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

[Raymond de Vries]

Hi,

I did another test and the output with default settings is (NOTICE):

ViewerBase::configureAffinity() numProcessors=8
   databasePagers = 1
_forceVertexArrayObject = 0
_forceVertexBufferObject = 0
Warning: detected OpenGL error 'invalid operation' at after 
RenderBin::draw(..)
Warning: detected OpenGL error 'invalid operation' at after 
RenderBin::draw(..)
Warning: detected OpenGL error 'invalid operation' at after 
RenderBin::draw(..)
Warning: detected OpenGL error 'invalid operation' at after 
RenderBin::draw(..)
<constantly same lines>

Setting OSG_GL_ERROR_CHECKING=OSG_GL_ERROR_CHECKING does not make a 
difference in output.

Setting OSG_NOTIFY_LEVEL to INFO reveals this part that might be 
interesting:

Created new 0x7fdf1b714510 TextureObject, _numOfTextureObjects 1
OpenGL extension '' is not supported.
RenderStage::runCameraSetUp(osg::RenderInfo& renderInfo) 0x7fdf1b712660

Cheers, hth,
Raymond
