简直就是ros源码阅读顺序表

1. 首先安装基本依赖包：

安装ros依赖：

sudo apt install python3-rosdep2 python3-rosinstall-generator python3-rosinstall build-essential python3-defusedxml python3-netifaces

安装编译依赖：

sudo apt install libeigen3-dev libboost-thread-dev libgtest-dev libconsole-bridge-dev libpoco-dev python3-sip-dev libboost-filesystem-dev libboost-program-options-dev libtinyxml2-dev libtinyxml-dev pyqt5-dev libcurl4-openssl-dev libboost-regex-dev liblz4-dev libbz2-dev libboost-singals-dev liburdfdom-headers-dev liburdfdom-dev uuid-dev libassimp-dev libogre-1.9-dev libyaml-cpp-dev

2. 配置rosdep

mkdir setups
cd setups
touch rosdep
chmod +x ./rosdep

添加脚本内容：

#!/usr/bin/env python3

from rosdep2.main import rosdep_main
rosdep_main()

执行

sudo ./rosdep init
./rosdep update

3. 获取基本ros环境的源码

首先下载执行文件

wget https://raw.githubusercontent.com/ros-infrastructure/rosinstall_generator/master/bin/rosinstall_generator
wget https://raw.githubusercontent.com/vcstools/wstool/master/scripts/wstool
wget https://raw.githubusercontent.com/ros-infrastructure/rospkg/master/scripts/rosversion
wget https://raw.githubusercontent.com/ros-infrastructure/catkin_pkg/master/bin/catkin_find_pkg
wget https://raw.githubusercontent.com/ros-infrastructure/catkin_pkg/master/bin/catkin_create_pkg
wget https://raw.githubusercontent.com/ros-infrastructure/catkin_pkg/master/bin/catkin_generate_changelog
wget https://raw.githubusercontent.com/ros-infrastructure/catkin_pkg/master/bin/catkin_tag_changelog
wget https://raw.githubusercontent.com/ros-infrastructure/catkin_pkg/master/bin/catkin_test_changelog
chmod +x ./rosinstall_generator
chmod +x ./wstool
chmod +x ./rosversion
chmod +x ./catkin_find_pkg
chmod +x ./catkin_create_pkg
chmod +x ./catkin_generate_changelog
chmod +x ./catkin_tag_changelog
chmod +x ./catkin_test_changelog

记得修改第一行引用的python 为python3，并把下面的from _future_ import 行删除

新建总工程目录并执行ros源代码下载

mkdir ../workspace
cd ../workspace
../setups/rosinstall_generator desktop_full --rosdistro melodic --deps --tar > melodic-desktop-full.rosinstall
../setups/wstool init -j8 src melodic-desktop-full.rosinstall

如果安装失败的话，可以试试继续安装：

../setups/wstool update -j 8 -t src

接下来解决依赖

../setups/rosdep install --from-paths src --ignore-src --rosdistro melodic -y

4. 安装Catkin

从Github Catkin上下载源码，cmake并选择python版本为3，安装地址选为自己的环境文件夹env

export ROS_PYTHON_VERSION=3
mkdir build
cd build
cmake ..
make DESTDIR=xxxxxxx
make install

然后回到workspace目录 
修改 ./src/orocos_kinematics_dynamics/python_orocos_kdl/CMakeLists.txt 中

SET(PYTHON_VERSION 2 CACHE STRING "Python Version")  

改为

SET(PYTHON_VERSION 3 CACHE STRING "Python Version") 

修改 src/dynamic_reconfigure/cfg/Test.cfg 和 src/nodelet_core/nodelet_topic_tools/cfg/NodeletThrottle.cfg 第一行为

#! /usr/bin/env python3

添加 regex 依赖到 src/ros_comm/rosconsole/CMakeLists.txt 72 行后（维持其他不变，添加boost_regex）

target_link_libraries(rosconsole ${rosconsole_backend_LIBRARIES} ${catkin_LIBRARIES} ${Boost_LIBRARIES} boost_regex)

修改 src/vision_opencv/cv_bridge/CMakeLists.txt 11 行为

find_package(Boost REQUIRED python-py36)

../env/setup.sh 最后一行添加

export ROS_PYTHON_VERSION=3

5. 开始编译

source ../env/setup.zsh
catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release
mv ../setups/* ../env/bin/

如果想更换安装地点的话，可以在最后catkin之后加 –install-space xxxxxxx

6. 开始使用ROS

以后任何新Term执行ROS命令前都要载入配置环境（也可以加入~/.bashrc或者~/.zshrc里面自动执行）

source ../env/setup.zsh

启动 ros 调度核心

roscore

开新窗口启动 rviz 来测试

rosrun rviz rviz

若能成功启动，万事大吉！

备注：rqt 系列的 ros 程序似乎没有自动修改第一行为 python3， 需要手动修改。

1’. 懒人福利

简单编译后打包好的 deb 文件（不对安装结果负责，因为依赖太多了数不清，所以如果有不能运行的按照log添加添加吧，另外欢迎随意修正这个 deb），如果你和我一样用的 debian testing 系统，欢迎直接 copy 我编译完的二进制包：https://pan.baidu.com/s/1WmZAA7J-2uvSz8S9-XmdWQ
