Re: octave & octave-forge install instructions for Mac OS X 10.4.x

[Henry F. Mollet]

First going a step back.
Where do I put "set term aqua" for gnuplot and "gset term aqua" for octave?
That's what I'm using presently in the Terminal so I can use plot etc.
I have checked on my old fink installation for octave 2.1.46 and gnuplot
3.8i:
1. .gnuplot is empty
2. .octaverc has LOADPATH, but nothing about aqua
3. .cshrc has commented out #setenv GNUTERM aqua
Therefore I have no clue how gnuplot finds Aquaterm when it is called by
octave. Don't know how octave finds gnuplot either.

As I'm now using the bash shell, does

GNUTERM=aqua or is it
export GNUTERM="aqua"

have to be added to my .profile?
henry-f-mollets-emac:~ hfm$ cat .profile
export PATH="$PATH:/Developer/Tools:/usr/local/bin"

For X11 is 
DISPLAY=:0.0
That has to be added to my .profile also?

Sorry, I'm having a hard time with X11. I just don't know what exactly it
is. I can open it but don't know the difference of running octave in the
terminal compared to running it in X11. Is there an easy explanation/analogy
that I can understand?

According to what you said and my notes, X11 is required for xpm (was
eliminated from the list of packages because no X 10.4 version exists yet),
qhull (geometry toolbox). X11 is options for octave but AquaTerm appears to
be easier to use. Not sure if X11 is an option for octave-forge or if it is
needed at least for a few items.

Since X11 was installed at the very end, I guess that I now have to tell
each application above where it is?

Or take qhull: If I re-install with X11 present then it should work?
