編譯並構建android 4.1設備的「iw」？

Question

我需要在android 4.1設備上安裝iw無線包。但我不知道如何以及要安裝的軟件包的版本是什麼！

也是它需要linux平臺來做到這一點，或者它是足夠建立和安裝在adb外殼爲android生根裝置。

我看到這個 link，但是當我從adb終端做到這一點時，我看到了那個git和一些沒有找到的shell？怎麼做 ？

好像沒人有什麼想法？

在構建iw 3.11版本（已經有Android.mk文件）的同時，由於丟失/錯誤的頭文件和庫，我遇到了一些問題。由於它具有Android.mk文件，因此可以使用NDK。

在下面我將承擔如下：

• 的設備，像以前（至少應該是可用的內核頭文件和libnl-2靜態庫）建成。我爲i9300構建了CyanogenMod 10（內核3.0.something），更新了下面的路徑以反映這一點。
• NDK安裝到~/android/system/ndk。
• NDK安裝了適當的平臺和工具鏈。

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

  下一個問題就是網絡鏈路庫：

  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. 
  

  只需在創建一個鏈接到android/system/out/target/product/i9300/obj/KERNEL_OBJ/usr/include/linux中斷其它頭嚴重提取iw-3.11.tar.xz和改變我的目錄之後

準備會出現如下錯誤：

make: *** [/tmp/and/iw/obj/local/armeabi/objs/iw/iw.o] Error 1 

一種解決方法是創建linux目錄，並把一個符號鏈接~/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/ 

最後修補Android.mk完成連接到網絡鏈路庫：

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

現在構建可開始：

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

它不會完成，因爲netlink /genl/genl.h找不到，但二進制文件在libs/armeabi中可用！
