The project appears to have an upstream ticket about the issue.

The warning you cite is a warning not the error that's stopping compile.

At least one of the errors in this is already ticketed on the repository.


I would suggest that you follow up over there.

To get better help here. Please ask a question with a self contained minimal example which can be reproduced by whoever is trying to help you.

  • $\begingroup$ As there's one or more bugs in the upstream code that's the place to follow up on it. If you want help with understanding the general compiler warnings and errors that's [off topic for this forum](robotics.stackexchange.com/help/on-topic ) but the main stack overflow can help you with understanding the programming error. If you want significant help with that you will have the best luck isolating it down to a short self contained correct example. $\endgroup$
