Greetings, I'm trying to install gazebo and ROS at my Ubuntu 11.10, But I'm getting some errors after I try to run roslaunch gazebo_worlds empty_world.launch , this is what I get:


gazebo: /home/k/Programs/ogre_src_v1-7-4/OgreMain/include/OgreSingleton.h:80: Ogre::Singleton::Singleton() [with T = Ogre::TerrainPageSourceListenerManager]: Assertion `!ms_Singleton' failed. [gazebo-2] process has died [pid 13366, exit code -6]. log files: /home/k/.ros/log/87ad5d8a-600e-11e1-ab32-0024d690acd8/gazebo-2*.log


The above mentioned log does not exist in the given folder. :(

So I tried running gzserver and then gzclient, which rendered:


k@k-Inspiron-1545:~$ gzclient Gazebo multi-robot simulator, version 1.0.0-RC2 Copyright (C) 2011 Nate Koenig, John Hsu, Andrew Howard, and contributors. Released under the Apache 2 License. http://gazebosim.org

Throwing exceptions from an event handler is not supported in Qt. You must reimplement QApplication::notify() and catch all exceptions there.

There are no formats supported (no codecs registered). in Codec::getCodec at /build/buildd/ogre-1.7.3/OgreMain/src/OgreCodec.cpp (line 69) Aborted k@k-Inspiron-1545:~$


But freeimage has been installed, shouldn't it be working?

Thanks in advance!

This looks like a gazebo issue. I suggest you ask on http://answers.gazebosim.org
