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

[Robert Osfield]

Hi Stev,

I don't have access to a OSX box so can't test things myself so have
to rely upon others in the community who have OSX machines to doing
testing and esnure things work sweetly, and if things break spot them
as early as possible so we can pin point when the problem first
emerged, which then leads on to figuring out how to address the
problem.

The GL error and dynamic_cast errors are likely unconnected and at
this stage I don't have an explanation for either.

For the GL error could you enable fine grained test for GL errors by
setting the env var OSG_GL_ERROR_CHECKING to ON.  Then re-run the
test.

Also could you provide information about what OSG application and test
models you are using to the warning, if other combinations do work OK,
then information about this is useful too.

--

The dynamic_cast<> error doesn't mean much to me as I don't have any
clues to what context this has.  Is this a compile error? A linker
error?  A runtime error reported to the console?

--

Another approach to the pinpointing the causing problems would be to
step back to versions of the OSG between 3.4 and git master's head.

Finally, perhaps others in the OSG/OSX community can pitch in with
testing to see if a pattern emerges to what works and what doesn't so
you pin point what is causing the problem.

Robert.

No problem on my Windows machine.  I also tried compiling on my 2013 MacBook Air with the same results and errors.  I did not have it when I was using OSG3.4.
