I've spent the last couple of days trying to get Octave installed to
run some code for an assignment for uni in computer vision.
OS: Mac OS X 10.5 on a PowerBook G4
My steps have been:
1) downloaded and installed Octave.app (3.0.0) from
http://octave.sourceforge.net/
2) installed gnuplot and AquaTerm, mucked around until those seemed
to
be working:
octave-3.0.0:1> plot([1 2 3],[1 2 3], 'kx')
comes up with a figure showing what you'd expect.
3) loaded up my code and got the following error:
error: `imread' undefined near line 20 column 13
error: evaluating assignment expression near line 20, column 11
error: near line 20 of file `Assignment1.m'
4) assumed that the functionality of imread doesn't come standard
with
Octave.app
5) downloaded the octave-forge-bundle-20080216
6) tried to install
pkg install image-1.0.5.tar.gz
which took a while and gave errors I didn't copy down, but appeared
to
me to have something to do with ld not finding symbols.
7) from random googling et cetera, assumed my problem was that I
don't
have something called "imagemagick"
8) downloaded, compiled, installed, updated fink
9) used FinkCommander to install imagemagick 6.3.8, which took hours
and installed a whole lot of stuff. I think the complete list is 266
items long. It seems to be installed and working, because:
address@hidden ~]$ convert --version
Version: ImageMagick 6.3.8 04/10/08 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2008 ImageMagick Studio LLC
[snip]
So now I'm stumped and out of ideas. Am I on the right path? How do
I get Octave to see that I have imagemagick installed?
Any help will be sincerely appreciated,
Nic Jones
I have Octave & imagemagick installed via Fink. Installing the image
package resulted in the following
octave:3> pkg install image-1.0.5.tar

While all of that looks ominous, when I tried to read a jpg, it
appears to do so without problem.
octave:10> img = imread('MacGuy.jpg');

I'm running OSX 10.5.2 on Intel. My Octave source files are locally
installed (i.e. not directly from Fink, but built and installed using
Fink).

There appear to be three differences between your situation and mine.
(1) you did not use Fink to install Octave. (2) You are using a source
distribution that is a few months older than mine, and (3) you Mac is
a G4 and mine an Intel.
I don't have the time to try this out on my G4, but will give it a try
tomorrow. In the meantime, you might want to try to uninstall Octave
and reinstall via Fink (that approach will also take care of many
dependencies).
