[grid_map_pcl] pointcloud_publisher_node not found, yaml parameters not loaded

[sarahnator]

Hi,

I downloaded the grid_map_pcl package through apt-get and followed the instructions in the grid_map_pcl readme to convert a pointcloud into a grid map, but ran into two issues:

• When I run roslaunch grid_map_pcl grid_map_pcl_loader_node.launch I get back an error that the executable pointcloud_publisher_node was not found or needs to be set to executable with +x (I'm not sure if this is the issue, but pointcloud_publisher_node.cpp does not appear to be listed as a source file in CMakeLists.txt).
• Changes to parameters.yaml are reflected in the rosparam get <parameter> command, but the default values in PclLoaderParameters.hpp are still used.
