[PlayerStage-Gazebo] wxgazebo: waiting for data?

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

Friends of Gazebo,

I'm trying to run Gazebo-0.6.0-rc1 (from tar.gz) on FC5 with
Player/Stage 2.0.2 (out of CVS). I have installed GDAL (but not Proj4 or
Lib3ds). I'm running with Livna nVIDIA drivers, and everything compiles
fine. All looks good until:

$ wxgazebo /usr/local/share/gazebo/worlds/pioneer2at.world
starting server
waiting for server
connecting to server
opening simulator interface

waiting for data

And it never does anything besides this. I tried starting player, and
then playerv, but no window appears. Strangely:

I think I just got a clue. /var/messages says:

Looks like gazebo and libode are triggering something in SELinux. Anyone
know what special "chcon" commands I might need to run? I'll try turning
SELinux off too to see if that helps... at least temporarily...
