源码安装ros2步骤，参考官方教程（英文）：官网教程
- 设置Locale
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
- 添加ROS 2 apt 仓库
sudo apt update && sudo apt install curl gnupg2 lsb-release
curl http://repo.ros2.org/repos.key | sudo apt-key add -
sudo sh -c 'echo "deb [arch=amd64,arm64] http://packages.ros.org/ros2/ubuntu `lsb_release -cs` main" > /etc/apt/sources.list.d/ros2-latest.list'
- 安装开发工具和ROS工具
sudo apt update && sudo apt install -y \
build-essential \
cmake \
git \
python3-colcon-common-extensions \
python3-lark-parser \
python3-pip \
python-rosdep \
python3-vcstool \
wget
python3 -m pip install -U \
argcomplete \
flake8 \

sudo apt install --no-install-recommends -y \

libtinyxml2-dev
# For Crystal Clemmys
sudo apt install libopensplice69 # from packages.ros.org/ros2/ubuntu
# For Bouncy Bolson
sudo apt install libopensplice67 # from packages.ros.org/ros2/ubuntu
sudo apt install -q -y \
rti-connext-dds-5.3.1 # from packages.ros.org/ros2/ubuntu
cd /opt/rti.com/rti_connext_dds-5.3.1/resource/scripts && source ./rtisetenv_x64Linux3gcc5.4.0.bash; cd -
- 获取ROS2源码：
mkdir -p ~/ros2_ws/src
cd ~/ros2_ws
wget https://raw.githubusercontent.com/ros2/ros2/release-latest/ros2.repos
vcs import src < ros2.repos
最后一步耗时不确定，看网速，成功的画面和结果参考：vcs import src ros2.repos
- build 源码，注意系统不一样，指令不一样：
cd ~/ros2_ws/
# On Ubuntu Linux Bionic Beaver 18.04 用下面这个指令
colcon build --symlink-install
# On Ubuntu Linux Xenial Xerus 16.04 用下面这个指令
colcon build --symlink-install --packages-ignore qt_gui_cpp rqt_gui_cpp
- 编译时候第一次出现这个问题：
make[2]: *** [assimp-4.1.0-prefix/src/assimp-4.1.0-stamp/assimp-4.1.0-download] Error 1
make[1]: *** [CMakeFiles/assimp-4.1.0.dir/all] Error 2
make: *** [all] Error 2
---
Failed <<< rviz_assimp_vendor [ Exited with code 2 ]
Aborted <<< rcl_interfaces
Aborted <<< lifecycle_msgs
Aborted <<< rviz_ogre_vendor
解决办法是重新编译一次就不会了：
colcon build --symlink-install --packages-ignore qt_gui_cpp rqt_gui_cpp
- 第二次遇到这个问题：
--- stderr: rviz_ogre_vendor
CMake Error at CMake/Utils/MacroLogFeature.cmake:100 (MESSAGE):

Failed <<< rviz_ogre_vendor [ Exited with code 2 ]
Aborted <<< geometry_msgs
Aborted <<< test_msgs
Aborted <<< std_srvs
解决办法，我尝试了补充下面的库：
/*
The following NEW packages will be installed:
cppcheck libpocofoundation9v5-dbg python3-nose
The following NEW packages will be installed:
clang-format pydocstyle pyflakes pyflakes3 python-pyflakes python3-funcsigs python3-mock python3-pbr python3-pep8 python3-pyflakes uncrustify
*/
sudo apt install cppcheck libpocofoundation9v5-dbg python3-nose clang-format pydocstyle pyflakes pyflakes3 python-pyflakes python3-funcsigs python3-mock python3-pbr python3-pep8 python3-pyflakes uncrustify
最后起作用的是这句话：
sudo apt install libxaw7-dev
我的理解是编译的时候是找dev版本里面的，而不是正式版本里面的，所以就算我之前安装了libxaw7也不行。成功如下：
- 第三次遇到这个问题：
--- stderr: ros1_bridge
Failed to load Python extension for LZ4 support. LZ4 compression will not be available.
---
原因是对应的库没有安装好，解决办法：
查找lz4相关的安装包
apt-cache search lz4
根据提示可以知道是python相关的包不对，那么我们就重新安装对应的包
sudo apt install python-roslz4
- 继续编译：
colcon build --symlink-install --packages-ignore qt_gui_cpp rqt_gui_cpp
- 最终全部成功啦！不容易啊！
colcon build --symlink-install --packages-ignore qt_gui_cpp rqt_gui_cpp

Summary: 230 packages finished [54.5s]
- 测试例程，打开两个终端ctrl+t，分别输入：
. ~/ros2_ws/install/local_setup.bash
ros2 run demo_nodes_cpp talker
. ~/ros2_ws/install/local_setup.bash
ros2 run demo_nodes_py listener
- 当colcon成功完成构建后，输出将位于安装目录中。要使用需要的可执行文件和库，例如将install / bin目录添加到路径中。 colcon将在安装目录中生成bash / bat文件以帮助设置环境。这些文件将向路径和库路径添加所需的元素，并提供由包导出的任何导出的bash或shell命令。所以我们要执行指令完成设置环境：
. install/setup.bash
成功的情况下不会有任何输出。
- 到此完成安装，再测试一个例子：
打开两个终端ctrl+t，分别输入
. ~/ros2_ws/install/local_setup.bash
ros2 run examples_rclcpp_minimal_subscriber subscriber_member_function
. ~/ros2_ws/install/local_setup.bash
ros2 run examples_rclcpp_minimal_publisher publisher_member_function
- 如果不加前面的指令，新打开一个终端，直接执行rosrun会出现：
ros2: command not found
解决办法是：
. ~/ros2_ws/install/local_setup.bash
-
愉快地使用ros2吧！
-
如果想用回ros1，需要对~/.bashrc进行设置，不然你输入roscore的时候会提示：
Traceback (most recent call last):

SyntaxError: invalid syntax
解决办法：
查看系统变量
printenv | grep ROS
修改bashrc文件
gedit ~/.bashrc
添加内容（以主机是本机为例）：
ROS_ROOT=/opt/ros/kinetic/share/ros
ROS_PACKAGE_PATH=/home/peng/catkin_ws/src:/opt/ros/kinetic/share:/opt/ros/kinetic/stacks
ROS_MASTER_URI=http://localhost:11311
ROSLISP_PACKAGE_DIRECTORIES=/home/peng/catkin_ws/devel/share/common-lisp
ROS_DISTRO=kinetic
ROS_ETC_DIR=/opt/ros/kinetic/etc/ros
再次运行则可以了。
- 补充问题：
--- stderr: opensplice_cmake_module
CMake Warning at cmake/Modules/FindOpenSplice.cmake:100 (find_package):
Could not find a package configuration file provided by "opensplice" with
any of the following names:
openspliceConfig.cmake
opensplice-config.cmake
Add the installation prefix of "opensplice" to CMAKE_PREFIX_PATH or set
"opensplice_DIR" to a directory containing one of the above files. If
"opensplice" provides a separate development package or SDK, be sure it has
been installed.
Call Stack (most recent call first):
CMakeLists.txt:8 (find_package)
原因是opensplice库没安装好，解决办法：
sudo apt install opensplice67
- 搞定。
