I followed all the instructions on the page

http://www.octave.org/wiki/index.php?title=Installing_MacOS_X_Bundle

Specifically:

sudo touch /usr/local/bin/gnuplot

sudo ln -s /Applications/gnuplot.app/Contents/Resources/bin/gnuplot
/usr/local/bin/gnuplot

sudo touch /usr/local/bin/octave

sudo ln -s /Applications/Octave.app/Contents/Resources/bin/octave
/usr/local/bin/octave

But when I typed

octave

I got "permission denied".

Nevertheless, when I typed

env

I found that /usr/local/bin *is* in PATH

The next instructions said that I should then e-mail here.
Suggestions? Thanks.

Please verify you get the following.

ls -l /Applications/Octave.app/Contents/Resources/bin/octave
-rwxrwxrwx 1 bpabbott admin 2968 Apr 21 2011
/Applications/Octave.app/Contents/Resources/bin/octave

It's there, and so is gnuplot. They both show up, with the correct permissions. One small question, since my unix is rusty: octave shows -rwxrwxrwx and gnuplot shows -rwxrwxrwx@ -- what's the difference?

And I don't understand: if it's -rwxrwxrwx, how can there be "permission denied"?

Ok. Now try to run Octave without the link. Just type the part below at the shell prompt.

/Applications/Octave.app/Contents/Resources/bin/octave

OK, that works.

Ok. Now fix the links. First, delete the old ones.

sudo rm /usr/local/bin/gnuplot
sudo rm /usr/local/bin/octave

... and then recreate them.

sudo touch /usr/local/bin/gnuplot

sudo ln -s /Applications/gnuplot.app/Contents/Resources/bin/gnuplot /usr/local/bin/gnuplot

sudo touch /usr/local/bin/octave

sudo ln -s /Applications/Octave.app/Contents/Resources/bin/octave /usr/local/bin/octave

Ben

I notice that ls -l /usr/local/bin/octave gives -rw-r--r-- Evidently that's where the execute permission is denied. But why is it that way? Can I merely do a chmod?

ok. Try ...

chmod 755 /usr/local/bin/octave
chmod 755 /usr/local/bin/gnuplot

Ben

I've added this part to the wiki. Please confirm this works for you.

Nope. I got

"chmod: Unable to change file mode on /usr/local/bin/octave: Operation not permitted"

"Unable to change file mode on /usr/local/bin/gnuplot: Operation not permitted"

Hmmm.

Try navigating the Finder to /usr/local/bin (you can use [Go -> Go to Folder] and then type in the path.

Once there do a "Get Info" on "/usr/local/bin/octave" and verify the original is what it should be.

"Get Info" on the one (or ones -- octave and gnuplot) in /usr/local/bin/ doesn't show any reference at all to the one in Applications (which I assume is what you mean by "the original").

BTW, while I'd like to get the in-terminal invocation straightened out, I meanwhile started successfully calling octave.app from OS X, which opens the terminal and then successfully starts octave.
