Plotting with Octave after most recent MAC OSX update

Question

Hi I just recently downloaded the most recent snow leopard update. Then I tried to plot something using Octave which has been installed on my computer for months (and plotting has worked all that time) Even since I installed the update, and I try to plot using octave I get the following error:

dyld: Library not loaded: /usr/X11/lib/libfreetype.6.dylib

  Reason: Incompatible library version: libfontconfig.1.dylib requires version 13.0.0 or later, but libfreetype.6.dylib provides version 10.0.0

error: you must have gnuplot installed to display graphics; if you have gnuplot installed in a non-standard location, see the 'gnuplot_binary' function

I'm really not sure what to do. I'm way out of my league here.

Answer 1

The "note for MacOSX users" is no longer on the Octave homepage, and the workaround described in Marco's post didn't work for me either, but this did:

Open /Applications/Gnuplot.app/Contents/Resources/bin/gnuplot in a text
editor. Use the editor search-and-replace feature to replace
"DYLD_LIBRARY_PATH" with "DYLD_FALLBACK_LIBRARY_PATH". There are four
instances that need to be replaced.

This is from the readme for the Octave MacOSX Binary. Note that it says it's for Lion users, but I'm running 10.6.8 and it worked for me.

Answer 2

I've recently build Octave and GNUplot on Lion using homebrew. Seems to work well. Here are some notes

1. Install Xcode from AppStore and HomeBrew (see Link)

2. Run 'brew install octave" and wait until graphicsmagick fails to compile

3. Run the command "brew install --use-clang --HEAD graphicsmagick". You might be asked to install Mercurial, just follow the instructions. You may also be asked to install fortran, so "brew install gfortran"

4. Run the command "brew install octave" again

5. Install Aquaterm

6. Now run "brew install gnuplot"

You now have the latest Octave installed. Just type octave from the terminal

To test the install run the following commands at the Octave command prompt

setenv("GNUTERM", "x11");
x = linspace(-10, 10, 100);
y = sin(x);
plot(x,y);
