< device > denotes the standard rewind device entry for the
device you wish to read from. Device entries usually
have names like /dev/tape, dev/rmt0,...
If you are unsure about the correct device entry to use,
consult your system manuals or ask a colleague responsible
for the system maintenance of the machine you are using.
The IF/Prolog files are written on the tape in standard
Unix tar format. Each tarfile contains a number
of files which are transferred to a subdirectory on your
machine while the tarfile is read.
The IF/Prolog delivery tape contains one file (tarfile) for the
IF/Prolog development system, one file for every additional
interface available (e.g. OSF/Motif interface, Informix Interface, Constraints)
plus one file containing the installation scripts.
You first read the tarfile containing the installation scripts
from the tape.
a.
Read the contents of the distribution tape.
b.
Read all tarfiles on the remote machine.
c.
Transfer the tarfiles to the machine where you want to install.
You can use rcp (remote copy), ftp in binary mode or any
other appropriate tool.
Change the current directory ( cd ) to this directory.
The installation procedure will ask you a few questions as
to where to install IF/Prolog and how to configure the
IF/Prolog kernel.
You may install any interface you like and
have disk space for, but you can only use those interfaces
of IF/Prolog for which you have purchased a license.
The IF/Prolog kernel automatically generated during
installation will include all installed interfaces.
You have to execute the script link_prolog
if you want to bind
a smaller kernel that excludes those interfaces for
which you have no license.
If you are installing from tape,
the installation script will suggest an installation directory.
If you execute the ./install script as the superuser,
this default directory is system dependent.
Otherwise, the default directory is the subdirectory prolog
in the home directory of the person installing.
However, you can install IF/Prolog in any directory you have write
access to.
IF/Prolog will be generated according to the options
you chose. You can always generate alternative or
additional IF/Prolog kernels
with different options at a later time by executing the
link_prolog script delivered with the IF/Prolog system.
IF/Prolog uses the PROROOT environment variable to
dynamically load additional data when needed. The way
to set an environment variable depends on the command
shell you use. Below we list the commands for the more
common shells.
Korn shell, Bourne shell, or a related shell
Bourne shell (sh): set PROROOT=< directory >
export PROROOT
Korn shell (ksh): typeset -x PROROOT= < directory >
You should add those commands to the file .profile
in your home directory. Then those commands
will be executed automatically every time you login.
Setting the PROROOT environment variable is not necessary
when you install IF/Prolog as a superuser and select the
system dependent installation directory proposed by the
installation script.
You can always call IF/Prolog with the command
$PROROOT/bin/prolog
or with the full directory path name.
To call it just by prolog,
you must add the subdirectory $PROROOT/bin
to the PATH environment variable.
Look in your .profile file for a line
PATH= < some directories >
and edit it to include the IF/Prolog installation path:
PATH=...:$PROROOT/bin:...
If you cannot find this line, add the lines
PATH=:$PATH:$PROROOT/bin
export PATH
C shell or a related shell
setenv PROROOT < directory >
You should add this command to the file .login
in your home directory. Then this command
will be executed automatically every time you login.
Setting the PROROOT environment variable is not necessary
when you install IF/Prolog as a superuser and select the
system dependent installation directory proposed by the
installation script.
You can always call IF/Prolog with the command
$PROROOT/bin/prolog
or with the full directory path name.
To call it just by prolog ,
you must add the subdirectory $PROROOT/bin
to the path or PATH environment variable.
Look in your .login file for a line
set path = ( < some directories > )
and edit it to include the IF/Prolog installation path:
set path = ( ... $PROROOT/bin ...)
If you cannot find this line, add the line
set path = ( $PROROOT/bin $path )
