Build DJI Guidance SDK ROS pkg for ARM64 architecture (Jetson Nano)

edit

Hello, I have installed ROS on Jetson Nano following the instructions given at https://github.com/jetsonhacks/instal... Running DJI on board SDK works fine although i cant build Guidance SDK on ARM64. Up to this point, i needed to install arm-linux-gnueabi-g++ compiler in order to recognize libDJI_guidance.so. I also needed to cross compile opencv3. Right now i'm facing the following error when building guidance pkg.
