nav2_mppi_controller colcon build error about navigation2 HOT 3 CLOSED

Builds fine on my machine, many other users, and in CI. What's your OS and build settings? Anything unusual or custom? This is likely something on your side

i tried in two machines running ubuntu 22 and humble , same issue persists.

I bootstrapped a new machine last week, I just installed Humble on it to test this, pulled auto dependencies from rosdep, and built it fine.

The binaries are also turning over in the CI build farm, which is ground truth for everything https://build.ros2.org/job/Hbin_uJ64__nav2_mppi_controller__ubuntu_jammy_amd64__binary/ & in our own internal CI systems.

Not sure what else to tell you - I believe this has to do with your system and since I can't reproduce it locally in docker, bare metal, nor remotely on build farm & CI, nor am I hearing anything from any other users (which there are dozens using MPPI on Humble), the only logical result I can come up with is it has to do with configurations on your side 🙃

With this amount of information, I can't provide much help. You'd be best spent trying to figure out what your system is doing irregularly from standard or what flags you've set that aren't default. 😦 Are you manually setting an old compiler or targeting an older C++ version? Are you on some unusual platform? etc.

Sorry that I can't be more help on this on the open-source side! Perhaps some debugging on your side could result in a fix. Else, if you can give me more information, this is perhaps something Open Navigation can help as part of a consulting service if its still persisting ([email protected]). We unfortunately have limited resources so we can't help every user solve all of their configuration issues as part of our open-source support. To some point, you're on your own when the ground truth can't reproduce or articulate a patch that would resolve your issue for your that isn't disruptive.
