移植wireless tool到Android， /bin/sh:xx(命令) not found 问题的解决方案

/system/bin/sh: iwpriv: not found 问题解决方案
代码下载地址

在使用iwpriv命令时，遇到了 /system/bin/sh: iwpriv: not found 报错，如何去手机/system/bin目录下查找，果然没有这个命令，像ifconfig logcat adbd这些都是有的。所以手机需要安装 wireless-tools 工具。
1、首先下载代码：代码下载地址
代码下载后解压并放到手机源码external/wireless-tools路径下。

2、添加Android.mk

3、直接单编wireless-tool mmm external/wireless-tools/

我的代码是经过自己修改的，把报错都解决了，直接编译成功。如果有错误，可以在不影响其他代码的前提下把错误代码注释掉。

4、编译成功后生成的文件在路径system/xbin/下

可以看到 其中就有 iwpriv 文件，还有一些其他常用命令，比如 tcpdump、iwlist 等待。直接把相应的文件push到手机 system/xbin 目录下，手机就可以用这些命令了。
