== Errors when running stageros ==
=== Error: Segmentation fault ===

There may be two different types of problems with stage when using certain graphics drivers. The patches below may help some users with certain graphics cards (non-nVidia).

==== Problems with stageros ====

Edit src/stageros.cpp with this change:
{{{
190c190
<     this->world = new Stg::WorldGui(200, 200, "Stage (ROS)");
---
>     this->world = new Stg::WorldGui(800, 700, "Stage (ROS)");
}}}
and then (ros)make. You need to mv/rm ROS_NOBUILD for the make process to actually do something. 

There may be a more elegant way to do this, see <<Ticket(ros-pkg 4462)>>.

==== Problems with Stage ====

On machines with certain graphics cards and certain drivers, rosstage will die on startup with a Segmentation fault (SIGSEGV).  In this case, gdb shows an error inside a gl routine.  Some information, including a possible workaround:

  * http://sourceforge.net/mailarchive/message.php?msg_id=14C30C8B-5BB9-4664-B4C5-1A7939E3E813%40gerkey.org
This problem will hopefully go away with a future upgrade of the underlying Stage library, which has significantly re-written graphics infrastructure.
