wireless_tools在android上的移植

硬件平台：mx53_qsb开发板

软件平台：android2.2.1

 

第一步：网上下载wireless_tools源码包，放在/external目录，并解压，这里使用wireless_tools.29.tar.gz

可从下面的网址下载：

http://bbs.9tripod.com/viewthread.php?tid=126&extra=page%3D1

 

第二步：解压该文件，在external目录中将会新生成wireless_tools.29目录

 

第三步：在wireless_tools.29目录下创建Android.mk文件，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)

 

第四步：源代码修改

1.将wireless.22.h 更名为wireless.h

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

3.修改iwlib.h，将#include 改为#include

4.在iwlib.h中，将下面的代码移出#ifndef IW_EV_LCP_PK_LEN  ......   #endif宏，确保下面的代码生效，否则将提示编译找不到这些宏定义的错误：

struct iw_pk_event

{

__u16 len; /* Real lenght of this stuff */

__u16 cmd; /* Wireless IOCTL */

union iwreq_data u; /* IOCTL fixed payload */

} __attribute__ ((packed));

struct iw_pk_point

{

  void __user *pointer; /* Pointer to the data  (in user space) */

  __u16 length; /* number of fields or size in bytes */

  __u16 flags; /* Optional params */

} __attribute__ ((packed));

 

#define IW_EV_LCP_PK2_LEN (sizeof(struct iw_pk_event) - sizeof(union iwreq_data))

#define IW_EV_POINT_PK2_LEN (IW_EV_LCP_PK2_LEN + sizeof(struct iw_pk_point) - IW_EV_POINT_OFF)

事实上，我们只用将#endif挪在这段代码的上面即可。

 

第五步：在android源码包根目录下，分别执行如下代码编译文件：

source build/envsetup.sh

mm bionic/libm PRODUCT-imx53_loco-eng

mm external/wireless_tools.29/ PRODUCT-imx53_loco-eng

编译完成，将会在out/target/product/imx53_loco/system/xbin下生成iwlist,iwconfig等无线工具。

 

第六步：使用adb push或者重新下载system.img映像文件，就可以正常使用wireless_tools了。
