Ubuntu 20.04下源码编译安装ROS 2 Foxy Fitzroy

由 半腔热情 提交于 2020-08-08 04:27:59
ROS 2 Foxy Fitzroy（以下简称Foxy）于2020年6月5日正式发布了，是LTS版本，支持到2023年5月。本文主要根据官方的编译安装教程[1]完成，并记录编译过程中遇到的问题。

1. 系统要求

在官方给出的Foxy目标系统中，Ubuntu Linux - Focal Fossa (20.04) 64位是首选，本文也选择Ubuntu 20.04 64位，其他还包括Debian Linux - Buster (10)、Fedora 32、Arch Linux、OpenEmbedded / webOS OSE，但Foxy还没有充分测试，不推荐使用。

 

2. 系统设置

(1) 设置locale

确保系统locale支持UTF-8，在终端运行locale查看。
如果不支持UTF-8，运行以下代码
sudo locale-gen en_US en_US.UTF-8 sudo update-locale LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8 export LANG=en_US.UTF-8

(2) 添加ROS 2 apt仓库

1) 用apt命令认证GPG key
sudo apt update && sudo apt install curl gnupg2 lsb-release curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -
此时可能会遇到ros.asc无法下载的问题。
问题1：ERROR: unable to process source https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc 之类的错误，可能是因为raw.githubusercontent.com网站被墙了。
解决方法：修改hosts文件，添加这个网站的ip地址[2]。
#打开hosts文件
sudo gedit /etc/hosts
#在文件末尾添加
151.101.84.133 raw.githubusercontent.com
2) 添加仓库到源列表中
推荐使用国内清华ROS 2镜像：
sudo sh -c 'echo "deb [arch=amd64] https://mirrors.tuna.tsinghua.edu.cn/ros2/ubuntu/ `lsb_release -cs` main" > /etc/apt/sources.list.d/ros2-latest.list'
也可以使用官方ROS 2仓库，速度可能会慢。
sudo sh -c 'echo "deb http://packages.ros.org/ros2/ubuntu `lsb_release -cs` main" > /etc/apt/sources.list.d/ros2-latest.list'

(3) 安装开发工具和ROS工具

sudo apt update && sudo apt install -y \
  build-essential \
  cmake \
  git \
  libbullet-dev \
  python3-colcon-common-extensions \
  python3-flake8 \
  python3-pip \
  python3-pytest-cov \
  python3-rosdep \
  python3-setuptools \
  python3-vcstool \
  wget
# install some pip packages needed for testing
python3 -m pip install -U \
  argcomplete \
  flake8-blind-except \
  flake8-builtins \
  flake8-class-newline \
  flake8-comprehensions \
  flake8-deprecated \
  flake8-docstrings \
  flake8-import-order \
  flake8-quotes \
  pytest-repeat \
  pytest-rerunfailures \
  pytest
# install Fast-RTPS dependencies
sudo apt install --no-install-recommends -y \
  libasio-dev \
  libtinyxml2-dev
# install Cyclone DDS dependencies
sudo apt install --no-install-recommends -y \
  libcunit1-dev

3. 获取ROS 2代码

创建工作空间，并获取ROS 2代码。 
mkdir -p ~/ros2_foxy/src
cd ~/ros2_foxy
wget https://raw.githubusercontent.com/ros2/ros2/foxy/ros2.repos
vcs import src < ros2.repos

如果Fast-DDS无法正常下载，自行下载解压到~/ros2_foxy/src/eProsima/Fast-DDS。

https://github.com/eProsima/Fast-DDS​github.com

4. 使用rosdep安装依赖

sudo rosdep init
rosdep update
rosdep install --from-paths src --ignore-src --rosdistro foxy -y --skip-keys "console_bridge fastcdr fastrtps rti-connext-dds-5.3.1 urdfdom_headers"

5. 编译ROS 2

cd ~/ros2_foxy/
colcon build --symlink-install
编译过程中遇到的问题如下：
问题2： ImportError: "from catkin_pkg.package import parse_package" failed: No module named catkin_pkg.package
解决方法[3]：pip install catkin_pkg
问题3： importError: No module named em
解决方法[4]：python -m pip install empy
问题4： importError: No module named lark
解决方法[5]：python -m pip install lark-parser
问题5： can not locate Clang's built-in include directory
解决方法[6]：重装shiboken2 sudo apt remove shiboken2 libshiboken2-dev libshiboken2-py3-5.14 pip3 install --user shiboken2
问题6： 几处因为ExternalProject_Add下载卡住的地方，修改对应的CMakeLists.txt。

      ${extra_cmake_args})

 6. 环境设置

打开~/.bashrc文件，在文件最后添加，这样每次打开终端会自动执行source命令。 
source ~/ros2_foxy/install/setup.bash

7. 测试

打开一个终端，运行C++编写的talker： 
ros2 run demo_nodes_cpp talker

打开另外一个终端，运行Python编写的listener：

ros2 run demo_nodes_py listener

运行结果：

说明C++和Python的API可以正常工作。
