Build issue with humble-future branch of events executor (timer reset support)

Inizia riproducendo la build Humble dell’events executor di humble-future e ispeziona rclcpp/src/rclcpp/timer.cpp insieme a rclcpp/include/rclcpp/timer.hpp e detail/cpp_callback_trampoline.hpp. Confronta i commit di rclcpp e rcl per il reset dei timer applicati tramite cherry-pick descritti nel README di events-executor. Il lavoro è completato quando sono stati identificati i commit richiesti o il set di dipendenze richiesto e rclcpp viene compilato correttamente con il supporto per il reset dei timer.

I’m attempting to use iRobot’s events executor with ROS 2 Humble and am trying to build the humble-future branch of the events executor.

As noted in the README, this branch requires additional support from rclcpp and rcl for resetting timers. I cherry-picked the recommended commits, but I’m running into the following build error when compiling rclcpp:

Question

Has anyone successfully built the humble-future branch of events executor with timer reset support? Am I missing a required patch or dependency in rclcpp/rcl?

Any guidance or confirmation on the correct set of commits needed would be greatly appreciated.
