Hi all,

Every once in a while, someone complains on how the database package
in Octave Forge is broken so there is an interest. However, as far as
I know. No one is working on it. Do you want to fix it?

You mention you spent some hours trying to connect to DB. Even without
success at the end, could you maybe write down some of the things you
found on the wiki?

Hi Kris

I also don't know autoconf to fix this. Are you able to submit a patch
to fix this? Or able to convince someone to fix it for you?

About all the other warnings they are all in Octave core and have
already been fixed in dev. There's nothing I can do about them.

The problem is that installing a package requires a proper build
environment and the VS2010 compiler, then comes the trouble. Installation
is quite straightforward using the installer, that shouldn't be a big
trouble. Note that you can select all packages at installation, it doesn't
mean they will loaded automatically by octave at startup (and you can
easily override auto-loaded packages afterwards).

For mingw you should download the sourceforge pkgs archive
(http://sourceforge.net/projects/octave/files/Octave%20Windows%20binaries/Octave%203.6.2%20for%20Windows%20MinGW%20installer/Octave3.6.2_gcc4.6.2_pkgs_20120613.7z/download)
and follow the instructions in the readme.

Re: [OctDev] Install package under Windows

[Greg <ewa...@gm...>]

Yeah, I saw the check-boxes available for the VS2010, but I don't want to
reinstall the whole Octave software to add a single package I didn't needed
when I first did the installation. That's why I wanted to manually install
more packages.

And for the MinGW version, I found no packages. The "pkg list" command says
there is no packages installed. Maybe I'm again doing something wrong?

Hi Leonardo

could you please upload them to
https://sourceforge.net/p/octave/feature-requests/40/ and follow this
there? This things get lost very easily on mailing lists.

But one problem is that demos should be made into demo blocks, not a
separate demo script. Are you familiar with them?

Hello Carnë

linked to.
Hope someone of you guys will do an updated release, the OctaveForge

Both Windows versions of octave contains a large set of octave-forge
packages. If you use the VS2010 version, there's a trick because none of
the bundled packages (but the java one) is installed by default. When
running the installer, when you have to select the component to install,
expand the octave forge section and select the packages you want to install.

you set that within octave by

setenv ("GNUTERM", "windows");

you may want to add this command to your .octaverc file, I do not know
where this is located on windows (on Linux it is in /home/username so I
guess in windows it is something like c:\user\username)

[OctDev] Octave/Gnuplot: set terminal windows

[Greg <ewa...@gm...>]

Hello again for my second question of the day:

I'm trying to use Gnuplot with Octave. After quite a big number of tries, I
found this funny thing:

The command "peaks" typed in Octave compiled with Microsoft Visual uses the
'wxt' terminal, wheras the Octave compiled with MinGW uses the 'windows'
terminal.

The situation is the following: I need to use the Microsoft Visual package,
but I want the 'windows' terminal of Gnuplot.

I have created a GNUPLOT.INI in C:\Users\<user>\AppData\Roaming with the
single line "set terminal windows". It works because after that, running
directly Gnuplot and typing "plot sin(x)" uses the 'windows' terminal.

And the problem is that the "peaks" command still runs Gnuplot with the
'wxt' terminal. It seems that Gnuplot ignores this config file when called
by Octave.

How to change this behaviour and use the 'windows' terminal when plotting
from Octave?


Thanks!

Hi Donjan

the video package is indeed unmaintained at the moment, last release
was more than 3 years ago. Despite no maintainer, some users have
submitted patches to the package so yours no longer applies. Could you
please submit a new one against the dev version? You should be able to
checkout the current devel with:

svn checkout https://svn.code.sf.net/p/octave/code/trunk/octave-forge/main/video

Also could you please submit bug reports and patches to

[OctDev] [patch] octave video package

[Donjan R. <dr...@st...>]

Hi everyone

I've had some video processing tasks and noticed the octave video-1.0.2 
package from OctaveForge has fallen into disrepair. I've emailed the 
designated maintainer Xavier Delacour some days ago but haven't received 
a reply yet, so I hope this is the right place to hand in the patch set.

Most of the work to make it play nice with newer ffmpeg versions has 
been done by Nitzan [1], my fixes make it correctly return NumFrames and 
the file size with newer ffmpeg versions, plus not reject videos with 
odd dimension sizes.

Please cc me as I'm not subscribed to the dev list.

Too soon... I forgot the very obvious options:

- Are you sure the Java package is loaded at all?
If you do (in Octave)
   pkg list

do you see in the output (possibly after scrolling down) a line like:

:
                java *|   1.2.8 | 
...\Octave\Octave-3.6.2\share\octave\packages\java-1.2.8
:

(line wrap!)
i.e., with the asterisk after the package name?
If not (when you don't see the asterisk) you should do (in Octave)
   pkg load java

and try again.

Thanks again. I will try those suggestions and report back to the list. Also, I've wondered whether the space in to 'C:/Program Files (x86)/Java/...' (between Program and Files) is throwing off Octave. I'd noted the warning early on that Octave doesn't like spaces in paths- which is allowed and common in Windows and Mac directories. But I've been assuming that since it's within quotes it's OK.
More soon.

"Intellectual property" is a vague and confusing term. In this case,
it could be a copyright violation, under some jurisdictions.
