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_SRC_FILES := iwlib.c

LOCAL_C_INCLUDE += LOCAL_PATH

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。
