Cartographer安装

# Install wstool and rosdep.
sudo apt-get update
sudo apt-get install -y python-wstool python-rosdep ninja-build

# Create a new workspace in ‘catkin_ws‘.
mkdir catkin_ws
cd catkin_ws
wstool init src

# Merge the cartographer_ros.rosinstall file and fetch code for dependencies.
wstool merge -t src https://raw.githubusercontent.com/googlecartographer/cartographer_ros/master/cartographer_ros.rosinstall
wstool update -t src
//在这一步可能会显示无法下载cere-solver
/*
解决办法
1.手动下载cere-solver 然后放到src中
# Install proto3.
src/cartographer/scripts/install_proto3.sh

# Install deb dependencies.
# The command ‘sudo rosdep init‘ will print an error if you have already
# executed it since installing ROS. This error can be ignored.
sudo rosdep init
rosdep update
rosdep install --from-paths src --ignore-src --rosdistro=${ROS_DISTRO} -y
//这里要修改ROS_DISTRO为自己的ros版本如kinetic或者indigo
# Build and install.
catkin_make_isolated --install --use-ninja
source install_isolated/setup.bash
