Does your application use Qt? If so, then that could be (at least) part
of the issue. It's been a while since I've tested it out, but I've
always had to use SingleThreaded with Qt.

Hi All,
I had been running my app based on OSG 2.8.3 on a VS2003 build (XP machine) for
a while. However, I'm now moving the app to VS2008 so, I got a clean 2.8.3
source, pulled the latest 3rd party VS2008 binaries and configured CMake to
build it. No problems with the build.
(NOTE: Not ready to move on past 2.8.3 yet)
When my code is ported over and the OSG libraries are added in, when app starts
up, if my derived CompositeViewer exectues the line:
setThreadingModel(ViewerBase::CullDrawThreadPerContext);
(which was in the original VS2003 2.8.3 build and it ran fine) with VS2008, it
immediate crashes at the start of the frame being displayed.
If however I replace it with
setThreadingModel(ViewerBase::SingleThreaded);
the app will run but as a single thread which isn't all that desirable as all
work stops if I pop up something (e.g. user dialog).
Is there something I forgot, I didn't see anything specific in the CMake
listing regarding enabling threading (the one reference to OpenThread is set
for dynamic).
Thank you for any insight you may be able to offer!
Cheers,
Tom
