[osg-users] Cygwin compiled version from Svn will only load and convert osg files and not gif files - any thoughts?

Hi Brian,

I still wonder why you would want --image for an osg file? You say "it 
doesn't like that for an osg file", but it's actually nonsensical. An 
osg file is not an image... It's a saved scene graph (3D model or whatever).

You need --image when you want osgviewer to load an image file (.gif, 
.jpg, .png, etc.) with osgDB::readImageFile() and map it onto a quad. 
When you don't use --image, OSG will just load the given file(s) (.osg, 
.3ds, .wrl, .dae, etc.) with osgDB::readNodeFiles() and add it as child 
to a group node and display that (if the load succeeds).

As for the crash, as I said I don't use cygwin and have no debugging 
experience there, and little debugging experience on Linux (with gdb) 
for that matter. So I can't really help. Others with more gdb experience 
might be able to suggest some further steps to take.

Good luck,
