Basic Installation
==================

   The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation.  It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions.  Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, a file
`config.cache' that saves the results of its tests to speed up
reconfiguring, and a file `config.log' containing compiler output
(useful mainly for debugging `configure').

This package requires the following:

1. XFree86 installed (it was developed with 3.3.2)

2. WindowMaker >= 0.70.0 (for WINGs and wraster libraries and header files).
   There are no other dependencies on WindowMaker and wdm can run
   any other window manager such as AfterStep, icewm, BlackBox, etc.

3. autoconf => 2.53 for maintenance (any building)...
   (automake is not used any more)

4. libXft or libXft2 is required if you have compiled WINGs with Xft 
   support.
   

NOTE: The wdm tarball currently contains the xdm sources. They keeped for
   referential purposes only. It would be easier to update xdm base of
   wdm to newer xdm versions.

   If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release.  If at some point `config.cache'
contains results you don't want to keep, you may remove or edit it.

   The file `configure.ac' is used to create `configure' by a program
called `autoconf'.  You only need `configure.ac' if you want to change
it or regenerate `configure' using a newer version of `autoconf'.

The simplest way to compile this package is:

  1. `cd' to the directory containing the package's source code and type
     `./configure' to configure the package for your system.  If you're
     using `csh' on an old version of System V, you might need to type
     `sh ./configure' instead to prevent `csh' from trying to execute
     `configure' itself.

     Running `configure' takes awhile.	While running, it prints some
     messages telling which features it is checking for.

     ./configure --help can be used to see what options are
     available.

     configure script will try to detect library to use for authentication.
     First it checks for pam. If pam library was not found than it checks for
     shadow. If shadow is not supported it falls back to looking in /etc/passwd.
     Any check can be disabled with --disable-pam or --diable-shadow option.
     Specifying --enable-pam or --enable-shadow will check only for requested
     library.
     
  2. Type `make' to compile the package.  A number of the configure options
     can be overriden (or just plain specified) on the make command line.

*****Examine (and optionally modify) the configuration files in
     ./configs directory

  3. Type `make install' to install the programs and any data files and
     documentation.  To install into a path other than that specified by
     ./configure --prefix=<...> (such as testing the install), you can
     use make DESTDIR=<...> install.  For exmaple:

     make DESTDIR=/tmp/wdm-root install

     will install the binaries into /tmp/wdm-root/usr/local/bin.

  4. You can remove all files created by make command in source code
     directory by typing `make clean'. To also remove the files created 
     by `configure' script type `make distclean'.

  5. Modify system initialization (/etc/inittab on RedHat Linux) to
     invoke wdm at system startup or start wdm (as root) with
     the following command line:

     wdm -nodaemon

     or

     wdm -nodaemon -config /usr/local/etc/wdm/wdm-config

     Please note:  if you start wdm "detached", you will be unable
     to actually terminate the wdm process.

     for Debian GNU/Linux systems, what I find easier is to modify
     /etc/init.d/xdm to launch wdm instead of xdm (if you don't need both)

     for RedHat based Linux systems, modify /etc/inittab the following way:
     ensure this file contains the following lines (don't duplicate existing
     lines beginning with 'id' or 'x', modify them in place):

     id:5:initdefault:
     x:5:respawn:/usr/local/bin/wdm -nodaemon

     for other systems, I don't know.

     By default, wdm installs into /usr/local/bin, /usr/local/man,
     /usr/local/etc/wdm (configuration files), and (if pam is enabled),
     /etc/pam.d

*****************************************

ATTENTION: According to Bevan Broun (bevanb@ee.uwa.edu.au) there's a problem
compiling wdm under Irix 6.5.2 because setpgrp needs no argument under Irix.
It's a problem in xdm's code, not wdm's code, so no patch was made by me (Jerome)
but the temporary solution is to modify the lines where setpgrp is called and
it works fine. A better solution would be to put some new autoconf/automake
test but I don't know how to do. If you're an autoconf guru don't hesitate to
help me :-)

***NOTE***********************************************************NOTE****

Please examine (and modify if necessary) the Xsession* and Xclients* files
in the wdm config directory (by default: /usr/local/etc/wdm).  Also,
note that this files MUST be marked executable.	 These files are the
shell files which actually create the user's environment and start
the window manager.  The can also have a ~/.xsession or a ~/.Xclients file
in which case these files are executed (and MUST be marked executable).

In addition, review the other other files (especially wdm-config)
in the wdm config directory and change them as necessary for your
system.	 For example, if installing on a non Linux system such as
FreeBSD, you will need to change the parameters for the shutdown
commands.

You may also need to edit Xsession and Xclients to change how
the shell program is called and its parameters.

Xsession and Xclients are separate so that a user can create their own
version of Xclients and put it in their home directory as ~/.Xclients

./configure attempts to properly configure the files in wdm's config
directory but differences between systems can result in the need to
manually tailor these files for your system.  Please examine these
files before trying wdm.

**************************************************************************

Authentication options
======================

wdm supports three options:

   1. use pam if found and no --disable-pam option was specified in
      command line.

   2. use shadow if check for pam failed and no --disable-shadow
      option was specified at command line.

   3. use passwords from /etc/passwd.


Window Manager Options
======================

./configure and Xclients include startup code for a number of window managers.
This includes the programs named wmaker, afterstep, blackbox, icewm, xsession,
and kde (really startkde).  ./configure trys to locate these programs but
if not found Xclients will have their respective startup code commented out.

There are also two options for specifying an arbitrary window manager:
--with-winmgr=NAME and --with-winmgr_path=PATH.	 If specified, this name
will be added to the list of available window managers.

If --with-wmlist=<...> is used to specify a list of window manager program
names (colon separated), then be sure to check/modify Xsession and Xclients
so that the window managers start properly.

Graphics options
================

   wdm uses the WINGs and wraster libraries.  Therefore, ./configure
   should be run with the same graphic options you used to install
   WindowMaker.

   --with-Logo=<...> can be used to specify a Logo pixmap.

NOTE
====

1. The Xsession and Xclients distributed scripts are configured for
running on RedHat Linux 5.1.  If this is what you are running, it should
work.  Otherwise, they may need some modification.

2. The primary configuration file is wdm/wdm-config.  This is an
Xresource file.	 The new (added) options are:

DisplayManager*wdmLogin:	<locate of the Login program>
DisplayManager*wdmBg:		<background specification>
DisplayManager*wdmLogo:		<path of Logo pixmap>
DisplayManager*wdmWm:		<list of window managers separated by colons>
DisplayManager*wdmReboot:	<command to execute to reboot>
DisplayManager*wdmHalt:		<command to execute to halt>
DisplayManager*wdmVerify:	<true/false> -- Verify user for reboot/halt/exit
DisplayManager*wdmRoot:		<true/false> -- user must be verified root to exit
DisplayManager*wdmLoginConfig:	<path to configuration file for wdmLogin>
DisplayManager*wdmHelpFile:	<path to file displayed in help window>
DisplayManager*wdmAnimations:	<true/false> -- Enable animations for events.
DisplayManager*wdmLocale:	<locale to use with wdmLogin>
DisplayManager*wdmCursorTheme:  <XFree86 4.3.x cursor theme to use>
DisplayManager*wdmXineramaHead: <display on which login panel will appear>

background specifications:
	pixmap:full_path_to_background_pixmap
	solid:<a color>
	hgradient:<list of colors separated by commas>
	vgradient:<list of colors separated by commas>
	dgradient:<list of colors separated by commas>
		h=horizontal, v=vertical, d=diagonal
		multi-gradients.

3. wdmLogin program uses separate configuration file in proplist format.
Filename is defined with wdmLoginConfig resource in wdm-config file.
Here's example of that file with all options filled with default values.

{
	geometry = (530, 240);
	aa = no;
	multibyte = no;
}

"aa" and "multibyte" options available if wdm was compiled with --enable-aafont option.
"geometry" option can also have two addittional integers, that will specify screen 
position of login panel.  Like:
geometry = (530, 240, 50, 100);


Compilers and Options
=====================

   Some systems require unusual options for compilation or linking that
the `configure' script does not know about.  You can give `configure'
initial values for variables by setting them in the environment.  Using
a Bourne-compatible shell, you can do that on the command line like
this:
     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure

Or on systems that have the `env' program, you can do it like this:
     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure

Compiling For Multiple Architectures
====================================

   You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory.	To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'.  `cd' to the
directory where you want the object files and executables to go and run
the `configure' script.	 `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.

   If you have to use a `make' that does not supports the `VPATH'
variable, you have to compile the package for one architecture at a time
in the source code directory.  After you have installed the package for
one architecture, use `make distclean' before reconfiguring for another
architecture.

Installation Names
==================

   By default, `make install' will install the package's files in
`/usr/local/bin', `/usr/local/man', etc.  You can specify an
installation prefix other than `/usr/local' by giving `configure' the
option `--prefix=PATH'.

   You can specify separate installation prefixes for
architecture-specific files and architecture-independent files.	 If you
give `configure' the option `--exec-prefix=PATH', the package will use
PATH as the prefix for installing programs and libraries.
Documentation and other data files will still use the regular prefix.

   There is a separate option to specify the location of wdm's
configuration directory: --with-wdmdir=<...>.  For example, if you
use --prefix=/usr/X11R6 but you want the configuration directory in
/etc/X11, use --with-wdm-dir=/etc/X11.

   There is also a special option for the pam directory --with-pamdir=.
Be default, the pam configuration file is installed in /etc/pam.d if
--enable-pam is specified.  Use --with-pamdir=<...> to put it somewhere else.

   In addition, if you use an unusual directory layout you can give
options like `--bindir=PATH' to specify different values for particular
kinds of files.	 Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.

Optional Features
=================

   Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System).  The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.

   For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.

Specifying the System Type
==========================

   There may be some features `configure' can not figure out
automatically, but needs to determine by the type of host the package
will run on.  Usually `configure' can figure that out, but if it prints
a message saying it can not guess the host type, give it the
`--host=TYPE' option.  TYPE can either be a short name for the system
type, such as `sun4', or a canonical name with three fields:
     CPU-COMPANY-SYSTEM

See the file `config.sub' for the possible values of each field.  If
`config.sub' isn't included in this package, then this package doesn't
need to know the host type.

   If you are building compiler tools for cross-compiling, you can also
use the `--target=TYPE' option to select the type of system they will
produce code for and the `--build=TYPE' option to select the type of
system on which you are compiling the package.

Sharing Defaults
================

   If you want to set default values for `configure' scripts to share,
you can create a site shell script called `config.site' that gives
default values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists.	Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.

Operation Controls
==================

   `configure' recognizes the following options to control how it
operates.

`--cache-file=FILE'
     Use and save the results of the tests in FILE instead of
     `./config.cache'.	Set FILE to `/dev/null' to disable caching, for
     debugging `configure'.

`--help'
     Print a summary of the options to `configure', and exit.

`--quiet'
`--silent'
`-q'
     Do not print messages saying which checks are being made.	To
     suppress all normal output, redirect it to `/dev/null' (any error
     messages will still be shown).

`--srcdir=DIR'
     Look for the package's source code in directory DIR.  Usually
     `configure' can determine that directory automatically.

`--version'
     Print the version of Autoconf used to generate the `configure'
     script, and exit.

`configure' also accepts some other, not widely useful, options.
