[Pkg-games-ubuntu] [Bug 993773] Re: Error in RTShaderSystem

[Manuel A. Fernandez Montecelo]

Hi,

CG is disabled in the OGRE package of Debian (and consequently in
Ubuntu, since they take my package directly) to avoid the complications
and packaging burdens of nvidia CG libraries being non-free.

I also seems that the Debian package nvidia-cg-toolkit is badly outdated
and nobody takes care of it, so even if desired, activating it would
take some effort and would need to resurrect the nvidia-cg-toolkit
package to be useful.

So, in summary, I have no intention to enable support for it in the
Debian package.  Maybe somebody will be interested in modifying the
package to include CG support it in Ubuntu, I don't know.

It's easy to take the deb-src package and recompile it in your system,
if you're interested in CG support.  If you have the CG libraries
installed and recompile, probably they're even auto-detected and OGRE
builds support for it automatically.

Cheers.

  Error in RTShaderSystem

  PROBLEM:
  I tried to tun the BasicTutorial 3 from the OGRE website: http://www.ogre3d.org/tikiwiki/BasicTutorial3Source

  I can compile without problems, but when I run the program I get the
  errors described at the bottom and I can see a landscape but wihtout
  textures . The sky is ok, but the landscape is all grey and I know
  that this shouldn't be like that. The same happens if I try to run the
  Terrain demo from the SampleBrowser (see attached screenshot).
