Error building Agent using ROS2 colcon

[Geol-23]

Hello, I'm working with the PX4 environment and I would like to communicate with the flight controller using the uXRCE-DDS framework. I have followed the PX4 guide. When building the package in the ROS2 workspace I get a version error. I am new to the ROS2 environment so any help is appreciated.

• Hardware description: I am running the agent on a Raspberry Pi 4 and I intend to use a serial link to communicate
• OS: Ubuntu 22.04
• Installation type: (not sure)
• Version or commit hash: Humble

Steps to reproduce the issue

1. Using a fresh installation of Humble, create the workspace and clone the agent under the src
2. run colcon build

Expected behavior

Successfully build

Actual behavior

The following error is outputted:

CMake Error at CMakeLists.txt:153 (find_package): Could not find a configuration file for package "fastcdr" that is compatible with requested version "2".

The following configuration files were considered but not accepted:

/opt/ros/humble/lib/cmake/fastcdr/fastcdr-config.cmake, version: 1.0.24

gmake: *** [Makefile:166: cmake_check_build_system] Error 1 --- Failed <<< microxrcedds_agent [0.34s, exited with code 2]

Solved it. All I had to do was install an earlier version of the agent.
