[ros-users] actionlib over multiple packages

I am trying to learn how to use actionlib. I would like my client and
server to use the actionlib generated messages from another package. I
believe this should be possible, but I get a compilation error when
compiling the client or server.



Specifics:

I took the turtle_actionlib tutorial and split it into 3 packages:
trtl_msgs, trtl_client, and trtl_server. trtl_msgs contains no code and
only has the .action files. I modified the CMake file accordingly and
this rosmakes fine. (The .msg files get generated properly including
the .h files and .py files.) When I try to rosmake the client, I get
this error:



/home/baxelrod/ros-tutorials/ros_pkg_tutorials/trtl_client/src/shape_cli
ent.cpp:4:35: error: trtl_msgs/ShapeAction.h: No such file or directory



I have double checked that trtl_msgs is listed as a dependency in the
trtl_client manifest. And I can see that the trtl_msgs/ShapeAction.h
file does exist. I don't know why it is not being found.



Platform info:

Linux version 2.6.28-19-server (buildd@rothera) (gcc version 4.3.3
(Ubuntu 4.3.3-5ubuntu4) ) #62-Ubuntu SMP Wed Jul 28 02:58:24 UTC 2010

ROS version: Boxturtle



I have attached my (very simple) sample code. Is this a limitation of
actionlib, or am I missing something obvious?



Thanks,

-Ben
