Hi!
Im very new to osg, im trying to compile and run a very simple code that use
osg (basicgeon.cpp is attached)
when its gets to the last 3 lines, its crush on the third one
...
osgViewer::Viewer viewer;
viewer.setSceneData( root );
-> return viewer.run();
the project compile properly and crush on runtime,
i set the include and lib directories as needed, and the used lib in
release(osg.lib, osgViewer.lib)
i set the output directory and workdir to \osg\bin so it will find the dll's
im using visual studio 9.0 on VISTA ... (i suspect something with it [Crying
or Very sad] )
i download all the binaries from
http://www.openscenegraph.org/downloads/stable_releases/OpenSceneGraph-2.8/binaries/Windows/VisualStudio9
(extracted the debug files then the release files with 7zip)
i tried in debug too ,still crush(added the d for the required lib files..)
i tried to run the created exe from outside the visual,still crush..
the crush looks like this:

im really dont know what else to do and kinda stuck
thanks alot for any help!
