Catkin build errors with mavlink/mavros (kinetic)

[JeffR1992]

I followed the installation instructions for Ubuntu 16.04 with ROS Kinetic (https://github.com/ethz-asl/rotors_simulator), and have run into various errors when using catkin build, which seem to be related to the mavlink/mavros package. The initial build error that I got after attempting my first catkin build was the following:

This was solved by installing the future package. However, on trying to build again, I got the following error:

Which was solved by installing the required package using apt-get install libgeographic-dev. However, when I try and build again, I'm still getting the following error, which I've unfortunately been unable to solve:

This most recent error seems to be in the code, and having done some searching, I'm not sure how I can fix the twist_covariance missing error message. Any help would be greatly appreciated.

P.S. I had assumed that, since I installed a clean version of Ubuntu 16.04, and followed the RotorS installation instructions to a tee (twice, since I thought I did something wrong the first time) such errors would not have occurred. Could this have occurred from some recent dependency changes?

I went through the exact same steps as you did. Ended up just renaming msg.twist_covariance to msg.velocity_covariance on line 234. As far as I can tell it builds and runs fine. Curious what the right way to fix this would be though. I'm on 18.04 with ROS Melodic.

Update ros-*-mavlink

I used the latest ‘marvos’ and have successfully solved the same problem.

The latest marvos will solve the problem I guess. I'm using Melodic 18.04 and my rosinstall file is like this:

Update ros-*-mavlink

Could you elaborate how to "Update ros-*-mavlink"?

renaming msg.twist_covariance to msg.velocity_covariance on line 234 Can you tell me where msg.twist_covariance is stored?
