I am following the tutorial for compiling a custom Gazebo plugin: http://classic.gazebosim.org/tutorials?tut=contact_sensor&cat=sensors
I am getting the following two errors in the ContactPlugin.hh file:
identifier "sdf" is undefined
namespace "gazebo::event" has no member "ConnectionPtr"
I tried to install everything I could find regarding Gazebo and SDF. I am at a loss. In my include path are:
/usr/include/gazebo-11/**
/usr/include/sdformat-9.8/sdf/**
Any help would be greatly appreciated, Thanks!
