Humble main is expected to fail here until the next sync. Merging.

It is not possible to build the package on humble because of #include <realtime_tools/realtime_box_best_effort.hpp>

The file does not exist while the file <realtime_tools/realtime_box_best_effort.h> does exist and then it builds fine

You experience this because ros-controls/realtime_tools@393a384 is released, but not yet synchronized to main. This is also, why our binary-testing build succeeds, while the binary main build fails. Building this package from the head branch might require building upstream packages from source from time to time. Please see the source build instructions for details.

If you don't want to go through this trouble, you might just use our binary installation packages instead?
