When I run "gazebo pioneer2dx.world" gazebo starts up fine, but when I run "player gazebo.cfg" I get the following error messages:
error : Failed to load plugin libgazebo_player.
error : libtool reports error: file not found
error : plugin search path: /home/ulrik/Work/thirdparty/gazebo_source/test:.:/usr/local/lib/
error : failed to load plugin: libgazebo_player
error : failed to parse config file gazebo.cfg driver blocks
Both player (version 3.1.0) and gazebo (version 1.9) are installed in /usr/local and libgazebo_player.so is located in /usr/local/lib. LD_LIBRARY_PATH is set to /usr/local/lib. I installed player before gazebo and gazebo found player when installed. (No warnings or errors when running cmake.)
