This file is INSTALL. It contains installation instructions for Expect.
If you are installing on a single architecture, or are just trying
Expect out to see whether it's worth installing, follow the Simple
Installation below. If you are installing Expect on multiple
architectures or the "Simple Installation" instructions are not
sufficient, see "Sophisticated Installations" below.
--------------------
Simple Installation
--------------------
Run "./configure". This will generate a Makefile (from a prototype
called "Makefile.in") appropriate to your system.
Edit the Makefile and change any definitions as appropriate for your
site. All the definitions you are likely to want to change are
clearly identified and described at the beginning of the file.
Run "make expect".
This will build a stand-alone Expect program which you can then
experiment with.
To build everything, run "make".
This will build "expectk" (Expect with Tk) as well as libraries for
embedding Expect with Tcl (libexptcl.a) and Tk (libexptk.a) in your
own programs.
"make install" will install Expect and optionally Expectk and the
libraries if you have built them.
A handful of people running "pure" 4.2BSD systems have noted that
expect fails to link due to lack of getopt and vprintf. You can get
these from uunet or any good archive site.
--------------------
Expect scripts included in the "example" directory
--------------------
kibitz - lets two people control a program at the same time.
Lots of uses. I.e., You can help another person remotely.
Can run an editor and log a transcript of a conversation.
See man page or SP&E paper.
rogue.exp - finds a good game of rogue.
chess.exp - has two chess games play each other.
autopasswd - runs passwd non-interactively (you must be root).
passmass - sets passwd on many machines simultaneously.
timed-read - a timed read for the shell
lpunlock - unhangs a printer which says it is "waiting for lock".
dvorak - dvorak keyboard
weather - retrieves weather forecasts.
timed-run - run a program for only a given amount of time.
rftp - recursive ftp (assumes UNIX-style ftpd at other end).
archie - mails back response after talking to archie ftp-catalog.
gethostbyaddr - translates internet address to name (with a higher
success rate than nslookup). Easier to use, too.
ftp-rfc - retrieve a DoD RFC from uunet via anonymous ftp
robohunt - plays the game of hunt (from Berkeley)
It's more of a wild player than good, but amusing to watch.
Fun to throw against people who don't know about it.
rlogin-cwd - rlogin giving you same current working directory
To run, for example, chess.exp, type:
expect chess.exp
If expect is installed and your system supports the #! magic you can
invoke it as just:
chess.exp
Each of these examples necessarily depends upon other binaries in the
system. For example, chess.exp depends upon the "usual" UNIX chess
program being present. If any of these programs are different,
it may cause the associated script to misbehave.
Please use the ".exp" extension on scripts that might otherwise have
names that could be confused with the real program, such as "rogue.exp".
Scripts that have unique names do not need the extension, such as "rftp".
--------------------
Sample Expectk scripts included in the example directory
--------------------
xpstat - provide an X window front end to the xpilot game.
--------------------
Sample C and C++ programs that use libexpect.a included in the example
directory
--------------------
chesslib.c - same thing as chess.exp, but in C.
chesslib2.c - ditto, but uses popen and stream-style I/O.
chesslib++.c - ditto, but for C++.
You may change the value of CC or CPLUSPLUS in the Makefile, to
compile under gcc or other compilers. However, you may have to edit
the lines defining where the libraries are.
--------------------
Sophisticated Installations
--------------------
The following instructions provide some suggestions for handling
complex installations.
--------------------
Multiple-Architecture Installation
--------------------
You might want to compile a software package in a different directory
from the one that contains the source code. Doing this allows you to
compile the package for several architectures simultaneously from the
same copy of the source code and keep multiple sets of object files on
disk.
To compile the package in a different directory from the one
containing the source code, you must use a version of make that
supports the VPATH variable. GNU make and most other recent make
programs can do this.
cd to the directory where you want the object files and executables to
go and run configure. configure automatically checks for the source
code in the directory that configure is in and in .. If configure
reports that it cannot find the source code, run configure with the
option --srcdir=dir, where dir is the directory that contains the
source code.
--------------------
Changing Defaults
--------------------
Some of the defaults in "configure" can be overridden by environment
variables. This is a convenience intended for environments that
likely affect any program that you configure and install.
The following variables are supported:
CC C compiler program.
Default is `cc', or `gcc' if `gcc' is in your PATH.
INSTALL Program to use to install files.
Default is `install' if you have it, `cp' otherwise.
These settings can also be given on the command line. For example,
you could tell configure about a particularly C compiler from a
Bourne-compatible shell as follows:
CC='gcc -traditional' DEFS=-D_POSIX_SOURCE
