How do I specify which packages are needed to run code in a package or build packages?

e.g.

  <build_depend> industrial_robot_client </build_depend>
  <build_depend> simple_message </build_depend>

  <run_depend> industrial_robot_client</run_depend>

why is "simple_message" used to build this package and there not simple_message in the <run_depend> tag?

Can you please add which package this is? It is possible for things to be build_depend only, but that is only in certain cases.

One other possibility is that the author relied on industrial_robot_client transitively providing the simple_message run dependency.

this is abb_driver package. industrial_robot_client and simple_message are part of ROS-Industrial

Hm. Could be that I forgot to add simple_message as a run_depends. But as I wrote: industrial_robot_client will transitively pull in the simple_message dependency. Whether that is a nice thing to do is something else.

what is the difference between "run" and "build" in ROS.

Briefly: run dependencies are needed to be able to run a specific program, while build dependencies are needed to be able to build it (compiling is one step in building a program).
