install qtoctave with octave 3.2 on 9.10_64 amd

[gerion]

hey everyone, I have a problem installing qtoctave 0.8.2 on Ubuntu64 9.10, amd, with octave 3.2. I have to install from source as the package manager links qtoctave to octave 3.0.

The following error occured during the make process:

Scanning dependencies of target easy_plot

a similar problem occurred trying to install easy plot (not sure if that would fix the first problem):

What I found on the web is
http://osdir.com/ml/debian-bugs-closed/2009-10/msg01388.html
which didn't really help.

The deb package they refer to on http://web.zcu.cz/ftp/mirrors/debian/pool/main/q/qtoctave/ doesn't work, message:
Error: Dependency is not satisfiable: libqt4-network (>= 4:4.5.2)
although the Package manager says that version "4.5.3really4.5.2-0ubuntu1" is installed.

Happy for any suggestions. Thanks

Addition: what does work, is to install octave 3.2 and qtoctave with octave 3.0 from the repository, then set the octave path to 3.2 in the qtoctave configuration.

Is there any way I can install octave 3.2 with qtoctave AND not have octave 3.0 lying around on my HD? Maybe force the removal of 3.0 once qtoctave is installed. Or is there a feature in qtoctave that MUST depend on octave 3.0 being installed and not 3.2?

[gerion]

you can install qtoctave from source, available at http://qtoctave.wordpress.com/download/

However, you might have to use the repository version, see last post at the aforementioned link

I just need Synaptic to somehow recognise that QtOctave can work just as fine with octave 3.2 installed instead of octave 3.0. Is there any place I can report "bugged" dependencies like this to the Ubuntu devs?

[gerion]

no idea how to report outdated dependencies, but I'd assume it'll be updated with a future Ubuntu release.

Don't think the dependencies can be adjusted manually, but pls post it if you find out how.

I managed to successfully compile qtoctave under ubuntu 9.10 and using octave-3.4.2. I had to make 2 changes:
After downloading qtoctave-0.8.2 and extracting it (tar -xzf qtoctave...)
I added the line...

#include <stdio.h>

to the top of the following files:

.../qtoctave-0.8.2/easy_plot/src/gnuplot_connection.cpp
and
.../qtoctave-0.8.2/qtoctave/src/search_dialog.cpp

After this, and under the folder .../qtoctave-0.8.2 I did:
cmake .
make
sudo make install

then I got an operational qtoctave with octave-3.4.2

(This is a great GUI!)

Cheers...

The Debian sid package works if you ignore the dependencies during instalation.

I had Octave 3.2 already installed and downloaded the QTOctave 0.8.2 package from here:

http://packages.debian.org/sid/amd64/qtoctave/download

Then, installed it by brute force:

sudo dpkg --ignore-depends=libqt4-network,libqt4-script,libqt4-sql,libqt4-svg,libqt4-xml,libqtcore4,libqtgui4 -i qtoctave_0.8.2+dfsg-2_amd64.deb

The problem is that the package is declared "broken" by synaptic.

Is there any way out of this? The dependencies are actually fine, but the version name for the QT lib packages is not numeric: "4.5.3really4.5.2-0ubuntu1" and doesn't satisfy the requirement (>= 4:4.5.2).

How can I get synaptic/apt from complaining and attempting to "fix" the broken (not really) package?
