The GNUPLOT source code and executables may be copied and/or modified
freely as long as the copyright messages are left intact.

See the History file for changes to GNUPLOT.

Compilation instructions are near the end of this file.

GNUPLOT has been tested on Sun3's and Sun4's (SunOS 4.0.3 and 4.1.1),
a VAX 6410 (VMS 5.2), Commodore Amiga's (KS/WB 1.3 and 2.0, Lattice C
and Aztec C beta 5.2a), IBM PC XT's and AT's (MS-DOS 3.3/5.0 BC++ 2.0/TC++
1.0), IRIS 4D/70G and 4D/25G with MIPS C, NeXT with gnu C 1.34,
DECStation 5000/200PXG (ULTRIX V4.1),
AT&T 3B1 (version 3.51m with cc and gcc 1.39),
and Apollo's (DomainOS SR10.3 BSD4.3 with C compiler 68K Rev 6.7(316)).
The code is written with portability in mind.
GNUPLOT has not been tested on Pyramid 90x and IBM PC Microsoft C.

These #defines are defined automatically by various compilers, some
gnuplot routines check these defines to implement features found in the
various environments:

define 	      note
------        --------
AMIGA_AC_5    defined for Manx Aztec C 5.2a on the Amiga
AMIGA_LC_5_1  defined for Lattice C 5.01 on the Amiga
apollo        defined by Apollo's C compilers.
_CRAY         defined by CRAY's C compiler.
__TURBOC__    defined automatically by Turbo C 2.0, C++ 1.0, Borland C++ 2.0
unix          defined by most unix C compilers.  
vms           (and VMS) defined by VAX-11 C under VMS.
__ZTC__       Zortech C compiler under MSDOS.


                             TO COMPILE

under UNIX:  
To compile do:
  Copy makefile.unx to Makefile
      cp makefile.unx Makefile
  Look through the Makefile to see if you need to make any changes.
  See especially the HELPDEST and TERMFLAGS variables.  Edit if needed.
  Alternatively, all these variables may be set as command line arguments to
  'make'. For example:

	make <MACHINE> HELPDEST='/usr/um/misc/lib/gnuplot.gih' \
		DEST='/usr/um/misc/bin' READLINE=

  Edit term.h, to include/exclude terminals
  Type
      make
  For further instructions.
  If that works, try
      make install
  For further instructions.

under VMS:  
  To compile:
     copy makefile.vms makefile.
     make
  Or if you don't have a suitable make:
     @buildvms
  To tell gnuplot where to find the help library:
      $ define gnuplot$help disk:[directory]gnuplot.hlb
  Alternatively (and preferably) put the help in the main system help library.

under AmigaDOS:
Using Aztec C 5.2a
      make -f makefile.ami
Using Lattice C 5.1
      lmk -f makefile.amg

under MSDOS:
Using Microsoft C 5.10.
      copy makefile.msc makefile
      make makefile

Using Borland C++ 2.0, Turbo C++ 1.0
      copy makefile.tc makefile
  Edit makefile to change TC, BIN, BGI, BGIOBJ. You may also want to turn
      on overlays (See manual for more on overlays).
  Edit linkopt.tc (linkopt.tco if overlays on) to change location of
      libraries.
      make

Using Turbo C 2.0.
  As per Borland C++ 2.0. Edit linkopt.tc to change location of libraries.


The file gnuplot.gih is needed for help on the PC.
If the file gnuplot.gih is not in the default directory, then use:
    set GNUHELP={full path name of gnuplot.gih}


                         ENVIRONMENT VARIABLES

See 'help environment'.

If the environment variable GNUTERM is found, it is used as the terminal
type. Otherwise, in some cases the variable TERM will be used, or the
hardware may be automatically detected. 

The PC version looks for the environment variable GNUPLOT to contain
the name of the directory from which to load the initialization file
GNUPLOT.INI.  See the help on 'start_up' for more information.

HOME is examined as a directory where a .gnuplot startup file might be
found. See help on "start-up".

If defined, the environment variable GNUHELP is used for the name
of the .gih help file, otherwise HELPFILE (defined in makefile or 
plot.c) is used.

The VMS version looks for the logical name GNUPLOT$HELP to locate 
the help library.

The CGI drivers need the CGIPATH environment variable to set the path
to the CGI agents, and the CGIDISP and/or CGIPRNT environment
variables to set the output devices.
