树莓派 ubuntu 18.04 64位 arm Linux 裸机编译paddlelite ndk是按照wiki里面curl来 的

输入的命令是这样的 ./lite/tools/build.sh --arm_os=android --arm_abi=armv8 --arm_lang=gcc --android_stl=c++_static full_publish 报错是这样的，输入ndk-build的时候报错是ERROR: Unknown host CPU architecture: aarch64

  The CMAKE_CXX_COMPILER:

    /opt/android-ndk-r17c/toolchains/aarch64-linux-android-4.9/prebuilt/linux-x86/bin/aarch64-linux-android-g++

  is not a full path to an existing compiler tool.

  Tell CMake where to find the compiler by setting either the environment
  variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
  to the compiler, or to the compiler name if it is in the PATH.


CMake Error at CMakeLists.txt:31 (project):
  The CMAKE_C_COMPILER:

    /opt/android-ndk-r17c/toolchains/aarch64-linux-android-4.9/prebuilt/linux-x86/bin/aarch64-linux-android-gcc

  is not a full path to an existing compiler tool.

  Tell CMake where to find the compiler by setting either the environment
  variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
  the compiler, or to the compiler name if it is in the PATH.

另外我想问一下，我是要编译树莓派里面的arm Linux，为啥要安装Android的东西？？我操作有问题吗？？因为我很多东西不理解
