移植wireless tools 到android

1.      从www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html 下载wireless_tools.30.pre8.tar.gz， 此版本支持non-ASCII char in ESSID

 

2.      解压到mydroid/external/wireless-tools目录

 

3.      创建Android.mk，内容如下

LOCAL_PATH:= $(call my-dir)
################## build iwlib ###################
include $(CLEAR_VARS)
LOCAL_SRC_FILES := iwlib.c
LOCAL_CFLAGS += -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wpointer-arith -Wcast-qual -Winline -MMD -fPIC
LOCAL_MODULE:= libiw
LOCAL_STATIC_LIBRARIES := libcutils libc libm
include $(BUILD_STATIC_LIBRARY)
################## build iwconfig ###################
include $(CLEAR_VARS)
LOCAL_SRC_FILES := iwconfig.c
LOCAL_CFLAGS += -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wpointer-arith -Wcast-qual -Winline -MMD -fPIC
LOCAL_MODULE:= iwconfig
LOCAL_STATIC_LIBRARIES := libcutils libc libm libiw
#LOCAL_FORCE_STATIC_EXECUTABLE := true
LOCAL_MODULE_PATH := $(TARGET_OUT_OPTIONAL_EXECUTABLES) # install to system/xbin
#LOCAL_UNSTRIPPED_PATH := $(TARGET_ROOT_OUT_UNSTRIPPED)
#LOCAL_MODULE_TAGS := eng user
include $(BUILD_EXECUTABLE)
################## build iwlist ###################
include $(CLEAR_VARS)
LOCAL_SRC_FILES := iwlist.c iwlib.h
LOCAL_CFLAGS += -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wpointer-arith -Wcast-qual -Winline -MMD -fPIC
LOCAL_MODULE:= iwlist
LOCAL_STATIC_LIBRARIES := libcutils libc libm libiw
#LOCAL_FORCE_STATIC_EXECUTABLE := true
LOCAL_MODULE_PATH := $(TARGET_OUT_OPTIONAL_EXECUTABLES) # install to system/xbin
#LOCAL_UNSTRIPPED_PATH := $(TARGET_ROOT_OUT_UNSTRIPPED)
#LOCAL_MODULE_TAGS := eng user
include $(BUILD_EXECUTABLE)

 

 

4.      修改

将wireless.22.h 更名为wireless.h

修改ifrename.c 增加getline的函数，代码可以从external/genext2fs/genext2fs.c中获得

修改iwlib.h，将#include <net/ethernet.h>改为#include <net/if_ether.h>

 

5.      编译

***首先编译libm***这一点是按照网上其他例子做不成功的关键

$cd mydroid/bionic/libm

$source build/envsetup.sh

$mm

$cd mydroid/external/wireless-tools

$mm

下面是编译成功的输出

但是目前在android使用还有点问题，总说
# iwconfig              
lo        no wireless extensions.

dummy0    no wireless extensions.

rmnet0    no wireless extensions.

rmnet1    no wireless extensions.

rmnet2    no wireless extensions.

usb0      no wireless extensions.

tiwlan0   no wireless extensions.
