Using custom interface for another package but getting build error: No such file or directory

[TimSch]

I created an custom action interface on my own machine following the course ROS2 Basics in 5 Days (C++). It build without errors, and when i use the command ros2 interface show custom_interfaces/action/Stitching, it is showing the correct information about the interface.

I wanted to use this interface now for building an action server. But there i get the following error:

Starting >>> stitching_action_server
--- stderr: stitching_action_server                             
~/ros2_ws/src/stitching_action_server/src/stitching_action_server.cpp:8:10: fatal error: custom_interfaces/action/stitching.hbb: No such file or directory

I would appreciate any help!

Hi @TimSch ,

I did not take a deep look into your error, but I just looked at the #include line. You have written .hbb instead of .hpp. Probably that is what is causing you the problem.

Replace #include "custom_interfaces/action/stitching.hbb"
with #include "custom_interfaces/action/stitching.hpp"

Hopefully that should fix your issue. Let me know if your issue is fixed!
