These are notes on what you will need to do to install XPDP2.

First, if possible, enlist the aid of your system administrator
or your resident computer-wizard.

These are the software packages you will need:

Prerequisite graphics library tools:

tcl, tk, xpm
(these libraries are named
libtcl.a libtk.a libxpm.a)

tcl, tk, xpm are public domain graphics libraries which you
can obtain from many ftp sites.

For your convenience, we will place
tk3.6.tar.Z
xpm-3.4c.tar.gz
tcl7.4b1.tar.Z

up for anonymous ftp at langmuir.eecs.berkeley.edu in /pub.
We do not maintain these libraries, do not forward bug
reports about them to us, please.

If you do not already have these libraries, you must obtain them
and install them on your system.  Your system administrator will
help you do this, or you can simply obtain the libraries and
read the instructions on installing them.

The main code packages that you will get via this ftp are:

xgrafix.1.95.tar.gz  (or a later version)
pdp2.tar.gz	     (or a later version)

First you must uncompress these files with the gunzip or gzip -d
command.  Then you may run 

tar xf xgrafix.1.95.tar
tar xf pdp2.tar

This will make the following directories:

xgrafix.1.95 and pdp2

The first step is to configure xgrafix for your machine.
cd xgrafix
xmkmf
make

If you have installed tcl, tk, and xpm correctly, the compile
should go smoothly.  On some systems it may not:  some manual
editing of the Makefile might be necessary.  If your compiler
complains that certain include files or libraries can not be
found you may have to edit the makefile to add paths to these
files. Once the Xgrafix library is made you must install the
library and various other files on your system.  This must be
done by ROOT!!!!  Installation is achieved by typing 

make install

The Xgrafix library (libXGC20.a) need only be installed once
per file system.

When compiling XPDP2, root permision is not needed since it builds
its executable binary in the src directory.  To build it, simply type
make in the pdp2/src directory.  If your compiler complains that 
certain include files or libraries can not be found you may have to
edit the makefile to add paths to these files.
