Hi Gopal,
00:02.0 VGA compatible controller: Intel Corporation 945G/GZ Express Integrated
Graphics Controller (rev 02) graphics card.................
Yeah, that isn't going to work with osgOcean in its current form. We
could possibly check for a set of extensions we know we need
(EXT_FRAMEBUFFER_OBJECT, the various shader extensions, etc.) or a given
OpenGL version, and then disable most shaders and effects if these are
not found. That would give you a straight ocean surface that would
animate but which wouldn't have reflections, refractions, underwater
depth of field and so on.
You could possibly modify the oceanExample's application.cpp to disable
all effects (reflection, refraction, depth of field, god rays, glare,
distortion, silt), then recompile it and try to run that. It might work,
but the ocean surface might look weird because the shaders will try to
compile and probably fail. osgOcean really needs to detect this kind of
card and set itself up correctly to run in "reduced mode" in that case.
I'll be working on this in the next few weeks (our own clients need to
run an app that uses osgOcean on various graphics cards, some of which
are similar to what you mention above) so if you can wait a bit, I'll
send a word to the mailing list once it's done so you'll be able to test
again.
I would really like to get the list of extensions your card supports.
The easiest way to get that is to do this on the command line, as Kim
mentioned:
export OSG_NOTIFY_LEVEL=DEBUG
osgviewer cow.osg > output.txt 2>&1
and then press Escape as soon as the cow shows up, and send us the
resulting output.txt file on this thread. That will contain valuable
information that will help me design the tests needed to detect
situations similar to yours correctly in the osgOcean code.
About your backtrace:

Weird that it's crashing in the create context... Do other OSG examples
run well? For example just run
osgviewer cow.osg
Does that run well? If not then try to update your graphics driver,
because creating a graphics context is a basic operation that all
graphics apps will need to do and if it's failing, then you have a
bigger problem than osgOcean not running...
But in any case, this is not related to what I said above about your
card probably not being able to run osgOcean at all in its current form
because it does not support the features osgOcean was designed for.
Hope this helps,
J-S
