It took a long time to build. For me several days and has not finished yet. After a few days, at step ~318/348, I got internal compiler error: segmentation fault while building ROS Humble on my Radxa Rock 5C(Lite) RK3588S2 2GB. Failed <<< intra_process_demo
Aborted <<< turtlesim
.....
Aborted <<< test_rclcpp
Still waiting for it to finish. Do you know how to solve this? Thanks

The segmentation fault during ROS 2 Humble build on your Rock 5C is most likely caused by insufficient RAM. Building ROS 2 from source is extremely memory-intensive, and 2 GB is generally not enough — the build typically fails with OOM (out-of-memory) errors, which often manifest as segfaults.

Recommendations:

1. Use a board with more RAM — 4 GB minimum, 8 GB recommended for building ROS 2 from source.
2. Add swap space — Creating a swap file (e.g., 4–8 GB) on your eMMC or SD card may help, though it will be very slow on a 2 GB board.
3. Use pre-built ROS 2 packages (if available for your ROS 2 distribution) instead of building from source.
4. Cross-compile — Build ROS 2 on a more powerful host machine and deploy to the Rock 5C.

The build taking several days on a 2 GB board is not unusual — it is expected to be extremely slow due to swap thrashing. The segfault at step 318/348 confirms an OOM condition rather than a board-specific issue.

Thank you for your prompt response! Do you have a link to pre-built ROS 2 packages that would work on Rock 5C 2GB? The instructions https://docs.radxa.com/en/rock5/rock5c/app-development/ros2_humble show how to build ROS2 on Rock5C from source. I thought it is required for it to work on Rock5C. But if there is a pre-built ROS2 packages without the need to build from source, I would love to use. Or if you have detailed instruction on how to build ROS2 on a more powerful host machine and deploy to the Rock 5C, I can try too. Thanks a lot
