Dear user

I am puzzled by a problem with the optim package. the reply of Octave to

pkg load optim
demo lsqcurvefit

lsqcurvefit example 1: failed
'__nonlin_residmin__' undefined near line 83 column 20

It seems that all functions in ~/octave/forge/optim-1.5.5/private
can not be found. This is on an Ubuntu 14.04 system with Octave 4.03.
On a sibling system the above works just fine!

Can somebody give me a hint on how to tackle this puzzle?

With best regards


The demo works with octave 4.0.2, optim pkg 1.5.1. Looking at sourceforge, the latest release is 1.5.1.

"/octave/forge/optim-1.5.5/private" looks strange. My optim package does not have 'forge' in its path.

I see
