It seems that the black screen problems are not related to the freeimage messages.
I get rid of the messages just using colors instead of textures but still not working.

For the record, OpenGL is working, I use the onboad G33 chipset video card, intel drivers.

Yep, DevIL should solve the problems mentioned in the Ogre.log file

sure about that, it was just a suggestion..
In my case the Ogre samples were working, too, because they use PNG
textures instead of JPEGs.

You can find more information on the texture problem in the Ogre forums,
freeimage links libpng, libjpeg etc statically but exposes all  the
symbols, another part of the program (can't remember which right now...)
uses them as shared lib and if the library versions (installed shared
vs. statically linked) don't match this will cause problems (then only
the order of linkage determines, which symbols are used...).

But as I said, your problem might be totally different.. did you have a
look into your ogre.log file though? glxgears  working / glxinfo output
ok? Which OpenGl drivers do you use?

I found the email, you mean that you only got a black screen with
freeimage but worked fine when you switched to devil or are you talking
about other problem?

Did you try Ogre without freeimage (configure --without-freeimage) and
with DevIL instead, as already proposed by Sandy? This should solve the
libjpeg errors in the Ogre.log and worked fine for me.
I had everything running on a fedora 7 64bit system (2x intel xeon) some
weeks ago.

Good news! I got bitten by the black screen error :D

I have managed to obtain a core duo 2 computer, installed fedora core
64bit version and got the black screen.

Good news because now I can start hunting that bug properly.

Hi nate,

I tried to reduce the camera resolution to 320x240, even to 160x120, but

nothing changed. I have to say that early revisions of Gazebo (I don't
remenber exactly, 126/153) worked well.

By now, find enclosed 'glxinfo' and ' Xorg.conf' files of the following
system:

OS: Fedora 8
CPU ID: GenuineIntel: Intel(R) Core(TM)2 Duo CPU T7100 @ 1.80GHz
GL_VERSION = 2.1.1 NVIDIA 100.14.19
GL_RENDERER = GeForce 8600M GS/PCI/SSE2
Thank you,
