[osg-users] Master renders with OpenGL error on OSX

[Raymond de Vries]

Hi Robert,

Ouch, typo, I meant to set the OSG_GL_ERROR_CHECKING properly...

I am afraid this won't provide more info neither:

MB:~ ray$ env | grep ONCE
OSG_GL_ERROR_CHECKING=ONCE_PER_ATTRIBUTE
MB:~ ray$ env | grep NOTIFY
OSG_NOTIFY_LEVEL=NOTICE
MBAngela-3:~ ray$ osgviewer cow.osg
OSG_VERTEX_BUFFER_HINT set to VERTEX_ARRAY_OBJECT
ViewerBase::configureAffinity() numProcessors=8
   databasePagers = 1
_forceVertexArrayObject = 0
_forceVertexBufferObject = 0
Warning: detected OpenGL error 'invalid operation' at start of 
State::apply()

When I have more time, I will dig into it more. Do you have other 
suggestions in the mean time?

Cheers
Raymond
