Re: [Playerstage-developers] Simulation interface in libplayerc is close...

[Douglas S. B. <db...@br...>]

I was wrong about the PLAYER_SIMULATION_SET_POSE2D value; stg_driver.cc isn't
even used it appears.

But it looks like there is a missing line in Stage's InitSimulation() of
player_driver.cc. In order to find the simulation device, it needs to be added
to the devices:

  g_ptr_array_add( this->devices, device );

After adding this line (with the patch posted at the tracker) I can now find
the simulation device. I see:

Stage: received request to move object "Pioneer" to (0.00,0.00,0.00)

Pioneer is the name of the robot I am trying to move. After this point,
however, I get a segfault.
