fatal error: rtabmap/core/LocalGrid.h: no such file or directory，But I'm on rtabmap_ The header file path was added to the Cmakelist.txt folder in the util folder, but it still reported an error. Why

Make sure to use latest master from rtabmap too.

I met the same question.

For rtabmap_ros and rtabmap, I use the default master branch. But when I turned rtabmap_ros to noetic-devel branch (i use noetic), the error was resolved.

I am not sure if there are potential risks but it did work

[matlabbe]

Did rtabmap has been re-installed? rtabmap/core/LocalGrid.h has been added in latest version. The master branch of rtabmap and rtabmap_ros should be noetic compatible (as shown in this build).

I am also getting this error. Similar to @WenyuLWY I managed to build using humble-devel branch, which isn't up-to-date - hence successful build. I tried re-installing many times, and so for me atleast the rtabmap was latest version. The latest build of rtabmap_ros (more specifically the latest commit: 2f365ab7 on 18.12.23 at 08:46) seems to be the problem.

I checked, the LocalGrid.h file exists and is built along with the other .h files included from rtabmap/core in MapsManager.h (in rtabmap_util/include) so this error is very illogical as this is not the first include from rtabmap/core (and therefore shouldn't be a dependency issue)

@matlabbe i have little experience and little idea what else could cause this error if 1) the file exists 2) other similar #include-s work. So i can provide more information only based on questions.

ros2 doctor gives warnings that 3 packages have been updated (and i haven't): robot_localization, rqt_joint_trajectory_controller, behaviortree_cpp_v3

rtabmap_util (though rtabmap_conversions) may have found another rtabmap installed somewhere not having the header file. The humble-devel branch has been updated yesterday to use latest code. I also updated the minimum rtabmap version to 0.21.3 so that cmake/colcon should reject any other rtabmap found with lower version.

[LightProhvet]

Yes, that seemed to fix it. rtabmap_util built succesfully. I think this is now solved?
