Hi,

I originally posted this here: http://answers.ros.org/question/49422/undefined-reference-for-string-constant-in-service/ , then submitted a ticket here: https://code.ros.org/trac/ros-pkg/ticket/5587, so I hope this is in the right place here now ;)

when I define a simple service in Fuerte, e.g.

string my_string
string CONST_STRING=some_value

---

I get an undefined reference to ...::CONST_STRING during linking. Looking at the generated header file, I noticed that CONST_STRING gets declared, but never defined. I tested the same with messages: here it works fine and I can see the definition of CONST_STRING.

The same applies for floatXX-- I guess that problem exists for every constant that can not be encoded into an enum.

Best, Markus
