COMPILATION of ARIBAS (V. 1.53, Nov. 2004)

To compile ARIBAS on a UNIX workstation, the following 25 files are 
necessary.

a) 23 C-Files

alloc.c     analysis.c  aritaux.c   arith.c     aritool0.c  aritools.c
aritx.c     arity.c     aritz.c     array.c     control.c   errtext.c
eval.c      file.c      mainloop.c  mem0.c      parser.c    print.c
scanner.c   storage.c   syntchk.c   sysdep.c    terminal.c

b) 2 Include-Files

logscr.inc 	(included by terminal.c)
common.h	(common header file)

The c-files must be compiled with the symbol UNiX defined (note the
lower case i), so when all the above files (and no other c-files) 
are in the current directory, the simple command line

	cc -DUNiX -o aribas *.c

will compile aribas (please note the lower case i in UNiX). 
But you may also use the provided Makefile and compile
aribas with the command

	make

If you have problems with system dependent functions (they are
concentrated in the file sysdep.c), you may either edit the file
sysdep.c according to the needs of your system or try 

	cc -DUNiX -DSysDUM -o aribas *.c

This will substitute dummy functions; the ARIBAS function timer and
the automatic initialization of the random generator will not work,
but everything else will not be affected.

LINUX VERSION

In the LINUX version for Computers with Intel 80386 processor (or higher),
some C functions of the file aritool0.c are substituted by
functions written in Assembler. The subdirectory LINUX contains the 
necessary file arito386.S and a makefile with name Makefile.linux.

INSTALLATION

To run ARIBAS, only the executable file aribas is necessary.
Move it to a directory which is in the PATH variable. If
you want online help, you need also the file aribas.hlp, which
must be placed in a directory which is in the PATH variable.
There is also an interface to run ARIBAS within the GNU Emacs
editor (version 19.xx or higher). The necessary Emacs Lisp file is
aribas.el in the sub directory EL. Please read the corresponding
README file.
