Good morning I apologize for the fact that I
still need your help. I am not sure where I went wrong, however, below is the message
received in a terminal window. My daughter is actually the one who is
required to use Octave for a college assignment and the Mac Book Pro is hers.
Unfortunately, I do very well with my Windows PC but I find it difficult to maneuver
the same on an Apple. I hope there is a quick fix to this so that she can get
to work on her assignment. Thank you very much. Last login: Sun GNU Octave, version 3.4.0 Copyright (C) 2011 John W.

Thank you so much for your response.
Quick question. Prior to downloading and installing octave-3.4.0-i386.dmg that you
have suggested, should I completely eliminate the previous version 2011-04-21
binary of Octave 3.4.0 from her Mac? (that was previously installed and did not
function properly) It
actually looks to be the same binary. But yes, I would reinstall it making
sure to install gnuplot first. So put the octave.app in the trash,
re-mount the disc image and follow the steps outlined below. Note that if
you want to start octave from the command line (open
/Applications/Utilities/Terminal.app) you will have to add the path to the
octave binary as outlined below. Stu

Hello, My daughter installed Octave on her Mac Book Pro and it does
not seem to work. Each time she enters anything, it returns "syntax
error". I then installed Octave on my Windows PC and she was able to enter
same data and was able to plot it with no problem. Are there known issues associated
with Mac OS X? Downloaded versions and URL from which they were downloaded are
shown below. The version my daughter installed on her Mac Book Pro
appeared on the website http://sourceforge.net/projects/octave/files/Octave%20MacOSX%20Binary/ and
was the first link at the top of the webpage named 2011-04-21 binary of Octave
3.4.0 and does not seem to work. The version I installed on my Windows PC appeared on the
website http://sourceforge.net/projects/octave/files/Octave_Windows%20-%20MinGW/Octave%203.4.3%20for%20Windows%20MinGW%20Installer/ and
was the first link at the top of the webpage named
Octave3.4.3_gcc4.5.2-install.exe Please HELP. Thank you. This seems to be a common problem and has been discussed here on
several occasions in the past few months. I was preparing the following
for the 'wiki' but hadn't quite finished it. It should help you anyway. The following is current as of
20120105. The installation process has been confirmed on an iMac running
OS X 10.6.8 that has never previously had octave or gnuplot installed. Download this binary
(octave-3.4.0-i386.dmg) at: It's the latest version of octave
for which an OS X binary is available. Mount (double click) the dmg. Look in the 'Extras' folder and find
a gnuplot-4.4.3-aqua-i386.dmg disc image. This is a nice OS X binary of an up to
date version of gnuplot and, ironically, may be the only place such a gnuplot
binary exists for Open (double click) this dmg. Move the 'Gnuplot' icon to your
Applications folder. For purpose of this discussion - this is assumed to be
/Applications. If you are using a local Applications folder
(/~/Applications) appropriate modification of the paths specified below will be
necessary. At this point, Aquaterm is now also
installed. It is located at
/Applications/Gnuplot.app/Contents/Resources/lib/Aquaterm.app If you
need it for some other application, this is the path that will find it.
But don't move it to the upper level of the Applications folder - gnuplot
will be looking for it where it self-installs. (To inspect the contents
of an .app right click or control-click on it and select 'show package
contents') Move the 'Octave' icon from the
first .dmg to the same folder (/Applications). It is strongly suggested
that gnuplot be installed before octave. Now you have everything you need to
run octave/gnuplot/aquaterm. You can put the octave and gnuplot icons in
the dock and either will open in a terminal window with a simple 'click'.
To test octave, click its icon, and the octave prompt should appear in a
new terminal window along with some splash screen information. Then type
'sombrero(24)' at the octave prompt and after a while aquaterm will open and
the multicolor sombrero plot should appear. Starting octave from the command
line requires one further step to inform bash (your shell) where the octave
binary is located. This is accomplished through the bash initialization
file /.bashrc (. means it's normally invisible in the finder). The
simplest way is to add the PATH to the octave binary to your $PATH. Open a new terminal window.
Type (without the # comments): touch /.bashrc # this
creates a .bashrc file if one does not exist open /.bashrc # this opens .bashrc as a text document
(probably in TextEdit unless you have it set up for some other editor) In the document type: export
PATH=$PATH:/Applications/Octave/Contents/Resources/bin # this
appends the octave binary path to your existing path save and close .bashrc Either open a new terminal window,
or type 'source /.bashrc' in the existing one (to re-initialize it) and then
simply type 'octave' at the command line. Octave should start as
described above and you can repeat the 'sombrero' test to make sure everything
is working properly. Good luck Stu |
