Using octave libraries

[Edward S. Meadows]

I'm trying to use the Matrix-Vector class libraries from
octave.  My first attempt fails to link.  I'm evidently not
linking to all the necessary libraries.  Can someone advise
me as to where the missing references come from?

I can guess that some of this comes from readline and some
from kpathsea.  Is it really necessary to link to those to
use the octave libraries? 

Thanks for any tips.
