Yes.
The oregonator.cc file that I sent is a standard Octave (only) example, i=
t=20
should compile. That's best to ask for help in the Octave  mailing lists.=
=20

Please supply the octave version, OS version, cc compiler, etc. Run octav=
e,=20
type "octave_config_info", and send the results to the list, "complaining=
"=20
that you can't compile oregonator.cc

Luck!

PS-your octave was built with dynamic libs, wan't it? Search for "dld =3D=
 1"=20
and "--enable-shared" in the above 'octave_config_info' command output.
