Rolling build fails due to ros2_control API change (on_init override)

[vincenzoorland0]

Hi,

Building topic_based_ros2_control from the main branch fails on current
ROS 2 Rolling due to a ros2_control API change.

Error:
‘TopicBasedSystem::on_init(const hardware_interface::HardwareInfo&)’
marked ‘override’, but does not override

and:
cannot convert ‘const hardware_interface::HardwareInfo’
to ‘const hardware_interface::HardwareComponentInterfaceParams&’

This appears to be caused by a change in ros2_control where
SystemInterface::on_init now takes
HardwareComponentInterfaceParams instead of HardwareInfo.

The installation docs currently state Rolling is supported, but the
current main branch does not compile against recent Rolling.

Environment:

• ROS 2 Rolling (current apt packages)
• Built from source with colcon
