Hi, I am an user with same problem.
I'm trying to compile a advanced GLSL program to improve performance.
The problem on  file  OffsetMapping_specular.asm with normalmap examples of 
OGRE library

My graphic card is a NVidia GeForce GTS 250 and i'm using Ubuntu Studio 10.04 
operation system.

The complete log of file is this (additional information):

I was watching the live streaming of the BConf speech about naali/realXtend.
Their projects are BSD license style and have a Cg supershader with support for 
difuse/normalmap/parralax/reflexion shader and blender exporter.
https://sim.lorea.org/pg/pages/view/138/

On the Gamekit Thread on BlenderArtists guru said he had a patch for Cg 
compositing filter with a working SSAO fragment program and was working on 
using this for deferred shading. I invited him to post his patch here.

BA is down for the moment, I will post the link later.

I was wondering what was the current status for the GLSL Support.

Thanks in advance!

Original comment by Silverk...@gmail.com on 3 Mar 2011 at 2:28

[GoogleCodeExporter]

Currently, GLSL can be supported by custom Ogre material script.
You can see HLSL sample here, Samples/Runtime/Samples/OgreNormalHLSL.blend

I have a plan that integrate Ogre1.8 RTShaderSystem to OgreKit.
If it is done, some shader features can be support likes a normal map display 
without custom Ogre material script.

Great! Thanks for the feedback!

Original comment by Silverk...@gmail.com on 3 Mar 2011 at 6:43

[GoogleCodeExporter]

Unfortunately the sample mentioned by harkon.kr doesn't work for me.
After setting the engine to 'Gamekit' and the runtime path to:
./OgreKit/OgreKit-NoDX.exe

I get the following error:
"BlendLoader: Ogre exception: Cannot locate resource 1PerPixel.material in 
resource group General or any other group."

I'm working on Windows 7 with "Gamekit-blender-2.54-beta-windows32-4" and the 
latest SVN checkout (861).

Original comment by yout...@amaasbier.de on 15 Mar 2011 at 12:55

[GoogleCodeExporter]

You should run with OgreKit.exe & d3d renderer, not OgreKit-NoDX.exe.
OgreNormalHLSL.blend is a HLSL sample, not GLSL.

OgreKit-NoDX don't have d3d renderer & below r790 in download sections.

Try with r851 runtime in OgreKit-Samples-Bin-Win32(r851).7z.
