Hi everyone,

I am using gazebo-2.2.6. I wanted to learn more about plugins on gazebo. I tried testing the elevator example (http://gazebosim.org/tutorials?tut=elevators&cat=plugins). However, even if gazebo is launched when entering "gazebo worlds/elevator.world", the example does not work correctly, no event is triggered. I get the errors : Failed to load plugin libSimEventsPlugin.so: libSimEventsPlugin.so: cannot open shared object file: No such file or directory Error [Plugin.hh:149] Failed to load plugin libgazeboroselevator.so: libgazeboroselevator.so: cannot open shared object file: No such file or directory

I didn't find the ".so" files in my computer. Should I install some packages ? If so, which ones ?

Any suggestions ? Thank you in advance !
