编译后遇到报错 ，解决问题的网址：https://blog.csdn.net/xihuanzhi1854/article/details/82154502

详细步骤：

1. sudo sh -c 'echo "deb http://packages.osrfoundation.org/gazebo/ubuntu-stable `lsb_release -cs` main" > /etc/apt/sources.list.d/gazebo-stable.list'
2. wget http://packages.osrfoundation.org/gazebo.key -O - | sudo apt-key add -
3. sudo apt-get update
4. sudo apt-get install gazebo7 gazebo7-common
   升级结束，再安装一个包（报错：fatal error: ignition/math/Inertial.hh: No such file or directory）
5. sudo apt-get install libignition-math2-dev

完成 ，gazebo成功从7.0 升级到7.14 可以跑小车了，gzclient端加载gzserver的图像也可以显示了。

wget http://packages.osrfoundation.org/gazebo.key -O - |  apt-key add -

sh -c 'echo "deb http://packages.osrfoundation.org/gazebo/ubuntu-stable `lsb_release -cs` main" > /etc/apt/sources.list.d/gazebo-stable.list'
