GLSL linking problem (C9999)
Author
i'm having a little problem with glsl...
when i use the gl_LightSource[0].position, for example give me a link error...
(20) : fatal error C9999: not a leaf in member select (39)
I look everywhere for a error table of the glsl compiler with no sucess. So i'm really stuck with this error.
And the strange thing is , if i made a typo, for example: gl_LightSource[0].posiion ( without the t ) the compiler complain that there is no posiion on the glLightParameters...

hum... sorry... i forgot to mention... i have tryed this...
if i put, for example.. gl_LightSource[0].position.lll gives me a compile error as expected... but a gl_LightSource[0].position.xyz gives me a link error...
The mistery to me is that it's ocurring a link problem, not a compile error...
but thank you for the suggestion...
just editing to mention that the line thar the linker indicate the error.. is the last line of the file...
i'm really inclined to believe that may be a problem with my driver...

The shader looks fine (well, it compiles and links with a default fragment program in RenderMonkey), so the error might be in your attach/link code?
Author
well... i was using forceware 77.77... and i upload it to 81.something :) and now it's linking without errors...
but thank everyone that tryed to help :D

You're GLSL probably didn't support ftransform() or gl_Frontcolor. I don't know, but good thing it's working now. =D
