Osgviewer cow does not view a cow?


I installed OpenSceneGraph 3.0.1using MacPorts.
I've tried osgversion -> OpenSceneGraph Library 3.0.1. I downloaded the OpenSceneGraph-Data.
Everything seems working well than osgviewer cow.osg takes hours without viewing anything !
please I need help ? is there a way to debug ?
Make sure you have defined the OSG_FILE_PATH environment variable and that it points to the data directory (the one with 'cow.osg').
You can then set OSG_NOTIFY_LEVEL to DEBUG_INFO to get extended information printed to the console. If for any reason the file could not be loaded correctly you will see where to start to troubleshoot.
You can also try to run
$ osgviewer --image /path/to/an/image.png
to test if the plugins work correctly.
Plugins are named e.g. osgdb_jpeg.dylib so you can look for these to make sure they have been built properly along with the core libraries and programs.
Try setting the notify level to DEBUG : Tips And Tricks
$ export OSG_NOTIFY_LEVEL=DEBUG
and run it and see if it says what's going on/going wrong.
