Build Guidance SDK pkg for ARM64 architecture (Jetson Nano) #48
Description
Hello, I have installed ROS on Jetson Nano following the instructions given at https://github.com/jetsonhacks/installROS 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.

Do I need to crosscompile ROS and the dependencies from source?
If that's the case can anyone provide me with some brief instructions.
Thank you.
