Hello.
I have managed to solve the problem with the 2 warnigs (by removing materials

Great!
Still cant solve the invalid enumerant. I use osgsimplegl3 as it is but with
more simple shaders and seting version to 3.2
What can possibly cause this problem ?
Has anyone run osgsimplegl3 example using opengl 3.2 ?
I can run it with a 3.2 context as long as I also request the compatibility
profile:
traits->glContextProfileMask = 2;
If you don't specify glContextProfileMask, OSG currently does not pass profile
bits to WGL for context creation, and according to the WGL create context
extension spec, a core profile is created in this case.
(You might argue this is a bug. Perhaps glContextProfileMask should default to 1
/ core profile, or 2 / compatibility profile, so that profile bits are always
passed to WGL context creation. If you feel strongly about this, please post a
submission.)
This issue was discussed a while ago by someone trying to run OSG built for GL3
on OSX 10.7, which supports only OpenGL 3.2 forward compatible / core profile.
He discovered that current OSG does not support this. In particular, the OSG
Geometry object does not use a vertex array object, which is required in core
profile. This is the source of one of your GL_INVALID_ENUM errors, and is likely
the one that causes no rendering to occur.
