Update again, as of this writting we are at 243 revision.
Both should not segfault but both worlds have issues.
The simplecar is meant to be experimental, the wheels are not even aligned (if you fix it and give it a proper body, please send it to the patch system)

hi

Well, the black screen error is resolved. Thank you everyone for helping. Well, I couldn't find /tmp/OgreAdaptor-HEAD.3.cc file.

But from observing the output of the diff, I added selectedRenderSystem->setConfigOption("RTT Preferred Mode","PBuffer"); to the OGREAdaptor.cc file. For some reason the default mode seems to be RTT, which doesn't seem to work, as I had written in my previous mails.

I would request the authors to add this line for the next update as others might face this simple problem as well.


I am using th latest svn release (233).

Another problem that I am facing is with

Hi,

I faced a similar (?) error and found out that, in my case, it was caused by the following bug:
http://www.ogre3d.org/phpBB2/viewtopic.php?t=38037

..after downgrading my nvidia to a 100-something version, everything worked fine again.

I am not sure, whether you have the same problem, but just in case, give it a try :-)

cheers,
