移植wireless tools (iwpriv, iwconfig, iwgetid, iwevents, iwspy, iwlist)到Android

最近在调试WIFI softap功能，发现netd源码中包含"iwpriv"相关的注释，这个工具应该会对WIFI调试非常有用，于是准备将其移植到Android上。

首先到这里下载源码，然后解压，按照网上搜出来的方法，把目录里头Makefile的CC，AR等改成交叉编译所用的，但是发现make all的时候报缺少头文件错误。用-I将头文件引入之后在ld阶段又报缺少crt0.o。折腾了半天之后依然无果，于是决定直接在目录下加个Android.mk用Android的make来编译。

一次尝试之后竟然成功了，泪流满面，以下是具体步骤：

1，在目录下cp -f wirless.29.h wirelss.h （自带的Makefile就是这么干的，根据版本选择头文件，我下载的是.29版本）

2，在目录下加入Android.mk，内容如下：

LOCAL_PATH := $(call my-dir)
ifneq ($(TARGET_SIMULATOR),true)

include $(CLEAR_VARS)

LOCAL_MODULE := libiw

LOCAL_MODULE_TAGS := eng

LOCAL_SRC_FILES := iwlib.c

LOCAL_C_INCLUDE += LOCAL_PATH

#LOCAL_SHARED_LIBRARIES := libiw
LOCAL_PRELINK_MODULE := false

include $(BUILD_SHARED_LIBRARY)

endif # !TARGET_SIMULATOR

3，在目录下mm，将生成的libiw.so用adb push到/system/lib，其他的iwxxx push到/system/bin。

PS： 有用自带的Makefile编译成功的同学请指点一下啊。
