There are many directories that need to be included in the library
search path to compile C++ files for Octave:

~ -L${OCTAVEPREFIX}/lib/octave-${OCTAVEVERSION} -loctave -lcruft
- -loctinterp -Wl,--rpath,${OCTAVEPREFIX}/lib/octave-${OCTAVEVERSION} -ldl
- -lm -lncurses -lkpathsea -lreadline -lblas -llapack -lfftw -lg2c

However, the script "mkoctfile" usually takes care of all this for you
so you would normally just type:

mkoctfile hello.cc

and the file hello.oct would result.

I am not entirely certain whether version 2.0.17 includes the mkoctfile
script, but you would probably be better advised to install one of the
more recent 2.1.xx series versions if you are going to be using dynamic
functions. The latest of these (2.1.51) can be downloaded from
ftp://ftp.octave.org/pub/octave/bleeding-edge
