编译并构建android 4.1设备的“iw”？

Question

我需要在android 4.1设备上安装iw无线包。但我不知道如何以及要安装的软件包的版本是什么！

也是它需要linux平台来做到这一点，或者它是足够建立和安装在adb外壳为android生根装置。

我看到这个 link，但是当我从adb终端做到这一点时，我看到了那个git和一些没有找到的shell？怎么做 ？

好像没人有什么想法？

在构建iw 3.11版本（已经有Android.mk文件）的同时，由于丢失/错误的头文件和库，我遇到了一些问题。由于它具有Android.mk文件，因此可以使用NDK。

在下面我将承担如下：

• 的设备，像以前（至少应该是可用的内核头文件和libnl-2静态库）建成。我为i9300构建了CyanogenMod 10（内核3.0.something），更新了下面的路径以反映这一点。
• NDK安装到~/android/system/ndk。
• NDK安装了适当的平台和工具链。

  ln -s . jni 
  ln -nsv ~/android/system/external ./ 
  

  下一个问题就是网络链路库：

  In file included from external/libnl-headers/netlink/genl/genl.h:15:0, 
         from /tmp/and/iw/jni/iw.c:17: 
  external/libnl-headers/netlink/netlink.h:27:29: fatal error: linux/genetlink.h: No such file or directory. 
  

  只需在创建一个链接到android/system/out/target/product/i9300/obj/KERNEL_OBJ/usr/include/linux中断其它头严重提取iw-3.11.tar.xz和改变我的目录之后

准备会出现如下错误：

一种解决方法是创建linux目录，并把一个符号链接~/android/system/out/target/product/i9300/obj/KERNEL_OBJ/usr/include/linux/genetlink.h它：

mkdir -p linux 
ln -svn ~/android/system/out/target/product/i9300/obj/KERNEL_OBJ/usr/include/linux/genetlink.h linux/ 

最后修补Android.mk完成连接到网络链路库：

sed "/LOCAL_LDFLAGS/s#\$# -L$HOME/android/system/out/target/product/i9300/obj/STATIC_LIBRARIES/libnl_2_intermediates -lnl_2#" -i Android.mk 

现在构建可开始：

NDK_PROJECT_PATH=$PWD ~/android/system/ndk/ndk-build TARGET_PLATFORM=android-14 

它不会完成，因为netlink /genl/genl.h找不到，但二进制文件在libs/armeabi中可用！
