Found Issue with Build - fatal error: hardware_interface/handle.hpp

[Wattersto08]

Hey Josh,

Having an issue when building the diffdrive_arduino package (on the humble branch):

--- stderr: diffdrive_arduino In file included from /home/ralph/r7_ws/src/diffdrive_arduino/hardware/diffbot_system.cpp:15: /home/ralph/r7_ws/src/diffdrive_arduino/hardware/include/diffdrive_arduino/diffbot_system.hpp:22:10: fatal error: hardware_interface/handle.hpp: No such file or directory 22 | #include "hardware_interface/handle.hpp" | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ compilation terminated.

It seems there is a missing: filehandle.hpp

I am currently going through the configuration to establish if this is an issue with the build and will keep this thread updated as to how i get on.

Any help here would be superb, Love the series!

Further to the above,

• I have tested the following fork : Migrate to ROS2 Humble #4
• I have also tested with the latest Rolling and Humble ros2 control packages

Things to note - WS is fairly unchanged from the tutorial
