2014-11-06 15:55:31 -0500	asked a question	image_rotate fails to load libimage_rotate.so in ROS Groovy I'm attempting to use image_rotate in ROS Groovy (working with a PR2) but whenever I try to run image_rotate I get the following error. I have tested this on three different machines all running ROS Groovy. Any ideas how to resolve this? $ rosrun image_rotate image_rotate image:=l_forearm_cam/image_color rotated/image:=l_forearm_cam/image_color_rotated __name:=image_rotater [ERROR] [1415309064.421543229]: Failed to load nodelet [/image_rotater] of type [image_rotate/image_rotate]: Failed to load library /opt/ros/groovy/lib//libimage_rotate.so. Make sure that you are calling the PLUGINLIB_EXPORT_CLASS macro in the library code, and that names are consistent between this macro and your XML. Error string: Could not load library (Poco exception = /opt/ros/groovy/lib//libimage_rotate.so: undefined symbol: _ZTVN3tf212BufferClientE)
