Compiling lora_gateway for RPI0W2

HI.
I am trying to compile lora_gateway manually for RPI0W2 Board since the existing gateway image wont work for RPI0W and the Raspberry Pi team already released RPI0W2 which is running by 64bit processor.

I am getting the following error. Any kind of support is appreciated.
