Msg Dependencies in Catkin

edit

It says there to add the following:

add_dependencies(your_program ${catkin_EXPORTED_TARGETS}) add_dependencies(your_library ${catkin_EXPORTED_TARGETS})

What exactly is "your_program" and "your_library", do they mean 'Package name' and 'Executable'?

They stand for whichever of your build targets depend on the message headers. A C++ build target is usually either an executable or a library.

Now I'm getting the error "Adding dependency to non-existent target: beginner_tutorials"

Am I supposed to be adding something else? I already included "target_link_libraries" the same way it is done for talker and listener in the tutorials.

Apparently you have some dependency on beginner_tutorials, which is not being resolved. Can you roscd beginner_tutorials?

if I do source ./devel/setup.bash, yes.

BUT, if I do "rosmsg package beginner_tutorials" nothing shows up - not even std_msgs/String

You HAVE TO source ./devel/setup.bash ;) After you do that, you should be able to catkinise your package.
