Hello All! I am attempting to run the GroundSDK on a raspberry pi 4 (8GB) running Ubuntu 64:
Static hostname: team1-Hub
Icon name: computer
Operating System: Ubuntu 22.04.1 LTS
Kernel: Linux 5.15.0-1017-raspi
Now I know the issue already you may be thinking is that its an ARM64, for that I installed Box64 emulator. I know this isn’t fool proof but i hoped it would work. I followed these instructions for Box64 AMD64 Emulator: Run x64 Software on a Raspberry Pi using Box64 - Pi My Life Up
I then followed this Ground SDK installation guide: Install and build GroundSdk - 7.3
Now for the NDK I can not install the lib86 libraries as I am on an arm cpu and not even the emulator can trick that. (Is it possible if I go to Ubuntu 32bit and install a 32bit emulator box86? I don’t think so but maybe) so I skipped installing lib86.
I got down to “Build GroundSDK” running command:
./build.sh -p groundsdk-android -t build -j

Stop. [E] Command failed (returncode=2)
Mainly it seems the issue is this: cannot access ‘/opt/out/groundsdk-android/armeabi-v7a/toolchain/bin/*-objdump’: No such file or directory.
I read that a github SDK pull for my specific NDK might work (I installed NDK Revision 17c per instructions on linked page) but I have found no solution.
WHAT ARE YOU TRYING TO DO?!:
I am trying to install a groundsdk or any SDK to a raspberry pi 4 that will act as a central hub to send GPS coordinates to the AIR SDK of a parrot anafi. I saw that Olympe does not have this feature though it could be installed.
Now if this is not possible at all. I am going to attach a raspberry pi 0 W with the airSDK on the parrot. I will then send the gps coordinates via zigbee protocol (from a PC with an AMD64 processor I suppose instead of a pi 4) to the pi 0 W (assume this works) the pi 0 w will then transmit the coordinates directly to the drone via airsdk (Idk if this part is possible). This is my work around. In the end I hope to do this for three of these parrots we have to make a mesh network swarm.
I’m not new to python or coding but I am new to this scale of things and any and every bit of expertise from the community would be helpful
