Ok, i compiled gazebo and it returned the following output. It says built 36 packages with 0 failures but at the same time "Configuring incomplete, errors occurred". Is it ok? http://ros-users.122217.n3.nabble.com/file/n1821719/build_output.log build_output.log Moreover i tried to compile gazebo_worlds and it returned the following output. http://ros-users.122217.n3.nabble.com/file/n1821719/build_output.log build_output.log Any idea?
