9You should be reading the file INSTALL in a directory called ncurses-d.d, where
10d.d is the current version number.  There should be several subdirectories,
11including `c++', `form', `man', `menu', 'misc', `ncurses', `panel', `progs',
12and `test'.  See the README file for a roadmap to the package.
13
14If you are a Linux or FreeBSD or NetBSD distribution integrator or packager,
15please read and act on the section titled IF YOU ARE A SYSTEM INTEGRATOR
16below.
17
18If you are converting from BSD curses and do not have root access, be sure
19to read the BSD CONVERSION NOTES section below.
20
21If you are using a version of XFree86 xterm older than 3.1.2F, see the section
22on RECENT XTERM VERSIONS below.

40i386 Unixes, go read the Portability section in the TO-DO file before you
41do anything else.
42
43REQUIREMENTS:
44
45You will need the following in order to build and install ncurses under UNIX:
46
47	* ANSI C compiler  (gcc is recommended)
48	* sh               (bash will do)
49	* awk              (mawk or gawk will do)
50	* sed
51	* BSD or System V style install (a script is enclosed)
52
53Ncurses has been also built in the OS/2 EMX environment.
54
55INSTALLATION PROCEDURE:
56
571.  First, decide whether you want ncurses to replace your existing library (in
58    which case you'll need super-user privileges) or be installed in parallel
59    with it.
60
61    The --prefix option to configure changes the root directory for installing
62    ncurses.  The default is in subdirectories of /usr/local.  Use
63    --prefix=/usr to replace your default curses distribution.  This is the
64    default for Linux and BSD/OS users.
65
66    The package gets installed beneath the --prefix directory as follows:
67
68    In $(prefix)/bin:          tic, infocmp, captoinfo, tset,
69    				reset, clear, tput, toe
70    In $(prefix)/lib:          libncurses*.* libcurses.a
71    In $(prefix)/share/terminfo: compiled terminal descriptions
72    In $(prefix)/include:      C header files
73    Under $(prefix)/man:       the manual pages
74
75    Note however that the configure script attempts to locate previous
76    installation of ncurses, and will set the default prefix according to where
77    it finds the ncurses headers.
78
792.  Type `./configure' in the top-level directory of the distribution to
80    configure ncurses for your operating system and create the Makefiles.
81    Besides --prefix, various configuration options are available to customize
82    the installation; use `./configure --help' to list the available options.
83
84    If your operating system is not supported, read the PORTABILITY section in
85    the file ncurses/README for information on how to create a configuration
86    file for your system.
87
88    The `configure' script generates makefile rules for one or more object
89    models and their associated libraries:
90
91	libncurses.a (normal)
92
93	libcurses.a (normal, a link to libncurses.a)
94		This gets left out if you configure with --disable-overwrite.
95
96	libncurses.so (shared)
97
98	libncurses_g.a (debug)
99
100	libncurses_p.a (profile)
101
102    If you do not specify any models, the normal and debug libraries will be
103    configured.  Typing `configure' with no arguments is equivalent to:
104
105    	./configure --with-normal --with-debug --enable-overwrite
106
107    Typing
108
109    	./configure --with-shared
110
111    makes the shared libraries the default, resulting in
112
113    	./configure --with-shared --with-normal --with-debug --enable-overwrite
114
115    If you want only shared libraries, type
116
117    	./configure --with-shared --without-normal --without-debug
118
119    Rules for generating shared libraries are highly dependent upon the choice
120    of host system and compiler.  We've been testing shared libraries on Linux
121    and SunOS with gcc, but more work needs to be done to make shared libraries
122    work on other systems.
123
124    You can make curses and terminfo fall back to an existing file of termcap
125    definitions by configuring with --enable-termcap.  If you do this, the
126    library will search /etc/termcap before the terminfo database, and will
127    also interpret the contents of the TERM environment variable.  See the
128    section BSD CONVERSION NOTES below.
129
1303.  Type `make'.  Ignore any warnings, no error messages should be produced.
131    This should compile the ncurses library, the terminfo compiler tic(1),
132    captoinfo(1), infocmp(1), toe(1), clear(1) tset(1), reset(1), and tput(1)
133    programs (see the man pages for explanation of what they do), some test
134    programs, and the panels, menus, and forms libraries.
135
1364.  Run ncurses and several other test programs in the test directory to
137    verify that ncurses functions correctly before doing an install that
138    may overwrite system files.  Read the file test/README for details on
139    the test programs.
140
141    NOTE: You must have installed the terminfo database, or set the
142    environment variable $TERMINFO to point to a SVr4-compatible terminfo
143    database before running the test programs.  Not all vendors' terminfo
144    databases are SVr4-compatible, but most seem to be.  Exceptions include
145    DEC's Digital Unix (formerly known as OSF/1).
146
147    The ncurses program is designed specifically to test the ncurses library.
148    You can use it to verify that the screen highlights work correctly, that
149    cursor addressing and window scrolling works OK, etc.
150
1515.  Once you've tested, you can type `make install' to install libraries,
152    the programs, the terminfo database and the man pages.  Alternately, you
153    can type `make install' in each directory you want to install.  In the
154    top-level directory, you can do a partial install using these commands:
155
156	'make install.progs'    installs tic, infocmp, etc...
157  	'make install.includes' installs the headers.
158  	'make install.libs'     installs the libraries (and the headers).
159  	'make install.data'     installs the terminfo data. (Note: `tic' must
160	                        be installed before the terminfo data can be
161			        compiled).
162	'make install.man'      installs the man pages.
163
164  ############################################################################
165  #     CAVEAT EMPTOR: `install.data' run as root will NUKE any existing     #
166  #  terminfo database. If you have any custom or unusual entries SAVE them  #
167  #  before you install ncurses.  I have a file called terminfo.custom for   #
168  #  this purpose.  Don't forget to run tic on the file once you're done.    #
169  ############################################################################
170
171    The terminfo(5) manual page wants to be preprocessed with tbl(1) before
172    being formatted by nroff(1).  Modern man(1) implementations tend to do
173    this by default, but you may want to look at your version's man page
174    to be sure.
175
176    If the system already has a curses library that you need to keep using
177    for some bizarre binary-compatibility reason, you'll need to distinguish
178    between it and ncurses. If ncurses is installed outside the standard
179    directories (/usr/include and /usr/lib) then all your users will need
180    to use the -I option to compile programs and -L to link them.
181
182    If you have BSD curses installed in your system and you accidentally
183    compile using its curses.h you'll end up with a large number of
184    undefined symbols at link time. _waddbytes is one of them.
185
186    IF YOU DO NOT HAVE ROOT: Change directory to the `progs' subdirectory
187    and run the `capconvert' script.  This script will deduce various things
188    about your environment and use them to build you a private terminfo tree,
189    so you can use ncurses applications.
190
191    If more than one user at your site does this, the space for the duplicate
192    trees is wasted.  Try to get your site administrators to install a system-
193    wide terminfo tree instead.
194
195    See the BSD CONVERSION NOTES section below for a few more details.
196
1976.  The c++ directory has C++ classes that are built on top of ncurses and
198    panels.  You must have c++ (and its libraries) installed before you can
199    compile and run the demo.
200
201    Use --without-cxx-binding to tell configure to not build the C++ bindings
202    and demo.
203
204    If you do not have C++, you must use the --without-cxx option to tell
205    the configure script to not attempt to determine the type of 'bool'
206    which may be supported by C++.  IF YOU USE THIS OPTION, BE ADVISED THAT
207    YOU MAY NOT BE ABLE TO COMPILE (OR RUN) NCURSES APPLICATIONS WITH C++.
208
2097.  If you're running an older Linux, you must either (a) tell Linux that the
210    console terminal type is `linux' or (b) make a link to or copy of the
211    linux entry in the appropriate place under your terminfo directory, named
212    `console'.  All 1.3 and many 1.2 distributions (including Yggdrasil and
213    Red Hat) already have the console type set to `linux'.
214
215    The way to change the wired-in console type depends on the configuration
216    of your system. This may involve editing /etc/inittab, /etc/ttytype,
217    /etc/profile and other such files.
218
219    Warning: this is not for the fainthearted, if you mess up your console
220    getty entries you can make your system unusable!  However, if you are
221    a distribution maker, this is the right thing to do (see the note for
222    integrators near the end of this file).
223
224    The easier way is to link or copy l/linux to c/console under your terminfo
225    directory.  Note: this will go away next time you do `make install.data'
226    and you'll have to redo it. There is no need to have entries for all
227    possible screen sizes, ncurses will figure out the size automatically.
228
229IF YOU ARE A SYSTEM INTEGRATOR:
230
231    Beginning with 1.9.9, the ncurses distribution includes both a tset
232    utility and /usr/share/tabset directory.  If you are installing ncurses,
233    it is no longer either necessary or desirable to install tset-jv.
234
235    Configuration and Installation:
236
237	Configure with --prefix=/usr to make the install productions put
238	libraries and headers in the correct locations (overwriting any
239	previous curses libraries and headers).  This will put the terminfo
240	hierarchy under /usr/share/terminfo; you may want to override this with
241	--datadir=/usr/share/misc; terminfo and tabset are installed under the
242	data directory.
243
244	Please configure the ncurses library in a pure-terminfo mode; that
245	is, with the --disable-termcap option.   This will make the ncurses
246	library smaller and faster. The ncurses library includes a termcap
247	emulation that queries the terminfo database, so even applications
248	that use raw termcap to query terminal characteristics will win
249	(providing you recompile and relink them!).
250
251	If you must configure with termcap fallback enabled, you may also
252	wish to use the --enable-getcap option.  This option speeds up
253	termcap-based startups, at the expense of not allowing personal
254	termcap entries to reference the terminfo tree.  See the code in
255	ncurses/tinfo/read_termcap.c for details.
256
257	Note that if you have $TERMCAP set, ncurses will use that value
258	to locate termcap data.  In particular, running from xterm will
259	set $TERMCAP to the contents of the xterm's termcap entry.
260	If ncurses sees that, it will not examine /etc/termcap.
261
262    Keyboard Mapping:
263
264	The terminfo file assumes that Shift-Tab generates \E[Z (the ECMA-48
265	reverse-tabulation sequence) rather than ^I.  Here are the loadkeys -d
266	mappings that will set this up:
267
268		keycode  15 = Tab             Tab
269			alt     keycode  15 = Meta_Tab
270			shift	keycode  15 = F26
271		string F26 ="\033[Z"
272
273    Naming the Console Terminal
274
275	In various Linuxes (and possibly elsewhere) there has been a practice
276	of designating the system console driver type as `console'.  Please
277	do not do this any more!  It complicates peoples' lives, because it
278	can mean that several different terminfo entries from different
279	operating systems all logically want to be called `console'.
280
281	Please pick a name unique to your console driver and set that up
282	in the /etc/inittab table or local equivalent.  Send the entry to the
283	terminfo maintainer (listed in the misc/terminfo file) to be included
284	in the terminfo file, if it's not already there.  See the
285	term(7) manual page included with this distribution for more on
286	conventions for choosing type names.
287
288	Here are some recommended primary console names:
289
290		linux	-- Linux console driver
291		freebsd	-- FreeBSD
292		netbsd	-- NetBSD
293		bsdos	-- BSD/OS
294
295	If you are responsible for integrating ncurses for one of these
296	distribution, please either use the recommended name or get back
297	to us explaining why you don't want to, so we can work out nomenclature
298	that will make users' lives easier rather than harder.
299
300RECENT XTERM VERSIONS
301	The terminfo database file included with this distribution assumes you
302	are running an XFree86 xterm based on X11R6 (i.e., xterm-r6).  The
303	earlier X11R5 entry (xterm-r5) is provided as well.
304
305	If you are running XFree86 version 3.2 (actually 3.1.2F and up), you
306	should consider using the xterm-xf86-v32 (or later, the most recent
307	version is always named "xterm-xfree86") entry, which adds ANSI color
308	and the VT220 capabilities which have been added in XFree86.  If you
309	are running a mixed network, however, where this terminal description
310	may be used on an older xterm, you may have problems, since
311	applications that assume these capabilities will produce incorrect
312	output on the older xterm (e.g., highlighting is not cleared).
313
314CONFIGURING FALLBACK ENTRIES
315	In order to support operation of ncurses programs before the terminfo
316	tree is accessible (that is, in single-user mode or at OS installation
317	time) the ncurses library can be compiled to include an array of
318	pre-fetched fallback entries.
319
320	These entries are checked by setupterm() only when the conventional
321	fetches from the terminfo tree and the termcap fallback (if configured)
322	have been tried and failed.  Thus, the presence of a fallback will not
323	shadow modifications to the on-disk entry for the same type, when that
324	entry is accessible.
325
326	By default, there are no entries on the fallback list.  After you
327	have built the ncurses suite for the first time, you can change
328	the list (the process needs infocmp(1)).  To do so, use the script
329	MKfallback.sh.  A configure script option --with-fallbacks does this
330	(it accepts a comma-separated list of the names you wish, and does
331	not require a rebuild).
332
333	If you wanted (say) to have linux, vt100, and xterm fallbacks, you
334	would use the commands
335
336		cd ncurses;
337		MKfallback.sh linux vt100 xterm >fallback.c
338
339	Then just rebuild and reinstall the library as you would normally.
340	You can restore the default empty fallback list with
341
342		MKfallback.sh >fallback.c
343
344	The overhead for an empty fallback list is one trivial stub function.
345	Any non-empty fallback list is const-ed and therefore lives in sharable
346	text space.  You can look at the comment trailing each initializer in
347	the generated ncurses/fallback.c file to see the core cost of the
348	fallbacks.  A good rule of thumb for modern vt100-like entries is that
349	each one will cost about 2.5K of text space.
350
351BSD CONVERSION NOTES:
352	If you need to support really ancient BSD programs, you probably
353	want to configure with the --enable-bsdpad option.  What this does
354	is enable code in tputs() that recognizes a numeric prefix on a
355	capability as a request for that much trailing padding in milliseconds.
356	There are old BSD programs that do things like tputs("50").
357
358	(If you are distributing ncurses as a support-library component of
359	an application you probably want to put the remainder of this section
360	in the package README file.)
361
362        The following note applies only if you have configured ncurses with
363	--enable-termcap.
364
365------------------------------- CUT HERE --------------------------------
366
367If you are installing this application privately (either because you
368have no root access or want to experiment with it before doing a root
369installation), there are a couple of details you need to be aware of.
370They have to do with the ncurses library, which uses terminfo rather
371than termcap for describing terminal characteristics.
372
373Though the ncurses library is terminfo-based, it will interpret your
374TERMCAP variable (if present), any local termcap files you reference
375through it, and the system termcap file.  However, in order to avoid
376slowing down your application startup, it will only do this once per
377terminal type!
378
379The first time you load a given terminal type from your termcap
380database, the library initialization code will automatically write it
381in terminfo format to a subdirectory under $HOME/.terminfo.  After
382that, the initialization code will find it there and do a (much
383faster) terminfo fetch.
384
385Usually, all this means is that your home directory will silently grow
386an invisible .terminfo subdirectory which will get filled in with
387terminfo descriptions of terminal types as you invoke them.  If anyone
388ever installs a global terminfo tree on your system, this will quietly
389stop happening and your $HOME/.terminfo will become redundant.
390
391The objective of all this logic is to make converting from BSD termcap
392as painless as possible without slowing down your application (termcap
393compilation is expensive).
394
395If you don't have a TERMCAP variable or custom personal termcap file,
396you can skip the rest of this dissertation.
397
398If you *do* have a TERMCAP variable and/or a custom personal termcap file
399that defines a terminal type, that definition will stop being visible
400to this application after the first time you run it, because it will
401instead see the terminfo entry that it wrote to $HOME/terminfo the
402first time around.
403
404Subsequently, editing the TERMCAP variable or personal TERMCAP file
405will have no effect unless you explicitly remove the terminfo entry
406under $HOME/terminfo.  If you do that, the entry will be recompiled
407from your termcap resources the next time it is invoked.
408
409To avoid these complications, use infocmp(1) and tic(1) to edit the
410terminfo directory directly.
411
412------------------------------- CUT HERE --------------------------------
413
414USING NCURSES WITH AFS:
415	AFS treats each directory as a separate logical filesystem, you
416	can't hard-link across them.  The --enable-symlinks option copes
417	with this by making tic use symbolic links.
418
419USING NCURSES WITH EMACS:
420	GNU Emacs has its own termcap support.  By default, it uses a mixture
421	of those functions and code linked from the host system's libraries.
422	You need to foil this and shut out the GNU termcap library entirely.
423
424	In order to do this, hack the Linux config file (s/linux.h) to contain
425	a #define TERMINFO and set the symbol LIBS_TERMCAP to "-lncurses".
426
427	We have submitted such a change for the 19.30 release, so it may
428	already be applied in your sources -- check for the #define TERMINFO.
429
430USING NCURSES WITH GPM:
431	Ncurses 4.1 and up can be configured to use GPM (General Purpose Mouse)
432	which is used on Linux console.  Be aware that GPM is commonly
433	installed as a shared library which contains a wrapper for the curses
434	wgetch() function (libcurses.o).  Some integrators have simplified
435	linking applications by combining all of libcurses.so (the BSD curses)
436	into the libgpm.so file, producing symbol conflicts with ncurses.  You
437	may be able to work around this problem by linking as follows:
438
439		cc -o foo foo.o -lncurses -lgpm -lncurses
440
441	but the linker may not cooperate, producing mysterious errors.
442	A patched version of gpm is available:
443
444		ftp.clark.net:/pub/dickey/ncurses/gpm-1.10-970125.tgz
445
446	This patch is incorporated in gpm 1.12; however some integrators
447	are slow to update this library.
448
449USING NCURSES WITH ELVIS:
450	To use ncurses as the screen-painting library for Elvis, apply the
451	following patch to the Elvis curses
