pkg install -forge [library-X-X]

[John Hayes]

Hi all,

I’m sorry if I’m missing how to do this and it’s perhaps very simple, but I was 
wondering if there is a way to specify the specific version of an Octave-Forge 
package and draw in its’ respective dependencies (automagically) or even 
install a particular version of a single package by version number assuming the 
previous dependencies have been satisfied. 

I’d prefer not to use Octave 3.8.0 routinely quite yet (I hope to debug the 
problems I’m having with it in more detail later), while when I do something 
like this in Octave-3.6.4 I get the below:

> octave:1> pkg install -forge image
> error: the following dependencies where unsatisfied:
>    image needs octave >= 3.8.0
>  image needs signal >= 1.2.0
>  image needs general >= 1.3.0
I’m using the following webpage as reference, but maybe there’s something I’m 
missing in the normal use-cases:
http://www.gnu.org/software/octave/doc/interpreter/Installing-and-Removing-Packages.html

Based on the above dependencies, I was expecting/hoping the following might 
work:
> octave:1> pkg install -forge image-2.0.0

Presumably, that’s the correct image version to install for 3.6.4 octave but 
that doesn’t seem to work either (and I’d still presumably have to 
import/install each dependency manually)? 

I guess I’m wondering: is the -forge flag supposed to only work with the most 
up-to-date octave and other packages on Octave Forge? Does that mean the other 
packages in the directory here 
(http://sourceforge.net/projects/octave/files/Octave%20Forge%20Packages/Individual%20Package%20Releases/)
 are just fallback for cases like mine that need/want to manually install older 
packages?

Sorry for my confusion. Thanks for any and all feedback, and best regards,

John
