problem during executing Hydrax

Dear All
Using Hydrax, (with VS 2008), when I create Hydrax, I get the following error:

OGRE EXCEPTION(2:InvalidParametersException): Named constants have not been initialised, perhaps a compile error. in GpuProgramParameters::_findNamedConstantDefinition at f:\codingextra\ogre\shoggoth_vc9\ogre\ogremain\src\ogregpuprogram.cpp (line 1087)

Debugging the code I found the error is raised in this line:
FP_Parameters->setNamedAutoConstant("uEyePosition", Ogre::GpuProgramParameters::ACT_CAMERA_POSITION_OBJECT_SPACE);


I try to use CG, GLSL, HLSL but nothing change
Have you any suggestions?

Thanks in advance,
Corrado.

Use HLSL or CG mode with DirectX render system. It should work. (For OpenGL render system, use the latest CG version from Nvidia and Hydrax CG mode).

Hello,
I've already try to change it but I've got the same message

Does the precompiled demo work for you? If it doesn't then your graphic cards mustn't support SM 2.

No, the precompiled demo doesn't work. I tried it on thre different pc, with Nvidia 256 mb, and I got the same error.

If the precompiled demo doesn't work the only reason is: Your graphic card doesn't support SM 2.0, you haven't latest drivers(Anyway must work with any recent version).
