[osg-users] OSG in Gtk3 GLArea

[Mean Taipan]

Again, my apologies but I can't delete this account.  Moderators, please do it ASAP, no problem for me.  (I won't try creating a new account until then, since I need to use the same email).

But in the meantime, if you'll bear with me, I recompiled osg with -DOPENGL_PROFILE=GLCORE but it triggers


Code:
Warning: detected OpenGL error 'invalid enumerant' at after RenderBin::draw(..)



if there is any geometry.  Vastly fewer errors than before, in fact only one, but still a black screen.  So I'm probably missing something.  The sequence of events is:

- when constructing the Viewer subclass, when the window is realized, it calls setUpViewerAsEmbeddedInWindow().
- when it is time to render, Gtk has already made the GL context 'current', so the draw callback just calls Viewer::frame().

So, if it's not too much trouble, someone please point out how I can get some finer debug granularity so I can chase down the error myself, or advise on what needs to precede the frame() call.

Regards,
SJH
