error: feval: function `unimplemented' not found

[eric]

hello

I'm running ubuntu 12.04 and I'm trying to replace my compiled from source octave3.6.2 by the already compiled 3.6.3 made available in the Mike Miller's repository.

After having uninstalled 3.6.2,
$ sudo apt-get install octave
leads to the error message
error: feval: function `unimplemented' not found

and an useless octave prompt:

octave:1> ls
error: feval: function `unimplemented' not found

I checked my .octaverc and following the bug report  (691311) I checked my liboctave1 version that is 3.6.3 which should work with octave3.6.3.

From now I I'm confused. Any idea ?

thanks

Please be sure to use ppa:octave/stable instead of
ppa:mtmiller/octave. I will be updating that repository to 3.6.4
within the next day or two.

What is the result of "dpkg -l liboctave1 octave-common octave" ?

What is the result of the path command from within octave when it's
giving this error?

Ok, that's dpkg -l. That shows that the octave package failed to
configure when you installed it. What's the output when you run:

$ sudo dpkg --configure -a

? Does it contain the same feval error?

I also asked for Octave's runtime path, what's the full output when you run:

octave:1> path

?

yes,  same "feval error".

Oh yes I missed this one:

Octave's search path contains the following directories:

It appears your Octave m-file path is broken.  You can verify by typing "path" from Octave's command prompt (maybe it still points to the octave 3.6.2 install?).

Check your ~/.octaverc to be sure it isn't setting your path that doesn't work.

You can try to restore Octave's default path to see if that fixes your problem.

Looks to me like something is wrong with the build.

Any reason you're not building Octave yourself?

The reason is the build is already and properly done ! I used it more than once, It's the first time I have trouble with it.

If the build is ok, then I assume something is wrong with your local setup (?)  Try running Octave with the following options

        octave --no-site-file --no-init-file

Please try the following now, completely uninstall octave and install
again from the PPA. I'm not sure why the arch-independent parts of the
path are not being found, if octave-common is indeed installed
correctly.

$ sudo rm -f /var/lib/dpkg/info/octave.p*
$ sudo apt-get purge octave liboctave1 octave-common
$ sudo apt-get update
$ sudo apt-get install octave

This should install 3.6.4 now, the PPA was updated over the weekend.
Let us know if this still does not work.

Do you have the old Octave package still installed? Is there any
octave3.2-* package around?

There is no need to recompile Octave in this case, unless you want to
contribute to global warming by burning some CPU cycles.

This command seems dangerous. Why would anyone ever manually delete dpkg's data?

If that command helped you, there's a packaging bug. Please report it.

Maybe. The octave.postinst script runs "pkg rebuild", which I suspect
was failing with the feval error reported, because for some reason the
pkg command, and all other commands under /usr/share/octave, were not
being found by this install. That's the root problem that I don't
think we can answer without being able to reproduce this. Maybe
/usr/share/octave/<something> had been moved or removed through some
means other than dpkg, maybe a manual rm or a "make uninstall". Should
the octave package be robust enough to handle users doing things like
that?

We should see if Sébastien's 3.6.4-1 upload fixes this issue.

Also, we should revisit the whole problem of using rpath in liboctave
and friends, right?
