I am getting the following error while running osgvolume.exe with
--shader parameter.
Adding ""#version 110" on top of the vertex shader code resolves the
error. But what about fragment shader problems...
I am using OSG_RELEASE.2.1.5 with NVIDIA 8800GTS card
glLinkProgram "" FAILED
Program "" infolog:
