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

[Manuel A. Fernandez Montecelo]

Traditionally in Debian systems, not all options are enabled by default
if they happen to contain or require non-free pieces of code; or some
other problems.  For example, Adobe Flash or some drivers are not
supported or are kept in non-free.  I would hardly call Firefox faulty
and that shouldn't be shipped in a release for not being able to show
some pages with flash content.

I don't know what's Ubuntu policy on that, but anyway I'm not involved
in Ubuntu -- they just happen to import my package directly.  If they
ship a version of a software without 100% coverage that everything works
perfectly, it's probably due to lack of manpower.  Help is welcome.
Every software company or group release software with problems
sometimes, even if they only ship core-OS software and not the gazillion
of software that Debian, Ubuntu and other distros support; and most of
them are mostly (or completely) run by volunteers.

Other than that, OGRE is quite functional for many purposes, and
especially for games that we plan to use inside Debian.  If you
want/need a especial version, it's very easy to recompile and get things
working.  Just install libCg, download the source deb, and re-run
debian/rules.

Cheers.

Title:
  Error in RTShaderSystem

Status in “ogre” package in Ubuntu:

  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).
