How are service.h files are generated from service.srv files ?

edit

I took this example from github and i guess it already has all the dependencies. @gvdhoorn

@gvdhoorn : yes, you were correct : fixed it by adding dependencies.

well, I just checked it, and it doesn't (as you probably also found out).

yes : dependencies added !

@gvdhoorn again coming back to my previous question, how are headers generated from IDL ? For example, if i need to create a new service file, then how can I add the header file in the cpp. Normally it says no such file found.

Normally it says no such file found.

it should only give that error if you've not followed procedure.

provided the msg / srv file exists, you've added the dependencies to your target and followed the docs on generating msgs / srvs things should work.

It's all documented in the Catkin documentation I linked earlier and on the ROS wiki.

I created an overlay space and copied the demo_nodes_cpp example in ROS2 into the overlay ws and renamed it(heatflow_cpp). Created a new service file(heatFlow.srv) and changed the name of the service file in the CMAKELISTS and then included heatFlow.hpp in the cpp.Am i forgetting something ?
