             How to install Ncurses/Terminfo on your system 
---------------------------------------------------------------------
    ************************************************************
    * READ ALL OF THIS FILE BEFORE YOU TRY TO INSTALL NCURSES. *
    ************************************************************

You should be reading the file INSTALL in a directory called
ncurses-d.d.d, where d.d.d is the current version number.  There
should be several subdirectories, including `c++', `form', `man', `menu',
'misc', `ncurses', `panel', `progs', and `test'.  See the README file
for a roadmap to the package.

If you are a Linux or FreeBSD or NetBSD distribution integrator or packager,
please read and act on the note addressed to you below.

REQUIREMENTS:

You will need the following in order to build and install ncurses under UNIX:

	* ANSI C compiler  (gcc is recommended)
	* sh               (bash will do)
	* awk              (mawk or gawk will do)
	* sed
	* BSD or System V style install (a script is enclosed)

INSTALLATION PROCEDURE:

1.  IF YOU HAVE ROOT: First, decide where you want to put the object files of
    terminal descriptions. (If you don't have root, you may skip this step.)
    The default is /usr/lib/terminfo.  If your system already has a
    terminfo database, you can put it somewhere else.  Keep in mind that 
    this directory should probably be in your root filesystem so that 
    programs which use terminfo can be used even when the system is only up
    single-user.

    The --prefix option to configure changes the root directory for installing
    ncurses; the default is in subdirectories of /usr/, unless the
    configure script finds the `tic' program installed in a different place
    within your path (e.g., finding /usr/bin/tic makes the default prefix
    /usr/bin):

    bin - tic, infocmp, clear, tput
    lib - libncurses*.*
    lib/terminfo - compiled terminal descriptions
    man - man pages
    include - C header files

    If you want to put the terminal descriptions in, for example,
    /usr/share/lib/terminfo, you can either make that a symbolic link to
    /usr/lib/terminfo, or type `configure --with-datadir=/usr/share/lib/terminfo'.
    This is particularly useful if your system already has a terminfo database.
    This option allows you to place ncurses' terminfo in an alternate location.
    You can use TERMINFO to point to the appropriate directory.

2.  Type `configure' to configure ncurses for your operating system and create
    the Makefiles.  You can optionally give configure options, such as
    `--prefix=/usr/local'.  Use `configure --help' to list the available
    options.

    It will create your Makefiles.  If your operating system is not supported,
    read the PORTABILITY section in the file ncurses/README for information on
    how to create a configuration file for your system.

    The `configure' script generates makefile rules for one or more object
    models and their associated libraries:

	libncurses.a (normal)

	libncurses.so (shared)

	libncurses_g.a (debug)

	libncurses_p.a (profile)

    If you do not specify any models, the normal and debug libraries will be
    configured.  This is equivalent to

    	configure --with-normal --with-debug

    Rules for generating shared libraries are highly dependent upon the choice
    of host system and compiler.  We've been testing shared libraries on linux
    and sunos with gcc, but more work needs to be done to make shared libraries
    work on other systems.

    If you have the capability to make a publicly accessible terminfo database,
    use the --disable-termcap switch.  This removes the automatic fallback to
    the termcap file normally compiled in, making the curses library 
    significantly smaller because the initialization code doesn't have to 
    carry around the entire termcap-to-terminfo compiler.

3.  Type `make'.  Ignore any warnings, no error messages should be produced. 
    This should compile the library, the terminfo compiler (tic), the infocmp,
    clear and tput programs (see the man pages for explanation of what they
    do), some test programs, and the panels and menus libraries.
    Read the file test/README for details on the test programs.

4.  IF YOU HAVE ROOT: You can type `make install' to install the libraries,
    the programs, the terminfo database and the man pages.  Alternately, you
    can type `make install' in each directory you want to install.  In the
    top-level directory, you can do a partial install using these commands:
 
	'make install.progs'    installs tic, infocmp, clear and tput.
  	'make install.includes' installs the headers.
  	'make install.libs'     installs the libraries.
  	'make install.data'     installs the terminfo data. (Note: `tic' must
	                        be installed before the terminfo data can be
			        compiled).
	'make install.man'      installs the man pages.

  ############################################################################
  #     CAVEAT EMPTOR: `install.data' run as root will NUKE any existing     #
  #  terminfo database. If you have any custom or unusual entries SAVE them  #
  #  before you install ncurses.  I have a file called terminfo.custom for   #
  #  this purpose.  Don't forget to run tic on the file once you're done.    #
  ############################################################################

    Also note that `tic misc/terminfo.src' uses large amounts of core.
    on machines with less than 16 megabytes of physical RAM and slow disks,
    paging overhead has been known to slow the running time from a few
    minutes to a couple of hours!
 
    We have attacked this problem by breaking the file in half, cutting 
    each section's core requirements drastically (the cut point was chosen
    so there are no `use' references that cross the cut going forward).  

    The terminfo(5) manual page wants to be preprocessed with tbl(1) before
    being formatted by nroff(1).  Modern man(1) implementations tend to do
    this by default, but you may want to look at your version's man page
    to be sure.

    If the system already has a curses library that you need to keep using
    for some bizarre binary-compatibility reason, you'll need to distinguish
    between it and ncurses. If ncurses is installed outside the standard
    directories (/usr/include and /usr/lib) then all your users will need
    to use the -I option to compile programs and -L to link them.

    IF YOU DO NOT HAVE ROOT: Change directory to the `progs' subdirectory
    and run the `capconvert' script.  This script will deduce various things
    about your environment and use them to build you a private terminfo tree,
    so you can use ncurses applications.

    If more than one user at your site does this, the space for the duplicate
    trees is wasted.  Try to get your site administrators to install a system-
    wide terminfo tree instead.

7.  The c++ directory has C++ classes that are built on top of ncurses and
    panels.  You need to have c++ (and its libraries) installed before you can
    compile and run the demo.

8.  If you're running under Linux, you must either (a) tell Linux that the
    console terminal type is `linux', or (b) make a link to or copy of the 
    linux entry in the appropriate place under your terminfo directory,
    named `console'.

    The way to change the wired-in console type is by editing /etc/inittab.
    Warning: this is not for the fainthearted, if you mess up your console
    getty entries you can make your system unusable!  However, if you are
    a distribution maker, this is the right thing to do (see the note for
    integrators near the end of this file).

    The easier way is to link or copy l/linux to c/console under your terminfo
    directory.  Note: this will go away next time you do `make install.data'
    and you'll have to redo it. 

9.  Run ncurses and several other test programs (see the test directory).

    The ncurses program is designed specifically to test the ncurses library.
    You can use it to verify that the screen highlights work correctly, that
    cursor addressing and window scrolling works OK, etc.

NOTES:
	If you have SLS or anything based on it (slackware is OK) PLEASE
	remove everything related to ncurses before re-installing it.

	If you have BSD curses installed in your system and you accidentally
	compile using its curses.h you'll end up with a large number of
	undefined symbols at link time. _waddbytes is one of them.

	The include files will normally be installed in /usr/include/ncurses. 
	To arrange for your programs to see them by default, copy or link them
	to /usr/include from there.

IF YOU ARE A SYSTEM INTEGRATOR:

	Configure with --prefix=/usr to make the install productions put
	libraries and headers in the correct locations (overwriting any
	previous curses libraries and headers).  This will put the terminfo 
	hierarchy under /usr/lib/terminfo; you may want to override this with
	--data-dir=/usr/share/misc/terminfo 

	Please configure the ncurses library in a pure-terminfo mode; that
	is, with the --disable-termcap option.   This will make the curses 
	library smaller and faster. The ncurses library includes a termcap 
	emulation that queries the terminfo database, so even applications 
	that use raw termcap to query terminal characteristics will win 
	(providing you recompile and relink them!).

	In various Linuxes (and possibly elsewhere) there has been a practice
	of designating the system console driver type as `console'.  Please
	do not do this any more!  It complicates peoples' lives, because it
	can mean that several different terminfo entries from different 
	operating systems all logically want to be called `console'.

	Please pick a name unique to your console driver and set that up
	in the /etc/inittab table or local equivalent.  Send the entry to the
	terminfo maintainer (listed in the misc/terminfo file) to be included
	in the terminfo master, if it's not already there.  See the
	term(7) manual page included with this distribution for more on
	conventions for choosing type names.

	Here are our recommended primary console names for the most important
	freeware UNIX distributions:

		linux	-- Linux console driver
		freebsd	-- FreeBSD
		netbsd	-- NetBSD
		bsdos	-- BSD/OS

	If you are responsible for integrating ncurses for one of these
	distribution, please either use the recommended name or get back
	to us explaining why you don't want to, so we can work out nomenclature
	that will make users' lives easier rather than harder.
