Error while building grid_map_geo for ROS2 Humble

[Claudio-Chies]

Hey,
i cant seem to build grid_map_geo for ROS2 Humble

Steps to reproduce:

git clone https://github.com/ethz-asl/grid_map_geo.git --branch ros2 ~/ros2_ws/src/grid_map_geo
cd ~/ros2_ws/
source /opt/ros/humble/setup.bash
rosdep update
rosdep install --from-paths src --ignore-src -y
colcon build --cmake-args -DCMAKE_BUILD_TYPE=Release -DCATKIN_ENABLE_TESTING=False --packages-up-to grid_map_geo

Which then throws following Error:

CMake Error at CMakeLists.txt:24 (add_library):
  Target "grid_map_geo" links to target "grid_map_core::grid_map_core" but
  the target was not found.  Perhaps a find_package() call is missing for an
  IMPORTED target, or an ALIAS target is missing?


CMake Error at src/CMakeLists.txt:7 (add_executable):
  Target "test_tif_loader" links to target "grid_map_core::grid_map_core" but
  the target was not found.  Perhaps a find_package() call is missing for an
  IMPORTED target, or an ALIAS target is missing?

This depends on an upstream PR. We're working on taking ownership of grid_map. I'll have a fix shortly.

The new grid_map library in use for ROS 2 will be here: https://github.com/ethz-asl/grid_map

The owners of the original library have not been active on the ROS 2 branches, evident by the lack of responses on PR's targetting those branches or even trivial README updates:
ANYbotics/grid_map#404

[Claudio-Chies]

ok, then i'll try with the asl grid_map. thanks

Sounds good! I'll put you as a reviewer for the PR you need.

i was able to build it, see ANYbotics/grid_map#409 for the fixes i had to do on grid_map.
but then the PR's there wont probably go anywhere
