移植wireless tool到Android， /bin/sh:xx(命令) not found 問題的解決方案

/system/bin/sh: iwpriv: not found 問題解決方案
代碼下載地址

在使用iwpriv命令時，遇到了 /system/bin/sh: iwpriv: not found 報錯，如何去手機/system/bin目錄下查找，果然沒有這個命令，像ifconfig logcat adbd這些都是有的。所以手機需要安裝 wireless-tools 工具。
1、首先下載代碼：代碼下載地址
代碼下載後解壓並放到手機源碼external/wireless-tools路徑下。

2、添加Android.mk

3、直接單編wireless-tool mmm external/wireless-tools/

我的代碼是經過自己修改的，把報錯都解決了，直接編譯成功。如果有錯誤，可以在不影響其他代碼的前提下把錯誤代碼註釋掉。

4、編譯成功後生成的文件在路徑system/xbin/下

可以看到 其中就有 iwpriv 文件，還有一些其他常用命令，比如 tcpdump、iwlist 等待。直接把相應的文件push到手機 system/xbin 目錄下，手機就可以用這些命令了。
