colcon build freeze a Raspberry Pi

edit

Thanks all for reading and helping.

I'm attempting to install and use Humble on a fresh 22.04 install on a Raspberry Pi reTerminal (CM4) with 4G RAM. Ubuntu 22.04.1 LTS (GNU/Linux 5.15.0-1015-raspi aarch64). I've followed the instructions here (https://docs.ros.org/en/humble/index.html) using the apt install binaries.

jon@adventure:~$ env | grep ROS
ROS_VERSION=2
ROS_PYTHON_VERSION=3
ROS_LOCALHOST_ONLY=0
ROS_DISTRO=humble

jon@adventure:~$ gcc --version
gcc (Ubuntu 11.2.0-19ubuntu1) 11.2.0

Everything appears to be installed without error, however when I go to build the demo in the 'Build Workspace' tutorial the system freezes running the command colcon build --symlink-install. I let it run for about 30 minutes before cancelling the process. It appeared to run smoothly other than the surprise warnings up to about 50% where it sat for majority of the time. I executed the commands from an SSH shell, and noted my direct linked monitor was frozen during the pause as well.

This is the output from running the commands from here:

If a package in a merged underlay workspace is overridden and it installs headers, then all packages in the overlay must sort their include directories by workspace order. Failure to do so may result in build failures or undefined behavior at run time.
If the overridden package is used by another package in any underlay, then the overriding package in the overlay must be API and ABI compatible or undefined behavior at run time may occur.

If you understand the risks and want to override a package anyways, add the following to the command line:
    --allow-overriding examples_rclcpp_minimal_action_client examples_rclcpp_minimal_action_server examples_rclcpp_minimal_client examples_rclcpp_minimal_composition examples_rclcpp_minimal_publisher examples_rclcpp_minimal_service examples_rclcpp_minimal_subscriber examples_rclcpp_minimal_timer examples_rclcpp_multithreaded_executor examples_rclpy_executors examples_rclpy_minimal_action_client examples_rclpy_minimal_action_server examples_rclpy_minimal_client examples_rclpy_minimal_publisher examples_rclpy_minimal_service examples_rclpy_minimal_subscriber

This may be promoted to an error in a future release of colcon-override-check.
