Getting gnuplot
Download gnuplot, version 3.8i.0
(this is the latest MacOSX compatible version at the time of the writing of this file).
Installing gnuplot
Open the Terminal, and become superuser by typing in su and typing-in
your root password when asked to do so. Then cd to the folder where
you downloaded gnuplot (for example /Users/goofy/downloads):
cd /Users/goofy/downloads
Unpack the archive:
tar -zxvf gnuplot-3.8i.0.tar.gz
Go into the newly created directory:
cd gnuplot-3.8i.0
Configure gnuplot (don't break the line):
./configure --prefix=/sw --without-gd --mandir='${prefix}/share/man'
--with-readline=gnu --enable-mouse --enable-pm3d --with-png --with-pdf --enable-filledboxes
--enable-relative-boxwidth --enable-thin-splines
If you don't have libpng installed, remove the command
--with-png. If you don't have teTeX installed or any Terminal-based
TeX/LaTeX installation, remove the command
--with-pdf.
When it's done, compile:
make
When it's done, install gnuplot:
make install
When it's done, resign from superuser:
exit
Now you should have a working installation of gnuplot in
/sw/bin/gnuplot.
