- 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, where
-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 section titled IF YOU ARE A SYSTEM INTEGRATOR
-below.
-
-If you are converting from BSD curses and do not have root access, be sure
-to read the BSD CONVERSION NOTES section below.
-
-If you are using a version of XFree86 xterm older than 3.1.2F, see the section
-on RECENT XTERM VERSIONS below.
-
-If you are trying to build GNU Emacs using ncurses for terminal support,
-read the USING NCURSES WITH EMACS section below.
-
-If you are trying to build applications using gpm with ncurses,
-read the USING NCURSES WITH GPM section below.
-
-If you are running over the Andrew File System see the note below on
-USING NCURSES WITH AFS.
-
-If you are cross-compiling, see the note below on BUILDING NCURSES WITH A
-CROSS-COMPILER.
-
-If you want to build the Ada95 binding, go to the Ada95 directory and
-follow the instructions there. The Ada95 binding is not covered below.
-
-If you are using anything but (a) Linux, or (b) one of the 4.4BSD-based
-i386 Unixes, go read the Portability section in the TO-DO file before you
-do anything else.
-
-
-REQUIREMENTS:
-------------
-
-You will need the following in order to build and install ncurses under UNIX:
-
- * ANSI C compiler (gcc, for instance)
- * sh (bash will do)
- * awk (mawk or gawk will do)
- * sed
- * BSD or System V style install (a script is enclosed)
-
-Ncurses has been also built in the OS/2 EMX environment.
-
-
-INSTALLATION PROCEDURE:
-----------------------
-
-1. First, decide whether you want ncurses to replace your existing library (in
- which case you'll need super-user privileges) or be installed in parallel
- with it.
-
- The --prefix option to configure changes the root directory for installing
- ncurses. The default is in subdirectories of /usr/local. Use
- --prefix=/usr to replace your default curses distribution. This is the
- default for Linux and BSD/OS users.
-
- The package gets installed beneath the --prefix directory as follows:
-
- In $(prefix)/bin: tic, infocmp, captoinfo, tset,
- reset, clear, tput, toe
- In $(prefix)/lib: libncurses*.* libcurses.a
- In $(prefix)/share/terminfo: compiled terminal descriptions
- In $(prefix)/include: C header files
- Under $(prefix)/man: the manual pages
-
- Note however that the configure script attempts to locate previous
- installation of ncurses, and will set the default prefix according to where
- it finds the ncurses headers.
-
-2. Type `./configure' in the top-level directory of the distribution to
- configure ncurses for your operating system and create the Makefiles.
- Besides --prefix, various configuration options are available to customize
- the installation; use `./configure --help' to list the available options.
-
- 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)
-
- libcurses.a (normal, a link to libncurses.a)
- This gets left out if you configure with --disable-overwrite.
-
- libncurses.so (shared)
-
- libncurses_g.a (debug)
-
- libncurses_p.a (profile)
-
- libncurses.la (libtool)
-
- If you configure using the --enable-widec option, a "w" is appended to the
- library names (e.g., libncursesw.a), and the resulting libraries support
- wide-characters, e.g., via a UTF-8 locale. The corresponding header files
- are compatible with the non-wide-character configuration; wide-character
- features are provided by ifdef's in the header files. The wide-character
- library interfaces are not binary-compatible with the non-wide-character
- version. Building and running the wide-character code relies on a fairly
- recent implementation of libiconv. We have built this configuration on
- Linux using libiconv, sometimes requiring libutf8.
-
- If you do not specify any models, the normal and debug libraries will be
- configured. Typing `configure' with no arguments is equivalent to:
-
- ./configure --with-normal --with-debug --enable-overwrite
-
- Typing
-
- ./configure --with-shared
-
- makes the shared libraries the default, resulting in
-
- ./configure --with-shared --with-normal --with-debug --enable-overwrite
-
- If you want only shared libraries, type
-
- ./configure --with-shared --without-normal --without-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 libtool installed, you can type
-
- ./configure --with-libtool
-
- to generate the appropriate static and/or shared libraries for your
- platform using libtool.
-
- You can make curses and terminfo fall back to an existing file of termcap
- definitions by configuring with --enable-termcap. If you do this, the
- library will search /etc/termcap before the terminfo database, and will
- also interpret the contents of the TERM environment variable. See the
- section BSD CONVERSION NOTES below.
-
-3. Type `make'. Ignore any warnings, no error messages should be produced.
- This should compile the ncurses library, the terminfo compiler tic(1),
- captoinfo(1), infocmp(1), toe(1), clear(1) tset(1), reset(1), and tput(1)
- programs (see the manual pages for explanation of what they do), some test
- programs, and the panels, menus, and forms libraries.
-
-4. Run ncurses and several other test programs in the test directory to
- verify that ncurses functions correctly before doing an install that
- may overwrite system files. Read the file test/README for details on
- the test programs.
-
- NOTE: You must have installed the terminfo database, or set the
- environment variable $TERMINFO to point to a SVr4-compatible terminfo
- database before running the test programs. Not all vendors' terminfo
- databases are SVr4-compatible, but most seem to be. Exceptions include
- DEC's Digital Unix (formerly known as OSF/1).
-
- It is possible to configure ncurses to use other terminfo database formats.
- A few are provided as examples in the include-directory (see --with-caps).
-
- 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.
-
-5. Once you've tested, you can type `make install' to install libraries,
- the programs, the terminfo database and the manual 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, etc...
- 'make install.includes' installs the headers.
- 'make install.libs' installs the libraries (and the headers).
- 'make install.data' installs the terminfo data. (Note: `tic' must
- be installed before the terminfo data can be
- compiled).
- 'make install.man' installs the manual 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. #
- ############################################################################
-
- The terminfo(5) manual page must 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 manual page
- to be sure. You may also install the manual pages after preprocessing
- with tbl(1) by specifying the configure option --with-manpage-tbl.
-
- If the system already has a curses library that you need to keep using
- you'll need to distinguish between it and ncurses. See the discussion of
- --disable-overwrite. 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 have another 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.
-
- 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.
-
- See the BSD CONVERSION NOTES section below for a few more details.
-
-6. The c++ directory has C++ classes that are built on top of ncurses and
- panels. You must have c++ (and its libraries) installed before you can
- compile and run the demo.
-
- Use --without-cxx-binding to tell configure to not build the C++ bindings
- and demo.
-
- If you do not have C++, you must use the --without-cxx option to tell
- the configure script to not attempt to determine the type of 'bool'
- which may be supported by C++. IF YOU USE THIS OPTION, BE ADVISED THAT
- YOU MAY NOT BE ABLE TO COMPILE (OR RUN) NCURSES APPLICATIONS WITH C++.
-
-
-SUMMARY OF CONFIGURE OPTIONS:
-----------------------------
-
- The configure script provides a short list of its options when you type
-
- ./configure --help
-
- The --help and several options are common to all configure scripts that are
- generated with autoconf. Those are all listed before the line
-
- --enable and --with options recognized:
-
- The other options are specific to this package. We list them in alphabetic
- order.
-
- --disable-assumed-color
- With ncurses 5.1, we introduced a new function, assume_default_colors()
- which allows applications to specify what the default foreground and
- background color are assumed to be. Most color applications use
- full-screen color; but a few do not color the background. While the
- assumed values can be overridden by invoking assume_default_colors(),
- you may find it useful to set the assumed values to the pre-5.1
- convention, using this configure option.
-
- --disable-big-core
- Assume machine has little memory. The configure script attempts to
- determine if your machine has enough memory (about 6Mb) to compile the
- terminfo database without writing portions to disk. Some allocators
- return deceptive results, so you may have to override the configure
- script. Or you may be building tic for a smaller machine.
-
- --disable-database
- Use only built-in data. The ncurses libraries normally read terminfo
- and termcap data from disk. You can configure ncurses to have a
- built-in database, aka "fallback" entries. Embedded applications may
- have no need for an external database. Some, but not all of the
- programs are useful in this configuration, e.g., reset and tput versus
- infocmp and tic.
-
- --disable-ext-funcs
- Disable function-extensions. Configure ncurses without the functions
- that are not specified by XSI. See ncurses/modules for the exact
- list of library modules that would be suppressed.
-
- --disable-hashmap
- Compile without hashmap scrolling-optimization code. This algorithm is
- the default.
-
- --disable-leaks
- For testing, compile-in code that frees memory that normally would not
- be freed, to simplify analysis of memory-leaks.
-
- --disable-macros
- For testing, use functions rather than macros. The program will run
- more slowly, but it is simpler to debug. This makes a header file
- "nomacros.h". See also the --enable-expanded option.
-
- --disable-overwrite
- If you are installing ncurses on a system which contains another
- development version of curses, or which could be confused by the loader
- for another version, we recommend that you leave out the link to
- -lcurses. The ncurses library is always available as -lncurses.
- Disabling overwrite also causes the ncurses header files to be
- installed into a subdirectory, e.g., /usr/local/include/ncurses,
- rather than the include directory. This makes it simpler to avoid
- compile-time conflicts with other versions of curses.h
-
- --disable-root-environ
- Compile with environment restriction, so certain environment variables
- are not available when running as root, or via a setuid/setgid
- application. These are (for example $TERMINFO) those that allow the
- search path for the terminfo or termcap entry to be customized.
-
- --disable-scroll-hints
- Compile without scroll-hints code. This option is ignored when
- hashmap scrolling is configured, which is the default.
-
- --enable-add-ons=DIR...
- This is used to check if this package is a glibc add-on. This is used
- only by the glibc makefiles.
-
- --enable-assertions
- For testing, compile-in assertion code. This is used only for a few
- places where ncurses cannot easily recover by returning an error code.
-
- --enable-broken_linker
- A few platforms have what we consider a broken linker: it cannot link
- objects from an archive solely by referring to data objects in those
- files, but requires a function reference. This configure option
- changes several data references to functions to work around this
- problem.
-
- NOTE: With ncurses 5.1, this may not be necessary, since we are
- told that some linkers interpret uninitialized global data as a
- different type of reference which behaves as described above. We have
- explicitly initialized all of the global data to work around the
- problem.
-
- --enable-bsdpad
- Recognize BSD-style prefix padding. Some ancient BSD programs (such as
- nethack) call tputs("50") to implement delays.
-
- --enable-colorfgbg
- Compile with experimental $COLORFGBG code. That environment variable
- is set by some terminal emulators as a hint to applications, by
- advertising the default foreground and background colors. During
- initialization, ncurses sets color pair 0 to match this.
-
- --enable-const
- The curses interface as documented in XSI is rather old, in fact
- including features that precede ANSI C. The prototypes generally do
- not make effective use of "const". When using stricter compilers (or
- gcc with appropriate warnings), you may see warnings about the mismatch
- between const and non-const data. We provide a configure option which
- changes the interfaces to use const - quieting these warnings and
- reflecting the actual use of the parameters more closely. The ncurses
- library uses the symbol NCURSES_CONST for these instances of const,
- and if you have asked for compiler warnings, will add gcc's const-qual
- warning. There will still be warnings due to subtle inconsistencies
- in the interface, but at a lower level.
-
- NOTE: configuring ncurses with this option may detract from the
- portability of your applications by encouraging you to use const in
- places where the XSI curses interface would not allow them. Similar
- issues arise when porting to SVr4 curses, which uses const in even
- fewer places.
-
- --enable-echo
- Use the option --disable-echo to make the build-log less verbose by
- suppressing the display of the compile and link commands. This makes
- it easier to see the compiler warnings. (You can always use "make -n"
- to see the options that are used).
-
- --enable-expanded
- For testing, generate functions for certain macros to make them visible
- as such to the debugger. See also the --disable-macros option.
-
- --enable-getcap
- Use the 4.4BSD getcap code if available, or a bundled version of it to
- fetch termcap entries. Entries read in this way cannot use (make
- cross-references to) the terminfo tree, but it is faster than reading
- /etc/termcap.
-
- --enable-getcap-cache
- Cache translated termcaps under the directory $HOME/.terminfo
-
- NOTE: this sounds good - it makes ncurses run faster the second time.
- But look where the data comes from - an /etc/termcap containing lots of
- entries that are not up to date. If you configure with this option and
- forget to install the terminfo database before running an ncurses
- application, you will end up with a hidden terminfo database that
- generally does not support color and will miss some function keys.
-
- --enable-hard-tabs
- Compile-in cursor-optimization code that uses hard-tabs. We would make
- this a standard feature except for the concern that the terminfo entry
- may not be accurate, or that your stty settings have disabled the use
- of tabs.
-
- --enable-no-padding
- Compile-in support for the $NCURSES_NO_PADDING environment variable,
- which allows you to suppress the effect of non-mandatory padding in
- terminfo entries. This is the default, unless you have disabled the
- extended functions.
-
- --enable-rpath
- Use rpath option when generating shared libraries, and with some
- restrictions when linking the corresponding programs. This applies
- mainly to systems using the GNU linker (read the manpage).
-
- --enable-safe-sprintf
- Compile with experimental safe-sprintf code. You may consider using
- this if you are building ncurses for a system that has neither
- vsnprintf() or vsprintf(). It is slow, however.
-
- --enable-sigwinch
- Compile support for ncurses' SIGWINCH handler. If your application has
- its own SIGWINCH handler, ncurses will not use its own. The ncurses
- handler causes wgetch() to return KEY_RESIZE when the screen-size
- changes. This option is the default, unless you have disabled the
- extended functions.
-
- --enable-symlinks
- If your system supports symbolic links, make tic use symbolic links
- rather than hard links to save diskspace when writing aliases in the
- terminfo database.
-
- --enable-tcap-names
- Compile-in support for user-definable terminal capabilities. Use the
- -x option of tic and infocmp to treat unrecognized terminal
- capabilities as user-defined strings. This option is the default,
- unless you have disabled the extended functions.
-
- --enable-termcap
- Compile in support for reading terminal descriptions from termcap if no
- match is found in the terminfo database. See also the --enable-getcap
- and --enable-getcap-cache options.
-
- --enable-warnings
- Turn on GCC compiler warnings. There should be only a few.
-
- --enable-widec
- Compile with experimental wide-character code. This makes a different
- version of the libraries (e.g., libncursesw.so), which stores
- characters as wide-characters,
-
- NOTE: applications compiled with this configuration are not compatible
- with those built for 8-bit characters. You cannot simply make a
- symbolic link to equate libncurses.so with libncursesw.so
-
- NOTE: the Ada95 binding may be built against either version of the the
- ncurses library, but you must decide which: the binding installs the
- same set of files for either version. Currently (2002/6/22) it does
- not use the extended features from the wide-character code, so it is
- probably better to not install the binding for that configuration.
-
- --enable-xmc-glitch
- Compile-in support experimental xmc (magic cookie) code.
-
- --with-ada-compiler=CMD
- Specify the Ada95 compiler command (default "gnatmake")
-
- --with-ada-include=DIR
- Tell where to install the Ada includes (default:
- PREFIX/lib/ada/adainclude)
-
- --with-ada-objects=DIR
- Tell where to install the Ada objects (default: PREFIX/lib/ada/adalib)
-
- --with-bool=TYPE
- If --without-cxx is specified, override the type used for the "bool"
- declared in curses.h (normally the type is automatically chosen to
- correspond with that in <stdbool.h>, or defaults to platform-specific
- sizes).
-
- --with-build-cc=XXX
- If cross-compiling, specify a host C compiler, which is needed to
- compile a few utilties which generate source modules for ncurses.
- If you do not give this option, the configure script checks if the
- $BUILD_CC variable is set, and otherwise defaults to gcc or cc.
-
- --with-build-cflags=XXX
- If cross-compiling, specify the host C compiler-flags. You might need
- to do this if the target compiler has unusual flags which confuse the
- host compiler.
-
- --with-build-cppflags=XXX
- If cross-compiling, specify the host C preprocesor-flags. You might
- need to do this if the target compiler has unusual flags which confuse
- the host compiler.
-
- --with-build-ldflags=XXX
- If cross-compiling, specify the host linker-flags. You might need to
- do this if the target linker has unusual flags which confuse the host
- compiler.
-
- --with-build-libs=XXX
- If cross-compiling, the host libraries. You might need to do this if
- the target environment requires unusual libraries.
-
- --with-caps=XXX
- Specify an alternate terminfo capabilities file, which makes the
- configure script look for "include/Caps.XXX". A few systems, e.g.,
- AIX 4.x use the same overall file-format as ncurses for terminfo
- data, but use different alignments within the tables to support
- legacy applications. For those systems, you can configure ncurses
- to use a terminfo database which is compatible with the native
- applications.
-
- --with-database=XXX
- Specify the terminfo source file to install. Usually you will wish
- to install ncurses' default (misc/terminfo.src). Certain systems
- have special requirements, e.g, OS/2 EMX has a customized terminfo
- source file.
-
- --with-dbmalloc
- For testing, compile and link with Conor Cahill's dbmalloc library.
-
- --with-debug
- Generate debug-libraries (default). These are named by adding "_g"
- to the root, e.g., libncurses_g.a
-
- --with-default-terminfo-dir=XXX
- Specify the default terminfo database directory. This is normally
- DATADIR/terminfo, e.g., /usr/share/terminfo.
-
- --with-develop
- Enable experimental/development options. This does not count those
- that change the interface, such as --enable-widec.
-
- --with-dmalloc
- For testing, compile and link with Gray Watson's dmalloc library.
-
- --with-fallbacks=XXX
- Specify a list of fallback terminal descriptions which will be
- compiled into the ncurses library. See CONFIGURING FALLBACK ENTRIES.
-
- --with-gpm
- use Alessandro Rubini's GPM library to provide mouse support on the
- Linux console.
-
- --with-install-prefix=XXX
- Allows you to specify an alternate location for installing ncurses
- after building it. The value you specify is prepended to the "real"
- install location. This simplifies making binary packages.
-
- NOTE: a few systems build shared libraries with fixed pathnames; this
- option probably will not work for those configurations.
-
- --with-libtool
- Generate libraries with libtool. If this option is selected, then
- it overrides all other library model specifications.
-
- --with-manpage-format=XXX
- Tell the configure script how you would like to install man-pages. The
- option value must be one of these: gzip, compress, BSDI, normal,
- formatted. If you do not give this option, the configure script
- attempts to determine which is the case.
-
- --with-manpage-renames=XXX
- Tell the configure script that you wish to rename the manpages while
- installing. Currently the only distribution which does this is
- the Linux Debian. The option value specifies the name of a file
- that lists the renamed files, e.g., $srcdir/man/man_db.renames
-
- --with-manpage-symlinks
- Tell the configure script that you wish to make symbolic links in the
- man-directory for aliases to the man-pages. This is the default, but
- can be disabled for systems that provide this automatically. Doing
- this on systems that do not support symbolic links will result in
- copying the man-page for each alias.
-
- --with-manpage-tbl
- Tell the configure script that you with to preprocess the manpages
- by running them through tbl to generate tables understandable by
- nroff.
-
- --with-ospeed=TYPE
- Override type of ospeed variable, which is part of the termcap
- compatibility interface. In termcap, this is a 'short', which works
- for a wide range of baudrates because ospeed is not the actual speed
- but the encoded value, e.g., B9600 would be a small number such as 13.
- However the encoding scheme originally allowed for values "only" up to
- 38400bd. A newer set of definitions past 38400bd is not encoded as
- compactly, and is not guaranteed to fit into a short (see the function
- cfgetospeed(), which returns a speed_t for this reason). In practice,
- applications that required knowledge of the ospeed variable, i.e.,
- those using termcap, do not use the higher speeds. Your application
- (or system, in general) may or may not.
-
- --with-normal
- Generate normal (i.e., static) libraries (default).
-
- --with-profile
- Generate profile-libraries These are named by adding "_p" to the root,
- e.g., libncurses_p.a
-
- --with-rcs-ids
- Compile-in RCS identifiers. Most of the C files have an identifier.
-
- --with-shared
- Generate shared-libraries. The names given depend on the system for
- which you are building, typically using a ".so" suffix, along with
- symbolic links that refer to the release version.
-
- NOTE: Unless you override the configure script by setting the $CFLAGS
- environment variable, these will not be built with the -g debugging
- option.
-
- --with-shlib-version=XXX
- Specify whether to use the release or ABI version for shared libraries.
- This is normally chosen automatically based on the type of system
- which you are building on. We use it for testing the configure script.
-
- --with-system-type=XXX
- For testing, override the derived host system-type which is used to
- decide things such as the linker commands used to build shared
- libraries. This is normally chosen automatically based on the type of
- system which you are building on. We use it for testing the configure
- script.
-
- --with-terminfo-dirs=XXX
- Specify a search-list of terminfo directories which will be compiled
- into the ncurses library (default: DATADIR/terminfo)
-
- --with-termlib
- When building the ncurses library, organize this as two parts: the
- curses library (libncurses) and the low-level terminfo library
- (libtinfo). This is done to accommodate applications that use only
- the latter. The terminfo library is about half the size of the total.
-
- --with-termpath=XXX
- Specify a search-list of termcap files which will be compiled into the
- ncurses library (default: /etc/termcap:/usr/share/misc/termcap)
-
- --without-ada
- Suppress the configure script's check for Ada95, do not build the
- Ada95 binding and related demo.
-
- --without-curses-h
- Don't install the ncurses header with the name "curses.h". Rather,
- install as "ncurses.h" and modify the installed headers and manpages
- accordingly.
-
- --without-cxx
- XSI curses declares "bool" as part of the interface. C++ also declares
- "bool". Neither specifies the size and type of booleans, but both
- insist on the same name. We chose to accommodate this by making the
- configure script check for the size and type (e.g., unsigned or signed)
- that your C++ compiler uses for booleans. If you do not wish to use
- ncurses with C++, use this option to tell the configure script to not
- adjust ncurses bool to match C++.
-
- --without-cxx-binding
- Suppress the configure script's check for C++, do not build the
- C++ binding and related demo.
-
- --without-progs
- Tell the configure script to suppress the build of ncurses' application
- programs (e.g., tic). The test applications will still be built if you
- type "make", though not if you simply do "make install".
-
-
-COMPATIBILITY WITH OLDER VERSIONS OF NCURSES:
---------------------------------------------
-
- Because ncurses implements the X/Open Curses Specification, its interface
- is fairly stable. That does not mean the interface does not change.
- Changes are made to the documented interfaces when we find differences
- between ncurses and X/Open or implementations which they certify (such as
- Solaris). We add extensions to those interfaces to solve problems not
- addressed by the original curses design, but those must not conflict with
- the X/Open documentation.
-
- Here are some of the major interface changes, and related problems which
- you may encounter when building a system with different versions of
- ncurses:
-
- 5.3 (pre-release)
- Interface changes:
-
- + change type for bool used in headers to NCURSES_BOOL, which usually
- is the same as the compiler's definition for 'bool'.
-
- + add all but two functions for X/Open curses wide-character support.
- These are only available if the library is configured using the
- --enable-widec option. Missing functions are
- pecho_wchar()
- slk_wset()
-
- + add environment variable $NCURSES_ASSUMED_COLORS to modify the
- assume_default_colors() extension.
-
- Added extensions:
- is_term_resized()
- resize_term()
- Added internal functions:
- _nc_altcharset_name() debug
- _nc_rootname()
- _nc_trace_ttymode() debug
- _nc_varargs() debug
- _nc_wgetch()
- Removed internal functions:
- _nc_background()
- Modified internal functions:
- _nc_freeall() debug
-
- 5.2 (October 21, 2000)
- Interface changes:
-
- + revert termcap ospeed variable to 'short' (see discussion of the
- --with-ospeed configure option).
-
- 5.1 (July 8, 2000)
- Interface changes:
-
- + made the extended terminal capabilities
- (configure --enable-tcap-names) a standard feature. This should
- be transparent to applications that do not require it.
-
- + removed the trace() function and related trace support from the
- production library.
-
- + modified curses.h.in, undef'ing some symbols to avoid conflict
- with C++ STL.
-
- Added extensions: assume_default_colors().
-
- 5.0 (October 23, 1999)
- Interface changes:
-
- + implemented the wcolor_set() and slk_color() functions.
-
- + move macro winch to a function, to hide details of struct ldat
-
- + corrected prototypes for slk_* functions, using chtype rather than
- attr_t.
-
- + the slk_attr_{set,off,on} functions need an additional void*
- parameter according to XSI.
-
- + modified several prototypes to correspond with 1997 version of X/Open
- Curses: [w]attr_get(), [w]attr_set(), border_set() have different
- parameters. Some functions were renamed or misspelled:
- erase_wchar(), in_wchntr(), mvin_wchntr(). Some developers have used
- attr_get().
-
- Added extensions: keybound(), curses_version().
-
- Terminfo database changes:
-
- + change translation for termcap 'rs' to terminfo 'rs2', which is
- the documented equivalent, rather than 'rs1'.
-
- The problems are subtler in recent releases.
-
- a) This release provides users with the ability to define their own
- terminal capability extensions, like termcap. To accomplish this,
- we redesigned the TERMTYPE struct (in term.h). Very few
- applications use this struct. They must be recompiled to work with
- the 5.0 library.
-
- a) If you use the extended terminfo names (i.e., you used configure
- --enable-tcap-names), the resulting terminfo database can have some
- entries which are not readable by older versions of ncurses. This
- is a bug in the older versions:
-
- + the terminfo database stores booleans, numbers and strings in
- arrays. The capabilities that are listed in the arrays are
- specified by X/Open. ncurses recognizes a number of obsolete and
- extended names which are stored past the end of the specified
- entries.
-
- + a change to read_entry.c in 951001 made the library do an lseek()
- call incorrectly skipping data which is already read from the
- string array. This happens when the number of strings in the
- terminfo data file is greater than STRCOUNT, the number of
- specified and obsolete or extended strings.
-
- + as part of alignment with the X/Open final specification, in the
- 990109 patch we added two new terminfo capabilities:
- set_a_attributes and set_pglen_inch). This makes the indices for
- the obsolete and extended capabilities shift up by 2.
-
- + the last two capabilities in the obsolete/extended list are memu
- and meml, which are found in most terminfo descriptions for xterm.
-
- When trying to read this terminfo entry, the spurious lseek()
- causes the library to attempt to read the final portion of the
- terminfo data (the text of the string capabilities) 4 characters
- past its starting point, and reads 4 characters too few. The
- library rejects the data, and applications are unable to
- initialize that terminal type.
-
- FIX: remove memu and meml from the xterm description. They are
- obsolete, not used by ncurses. (It appears that the feature was
- added to xterm to make it more like hpterm).
-
- This is not a problem if you do not use the -x option of tic to
- create a terminfo database with extended names. Note that the
- user-defined terminal capabilities are not affected by this bug,
- since they are stored in a table after the older terminfo data ends,
- and are invisible to the older libraries.
-
- c) Some developers did not wish to use the C++ binding, and used the
- configure --without-cxx option. This causes problems if someone
- uses the ncurses library from C++ because that configure test
- determines the type for C++'s bool and makes ncurses match it, since
- both C++ and curses are specified to declare bool. Calling ncurses
- functions with the incorrect type for bool will cause execution
- errors. In 5.0 we added a configure option "--without-cxx-binding"
- which controls whether the binding itself is built and installed.
-
- 4.2 (March 2, 1998)
- Interface changes:
-
- + correct prototype for termattrs() as per XPG4 version 2.
-
- + add placeholder prototypes for color_set(), erasewchar(),
- term_attrs(), wcolor_set() as per XPG4 version 2.
-
- + add macros getcur[xy] getbeg[xy] getpar[xy], which are defined in
- SVr4 headers.
-
- New extensions: keyok() and define_key().
-
- Terminfo database changes:
-
- + corrected definition in curses.h for ACS_LANTERN, which was 'I'
- rather than 'i'.
-
- 4.1 (May 15, 1997)
-
- We added these extensions: use_default_colors(). Also added
- configure option --enable-const, to support the use of const where
- X/Open should have, but did not, specify.
-
- The terminfo database content changed the representation of color for
- most entries that use ANSI colors. SVr4 curses treats the setaf/setab
- and setf/setb capabilities differently, interchanging the red/blue
- colors in the latter.
-
- 4.0 (December 24, 1996)
-
- We bumped to version 4.0 because the newly released dynamic loader
- (ld.so.1.8.5) on Linux did not load shared libraries whose ABI and REL
- versions were inconsistent. At that point, ncurses ABI was 3.4 and the
- REL was 1.9.9g, so we made them consistent.
-
- 1.9.9g (December 1, 1996)
-
- This fixed most of the problems with 1.9.9e, and made these interface
- changes:
-
- + remove tparam(), which had been provided for compatibility with
- some termcap. tparm() is standard, and does not conflict with
- application's fallback for missing tparam().
-
- + turn off hardware echo in initscr(). This changes the sense of the
- echo() function, which was initialized to echoing rather than
- nonechoing (the latter is specified). There were several other
- corrections to the terminal I/O settings which cause applications to
- behave differently.
-
- + implemented several functions (such as attr_on()) which were
- available only as macros.
-
- + corrected several typos in curses.h.in (i.e., the mvXXXX macros).
-
- + corrected prototypes for delay_output(),
- has_color, immedok() and idcok().
-
- + corrected misspelled getbkgd(). Some applications used the
- misspelled name.
-
- + added _yoffset to WINDOW. The size of WINDOW does not impact
- applications, since they use only pointers to WINDOW structs.
-
- These changes were made to the terminfo database:
-
- + removed boolean 'getm' which was available as an extended name.
-
- We added these extensions: wresize(), resizeterm(), has_key() and
- mcprint().
-
- 1.9.9e (March 24, 1996)
-
- not recommended (a last-minute/untested change left the forms and
- menus libraries unusable since they do not repaint the screen).
- Foreground/background colors are combined incorrectly, working properly
- only on a black background. When this was released, the X/Open
- specification was available only in draft form.
-
- Some applications (such as lxdialog) were "fixed" to work with the
- incorrect color scheme.
-
-
-IF YOU ARE A SYSTEM INTEGRATOR:
-------------------------------
-
- Beginning with 1.9.9, the ncurses distribution includes both a tset
- utility and /usr/share/tabset directory. If you are installing ncurses,
- it is no longer either necessary or desirable to install tset-jv.
-
- Configuration and Installation:
-
- 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/share/terminfo; you may want to override this with
- --datadir=/usr/share/misc; terminfo and tabset are installed under the
- data directory.
-
- Please configure the ncurses library in a pure-terminfo mode; that
- is, with the --disable-termcap option. This will make the ncurses
- 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!).
-
- If you must configure with termcap fallback enabled, you may also
- wish to use the --enable-getcap option. This option speeds up
- termcap-based startups, at the expense of not allowing personal
- termcap entries to reference the terminfo tree. See the code in
- ncurses/tinfo/read_termcap.c for details.
-
- Note that if you have $TERMCAP set, ncurses will use that value
- to locate termcap data. In particular, running from xterm will
- set $TERMCAP to the contents of the xterm's termcap entry.
- If ncurses sees that, it will not examine /etc/termcap.
-
- Keyboard Mapping:
-
- The terminfo file assumes that Shift-Tab generates \E[Z (the ECMA-48
- reverse-tabulation sequence) rather than ^I. Here are the loadkeys -d
- mappings that will set this up:
-
- keycode 15 = Tab Tab
- alt keycode 15 = Meta_Tab
- shift keycode 15 = F26
- string F26 ="\033[Z"
-
- Naming the Console Terminal
-
- 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 file, 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 some recommended primary console names:
-
- 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.
-
-
-RECENT XTERM VERSIONS:
----------------------
-
- The terminfo database file included with this distribution assumes you
- are running an XFree86 xterm based on X11R6 (i.e., xterm-r6). The
- earlier X11R5 entry (xterm-r5) is provided as well.
-
- If you are running XFree86 version 3.2 (actually 3.1.2F and up), you
- should consider using the xterm-xf86-v32 (or later, the most recent
- version is always named "xterm-xfree86") entry, which adds ANSI color
- and the VT220 capabilities which have been added in XFree86. If you
- are running a mixed network, however, where this terminal description
- may be used on an older xterm, you may have problems, since
- applications that assume these capabilities will produce incorrect
- output on the older xterm (e.g., highlighting is not cleared).
-
-
-CONFIGURING FALLBACK ENTRIES:
-----------------------------
-
- In order to support operation of ncurses programs before the terminfo
- tree is accessible (that is, in single-user mode or at OS installation
- time) the ncurses library can be compiled to include an array of
- pre-fetched fallback entries.
-
- These entries are checked by setupterm() only when the conventional
- fetches from the terminfo tree and the termcap fallback (if configured)
- have been tried and failed. Thus, the presence of a fallback will not
- shadow modifications to the on-disk entry for the same type, when that
- entry is accessible.
-
- By default, there are no entries on the fallback list. After you
- have built the ncurses suite for the first time, you can change
- the list (the process needs infocmp(1)). To do so, use the script
- MKfallback.sh. A configure script option --with-fallbacks does this
- (it accepts a comma-separated list of the names you wish, and does
- not require a rebuild).
-
- If you wanted (say) to have linux, vt100, and xterm fallbacks, you
- would use the commands
-
- cd ncurses;
- MKfallback.sh linux vt100 xterm >fallback.c
-
- Then just rebuild and reinstall the library as you would normally.
- You can restore the default empty fallback list with
-
- MKfallback.sh >fallback.c
-
- The overhead for an empty fallback list is one trivial stub function.
- Any non-empty fallback list is const-ed and therefore lives in sharable
- text space. You can look at the comment trailing each initializer in
- the generated ncurses/fallback.c file to see the core cost of the
- fallbacks. A good rule of thumb for modern vt100-like entries is that
- each one will cost about 2.5K of text space.
-
-
-BSD CONVERSION NOTES:
---------------------
-
- If you need to support really ancient BSD programs, you probably
- want to configure with the --enable-bsdpad option. What this does
- is enable code in tputs() that recognizes a numeric prefix on a
- capability as a request for that much trailing padding in milliseconds.
- There are old BSD programs that do things like tputs("50").
-
- (If you are distributing ncurses as a support-library component of
- an application you probably want to put the remainder of this section
- in the package README file.)
-
- The following note applies only if you have configured ncurses with
- --enable-termcap.
-
-------------------------------- CUT HERE --------------------------------
-
-If you are installing this application privately (either because you
-have no root access or want to experiment with it before doing a root
-installation), there are a couple of details you need to be aware of.
-They have to do with the ncurses library, which uses terminfo rather
-than termcap for describing terminal characteristics.
-
-Though the ncurses library is terminfo-based, it will interpret your
-TERMCAP variable (if present), any local termcap files you reference
-through it, and the system termcap file. However, in order to avoid
-slowing down your application startup, it will only do this once per
-terminal type!
-
-The first time you load a given terminal type from your termcap
-database, the library initialization code will automatically write it
-in terminfo format to a subdirectory under $HOME/.terminfo. After
-that, the initialization code will find it there and do a (much
-faster) terminfo fetch.
-
-Usually, all this means is that your home directory will silently grow
-an invisible .terminfo subdirectory which will get filled in with
-terminfo descriptions of terminal types as you invoke them. If anyone
-ever installs a global terminfo tree on your system, this will quietly
-stop happening and your $HOME/.terminfo will become redundant.
-
-The objective of all this logic is to make converting from BSD termcap
-as painless as possible without slowing down your application (termcap
-compilation is expensive).
-
-If you don't have a TERMCAP variable or custom personal termcap file,
-you can skip the rest of this dissertation.
-
-If you *do* have a TERMCAP variable and/or a custom personal termcap file
-that defines a terminal type, that definition will stop being visible
-to this application after the first time you run it, because it will
-instead see the terminfo entry that it wrote to $HOME/terminfo the
-first time around.
-
-Subsequently, editing the TERMCAP variable or personal TERMCAP file
-will have no effect unless you explicitly remove the terminfo entry
-under $HOME/terminfo. If you do that, the entry will be recompiled
-from your termcap resources the next time it is invoked.
-
-To avoid these complications, use infocmp(1) and tic(1) to edit the
-terminfo directory directly.
-
-------------------------------- CUT HERE --------------------------------
-
-USING NCURSES WITH AFS:
- AFS treats each directory as a separate logical filesystem, you
- can't hard-link across them. The --enable-symlinks option copes
- with this by making tic use symbolic links.
-
-USING NCURSES WITH EMACS:
- GNU Emacs has its own termcap support. By default, it uses a mixture
- of those functions and code linked from the host system's libraries.
- You need to foil this and shut out the GNU termcap library entirely.
-
- In order to do this, hack the Linux config file (s/linux.h) to contain
- a #define TERMINFO and set the symbol LIBS_TERMCAP to "-lncurses".
-
- We have submitted such a change for the 19.30 release, so it may
- already be applied in your sources -- check for the #define TERMINFO.
-
-USING NCURSES WITH GPM:
- Ncurses 4.1 and up can be configured to use GPM (General Purpose Mouse)
- which is used on Linux console. Be aware that GPM is commonly
- installed as a shared library which contains a wrapper for the curses
- wgetch() function (libcurses.o). Some integrators have simplified
- linking applications by combining all or part of libcurses.so (the BSD
- curses) into the libgpm.so file, producing symbol conflicts with
- ncurses (specifically the wgetch function). You may be able to work
- around this problem by linking as follows:
-
- cc -o foo foo.o -lncurses -lgpm -lncurses
-
- but the linker may not cooperate, producing mysterious errors.
- A patched version of gpm is available:
-
- dickey.his.com:/ncurses/gpm-1.10-970125.tar.gz
-
- This patch is incorporated in gpm 1.12; however some integrators
- are slow to update this library. Current distributions of gpm can
- be configured properly using the --without-curses option.
-
-BUILDING NCURSES WITH A CROSS-COMPILER
- Ncurses can be built with a cross-compiler. Some parts must be built
- with the host's compiler since they are used for building programs
- (e.g., ncurses/make_hash and ncurses/make_keys) that generate tables
- that are compiled into the ncurses library. You should set the
- BUILD_CC environment variable to your host's compiler, and run the
- configure script configuring for the cross-compiler.
-
- Note that all of the generated source-files which are part of ncurses
- will be made if you use
-
- make sources
-
- This would be useful in porting to an environment which has little
- support for the tools used to generate the sources, e.g., sed, awk and
- Bourne-shell.
