Hey everyone. I wanted to make sure you were all aware that version 3.2 of the snapcraft CLI was just released today, which includes support for colcon, making it super easy to create ROS2 snaps. A single, confined, installable file containing a ROS2 workspace and all its dependencies can be built with a YAML file that looks like this:
name: ros2-talker-listener version: "0.1" summary: ROS2 Talker/Listener Example description: | This example launches a ROS2 talker and listener. grade: devel confinement: strict base: core18 parts: ros-demos: plugin: colcon source: https://github.com/ros2/demos.git source-branch: crystal colcon-rosdistro: crystal colcon-source-space: demo_nodes_cpp build-packages: [make, gcc, g++] stage-packages: [ros-crystal-ros2launch] apps: run: command: opt/ros/crystal/bin/ros2 launch demo_nodes_cpp talker_listener.launch.py plugs: [network, network-bind]
