30 How to install Ncurses/Terminfo on your system
31 ---------------------------------------------------------------------
33 ************************************************************
34 * READ ALL OF THIS FILE BEFORE YOU TRY TO INSTALL NCURSES. *
35 ************************************************************
37 You should be reading the file INSTALL in a directory called ncurses-d.d, where
38 d.d is the current version number. There should be several subdirectories,
39 including `c++', `form', `man', `menu', 'misc', `ncurses', `panel', `progs',
40 and `test'. See the README file for a roadmap to the package.
42 If you are a Linux or FreeBSD or NetBSD distribution integrator or packager,
43 please read and act on the section titled IF YOU ARE A SYSTEM INTEGRATOR
46 If you are converting from BSD curses and do not have root access, be sure
47 to read the BSD CONVERSION NOTES section below.
49 If you are trying to build applications using gpm with ncurses,
50 read the USING NCURSES WITH GPM section below.
52 If you are running over the Andrew File System see the note below on
53 USING NCURSES WITH AFS.
55 If you are cross-compiling, see the note below on BUILDING NCURSES WITH A
58 If you want to build the Ada95 binding, go to the Ada95 directory and
59 follow the instructions there. The Ada95 binding is not covered below.
61 If you are using anything but (a) Linux, or (b) one of the 4.4BSD-based
62 i386 Unixes, go read the Portability section in the TO-DO file before you
69 You will need the following to build and install ncurses under UNIX:
71 * ANSI C compiler (gcc, for instance)
73 * awk (mawk or gawk will do)
75 * BSD or System V style install (a script is enclosed)
77 Ncurses has been also built in the OS/2 EMX environment.
80 INSTALLATION PROCEDURE:
81 ----------------------
83 1. First, decide whether you want ncurses to replace your existing library (in
84 which case you'll need super-user privileges) or be installed in parallel
87 The --prefix option to configure changes the root directory for installing
88 ncurses. The default is normally in subdirectories of /usr/local, except
89 for systems where ncurses is normally installed as a system library, e.g.,
90 Linux, the various BSD systems and Cygwin. Use --prefix=/usr to replace
91 your default curses distribution.
93 The package gets installed beneath the --prefix directory as follows:
95 In $(prefix)/bin: tic, infocmp, captoinfo, tset,
96 reset, clear, tput, toe
97 In $(prefix)/lib: libncurses*.* libcurses.a
98 In $(prefix)/share/terminfo: compiled terminal descriptions
99 In $(prefix)/include: C header files
100 Under $(prefix)/man: the manual pages
102 Note that the configure script attempts to locate previous installation of
103 ncurses, and will set the default prefix according to where it finds the
106 Do not use commands such as
108 make install prefix=XXX
110 to change the prefix after configuration, since the prefix value is used
111 for some absolute pathnames such as TERMINFO. Instead do this
113 make install DESTDIR=XXX
115 See also the discussion of --with-install-prefix.
117 2. Type `./configure' in the top-level directory of the distribution to
118 configure ncurses for your operating system and create the Makefiles.
119 Besides --prefix, various configuration options are available to customize
120 the installation; use `./configure --help' to list the available options.
122 If your operating system is not supported, read the PORTABILITY section in
123 the file ncurses/README for information on how to create a configuration
124 file for your system.
126 The `configure' script generates makefile rules for one or more object
127 models and their associated libraries:
129 libncurses.a (normal)
131 libcurses.a (normal, a link to libncurses.a)
132 This gets left out if you configure with --disable-overwrite.
134 libncurses.so (shared)
136 libncurses_g.a (debug)
138 libncurses_p.a (profile)
140 libncurses.la (libtool)
142 If you configure using the --enable-widec option, a "w" is appended to the
143 library names (e.g., libncursesw.a), and the resulting libraries support
144 wide-characters, e.g., via a UTF-8 locale. The corresponding header files
145 are compatible with the non-wide-character configuration; wide-character
146 features are provided by ifdef's in the header files. The wide-character
147 library interfaces are not binary-compatible with the non-wide-character
148 version. Building and running the wide-character code relies on a fairly
149 recent implementation of libiconv. We have built this configuration on
150 Linux using libiconv, sometimes requiring libutf8.
152 If you configure using the --with-pthread option, a "t" is appended to
153 the library names (e.g., libncursest.a, libncursestw.a).
155 If you do not specify any models, the normal and debug libraries will be
156 configured. Typing `configure' with no arguments is equivalent to:
158 ./configure --with-normal --with-debug --enable-overwrite
162 ./configure --with-shared
164 makes the shared libraries the default, resulting in
166 ./configure --with-shared --with-normal --with-debug --enable-overwrite
168 If you want only shared libraries, type
170 ./configure --with-shared --without-normal --without-debug
172 Rules for generating shared libraries are highly dependent upon the choice
173 of host system and compiler. We've been testing shared libraries on Linux
174 and SunOS with gcc, but more work needs to be done to make shared libraries
175 work on other systems.
177 If you have libtool installed, you can type
179 ./configure --with-libtool
181 to generate the appropriate static and/or shared libraries for your
182 platform using libtool.
184 You can make curses and terminfo fall back to an existing file of termcap
185 definitions by configuring with --enable-termcap. If you do this, the
186 library will search /etc/termcap before the terminfo database, and will
187 also interpret the contents of the TERM environment variable. See the
188 section BSD CONVERSION NOTES below.
190 3. Type `make'. Ignore any warnings, no error messages should be produced.
191 This should compile the ncurses library, the terminfo compiler tic(1),
192 captoinfo(1), infocmp(1), toe(1), clear(1) tset(1), reset(1), and tput(1)
193 programs (see the manual pages for explanation of what they do), some test
194 programs, and the panels, menus, and forms libraries.
196 4. Run ncurses and several other test programs in the test directory to
197 verify that ncurses functions correctly before doing an install that
198 may overwrite system files. Read the file test/README for details on
201 NOTE: You must have installed the terminfo database, or set the
202 environment variable $TERMINFO to point to a SVr4-compatible terminfo
203 database before running the test programs. Not all vendors' terminfo
204 databases are SVr4-compatible, but most seem to be. Exceptions include
205 DEC's Digital Unix (formerly known as OSF/1).
207 If you run the test programs WITHOUT installing terminfo, ncurses may
208 read the termcap file and cache that in $HOME/.terminfo, which will
209 thereafter be used instead of the terminfo database. See the comments
210 on "--enable-getcap-cache", to see why this is a Bad Thing.
212 It is possible to configure ncurses to use other terminfo database formats.
213 A few are provided as examples in the include-directory (see --with-caps).
215 The ncurses program is designed specifically to test the ncurses library.
216 You can use it to verify that the screen highlights work correctly, that
217 cursor addressing and window scrolling works OK, etc.
219 5. Once you've tested, you can type `make install' to install libraries,
220 the programs, the terminfo database and the manual pages. Alternately, you
221 can type `make install' in each directory you want to install. In the
222 top-level directory, you can do a partial install using these commands:
224 'make install.progs' installs tic, infocmp, etc...
225 'make install.includes' installs the headers.
226 'make install.libs' installs the libraries (and the headers).
227 'make install.data' installs the terminfo data. (Note: `tic' must
228 be installed before the terminfo data can be
230 'make install.man' installs the manual pages.
232 ############################################################################
233 # CAVEAT EMPTOR: `install.data' run as root will NUKE any existing #
234 # terminfo database. If you have any custom or unusual entries SAVE them #
235 # before you install ncurses. I have a file called terminfo.custom for #
236 # this purpose. Don't forget to run tic on the file once you're done. #
237 ############################################################################
239 The terminfo(5) manual page must be preprocessed with tbl(1) before
240 being formatted by nroff(1). Modern man(1) implementations tend to do
241 this by default, but you may want to look at your version's manual page
242 to be sure. You may also install the manual pages after preprocessing
243 with tbl(1) by specifying the configure option --with-manpage-tbl.
245 If the system already has a curses library that you need to keep using
246 you'll need to distinguish between it and ncurses. See the discussion of
247 --disable-overwrite. If ncurses is installed outside the standard
248 directories (/usr/include and /usr/lib) then all your users will need to
249 use the -I option to compile programs and -L to link them.
251 If you have another curses installed in your system and you accidentally
252 compile using its curses.h you'll end up with a large number of
253 undefined symbols at link time.
255 IF YOU DO NOT HAVE ROOT: Change directory to the `progs' subdirectory
256 and run the `capconvert' script. This script will deduce various things
257 about your environment and use them to build you a private terminfo tree,
258 so you can use ncurses applications.
260 If more than one user at your site does this, the space for the duplicate
261 trees is wasted. Try to get your site administrators to install a system-
262 wide terminfo tree instead.
264 See the BSD CONVERSION NOTES section below for a few more details.
266 6. The c++ directory has C++ classes that are built on top of ncurses and
267 panels. You must have c++ (and its libraries) installed before you can
268 compile and run the demo.
270 Use --without-cxx-binding to tell configure to not build the C++ bindings
273 If you do not have C++, you must use the --without-cxx option to tell
274 the configure script to not attempt to determine the type of 'bool'
275 which may be supported by C++. IF YOU USE THIS OPTION, BE ADVISED THAT
276 YOU MAY NOT BE ABLE TO COMPILE (OR RUN) NCURSES APPLICATIONS WITH C++.
279 SUMMARY OF CONFIGURE OPTIONS:
280 ----------------------------
282 The configure script provides a short list of its options when you type
286 The --help and several options are common to all configure scripts that are
287 generated with autoconf. Those are all listed before the line
289 --enable and --with options recognized:
291 The other options are specific to this package. We list them in alphabetic
294 --disable-assumed-color
295 With ncurses 5.1, we introduced a new function, assume_default_colors()
296 which allows applications to specify what the default foreground and
297 background color are assumed to be. Most color applications use
298 full-screen color; but a few do not color the background. While the
299 assumed values can be overridden by invoking assume_default_colors(),
300 you may find it useful to set the assumed values to the pre-5.1
301 convention, using this configure option.
304 Assume machine has little memory. The configure script attempts to
305 determine if your machine has enough memory (about 6Mb) to compile the
306 terminfo database without writing portions to disk. Some allocators
307 return deceptive results, so you may have to override the configure
308 script. Or you may be building tic for a smaller machine.
310 --disable-big-strings
311 Disable compile-time optimization of predefined tables which puts
312 all of their strings into a very long string, to reduce relocation
316 Use only built-in data. The ncurses libraries normally read terminfo
317 and termcap data from disk. You can configure ncurses to have a
318 built-in database, aka "fallback" entries. Embedded applications may
319 have no need for an external database. Some, but not all of the
320 programs are useful in this configuration, e.g., reset and tput versus
324 Disable function-extensions. Configure ncurses without the functions
325 that are not specified by XSI. See ncurses/modules for the exact
326 list of library modules that would be suppressed.
329 Compile without hashmap scrolling-optimization code. This algorithm is
332 --disable-home-terminfo
333 The $HOME/.terminfo directory is normally added to ncurses' search
334 list for reading/writing terminfo entries, since that directory is
335 more likely writable than the system terminfo database. Use this
336 option to disable the feature altogether.
339 Disable compiler flags needed to use large-file interfaces.
342 For testing, compile-in code that frees memory that normally would not
343 be freed, to simplify analysis of memory-leaks.
345 Any implementation of curses must not free the memory associated with
346 a screen, since (even after calling endwin()), it must be available
347 for use in the next call to refresh(). There are also chunks of
348 memory held for performance reasons. That makes it hard to analyze
349 curses applications for memory leaks. To work around this, build
350 a debugging version of the ncurses library which frees those chunks
351 which it can, and provides the _nc_free_and_exit() function to free
352 the remainder on exit. The ncurses utility and test programs use this
353 feature, e.g., via the ExitProgram() macro.
356 The header files will ignore use of the _LP64 symbol to make chtype
357 and mmask_t types 32 bits (they may be long on 64-bit hosts, for
358 compatibility with older releases).
360 NOTE: this is potentially an ABI change, depending on existing
361 packages. The default for this option is "disabled" for ncurses
362 ABI 5, and "enabled" for ABI 6.
365 For testing, use functions rather than macros. The program will run
366 more slowly, but it is simpler to debug. This defines NCURSES_NOMACROS
367 at build time. See also the --enable-expanded option.
370 If you are installing ncurses on a system which contains another
371 development version of curses, or which could be confused by the loader
372 for another version, we recommend that you leave out the link to
373 -lcurses. The ncurses library is always available as -lncurses.
374 Disabling overwrite also causes the ncurses header files to be
375 installed into a subdirectory, e.g., /usr/local/include/ncurses,
376 rather than the include directory. This makes it simpler to avoid
377 compile-time conflicts with other versions of curses.h
380 If --enable-rpath is given, the generated makefiles normally will
381 rebuild the libraries during install. Use this option to simply
382 copy whatever the linked produced.
384 This option is ignored if --enable-rpath is not given.
386 --disable-root-environ
387 Compile with environment restriction, so certain environment variables
388 are not available when running as root, or via a setuid/setgid
389 application. These are (for example $TERMINFO) those that allow the
390 search path for the terminfo or termcap entry to be customized.
392 --disable-scroll-hints
393 Compile without scroll-hints code. This option is ignored when
394 hashmap scrolling is configured, which is the default.
396 --disable-tparm-varargs
397 Portable programs should call tparm() using the fixed-length parameter
398 list documented in X/Open. ncurses provides varargs support for this
399 function. Use --disable-tparm-varargs to disable this support.
402 For testing, compile-in assertion code. This is used only for a few
403 places where ncurses cannot easily recover by returning an error code.
405 --enable-broken_linker
406 A few platforms have what we consider a broken linker: it cannot link
407 objects from an archive solely by referring to data objects in those
408 files, but requires a function reference. This configure option
409 changes several data references to functions to work around this
412 NOTE: With ncurses 5.1, this may not be necessary, since we are
413 told that some linkers interpret uninitialized global data as a
414 different type of reference which behaves as described above. We have
415 explicitly initialized all of the global data to work around the
419 Recognize BSD-style prefix padding. Some ancient BSD programs (such as
420 nethack) call tputs("50") to implement delays.
423 Compile with experimental $COLORFGBG code. That environment variable
424 is set by some terminal emulators as a hint to applications, by
425 advertising the default foreground and background colors. During
426 initialization, ncurses sets color pair 0 to match this.
429 The curses interface as documented in XSI is rather old, in fact
430 including features that precede ANSI C. The prototypes generally do
431 not make effective use of "const". When using stricter compilers (or
432 gcc with appropriate warnings), you may see warnings about the mismatch
433 between const and non-const data. We provide a configure option which
434 changes the interfaces to use const - quieting these warnings and
435 reflecting the actual use of the parameters more closely. The ncurses
436 library uses the symbol NCURSES_CONST for these instances of const,
437 and if you have asked for compiler warnings, will add gcc's const-qual
438 warning. There will still be warnings due to subtle inconsistencies
439 in the interface, but at a lower level.
441 NOTE: configuring ncurses with this option may detract from the
442 portability of your applications by encouraging you to use const in
443 places where the XSI curses interface would not allow them. Similar
444 issues arise when porting to SVr4 curses, which uses const in even
448 Use the option --disable-echo to make the build-log less verbose by
449 suppressing the display of the compile and link commands. This makes
450 it easier to see the compiler warnings. (You can always use "make -n"
451 to see the options that are used).
454 For testing, generate functions for certain macros to make them visible
455 as such to the debugger. See also the --disable-macros option.
458 Extend the cchar_t structure to allow more than 16 colors to be
459 encoded. This applies only to the wide-character (--enable-widec)
462 NOTE: using this option will make libraries which are not binary-
463 compatible with libncursesw 5.4. None of the interfaces change, but
464 applications which have an array of cchar_t's must be recompiled.
467 Modify the encoding of mouse state to make room for a 5th mouse button.
468 That allows one to use ncurses with a wheel mouse with xterm or
469 similar X terminal emulators.
471 NOTE: using this option will make libraries which are not binary-
472 compatible with libncursesw 5.4. None of the interfaces change, but
473 applications which have mouse mask mmask_t's must be recompiled.
476 Use the 4.4BSD getcap code if available, or a bundled version of it to
477 fetch termcap entries. Entries read in this way cannot use (make
478 cross-references to) the terminfo tree, but it is faster than reading
481 If configured for one of the *BSD systems, this automatically uses
482 the hashed database system produced using cap_mkdb or similar tools.
483 In that case, there is no advantage in using the --enable-getcap-cache
486 See also the --with-hashed-db option.
488 --enable-getcap-cache
489 Cache translated termcaps under the directory $HOME/.terminfo
491 NOTE: this sounds good - it makes ncurses run faster the second time.
492 But look where the data comes from - an /etc/termcap containing lots of
493 entries that are not up to date. If you configure with this option and
494 forget to install the terminfo database before running an ncurses
495 application, you will end up with a hidden terminfo database that
496 generally does not support color and will miss some function keys.
499 Compile-in cursor-optimization code that uses hard-tabs. We would make
500 this a standard feature except for the concern that the terminfo entry
501 may not be accurate, or that your stty settings have disabled the use
505 Controls whether the filesystem on which the terminfo database resides
506 supports mixed-case filenames (normal for UNIX, but not on other
507 systems). If you do not specify this option, the configure script
508 checks the current filesystem.
511 Compile-in support for the $NCURSES_NO_PADDING environment variable,
512 which allows you to suppress the effect of non-mandatory padding in
513 terminfo entries. This is the default, unless you have disabled the
517 Compile experimental configuration which improves reentrant use of the
518 library by reducing global and static variables. This option is also
519 set if --with-pthread is used.
522 Use rpath option when generating shared libraries, and (with some
523 restrictions) when linking the corresponding programs. This originally
524 (in 1997) applied mainly to systems using the GNU linker (read the
527 More recently it is useful for systems that require special treatment
528 shared libraries in "unusual" locations. The "system" libraries reside
529 in directories which are on the loader's default search-path. While
530 you may be able to use workarounds such as the $LD_LIBRARY_PATH
531 environment variable, they do not work with setuid applications since
532 the LD_LIBRARY_PATH variable would be unset in that situation.
534 This option does not apply to --with-libtool, since libtool makes
535 extra assumptions about rpath.
537 --enable-safe-sprintf
538 Compile with experimental safe-sprintf code. You may consider using
539 this if you are building ncurses for a system that has neither
540 vsnprintf() or vsprintf(). It is slow, however.
543 Compile support for ncurses' SIGWINCH handler. If your application has
544 its own SIGWINCH handler, ncurses will not use its own. The ncurses
545 handler causes wgetch() to return KEY_RESIZE when the screen-size
546 changes. This option is the default, unless you have disabled the
550 The term.h header declares a Booleans[] array typed "char". But it
551 stores signed values there and "char" is not necessarily signed.
552 Some packagers choose to alter the type of Booleans[] though this
553 is not strictly compatible. This option allows one to implement this
554 alteration without patching the source code.
557 If your system supports symbolic links, make tic use symbolic links
558 rather than hard links to save diskspace when writing aliases in the
562 Compile-in support for user-definable terminal capabilities. Use the
563 -x option of tic and infocmp to treat unrecognized terminal
564 capabilities as user-defined strings. This option is the default,
565 unless you have disabled the extended functions.
568 Compile in support for reading terminal descriptions from termcap if no
569 match is found in the terminfo database. See also the --enable-getcap
570 and --enable-getcap-cache options.
573 Turn on GCC compiler warnings. There should be only a few.
575 --enable-weak-symbols
576 If the --with-pthread option is set, check if the compiler supports
577 weak-symbols. If it does, then name the thread-capable library without
578 the "t" (libncurses rather than libncursest), and provide for
579 dynamically loading the pthreads entrypoints at runtime. This allows
580 one to reduce the number of library files for ncurses.
582 --enable-wgetch-events
583 Compile with experimental wgetch-events code. See ncurses/README.IZ
586 Compile with wide-character code. This makes a different version of
587 the libraries (e.g., libncursesw.so), which stores characters as
590 NOTE: applications compiled with this configuration are not compatible
591 with those built for 8-bit characters. You cannot simply make a
592 symbolic link to equate libncurses.so with libncursesw.so
594 NOTE: the Ada95 binding may be built against either version of the the
595 ncurses library, but you must decide which: the binding installs the
596 same set of files for either version. Currently (2002/6/22) it does
597 not use the extended features from the wide-character code, so it is
598 probably better to not install the binding for that configuration.
601 Compile-in support experimental xmc (magic cookie) code.
603 --with-abi-version=NUM
604 Override the ABI version, which is used in shared library filenames.
605 Normally this is the same as the release version; some ports have
606 special requirements for compatibility.
608 --with-ada-compiler=CMD
609 Specify the Ada95 compiler command (default "gnatmake")
611 --with-ada-include=DIR
612 Tell where to install the Ada includes (default:
613 PREFIX/lib/ada/adainclude)
615 --with-ada-objects=DIR
616 Tell where to install the Ada objects (default: PREFIX/lib/ada/adalib)
619 If --without-cxx is specified, override the type used for the "bool"
620 declared in curses.h (normally the type is automatically chosen to
621 correspond with that in <stdbool.h>, or defaults to platform-specific
625 If cross-compiling, specify a host C compiler, which is needed to
626 compile a few utilities which generate source modules for ncurses.
627 If you do not give this option, the configure script checks if the
628 $BUILD_CC variable is set, and otherwise defaults to gcc or cc.
630 --with-build-cflags=XXX
631 If cross-compiling, specify the host C compiler-flags. You might need
632 to do this if the target compiler has unusual flags which confuse the
635 You can also set the environment variable $BUILD_CFLAGS rather than
638 --with-build-cppflags=XXX
639 If cross-compiling, specify the host C preprocessor-flags. You might
640 need to do this if the target compiler has unusual flags which confuse
643 You can also set the environment variable $BUILD_CPPFLAGS rather than
646 --with-build-ldflags=XXX
647 If cross-compiling, specify the host linker-flags. You might need to
648 do this if the target linker has unusual flags which confuse the host
651 You can also set the environment variable $BUILD_LDFLAGS rather than
654 --with-build-libs=XXX
655 If cross-compiling, the host libraries. You might need to do this if
656 the target environment requires unusual libraries.
658 You can also set the environment variable $BUILD_LIBS rather than
662 Specify an alternate terminfo capabilities file, which makes the
663 configure script look for "include/Caps.XXX". A few systems, e.g.,
664 AIX 4.x use the same overall file-format as ncurses for terminfo
665 data, but use different alignments within the tables to support
666 legacy applications. For those systems, you can configure ncurses
667 to use a terminfo database which is compatible with the native
671 Override type of chtype, which stores the video attributes and (if
672 --enable-widec is not given) a character. Prior to ncurses 5.5, this
673 was always unsigned long, but with ncurses 5.5, it may be unsigned.
674 Use this option if you need to preserve compatibility with 64-bit
678 Specify the terminfo source file to install. Usually you will wish
679 to install ncurses' default (misc/terminfo.src). Certain systems
680 have special requirements, e.g, OS/2 EMX has a customized terminfo
684 For testing, compile and link with Conor Cahill's dbmalloc library.
685 This also sets the --disable-leaks option.
688 Generate debug-libraries (default). These are named by adding "_g"
689 to the root, e.g., libncurses_g.a
691 --with-default-terminfo-dir=XXX
692 Specify the default terminfo database directory. This is normally
693 DATADIR/terminfo, e.g., /usr/share/terminfo.
696 For testing, compile and link with Gray Watson's dmalloc library.
697 This also sets the --disable-leaks option.
700 Specify a list of fallback terminal descriptions which will be
701 compiled into the ncurses library. See CONFIGURING FALLBACK ENTRIES.
704 use Alessandro Rubini's GPM library to provide mouse support on the
705 Linux console. Prior to ncurses 5.5, this introduced a dependency on
708 Currently ncurses uses the dlsym() function to bind to the library at
709 runtime, so it is only necessary that the library be present when
710 ncurses is built, to obtain the filename (or soname) used in the
711 corresponding dlopen() call. If you give a value for this option,
714 --with-gpm=$HOME/tmp/test-gpm.so
716 that overrides the configure check for the soname.
718 See also --without-dlsym
720 --with-hashed-db[=XXX]
721 Use a hashed database for storing terminfo data rather than storing
722 each compiled entry in a separate binary file within a directory
725 In particular, this uses the Berkeley database 1.8.5 interface, as
726 provided by that and its successors db 2, 3, and 4. The actual
727 interface is slightly different in the successor versions of the
728 Berkeley database. The database should have been configured using
729 "--enable-compat185".
731 If you use this option for configuring ncurses, tic will only be able
732 to write entries in the hashed database. infocmp can still read
733 entries from a directory tree as well as reading entries from the
734 hashed database. To do this, infocmp determines whether the $TERMINFO
735 variable points to a directory or a file, and reads the directory-tree
736 or hashed database respectively.
738 You cannot have a directory containing both hashed-database and
739 filesystem-based terminfo entries.
741 Use the parameter value to give the install-prefix used for the
743 --with-hashed-db=/usr/local/BigBase
744 to find the corresponding include- and lib-directories under the
747 See also the --enable-getcap option.
749 --with-install-prefix=XXX
750 Allows you to specify an alternate location for installing ncurses
751 after building it. The value you specify is prepended to the "real"
752 install location. This simplifies making binary packages. The
753 makefile variable DESTDIR is set by this option. It is also possible
755 make install DESTDIR=XXX
756 since the makefiles pass that variable to subordinate makes.
758 NOTE: a few systems build shared libraries with fixed pathnames; this
759 option probably will not work for those configurations.
762 Generate libraries with libtool. If this option is selected, then it
763 overrides all other library model specifications. Note that libtool
764 must already be installed, uses makefile rules dependent on GNU make,
765 and does not promise to follow the version numbering convention of
766 other shared libraries on your system. However, if the --with-shared
767 option does not succeed, you may get better results with this option.
769 If a parameter value is given, it must be the full pathname of the
770 particular version of libtool, e.g.,
771 /usr/bin/libtool-1.2.3
773 It is possible to rebuild the configure script to use the automake
774 macros for libtool, e.g., AC_PROG_LIBTOOL. See the comments in
775 aclocal.m4 for CF_PROG_LIBTOOL, and ensure that you build configure
776 using the appropriate patch for autoconf from
777 http://invisible-island.net/autoconf/
779 --with-manpage-aliases
780 Tell the configure script you wish to create entries in the
781 man-directory for aliases to manpages which list them, e.g., the
782 functions in the panel manpage. This is the default. You can disable
783 it if your man program does this. You can also disable
784 --with-manpage-symlinks to install files containing a ".so" command
785 rather than symbolic links.
787 --with-manpage-format=XXX
788 Tell the configure script how you would like to install man-pages. The
789 option value must be one of these: gzip, compress, BSDI, normal,
790 formatted. If you do not give this option, the configure script
791 attempts to determine which is the case.
793 --with-manpage-renames=XXX
794 Tell the configure script that you wish to rename the manpages while
795 installing. Currently the only distribution which does this is
796 the Linux Debian. The option value specifies the name of a file
797 that lists the renamed files, e.g., $srcdir/man/man_db.renames
799 --with-manpage-symlinks
800 Tell the configure script that you wish to make symbolic links in the
801 man-directory for aliases to the man-pages. This is the default, but
802 can be disabled for systems that provide this automatically. Doing
803 this on systems that do not support symbolic links will result in
804 copying the man-page for each alias.
807 Tell the configure script that you with to preprocess the manpages
808 by running them through tbl to generate tables understandable by
812 Override type of mmask_t, which stores the mouse mask. Prior to
813 ncurses 5.5, this was always unsigned long, but with ncurses 5.5, it
814 may be unsigned. Use this option if you need to preserve compatibility
815 with 64-bit executables.
818 Generate normal (i.e., static) libraries (default).
820 Note: on Linux, the configure script will attempt to use the GPM
821 library via the dlsym() function call. Use --without-dlsym to disable
822 this feature, or --without-gpm, depending on whether you wish to use
826 Override type of ospeed variable, which is part of the termcap
827 compatibility interface. In termcap, this is a 'short', which works
828 for a wide range of baudrates because ospeed is not the actual speed
829 but the encoded value, e.g., B9600 would be a small number such as 13.
830 However the encoding scheme originally allowed for values "only" up to
831 38400bd. A newer set of definitions past 38400bd is not encoded as
832 compactly, and is not guaranteed to fit into a short (see the function
833 cfgetospeed(), which returns a speed_t for this reason). In practice,
834 applications that required knowledge of the ospeed variable, i.e.,
835 those using termcap, do not use the higher speeds. Your application
836 (or system, in general) may or may not.
839 Generate profile-libraries These are named by adding "_p" to the root,
843 Link with POSIX threads, set --enable-reentrant. The use_window() and
844 use_screen() functions will use mutex's, allowing rudimentary support
845 for multithreaded applications.
848 Compile-in RCS identifiers. Most of the C files have an identifier.
850 --with-rel-version=NUM
851 Override the release version, which may be used in shared library
852 filenames. This consists of a major and minor version number separated
853 by ".". Normally the major version number is the same as the ABI
854 version; some ports have special requirements for compatibility.
857 Generate shared-libraries. The names given depend on the system for
858 which you are building, typically using a ".so" suffix, along with
859 symbolic links that refer to the release version.
861 NOTE: Unless you override the configure script by setting the $CFLAGS
862 environment variable, these will not be built with the -g debugging
865 NOTE: For some configurations, e.g., installing a new version of
866 ncurses shared libraries on a machine which already has ncurses
867 shared libraries, you may encounter problems with the linker.
868 For example, it may prevent you from running the build tree's
869 copy of tic (for installing the terminfo database) because it
870 loads the system's copy of the ncurses shared libraries. In that
871 case, using the misc/shlib script may be helpful, since it sets
872 $LD_LIBRARY_PATH to point to the build tree, e.g.,
873 ./misc/shlib make install
875 --with-shlib-version=XXX
876 Specify whether to use the release or ABI version for shared libraries.
877 This is normally chosen automatically based on the type of system
878 which you are building on. We use it for testing the configure script.
881 use FreeBSD sysmouse interface provide mouse support on the console.
883 --with-system-type=XXX
884 For testing, override the derived host system-type which is used to
885 decide things such as the linker commands used to build shared
886 libraries. This is normally chosen automatically based on the type of
887 system which you are building on. We use it for testing the configure
890 --with-terminfo-dirs=XXX
891 Specify a search-list of terminfo directories which will be compiled
892 into the ncurses library (default: DATADIR/terminfo)
895 When building the ncurses library, organize this as two parts: the
896 curses library (libncurses) and the low-level terminfo library
897 (libtinfo). This is done to accommodate applications that use only
898 the latter. The terminfo library is about half the size of the total.
900 If an option value is given, that overrides the name of the terminfo
901 library. For instance, if the wide-character version is built, the
902 terminfo library would be named libtinfow. But the libtinfow interface
903 is upward compatible from libtinfo, so it would be possible to overlay
904 libtinfo.so with a "wide" version of libtinfow.so by renaming it with
908 Specify a search-list of termcap files which will be compiled into the
909 ncurses library (default: /etc/termcap:/usr/share/misc/termcap)
912 When building the ncurses library, build a separate library for
913 the modules that are used only by the utility programs. Normally
914 those would be bundled with the termlib or ncurses libraries.
916 If an option value is given, that overrides the name of the tic
917 library. As in termlib, there is no ABI difference between the
918 "wide" libticw.so and libtic.so
920 NOTE: Overriding the name of the tic library may be useful if you are
921 also using the --with-termlib option to rename libtinfo. If you are
922 not doing that, renaming the tic library can result in conflicting
923 library dependencies for tic and other programs built with the tic
927 Configure the trace() function as part of the all models of the ncurses
928 library. Normally it is part of the debug (libncurses_g) library only.
931 For testing, compile with debug option.
932 This also sets the --disable-leaks option.
935 Suppress the configure script's check for Ada95, do not build the
936 Ada95 binding and related demo.
939 Don't install the ncurses header with the name "curses.h". Rather,
940 install as "ncurses.h" and modify the installed headers and manpages
944 XSI curses declares "bool" as part of the interface. C++ also declares
945 "bool". Neither specifies the size and type of booleans, but both
946 insist on the same name. We chose to accommodate this by making the
947 configure script check for the size and type (e.g., unsigned or signed)
948 that your C++ compiler uses for booleans. If you do not wish to use
949 ncurses with C++, use this option to tell the configure script to not
950 adjust ncurses bool to match C++.
952 --without-cxx-binding
953 Suppress the configure script's check for C++, do not build the
954 C++ binding and related demo.
957 Disable development options. This does not include those that change
958 the interface, such as --enable-widec.
961 Do not use dlsym() to load GPM dynamically.
964 Tell the configure script to suppress the build of ncurses' application
965 programs (e.g., tic). The test applications will still be built if you
966 type "make", though not if you simply do "make install".
969 Tell the configure script to use "xterm-old" for the entry used in
970 the terminfo database. This will work with variations such as
971 X11R5 and X11R6 xterm.
974 COMPATIBILITY WITH OLDER VERSIONS OF NCURSES:
975 --------------------------------------------
977 Because ncurses implements the X/Open Curses Specification, its interface
978 is fairly stable. That does not mean the interface does not change.
979 Changes are made to the documented interfaces when we find differences
980 between ncurses and X/Open or implementations which they certify (such as
981 Solaris). We add extensions to those interfaces to solve problems not
982 addressed by the original curses design, but those must not conflict with
983 the X/Open documentation.
985 Here are some of the major interface changes, and related problems which
986 you may encounter when building a system with different versions of
989 5.6 (December 17, 2006)
992 + generate linkable stubs for some macros:
994 getbegx, getbegy, getcurx, getcury, getmaxx, getmaxy, getparx,
997 and (for libncursesw)
1005 Added internal functions:
1019 Also (if using the hashed database configuration):
1034 Removed internal functions:
1037 Modified internal functions:
1044 5.5 (October 10, 2005)
1047 + terminfo installs "xterm-new" as "xterm" entry rather than
1048 "xterm-old" (aka xterm-r6).
1050 + terminfo data is installed using the tic -x option (few systems
1051 still use ncurses 4.2).
1053 + modify C++ binding to work with newer C++ compilers by providing
1054 initializers and using modern casts. Old-style header names are
1055 still used in this release to allow compiling with not-so-old
1058 + form and menu libraries now work with wide-character data.
1059 Applications which bypassed the form library and manipulated the
1060 FIELD.buf data directly will not work properly with libformw, since
1061 that no longer points to an array of char. The set_field_buffer()
1062 and field_buffer() functions translate to/from the actual field
1065 + change SP->_current_attr to a pointer, adjust ifdef's to ensure that
1066 libtinfo.so and libtinfow.so have the same ABI. The reason for this
1067 is that the corresponding data which belongs to the upper-level
1068 ncurses library has a different size in each model.
1070 + winnstr() now returns multibyte character strings for the
1071 wide-character configuration.
1073 + assume_default_colors() no longer requires that use_default_colors()
1076 + data_ahead() now works with wide-characters.
1078 + slk_set() and slk_wset() now accept and store multibyte or
1079 multicolumn characters.
1081 + start_color() now returns OK if colors have already been started.
1082 start_color() also returns ERR if it cannot allocate memory.
1084 + pair_content() now returns -1 for consistency with init_pair() if it
1085 corresponds to the default-color.
1087 + unctrl() now returns null if its parameter does not correspond
1088 to an unsigned char.
1091 Experimental mouse version 2 supports wheel mice with buttons
1092 4 and 5. This requires ABI 6 because it modifies the encoding
1095 Experimental extended colors allows encoding of 256 foreground
1096 and background colors, e.g., with the xterm-256color or
1097 xterm-88color terminfo entries. This requires ABI 6 because
1098 it changes the size of cchar_t.
1100 Added internal functions:
1104 _nc_retrace_cvoid_ptr
1105 _nc_retrace_void_ptr
1108 Removed internal functions:
1111 Modified internal functions:
1116 5.4 (February 8, 2004)
1119 + add the remaining functions for X/Open curses wide-character support.
1120 These are only available if the library is configured using the
1121 --enable-widec option.
1125 + write getyx() and related 2-return macros in terms of getcury(),
1128 + simplify ifdef for bool declaration in curses.h
1130 + modify ifdef's in curses.h that disabled use of __attribute__() for
1131 g++, since recent versions implement the cases which ncurses uses.
1133 + change some interfaces to use const:
1145 Added internal functions:
1148 _nc_is_charable() wide
1149 _nc_locale_breaks_acs()
1152 _nc_to_widechar() wide
1154 _nc_trace_bufcat() debug
1155 _nc_unicode_locale()
1157 Removed internal functions:
1161 Modified internal functions:
1163 _nc_retrace_chtype()
1165 5.3 (October 12, 2002)
1168 + change type for bool used in headers to NCURSES_BOOL, which usually
1169 is the same as the compiler's definition for 'bool'.
1171 + add all but two functions for X/Open curses wide-character support.
1172 These are only available if the library is configured using the
1173 --enable-widec option. Missing functions are
1177 + add environment variable $NCURSES_ASSUMED_COLORS to modify the
1178 assume_default_colors() extension.
1184 Added internal functions:
1185 _nc_altcharset_name() debug
1187 _nc_retrace_bool() debug
1188 _nc_retrace_unsigned() debug
1190 _nc_trace_ttymode() debug
1195 Removed internal functions:
1198 Modified internal functions:
1201 5.2 (October 21, 2000)
1204 + revert termcap ospeed variable to 'short' (see discussion of the
1205 --with-ospeed configure option).
1210 + made the extended terminal capabilities
1211 (configure --enable-tcap-names) a standard feature. This should
1212 be transparent to applications that do not require it.
1214 + removed the trace() function and related trace support from the
1217 + modified curses.h.in, undef'ing some symbols to avoid conflict
1220 Added extensions: assume_default_colors().
1222 5.0 (October 23, 1999)
1225 + implemented the wcolor_set() and slk_color() functions.
1227 + move macro winch to a function, to hide details of struct ldat
1229 + corrected prototypes for slk_* functions, using chtype rather than
1232 + the slk_attr_{set,off,on} functions need an additional void*
1233 parameter according to XSI.
1235 + modified several prototypes to correspond with 1997 version of X/Open
1236 Curses: [w]attr_get(), [w]attr_set(), border_set() have different
1237 parameters. Some functions were renamed or misspelled:
1238 erase_wchar(), in_wchntr(), mvin_wchntr(). Some developers have used
1241 Added extensions: keybound(), curses_version().
1243 Terminfo database changes:
1245 + change translation for termcap 'rs' to terminfo 'rs2', which is
1246 the documented equivalent, rather than 'rs1'.
1248 The problems are subtler in recent releases.
1250 a) This release provides users with the ability to define their own
1251 terminal capability extensions, like termcap. To accomplish this,
1252 we redesigned the TERMTYPE struct (in term.h). Very few
1253 applications use this struct. They must be recompiled to work with
1256 a) If you use the extended terminfo names (i.e., you used configure
1257 --enable-tcap-names), the resulting terminfo database can have some
1258 entries which are not readable by older versions of ncurses. This
1259 is a bug in the older versions:
1261 + the terminfo database stores booleans, numbers and strings in
1262 arrays. The capabilities that are listed in the arrays are
1263 specified by X/Open. ncurses recognizes a number of obsolete and
1264 extended names which are stored past the end of the specified
1267 + a change to read_entry.c in 951001 made the library do an lseek()
1268 call incorrectly skipping data which is already read from the
1269 string array. This happens when the number of strings in the
1270 terminfo data file is greater than STRCOUNT, the number of
1271 specified and obsolete or extended strings.
1273 + as part of alignment with the X/Open final specification, in the
1274 990109 patch we added two new terminfo capabilities:
1275 set_a_attributes and set_pglen_inch). This makes the indices for
1276 the obsolete and extended capabilities shift up by 2.
1278 + the last two capabilities in the obsolete/extended list are memu
1279 and meml, which are found in most terminfo descriptions for xterm.
1281 When trying to read this terminfo entry, the spurious lseek()
1282 causes the library to attempt to read the final portion of the
1283 terminfo data (the text of the string capabilities) 4 characters
1284 past its starting point, and reads 4 characters too few. The
1285 library rejects the data, and applications are unable to
1286 initialize that terminal type.
1288 FIX: remove memu and meml from the xterm description. They are
1289 obsolete, not used by ncurses. (It appears that the feature was
1290 added to xterm to make it more like hpterm).
1292 This is not a problem if you do not use the -x option of tic to
1293 create a terminfo database with extended names. Note that the
1294 user-defined terminal capabilities are not affected by this bug,
1295 since they are stored in a table after the older terminfo data ends,
1296 and are invisible to the older libraries.
1298 c) Some developers did not wish to use the C++ binding, and used the
1299 configure --without-cxx option. This causes problems if someone
1300 uses the ncurses library from C++ because that configure test
1301 determines the type for C++'s bool and makes ncurses match it, since
1302 both C++ and curses are specified to declare bool. Calling ncurses
1303 functions with the incorrect type for bool will cause execution
1304 errors. In 5.0 we added a configure option "--without-cxx-binding"
1305 which controls whether the binding itself is built and installed.
1310 + correct prototype for termattrs() as per XPG4 version 2.
1312 + add placeholder prototypes for color_set(), erasewchar(),
1313 term_attrs(), wcolor_set() as per XPG4 version 2.
1315 + add macros getcur[xy] getbeg[xy] getpar[xy], which are defined in
1318 New extensions: keyok() and define_key().
1320 Terminfo database changes:
1322 + corrected definition in curses.h for ACS_LANTERN, which was 'I'
1327 We added these extensions: use_default_colors(). Also added
1328 configure option --enable-const, to support the use of const where
1329 X/Open should have, but did not, specify.
1331 The terminfo database content changed the representation of color for
1332 most entries that use ANSI colors. SVr4 curses treats the setaf/setab
1333 and setf/setb capabilities differently, interchanging the red/blue
1334 colors in the latter.
1336 4.0 (December 24, 1996)
1338 We bumped to version 4.0 because the newly released dynamic loader
1339 (ld.so.1.8.5) on Linux did not load shared libraries whose ABI and REL
1340 versions were inconsistent. At that point, ncurses ABI was 3.4 and the
1341 REL was 1.9.9g, so we made them consistent.
1343 1.9.9g (December 1, 1996)
1345 This fixed most of the problems with 1.9.9e, and made these interface
1348 + remove tparam(), which had been provided for compatibility with
1349 some termcap. tparm() is standard, and does not conflict with
1350 application's fallback for missing tparam().
1352 + turn off hardware echo in initscr(). This changes the sense of the
1353 echo() function, which was initialized to echoing rather than
1354 nonechoing (the latter is specified). There were several other
1355 corrections to the terminal I/O settings which cause applications to
1358 + implemented several functions (such as attr_on()) which were
1359 available only as macros.
1361 + corrected several typos in curses.h.in (i.e., the mvXXXX macros).
1363 + corrected prototypes for delay_output(),
1364 has_color, immedok() and idcok().
1366 + corrected misspelled getbkgd(). Some applications used the
1369 + added _yoffset to WINDOW. The size of WINDOW does not impact
1370 applications, since they use only pointers to WINDOW structs.
1372 These changes were made to the terminfo database:
1374 + removed boolean 'getm' which was available as an extended name.
1376 We added these extensions: wresize(), resizeterm(), has_key() and
1379 1.9.9e (March 24, 1996)
1381 not recommended (a last-minute/untested change left the forms and
1382 menus libraries unusable since they do not repaint the screen).
1383 Foreground/background colors are combined incorrectly, working properly
1384 only on a black background. When this was released, the X/Open
1385 specification was available only in draft form.
1387 Some applications (such as lxdialog) were "fixed" to work with the
1388 incorrect color scheme.
1391 IF YOU ARE A SYSTEM INTEGRATOR:
1392 ------------------------------
1394 Configuration and Installation:
1396 On platforms where ncurses is assumed to be installed in /usr/lib,
1397 the configure script uses "/usr" as a default:
1399 Linux, FreeBSD, NetBSD, OpenBSD, Cygwin
1401 For other platforms, the default is "/usr/local". See the discussion
1402 of the "--disable-overwrite" option.
1404 The location of the terminfo is set indirectly by the "--datadir"
1405 configure option, e.g., /usr/share/terminfo, given a datadir of
1406 /usr/share. You may want to override this if you are installing
1407 ncurses libraries in nonstandard locations, but wish to share the
1410 Normally the ncurses library is configured in a pure-terminfo mode;
1411 that is, with the --disable-termcap option. This makes the ncurses
1412 library smaller and faster. The ncurses library includes a termcap
1413 emulation that queries the terminfo database, so even applications that
1414 use raw termcap to query terminal characteristics will win (providing
1415 you recompile and relink them!).
1417 If you must configure with termcap fallback enabled, you may also wish
1418 to use the --enable-getcap option. This speeds up termcap-based
1419 startups, at the expense of not allowing personal termcap entries to
1420 reference the terminfo tree. See comments in
1421 ncurses/tinfo/read_termcap.c for further details.
1423 Note that if you have $TERMCAP set, ncurses will use that value
1424 to locate termcap data. In particular, running from xterm will
1425 set $TERMCAP to the contents of the xterm's termcap entry.
1426 If ncurses sees that, it will not examine /etc/termcap.
1430 The terminfo file assumes that Shift-Tab generates \E[Z (the ECMA-48
1431 reverse-tabulation sequence) rather than ^I. Here are the loadkeys -d
1432 mappings that will set this up:
1434 keycode 15 = Tab Tab
1435 alt keycode 15 = Meta_Tab
1436 shift keycode 15 = F26
1437 string F26 ="\033[Z"
1439 Naming the Console Terminal
1441 In various systems there has been a practice of designating the system
1442 console driver type as `console'. Please do not do this! It
1443 complicates peoples' lives, because it can mean that several different
1444 terminfo entries from different operating systems all logically want to
1445 be called `console'.
1447 Please pick a name unique to your console driver and set that up
1448 in the /etc/inittab table or local equivalent. Send the entry to the
1449 terminfo maintainer (listed in the misc/terminfo file) to be included
1450 in the terminfo file, if it's not already there. See the
1451 term(7) manual page included with this distribution for more on
1452 conventions for choosing type names.
1454 Here are some recommended primary console names:
1456 linux -- Linux console driver
1461 If you are responsible for integrating ncurses for one of these
1462 distribution, please either use the recommended name or get back
1463 to us explaining why you don't want to, so we can work out nomenclature
1464 that will make users' lives easier rather than harder.
1467 RECENT XTERM VERSIONS:
1468 ---------------------
1470 The terminfo database file included with this distribution assumes you
1471 are running a modern xterm based on XFree86 (i.e., xterm-new). The
1472 earlier X11R6 entry (xterm-r6) and X11R5 entry (xterm-r5) is provided
1473 as well. See the --without-xterm-new configure script option if you
1474 are unable to update your system.
1477 CONFIGURING FALLBACK ENTRIES:
1478 ----------------------------
1480 In order to support operation of ncurses programs before the terminfo
1481 tree is accessible (that is, in single-user mode or at OS installation
1482 time) the ncurses library can be compiled to include an array of
1483 pre-fetched fallback entries. This must be done on a machine which
1484 has ncurses' infocmp and terminfo database installed.
1486 These entries are checked by setupterm() only when the conventional
1487 fetches from the terminfo tree and the termcap fallback (if configured)
1488 have been tried and failed. Thus, the presence of a fallback will not
1489 shadow modifications to the on-disk entry for the same type, when that
1490 entry is accessible.
1492 By default, there are no entries on the fallback list. After you have
1493 built the ncurses suite for the first time, you can change the list
1494 (the process needs infocmp(1)). To do so, use the script
1495 ncurses/tinfo/MKfallback.sh. A configure script option
1496 --with-fallbacks does this (it accepts a comma-separated list of the
1497 names you wish, and does not require a rebuild).
1499 If you wanted (say) to have linux, vt100, and xterm fallbacks, you
1500 would use the commands
1503 tinfo/MKfallback.sh linux vt100 xterm >fallback.c
1505 Then just rebuild and reinstall the library as you would normally.
1506 You can restore the default empty fallback list with
1508 tinfo/MKfallback.sh >fallback.c
1510 The overhead for an empty fallback list is one trivial stub function.
1511 Any non-empty fallback list is const-ed and therefore lives in sharable
1512 text space. You can look at the comment trailing each initializer in
1513 the generated ncurses/fallback.c file to see the core cost of the
1514 fallbacks. A good rule of thumb for modern vt100-like entries is that
1515 each one will cost about 2.5K of text space.
1518 BSD CONVERSION NOTES:
1519 --------------------
1521 If you need to support really ancient BSD programs, you probably
1522 want to configure with the --enable-bsdpad option. What this does
1523 is enable code in tputs() that recognizes a numeric prefix on a
1524 capability as a request for that much trailing padding in milliseconds.
1525 There are old BSD programs that do things like tputs("50").
1527 (If you are distributing ncurses as a support-library component of
1528 an application you probably want to put the remainder of this section
1529 in the package README file.)
1531 The following note applies only if you have configured ncurses with
1534 ------------------------------- CUT HERE --------------------------------
1536 If you are installing this application privately (either because you
1537 have no root access or want to experiment with it before doing a root
1538 installation), there are a couple of details you need to be aware of.
1539 They have to do with the ncurses library, which uses terminfo rather
1540 than termcap for describing terminal characteristics.
1542 Though the ncurses library is terminfo-based, it will interpret your
1543 TERMCAP variable (if present), any local termcap files you reference
1544 through it, and the system termcap file. However, in order to avoid
1545 slowing down your application startup, it will only do this once per
1548 The first time you load a given terminal type from your termcap
1549 database, the library initialization code will automatically write it
1550 in terminfo format to a subdirectory under $HOME/.terminfo. After
1551 that, the initialization code will find it there and do a (much
1552 faster) terminfo fetch.
1554 Usually, all this means is that your home directory will silently grow
1555 an invisible .terminfo subdirectory which will get filled in with
1556 terminfo descriptions of terminal types as you invoke them. If anyone
1557 ever installs a global terminfo tree on your system, this will quietly
1558 stop happening and your $HOME/.terminfo will become redundant.
1560 The objective of all this logic is to make converting from BSD termcap
1561 as painless as possible without slowing down your application (termcap
1562 compilation is expensive).
1564 If you don't have a TERMCAP variable or custom personal termcap file,
1565 you can skip the rest of this dissertation.
1567 If you *do* have a TERMCAP variable and/or a custom personal termcap file
1568 that defines a terminal type, that definition will stop being visible
1569 to this application after the first time you run it, because it will
1570 instead see the terminfo entry that it wrote to $HOME/terminfo the
1573 Subsequently, editing the TERMCAP variable or personal TERMCAP file
1574 will have no effect unless you explicitly remove the terminfo entry
1575 under $HOME/terminfo. If you do that, the entry will be recompiled
1576 from your termcap resources the next time it is invoked.
1578 To avoid these complications, use infocmp(1) and tic(1) to edit the
1579 terminfo directory directly.
1581 ------------------------------- CUT HERE --------------------------------
1583 USING NCURSES WITH AFS:
1584 AFS treats each directory as a separate logical filesystem, you
1585 can't hard-link across them. The --enable-symlinks option copes
1586 with this by making tic use symbolic links.
1588 USING NCURSES WITH GPM:
1589 Ncurses 4.1 and up can be configured to use GPM (General Purpose
1590 Mouse) which is used on Linux console. Be aware that GPM is commonly
1591 installed as a shared library which contains a wrapper for the curses
1592 wgetch() function (libcurses.o). Some integrators have simplified
1593 linking applications by combining all or part of libcurses.so into the
1594 libgpm.so file, producing symbol conflicts with ncurses (specifically
1595 the wgetch function). This was originally the BSD curses, but
1596 generally whatever curses library exists on the system.
1598 You may be able to work around this problem by linking as follows:
1600 cc -o foo foo.o -lncurses -lgpm -lncurses
1602 but the linker may not cooperate, producing mysterious errors.
1603 See the FAQ, as well as the discussion under the --with-gpm option:
1605 http://invisible-island.net/ncurses/ncurses.faq.html#using_gpm_lib
1607 BUILDING NCURSES WITH A CROSS-COMPILER
1608 Ncurses can be built with a cross-compiler. Some parts must be built
1609 with the host's compiler since they are used for building programs
1610 (e.g., ncurses/make_hash and ncurses/make_keys) that generate tables
1611 that are compiled into the ncurses library. The essential thing to do
1612 is set the BUILD_CC environment variable to your host's compiler, and
1613 run the configure script configuring for the cross-compiler.
1615 The configure options --with-build-cc, etc., are provided to make this
1616 simpler. Since make_hash and make_keys use only ANSI C features, it
1617 is normally not necessary to provide the other options such as
1618 --with-build-libs, but they are provided for completeness.
1620 Note that all of the generated source-files which are part of ncurses
1621 will be made if you use
1625 This would be useful in porting to an environment which has little
1626 support for the tools used to generate the sources, e.g., sed, awk and
1629 When ncurses has been successfully cross-compiled, you may want to use
1630 "make install" (with a suitable target directory) to construct an
1631 install tree. Note that in this case (as with the --with-fallbacks
1632 option), ncurses uses the development platform's tic to do the
1633 "make install.data" portion.
