Image package on octave fails due to unsatisified dependencies

Yamen Ajjour
I have Octave 3.8.4 installed on Linux mint 17   when i try to install
image package on it

using pkg install -forge image

i got the following error message

error: the following dependencies were unsatisfied: image needs octave
 >= 4.0.0

i tried to compile the octave source by myself and reinstall it using
the same command it didn't help .

I tried also to install octave-image using apt-get this also did n't
make the trick after installing the package i tried to call hough and it
still complains that i have to install image package !

Hej! Octave 4.0 will be released very soon and thats why a lot of packages from Octave-Forge got updated lately; so they're compatible with internal changes to Octave's core. Your installation fails because you try to install the most recent version of image that requires Octave 4.0 but you use version 3.8.

You have two options:
1) You try to compile Octave 4.0 by yourself (you can find the sources here: ftp://alpha.gnu.org/gnu/octave/) -- as there is no prebuilt binary in the repositories available yet -- and then install image via pkg install -forge -auto image.

2) or you simply use an older version of image. Check out http://octave.sourceforge.net/image/index.html and and then go to NEWS and you'll see that 2.2.2 was the previous version. You can find the corresponding file (i.e. image-2.2.2.tar.gz) here: http://sourceforge.net/projects/octave/files/Octave%20Forge%20Packages/Individual%20Package%20Releases/ Inside of Octave you need to move into the folder where you downloaded the file to (via cd /home/YOUR/PATH) and then you type pkg install -auto image-2.2.2.tar.gz. The option -auto makes sure Octave loads the image package on startup.

Maybe a third option for you:

If have Windows you can also use the prebuilt windows installer: ftp://alpha.gnu.org/gnu/octave/octave-4.0.0-rc4-installer.exe followed by pkg install -forge -auto image.
