Hello,

Thanks for the info. Do you mind first fixing this on the rolling branch? Feel free to re-use this PR, and just change the target branch. Once it goes into rolling, I can backport to iron and humble.

Also, how do the nav2 dependencies get installed? In rolling, I think we need to compile nav2 from source because it doesn't have binaries available.

ryan@B650-970:~/Dev/grid_map_ws$ rosdep install -y --ignore-src --from-paths src
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
grid_map_costmap_2d: Cannot locate rosdep definition for [nav2_costmap_2d]
grid_map_ros: Cannot locate rosdep definition for [nav2_msgs]

I talked to Steve from NAV2, and for rolling, it will need to be compiled from source, and rosdep should use the -r flag because of circular dependencies in slam_toolbox.

For humble and iron, we should use binaries for nav2 and not compile dependencies from source.

The NAV2 guide on compiling rolling from source is currently incorrect, and I will submit a patch to fix it.
See ros-navigation/docs.nav2.org#515

perception_pcl is available in the ROS index, and should be brought in through rosdep.

Can you try that instead?

Humble CI is passing without compiling any dependencies from source. Because I got no response, and need to more forward with the release, I'm closing this.
