[Playerstage-developers] Writing Interface Problem

[Michael K. <me...@gm...>]

I am trying to write a new interface and driver to support a pan tilt
servo mechanism. I followed the steps for writing a new interface
outlined in http://sourceforge.net/mailarchive/message.php?msg_id=3D9208671=
.
However, when I try to build the driver I am getting the error
messages:

error: `player_servopt_data_t' undeclared (first use this function)
error: `player_servopt_cmd_t' undeclared (first use this function)

I used the Makefile provided in the example plugin driver folder. I'm
using Player 1.6.4. Any ideas what the problem is?

Thanks

Mike
