Hello,
I have installed the scenegraph 1.8.0 alpha from the daily build ,not
sure though if it is properly installed as i have got several errors
while making it.
but after running the sudo make install and setting the LD_LIBRARY_PATH
i got the following output with osg-config
[EMAIL PROTECTED]:~/openSG/opSG$ osg-config

Does that mean it is properly installed?
Then i prepared a MakeFile and my first application (copied the code
from the site)
but got the following error:

what did i miss ?
I am attaching the source code and MakeFile .
The contents of the MakeFile is:
