I am getting an error while using Cartographer with Turtlebot
I am following this article:
https://google-cartographer-ros-for-t...
I am using ROS-Kinetic. When I use catkin_make_isolated --install --use-ninja
command, I get the following error:
FAILED: cd /home/prateek/catkin_ws/build_isolated/cartographer/install && /usr/bin/protoc --cpp_out /home/prateek/catkin_ws/build_isolated/cartographer/install -I /home/prateek/catkin_ws/src/cartographer /home/prateek/catkin_ws/src/cartographer/cartographer/mapping/proto/trajectory_builder_options.proto
cartographer/mapping/proto/trajectory_builder_options.proto:15:10: Unrecognized syntax identifier "proto3". This parser only recognizes "proto2".

<== Failed to process package 'cartographer':

Please help!
