[osg-users] GL3: non-GL3 version number: 1.0

[Robert Osfield]

Hi Mahmud,

The "GL3: non-GL3 version number: 1.0"  message is being emitted from
OpenSceneGraph/src/osgViewer/GraphicsWindowWin32.cpp, the 1.0 value
suggests that the _traits->glContextVersion is set to one, but this code
block in GrphicsWindowWin32.cpp is for GL3 specific builds of the OSG,
something that is no the default OSG build.

It seems like a GL3 was specifically selected in the build of the OSG, but
then the context version was set to 3 or more  when creating the window so
GraphicsWindowWin32.cpp is raising a flag about it.  Given your uses a 3rd
party SDK that wraps up the OSG, but you say absolutely nothing about what
this SDK is, what version of it, what version of the OSG, then there are
just way too many unknowns for us to be give any advice.

Have you spoken with the 3rd party SDK developers??

Robert.
