Research direction

Reproduce the failure with create_agent_ws.sh and build_agent.sh on Ubuntu 22.04 with ROS 2 Humble. Inspect CMakeLists.txt at the find_package call and the referenced fastrtps CMake configuration, using the reported target definitions as the starting point. Done means the micro-ROS agent workspace builds successfully and the agent can be run.

Description

Issue template

  • Hardware description: PC, Ubuntu 22.04
  • RTOS: Ardupilot SITL
  • Installation type: micro_ros_setup
  • Version or commit hash: humble
Steps to reproduce the issue

Follow First micro-ROS Application on Linux. When creating and building the micro-ROS agent

ros2 run micro_ros_setup create_agent_ws.sh
ros2 run micro_ros_setup build_agent.sh

I run into the following error:

stderr: micro_ros_agent
CMake Error at /opt/ros/humble/share/fastrtps/cmake/fastrtps-dynamic-targets.cmake:37 (message):
Some (but not all) targets in this export set were already defined.

Expected behavior

micro-ROS agent installation works as expected and I can use it for working with Ardupilot.

Actual behavior
stderr: micro_ros_agent
CMake Error at /opt/ros/humble/share/fastrtps/cmake/fastrtps-dynamic-targets.cmake:37 (message):
Some (but not all) targets in this export set were already defined.

Additional information

Installing Fast-DDS from source didn't fix the issue for me either
