Hi,

sorry guys for the late answer. Yes this one should be considered invalid as it is due to a problem in the external package installation process.
I want to explain how to overcome the problem so other ubuntu users can solve it as well. This library relies in some .oct files that don't get compiled/deployed appropriately. So what you have to do is to build them yourself by using 'make' and once you got them put them in the path so the pararrayfun/parcellfun can find them.

Thanks for taking a look,

Alberto.

AFAIU this is not a bug in parcellfun/pararrayfun but the effect
of modifications done by debian/ubuntu package maintainers
to how pkg.m works on debian derived systems.

essentially on a debian/ubuntu system invoking pkg from within
octave does not really work, you should use your system package
manager instead, e.g.:

sudo apt-get install octave-general

I personally don't agree with this approach, if you do not either you can

1) Build Octave from source instead of using the .deb package with patched pkg.m

2) Complain with the package maintainers and convince them that this should be done differently (but this is gonna be very hard).

I'm tentatively marking this issue as "invalid", as it seems it should be fixed elsewhere.
if anyone disagrees please feel free to reopen the bug.

Hi,

I have downloaded Octave 3.6.1 through apt-get in Ubuntu and installed package general-1.3.2.tar.gz by issuing 'pkg install general-1.3.2.tar.gz' from the console.
When I try to use pararrayfun, everything goes fine until the processes are finished. I'm having problems with the _exit_ call which is a wrapper of the POSIX call(http://octave.sourceforge.net/general/function/__exit__.html).
This is the log I'm getting,

warning: parcellfun: unhandled error in subprocess 1
warning: parcellfun: unhandled error in subprocess 2
error: `fload' undefined near line 310 column 16
warning: broken pipe -- some output may be lost
warning: broken pipe -- some output may be lost
error: `__exit__' undefined near line 283 column 1
error: `__exit__' undefined near line 283 column 1
error: called from:
error: called from:
error: /usr/share/octave/packages/general-1.3.2/parcellfun.m at line 283, column 1

It works fine in Octave 3.2, but I don't wanna use this version.

Thks.
