Mooix is not exactly trivial to install. If possible, you should use one of
the precompiled packages instead of building mooix from scratch. This
document explains what you need to know to build mooix from scratch. 

First, you should check PORTING to see if your system is supported yet. If
not, read the rest of the info on porting it (and weep). If your system is
supported, read on..

Prerequisites
=============

	To build and use mooix, you need the Parse::RecDescent perl module
	(from CPAN), the the GNU readline library, and a recent version of
	perl (5.6 or above). You must have libperl as well; part of mooix
	links in the perl interpreter.

	If you want mooix to install language bindings for python or ruby,
	make sure you have those languages already installed before you
	build mooix. You'll need python 2.2.1 or later for the python
	language binding.

	Before you begin, you should also read the file ADDONS, which lists
	several software packages that will make mooix work better, but are
	not strictly required to use it.

Building
========

	BEFORE building mooix, first edit mooix.conf. Some values will be
	compiled into mooix, so read with care and change anything you
	need to.

	Then run ./configure, then make. (If you're really new at this, see
	the end of this file, where I have included the generic install
	instructions for programs using autoconf.)

        Mooix can embed the perl, python, and ruby interpreters for speed.
	To enable or disable embedded python and ruby, pass parameters
	like --with-embedded-pytohn, or --without-embedded-python, etc,
	to configure. Perl is alwayds embedded.

Installing
==========

	Note that mooix needs to be able to create device files in a
	directory underneath the libdir (/var/lib/mooix, or whatever).
	Putting that on a filesystem that is mounted nodev will not work.
	You can move and symlink the
	$libdir/mooix/system/sessionmanager/sessions directory to elsewhere
	if you run into this problem though.

	Before you run "make install", you should set up all the users and
	groups defined in mooix.conf; this is too system dependent to be
	done by an automated makefile. Then run "make install" to install
	everything.

	Depending on where mooix installed to, you may need to edit
	/etc/ld.so.conf to list the directory the mooix libraries were
	installed into, and run ldconfig.

Initialization
==============

	Next you need to get the moo daemon (mood) running. You can do this
	by just running 'mood' at the command line, if you like (as root).
	But you really should set it up to run when the system is booted,
	perhaps with an init script. An init script is a good idea, because
	it can take care of running the STARTHOOK and STOPHOOK commands in
	mooix.conf, to start the moo up cleanly, and shut it down cleanly.
	Until the STARTHOOK is run, the moo will refuse all logins. An init
	script for LSB systems is in lsb/init, and one for Debian is in
	debian/init.

Trying it out
=============

	With mood up and running, you can log into the moo for the first
	time -- read mooix(7).

Testing
=======
	
	If you want to, you can run "make fulltest" after installing mooix
	and starting the daemon, to run its main test suite. If the test
	suite fails, you should get on the mooix mailing list and report
	the problem. Note that the moo will not accept logins while testing
	is in progress.

Removing mooix
==============

	'make uninstall' will remove any files installed by 'make install',
	but you may need to clean up mooix users and groups, and perhaps
	other files created while mooix is running. Note that uninstall
	does delete your whole moo!

	Also, it may not currently remove all files installed as part of
	the perl binding. This is because perl's installation system does
	not support uninstallation, it seems.

-------------------------------------------------------------------------------

Well, that's all the help I can give you, except for these charming and
gripping generic installation instructions for programs that build using
autoconf:

   These are generic installation instructions.

   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, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').

   It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring.  (Caching is
disabled by default to prevent problems with accidental use of stale
cache files.)

   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 you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.

   The file `configure.ac' (or `configure.in') 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.

  2. Type `make' to compile the package.

  3. Optionally, type `make check' to run any self-tests that come with
     the package.

  4. Type `make install' to install the programs and any data files and
     documentation.

  5. You can remove the program binaries and object files from the
     source code directory by typing `make clean'.  To also remove the
     files that `configure' created (so you can compile the package for
     a different kind of computer), type `make distclean'.  There is
     also a `make maintainer-clean' target, but that is intended mainly
     for the package's developers.  If you use it, you may have to get
     all sorts of other programs in order to regenerate files that came
     with the distribution.

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

   Some systems require unusual options for compilation or linking that
the `configure' script does not know about.  Run `./configure --help'
for details on some of the pertinent environment variables.

   You can give `configure' initial values for variables by setting
them in the environment.  You can do that on the command line like this:

     ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix

   *Note Environment Variables::, for more details.

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 support 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.

   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.

   If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.

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' cannot 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 cannot guess the host type, give it the
`--build=TYPE' option.  TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:

     CPU-COMPANY-SYSTEM

where SYSTEM can have one of these forms:

     OS
     KERNEL-OS

   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 should
use the `--target=TYPE' option to select the type of system they will
produce code for.

   If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the host
platform (i.e., that on which the generated programs will eventually be
run) with `--host=TYPE'.  In this case, you should also specify the
build platform with `--build=TYPE', because, in this case, it may not
be possible to guess the build platform (it sometimes involves
compiling and running simple test programs, and this can't be done if
the compiler is a cross compiler).

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.

Environment Variables
=====================

   Variables not defined in a site shell script can be set in the
environment passed to configure.  However, some packages may run
configure again during the build, and the customized values of these
variables may be lost.  In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'.  For example:

     ./configure CC=/usr/local2/bin/gcc

will cause the specified gcc to be used as the C compiler (unless it is
overridden in the site shell script).

`configure' Invocation
======================

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

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

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

`--cache-file=FILE'
     Enable the cache: use and save the results of the tests in FILE,
     traditionally `config.cache'.  FILE defaults to `/dev/null' to
     disable caching.

`--config-cache'
`-C'
     Alias for `--cache-file=config.cache'.

`--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.

`configure' also accepts some other, not widely useful, options.  Run
`configure --help' for more details.
