Excuse me,I got a error when I used the repositories code constructed a workspace to build .Can you tell why?

The error information is:

Hey, make sure crab_msgs is compiled before crab_body_kinematics. The latter can't find these messages compiled when it's required.

Thanks~

Thanks~,Can you tell me how to make sure crab_msgs is compiled before crab_body_kinematics ?

Sure,

  1. Add crab_msgs as build_depend and run_depend here.

  2. Move this line after 15 so the package is in the list of catkin REQUIRED COMPONENTS.

  3. Finally, according to this documentation, add ${catkin_EXPORTED_TARGETS} before this line:

add_dependencies(body_kinematics ${catkin_EXPORTED_TARGETS})

If this works for you, will you open a PR, please?

Thanks~,I have receive you reply.I will try again later.But I don't know the "PR".Can you explain the "PR"?
