Android.mk 中的 LOCAL_SRC_FILES, LOCAL_C_INCLUDES

我在先前的两篇post  
[编写Android.mk中的LOCAL\_SRC\_FILES的终极技巧][Android.mk_LOCAL_SRC_FILES]

[编写 android.mk 中 LOCAL\_C\_INCLUDES 的技巧][android.mk _ LOCAL_C_INCLUDES]

中提到了一些编译android.mk文件的技巧, 由于都涉及到了shell命令, 导致不能完全在windows下工作, 下面我使用纯净的makefile语法重新编写了脚本

# 配置自己的源文件目录和源文件后缀名
    MY_FILES_PATH  :=  $(LOCAL_PATH) \
                       $(LOCAL_PATH)/../../Classes
    
    MY_FILES_SUFFIX := %.cpp %.c
    
    # 递归遍历目录下的所有的文件
    rwildcard=$(wildcard $1$2) $(foreach d,$(wildcard $1*),$(call rwildcard,$d/,$2))
    
    # 获取相应的源文件
    MY_ALL_FILES := $(foreach src_path,$(MY_FILES_PATH), $(call rwildcard,$(src_path),*.*) ) 
    MY_ALL_FILES := $(MY_ALL_FILES:$(MY_CPP_PATH)/./%=$(MY_CPP_PATH)%)
    MY_SRC_LIST  := $(filter $(MY_FILES_SUFFIX),$(MY_ALL_FILES)) 
    MY_SRC_LIST  := $(MY_SRC_LIST:$(LOCAL_PATH)/%=%)
    
    # 去除字串的重复单词
    define uniq =
      $(eval seen :=)
      $(foreach _,$1,$(if $(filter $_,${seen}),,$(eval seen += $_)))
      ${seen}
    endef
    
    # 递归遍历获取所有目录
    MY_ALL_DIRS := $(dir $(foreach src_path,$(MY_FILES_PATH), $(call rwildcard,$(src_path),*/) ) )
    MY_ALL_DIRS := $(call uniq,$(MY_ALL_DIRS))
    
    # 赋值给NDK编译系统
    LOCAL_SRC_FILES  := $(MY_SRC_LIST)
    LOCAL_C_INCLUDES := $(MY_ALL_DIRS)

完全使用makefile语法编写, 可以工作在所有平台上

我已经在cocos2d-x中提交了一个pull request [https://github.com/cocos2d/cocos2d-x/pull/3921][https_github.com_cocos2d_cocos2d-x_pull_3921], 希望能被集成到cocos2d-x的代码库中, 以后使用就不需要自己修改了
