ubuntu 20.04 安装源码编译 ros humble过程

公司要兼容ros1还需要ros2 这个时候不得不使用ubuntu20.04 安装 humble 但实际上在20.04上安装humble是需要在源码编译的。
根据这个帖子 https://blog.csdn.net/m0_62353836/article/details/129730981 重写一份，以应对无法下载的问题
系统配置

#检查是否为UTF-8编码，是则跳过！
locale  


#非UTF-8 执行下列命令
sudo apt update && sudo apt install locales
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

#验证是否设置成功
locale  

增加带有apt 的ros2 gpg秘钥

sudo apt update && sudo apt install curl
sudo curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -o /usr/share/keyrings/ros-archive-keyring.gpg

这里由于无法通过githubusercontent下载，所以这么改

sudo curl -sSL https://raw.gitmirror.com/ros/rosdistro/master/ros.key -o /usr/share/keyrings/ros-archive-keyring.gpg

将存储库添加到源码

echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/ros-archive-keyring.gpg] http://packages.ros.org/ros2/ubuntu $(. /etc/os-release && echo $UBUNTU_CODENAME) main" | sudo tee /etc/apt/sources.list.d/ros2.list > /dev/null

安装开发工具和ROS工具
安装通用软件包

sudo apt update && sudo apt install -y \
  python3-flake8-docstrings \
  python3-pip \
  python3-pytest-cov \
  ros-dev-tools

安装Ubuntu20.04所需软件包

python3 -m pip install -U \
   flake8-blind-except \
   flake8-builtins \
   flake8-class-newline \
   flake8-comprehensions \
   flake8-deprecated \
   flake8-import-order \
   flake8-quotes \
   "pytest>=5.3" \
   pytest-repeat \
   pytest-rerunfailures

获取ros2源码

mkdir -p ~/ros2_humble/src
cd ~/ros2_humble
vcs import --input https://raw.githubusercontent.com/ros2/ros2/humble/ros2.repos src

这里还是无法下载需要手动下载https://raw.githubusercontent.com/ros2/ros2/humble/ros2.repos这个文件,我们可以通过在镜像网站上下载此文件然后把github.com 改成bgithub.xyz。即可首先我们下载这个文件

wget https://raw.gitmirror.com/ros2/ros2/humble/ros2.repos
