@ModalAI could you answer this question?

@hedd apologies as I was OOO for a few days. Feel free to send me an email at andrew.wilkins@ascendengineer.com I would like to better understand what you are attempting to accomplish. It should not matter what VOXL version you are on.

@Chad-Sweet @modaltb what should be the fcu url for the updated mavlink server for mavros connection? Please help me to fix this

Apologies. I actually have the simulator running on ROS1 Melodic.

@modaltb Any suggestion ?

@Alex-Gardner Ok, thanks much for running that. Since it built clean for you, that made it clear that there was something bad about my environment (the whole reason I'm down this rabbit hole!). Anyway, my typical configuration is to ssh into my Linux machine from a W10 box using Cygwin/SSH. Apparently something in the build.sh script doesn't like that; hence my failures. When I build directly through the console of that Linux machine the build completes successfully. Sorry for the confusion, and thanks to all for the responses.

Thank you Alex!
