Hi all,
I have a GeForce 7900GTX at home, and out of curiosity I wanted to try
out the osgdrawinstanced example. The first time I ran it I got:
glLinkProgram "" FAILED
Program "" infolog:
Vertex info
-----------
0(6) : warning C7532: global variable gl_InstanceID requires "#version
130" or later
0(6) : warning C7011: implicit cast from "int" to "float"
0(6) : warning C1059: non constant expression in initialization
0(10) : warning C7011: implicit cast from "int" to "float"
0(6) : error C5108: unknown semantics "INSTANCEID" specified for
"gl_InstanceID"
OK, so it looks like the draw instanced extension is at least supported
in my GL driver, and the first warning at the top is easy enough to fix,
and I thought that would fix the error (unknown semantics) too, so I
added #version 130 to the top of the shader. Re-running, I got:
glLinkProgram "" FAILED
Program "" infolog:
Vertex info
-----------
0(19) : warning C7533: global variable gl_ModelViewProjectionMatrix is
deprecated after version 120
0(19) : warning C7533: global variable gl_Vertex is deprecated after
version 120
0(7) : error C5108: unknown semantics "INSTANCEID" specified for
"gl_InstanceID"
So the error is still there. (on a side note, cool, it's the first time
I see the GLSL 1.3 / OpenGL 3.0 deprecation warnings :-) )
Does anyone know what would cause this? Is the draw instanced extension
just not supported for 7xxx class cards? I have a 9800GTX+ at work so
I'll try there, but I was wondering.
Thanks in advance,
J-S
