准备工作

1、下载代码并安装必要功能包

环境：

Ubuntu16.04 + ros kinetic

记得预先安装以下功能包（可能有遗漏，大家根据报错自行安装吧，或者私聊我）

sudo apt-get install ros-kinetic-ackermann-msgs
sudo apt-get install ros-kinetic-navigation
sudo apt-get install ros-kinetic-openslam-gmapping
sudo apt-get install ros-kinetic-geographic-info
sudo apt-get install ros-kinetic-controller-manager
sudo apt-get install ros-kinetic-gazebo-ros-control
sudo apt-get install ros-kinetic-effort-controllers
sudo apt-get install ros-kinetic-joint-state-controller
sudo apt-get install ros-kinetic-position-controllers
sudo apt-get install ros-kinetic-teb-local-planner

2、编译

将代码放到自己的工作空间里的src编译（应该不会报错）;

Remenber

sudo chmod -R 777 carlike_robot_sim/

终端输入:
cd
cd catkin_ws
catkin_make

[racecar_gazebo] ResourceNotFound: ackermann_cmd_mux

Version

commit/ba22823

How to reproduce

cd catkin_ws/src
catkin_make
roslaunch racecar_gazebo racecar.launch

Actual result
