Error on make for not-x64

[shariq-audiofocus]

Thanks for building this project iwatake. I'm trying to build an EdgeTPU CPP example for my Coral Dev board.

I was able to build and run the binary for x86 using your instructions. But when I tried for arm-v8 it failed with the following error:

(base) shariqm@bigsir:~/code/coral/EdgeTPU_CPP/project_classification_tflite/build$ cmake .. -DARCH_TYPE=aarch64 -DUSE_EDGETPU=on
... [success]

I think it's some type of cross-compiling issue but I'm not sure. Any idea? I'm using Ubuntu 18.04 so perhaps that's a problem:

The project is for native build. Please build on Coral Dev Board.

If you want to build on your PC(Ubuntu), you need to install cross compiler for arm and modify cmake (like set(CMAKE_CXX_COMPILER arm-linux-gnueabihf-g++) ).

ah ok thanks, that worked. Cross compiling would be nice since the coral dev board doesn't have much disk space. I'll try your suggestion.
