'ode45' is a function from the file /home/tatsu/octave/odepkg-0.8.5/ode45.m

fvdb = @(vt,vy) [vy(2); (1 - vy(1)^2) * vy(2) - vy(1)];
           vopt = odeset ("RelTol", 1e-3, "AbsTol", 1e-3, \

           ode45 (fvdb, [0 20], [2 0], vopt);

The above works for me.

For me the release segfaults when loading dldsolver.oct into Octave
4.0, so it segfaults already during installation. Apparantly this is
not reproducible everywhere.

I'd still suggest that this release should not be published at OF, in
particular because the hope was vain that these problems are only a
short passing state. But if some _user_ of odepkg has a different
opinion, despite everything told in this thread, I'll publish it


The odepkg I use was installed with an earlier version of octave, before the pkg was moved to unmaintained. It seems to work OK.

I can not rebuild the package with the current version of octave. Most of the problems stem from changes within octave and gcc. I see
feval needs to be octave::feval
is_xxxxx needs to be isxxxxx for several different functions
   xxxxx = empty, etc.
config.h is included but should not be
some problems in macro expansion for F77_FUNC

Maybe too much to fix, at least for me.  I am unable to maintain the odepkg.
