Currently failing due to two problems.

gmake: *** [Makefile:146: all] Error 2

The 2nd errors seems caused by the changes to eigen plugins, because those functions are defined in the plugin.

Hi @Ryanf55

Thanks for following up!

The first issue around BUFFER_HEADER_DEPRECATION looks unrelated.

The second one is likely due to incorrect use of ament_target_dependencies() in grid_map_ros.

The dependencies that are also passed on to downstream dependencies that link against the library (like grid_map_rviz_plugin) should be set as PUBLIC.
