While trying to start Gazebo with the empty world, Gazebo will open up the window for a second, then crash, producing the following error. terminate called after throwing an instance of 'Ogre::InvalidParametersException' what(): OGRE EXCEPTION(2:InvalidParametersException): Named constants have not been initialised, perhaps a compile error. in GpuProgramParameters::_findNamedConstantDefinition at /opt/ros/cturtle/stacks/visualization_common/ogre/build/ogre_src_v1-7-1/OgreMain/src/OgreGpuProgramParams.cpp (line 1423) [gazebo-2] process has died [pid 4498, exit code -6]. log files: /home/dlu/.ros/log/d13697a0-7f0a-11df-ab6d-00016c520afb/gazebo-2*.log The log files are copied below. This is based on the 10.04 precompiled binaries. Does anyone know how to set these parameters?
