Hi all,
for fg osg with osgviewer enabled and a camera configured in preferences.xml
that can't be opened, fg coredumps.
This is due to using the GraphicsContext for the camera without checking if it
has been created:
osg::GraphicsContext* gc;
gc = osg::GraphicsContext::createGraphicsContext(cameraTraits.get());
gc->realize();
Attached is a patch (against current cvs) to fix this.
Please consider applying this patch, it works perfectly for me.
Greetings, Torsten
