First I run the turtlebot run launch file from the terminal:

    $ roslaunch turtlebot_gazebo turtlebot_world.launch

Then in a new terminal:

     $ rostopic echo /scan

As soon as I subscribe to the /scan topic i get the following error:

gzserver: /build/ogre-1.9-mqY1wq/ogre-1.9-1.9.0+dfsg1/OgreMain/src/OgreRenderSystem.cpp:546: virtual void Ogre::RenderSystem::setDepthBufferFor(Ogre::RenderTarget*): Assertion `bAttached && "A new DepthBuffer for a RenderTarget was created, but after creation" "it says it's incompatible with that RT"' failed.

Hi @inani47, did you manage to fix that ? I am having the same issue of gazebo crashing with no reason when launching it with ros and this version of Ogre.

@monabf sorry for the late reply. I was able to resolve the issue by updating to a newer version of Gazebo. All the best!

To expand - I also got around this by updating to a newer version of Gazebo (I'm running Kinetic on Ubuntu 16.04).

I followed the "Alternative Installation" instructions here (with an important exception noted below): http://gazebosim.org/tutorials?tut=in...

IMPORTANT NOTE - if you're on Kinetic, you want to install "gazebo7" NOT "gazebo9" (which would be for Melodic)

Hope that helps - I spent many hours on Google figuring this out. But now the examples in Chapter 7 of Programming Robots with ROS run (as far as I've tried).

Cheers, /K
