAL_PATH)/../../Classes)

 FILE_LIST := hellocpp/main.cpp
 FILE_LIST += $(filter %.cpp, $(ALLFILES))

 FILE_INCLUDES := $(shell find $(LOCAL_PATH)/../../Classes -type d)

 #source file will be compiled
 LOCAL_SRC_FILES := $(FILE_LIST:$(LOCAL_PATH)/%=%)


 LOCAL_C_INCLUDES := $(LOCAL_PATH)/../../../external/Box2D/ \
     $(FILE_INCLUDES) \



 LOCAL_WHOLE_STATIC_LIBRARIES := cocos2dx_static cocosdenshion_static cocos_extension_static box2d_static

 include $(BUILD_SHARED_LIBRARY)
