Hello,
In part number 5 “Understanding ROS2 Actions” section 5.4 " Create your own action interface" the first thing to do is to create an Action.
From part 5 it was not clear to my how to create an Action but some digging around helped me to solve this issue.
BUT
when performing the command “colcon build” I get an error (see attachment).
I follow the instruction, it is very straight forward with CMakeLists.txt and package.xml (simple copy-paste as far as my understanding goes), but compiling step keeps failing.
Please advise how to continue.
Thank you
