The oregonator.cc file doesn't contain a "main" function so it will not
run as a standalone executable.

It is of course possible to write a short main() function to call it. To
call the existing oregonator function, you should be aware that the
DEFUN_DLD macro prepends F to the function name, hence oregonator
expands to "Foregonator", and has a return type "octave_value_list".

To compile using g++ directly, you would need to link to the Octave
library (liboctave) and other libraries on which this depends (such as
libkpathsea). Thankfully, it is no longer necessary to specify all the
libraries manually, the "mkoctfile" script now contains a
- --link-stand-alone option that takes care of the linking and include
paths for you.
