To install from sources:

========================

Installation instructions are found in the file INSTALL in this

directory after going through this file. In a very small nutshell:

- Under Unix, use configure and make

If your source is from the CVS repository rather from a release package,

the order of commands is ./prepare; ./configure; make

- Other platforms, copy the relevant makefile from config/

to src, cd to src and make. See config/README for what each

of those files is for. Note: some of those files haven't been

updated in ages, so they may no longer be usable.

IMPORTANT NOTE ON PDF SUPPORT

===========================================

Direct PDF support in gnuplot is provided by an external library.

Two options are currently possible. It is possible to have both

PDF terminal drivers in the same gnuplot executable.

The newer "pdfcairo" terminal uses the pango and cairo libraries.

This driver will be built if the configure script detects suitable

versions of cairo and pango on your machine.

The older "pdf" terminal uses a library provided by PDFlib GmbH,

Germany ( http://www.pdflib.de/ ). This library is available under

two strictly separate licencing models. Depending on the environment

you use gnuplot in, you may have to purchase a commercial licence for

PDFlib even though gnuplot itself is free software.

There's a special version of PDFlib, called ``PDFlib Lite'', which

is freely redistrutable, but programs linked to that are strictly for

non-commercial usage only. *You* are liable for whatever violations

of this licence occur in a gnuplot binary built by you.
