Hi Michael,
can you show the code calling the TSG and assigning the vertex attributes?
Usually you will have to to a high vertex attribute like 7 or 8, since
the lower numbers are mapped to the fixed function pipeline attributes.
I can check my code when I'm on my development machine again.
Which version of osg are you using?
Cheers

I've researched deeper into my normal maps not working after fixing
those shader errors that have been reported under OS X, and found out
that in my pass1VS ( http://goo.gl/sT7m7n ) Tangent attribute is
always (0, 0, 0). I get it from osgUtil::TangentSpaceGenerator.
Any clues?
Thanks.

Hi Michael,
The shader code seems indeed to be faulty and I found the errors
generated quite appropriate. Maybe your driver in the Linux is
quite sloppy and uses some extensions. Nvidia for instance allows
all sort of non-standard functions ( hlsl saturate etc.)
I usually use ATI Shader Analyzer. It seems to stick to the GLSL
specifications very tightly [1].
Unfortunately I'm on vacation and don't have my developer laptop
with me, so I cannot check directly.
