56.72 drivers work

[seed]

this may be 3 days too late, but the nvidia 56.72 drivers are out and using the registry hack to enable the glslang support, i got the 3d labs brick and particle shaders working as well as the humus' volume lighting demo displaying the flames properly.

Which hack did you use?

This one

didn't worked for me...

latest nvemulate(with GLSL support) works well on 56.72(but it is still early implementation)..

i can't get working particle demo. it writes "No such uniform named "Time""

[seed]

yeah, i did use the same hack as the one from that link. the particle demo is giving me some kind of an illegal operation, but it does display some random noise on a quad. maybe it is not fully working at this stage...don't have an ati card to test it on, only nvidia here and at work.

just had a look at the source and the error i am getting, and it is the uniform error for 'Time'. my best bet is that the nvidia drivers do not have support for uniforms yet (i may be wrong)

The 56.72 drivers have support for uniforms and most of what was missing. It's quite usable now. I do have one problem though. I can't compile shaders without a main(). Has anyone tried this? No matter what I do in the shader, if there's no main() I get a "no program defined" or sth. Note, this happens at compilation.

What I'm trying to do is put some flags in one shader and use them in another to conditionally use or not use parts of the second (at linking time of course).

GLSlang shaders need the main() entry point. its in the specs .

If I remember correctly, the specs say that a shader -program- needs a main(). A shader -object- need not define a main(). Of course, as long as there is a main() in one of the shaders (of the same type) at linking time. Am I wrong?

[Corrail]

Yes, you're right, spasi.
There's no need to define a main() in every shader object. But there HAVE to be a main() in a shader program. If not the link won't be successful.
