I did just this and went to 2.1.30. Big success: "hallo.cc" works
perfectly. But the oregonator does not want to become an oct-file
on my computer:

bash-2.01$  mkoctfile -v oregonator.cc
c++ -c -fPIC -I/usr/local/include/octave-2.1.30 -I/usr/local/include/octave-2.1.
30/octave -I/usr/local/include -fno-rtti -fno-exceptions -fno-implicit-templates
 -g -O2 -Wall oregonator.cc -o oregonator.o
oregonator.cc: In function `class octave_value_list Foregonator(const octave_value_list &, int)':
oregonator.cc:15: conversion from `Array<double>' to non-scalar type `ColumnVector' requested
bash-2.01$ 

The offending line is

  ColumnVector x = args(0).vector_value ();

Can anybody explain what this means? 

Thomas Hoffmann.
