ArduSub build for Navio2

Is there a build ( package ) for ArduSub - blueRov 6 thrusters vehicle

No. But I believe this is rather straightforward to build the code yourself. The link to ArduSub is to be used instead of ArduPilot, though. We don’t build ArduSub as it’s not officially part of ArduPilot project yet.

Ok understand will try to build it from source. When say the link what do u mean - make link line as when building the image ? or ?

I mean adjusting git clone https://github.com/ArduPilot/ardupilot.git to point to the ArduSub repository. I reckon they might use the same build system as the original project.
