Hi I'm currently trying to use the gazeborosdepthcamera plugin provided by the gazeboplugins package and am getting an error. The SDF I am using also contains other custom written plugins that successfully loads. However I can't seem to get gazebo to load the gazeborosdepthcamera. I've tried exporting the "pluginpath" within the package.xml file as well as set the absolute plugin path in the SDF. The error I am getting is this:

Error [Plugin.hh:127] Failed to load plugin /opt/ros/hydro/lib/libgazeborosdepth_camera.so: libDepthCameraPlugin.so: cannot open shared object file: No such file or directory

I have verified libgazeborosdepthcamera.so exists at the default location (/opt/ros/hydro/lib/). The way I am using the SDF is by first launching a world via roslaunch. I then spawn the SDF using rosrun gazeboros spawn_model. Any ideas why Plugin.hh would fail to load this plugin when the file is verified to be at the specified location? Thanks.

It seems like the plugin can not to find another plugin libDepthCameraPlugin.so which is shipped with gazebo

Is /usr/lib/gazebo-1.9/plugins (or /usr/local/lib/gazebo-1.9/plugins if you installed from source) in your GAZEBO_PLUGIN_PATH variable?

and is this directory containing the missing library?

Hope this helps...

Thanks for the response. I verified the plugin library is in /usr/lib/gazebo-1.9/plugins. I then attempted to get gazebo to find this file by trying the following methods: 1. export GAZEBOPLUGINPATH=/usr/lib/gazebo-1.9/plugins/ 2. Set the "pluginpath" argument in the "gazeboros" tag of package.xml to : plugin_path="/usr/lib/gazebo-1.9/plugins:/opt/ros/hydro/lib"

However both approaches does not help gazebo in locating the libraries. Is there a different way to set GAZEBOPLUGINPATH? Thanks
