I want to ardupilot SITL simulator.
I’m following this video - https://www.youtube.com/watch?v=1FpJvUVPxL0
During the build process, I get an error like a picture when I first run Sim_vehicle.py -w, and I want to know the solution.
look like you are using the wrong mavlink version.
did you do
git submodule update --init --recursive
Yes I did it. should I try again?
Yes, please do. Repeat until it works
