How to install Ncurses/Terminfo on your system
---------------------------------------------------------------------
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.
REQUIREMENTS:
------------
-You will need the following in order to build and install ncurses under UNIX:
+You will need the following to build and install ncurses under UNIX:
* ANSI C compiler (gcc, for instance)
* sh (bash will do)
with it.

- --prefix=/usr to replace your default curses distribution. This is the
- default for Linux and BSD/OS users.
+ ncurses. The default is normally in subdirectories of /usr/local, except
+ for systems where ncurses is normally installed as a system library, e.g.,
+ Linux, the various BSD systems and Cygwin. Use --prefix=/usr to replace
+ your default curses distribution.
The package gets installed beneath the --prefix directory as follows:
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.
+ Note 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.
+
+ Do not use commands such as
+
+ make install prefix=XXX
+
+ to change the prefix after configuration, since the prefix value is used
+ for some absolute pathnames such as TERMINFO. Instead do this
+
+ make install DESTDIR=XXX
+
+ See also the discussion of --with-install-prefix.
2. Type `./configure' in the top-level directory of the distribution to
configure ncurses for your operating system and create the Makefiles.
recent implementation of libiconv. We have built this configuration on
Linux using libiconv, sometimes requiring libutf8.
+ If you configure using the --with-pthread option, a "t" is appended to
+ the library names (e.g., libncursest.a, libncursestw.a).
+
If you do not specify any models, the normal and debug libraries will be
configured. Typing `configure' with no arguments is equivalent to:
return deceptive results, so you may have to override the configure
script. Or you may be building tic for a smaller machine.
+ --disable-big-strings
+ Disable compile-time optimization of predefined tables which puts
+ all of their strings into a very long string, to reduce relocation
+ overhead.
+
--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
more likely writable than the system terminfo database. Use this
option to disable the feature altogether.
+ --disable-largefile
+ Disable compiler flags needed to use large-file interfaces.
+
--disable-leaks
For testing, compile-in code that frees memory that normally would not
be freed, to simplify analysis of memory-leaks.
+ Any implementation of curses must not free the memory associated with
+ a screen, since (even after calling endwin()), it must be available
+ for use in the next call to refresh(). There are also chunks of
+ memory held for performance reasons. That makes it hard to analyze
+ curses applications for memory leaks. To work around this, build
+ a debugging version of the ncurses library which frees those chunks
+ which it can, and provides the _nc_free_and_exit() function to free
+ the remainder on exit. The ncurses utility and test programs use this
+ feature, e.g., via the ExitProgram() macro.
+
+ --disable-lp64
+ The header files will ignore use of the _LP64 symbol to make chtype
+ and mmask_t types 32 bits (they may be long on 64-bit hosts, for
+ compatibility with older releases).
+
+ NOTE: this is potentially an ABI change, depending on existing
+ packages. The default for this option is "disabled" for ncurses
+ ABI 5, and "enabled" for ABI 6.
+
--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.
+ more slowly, but it is simpler to debug. This defines NCURSES_NOMACROS
+ at build time. See also the --enable-expanded option.
--disable-overwrite
If you are installing ncurses on a system which contains another
rather than the include directory. This makes it simpler to avoid
compile-time conflicts with other versions of curses.h
+ --disable-relink
+ If --enable-rpath is given, the generated makefiles normally will
+ rebuild the libraries during install. Use this option to simply
+ copy whatever the linked produced.
+
+ This option is ignored if --enable-rpath is not given.
+
--disable-root-environ
Compile with environment restriction, so certain environment variables
are not available when running as root, or via a setuid/setgid
Compile without scroll-hints code. This option is ignored when
hashmap scrolling is configured, which is the default.
+ --disable-tparm-varargs
+ Portable programs should call tparm() using the fixed-length parameter
+ list documented in X/Open. ncurses provides varargs support for this
+ function. Use --disable-tparm-varargs to disable this support.
+
--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.
For testing, generate functions for certain macros to make them visible
as such to the debugger. See also the --disable-macros option.
+ --enable-ext-colors
+ Extend the cchar_t structure to allow more than 16 colors to be
+ encoded. This applies only to the wide-character (--enable-widec)
+ configuration.
+
+ NOTE: using this option will make libraries which are not binary-
+ compatible with libncursesw 5.4. None of the interfaces change, but
+ applications which have an array of cchar_t's must be recompiled.
+
+ --enable-ext-mouse
+ Modify the encoding of mouse state to make room for a 5th mouse button.
+ That allows one to use ncurses with a wheel mouse with xterm or
+ similar X terminal emulators.
+
+ NOTE: using this option will make libraries which are not binary-
+ compatible with libncursesw 5.4. None of the interfaces change, but
+ applications which have mouse mask mmask_t's must be recompiled.
+
--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.
+ If configured for one of the *BSD systems, this automatically uses
+ the hashed database system produced using cap_mkdb or similar tools.
+ In that case, there is no advantage in using the --enable-getcap-cache
+ option.
+
+ See also the --with-hashed-db option.
+
--enable-getcap-cache
Cache translated termcaps under the directory $HOME/.terminfo
- NOTE: this sounds good - it makes ncurses run faster the second time.
+ 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
may not be accurate, or that your stty settings have disabled the use
of tabs.
+ --enable-mixed-case
+ Controls whether the filesystem on which the terminfo database resides
+ supports mixed-case filenames (normal for UNIX, but not on other
+ systems). If you do not specify this option, the configure script
+ checks the current filesystem.
+
--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-reentrant
+ Compile experimental configuration which improves reentrant use of the
+ library by reducing global and static variables. This option is also
+ set if --with-pthread is used.
+
--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).
+ Use rpath option when generating shared libraries, and (with some
+ restrictions) when linking the corresponding programs. This originally
+ (in 1997) applied mainly to systems using the GNU linker (read the
+ manpage).
+
+ More recently it is useful for systems that require special treatment
+ shared libraries in "unusual" locations. The "system" libraries reside
+ in directories which are on the loader's default search-path. While
+ you may be able to use workarounds such as the $LD_LIBRARY_PATH
+ environment variable, they do not work with setuid applications since
+ the LD_LIBRARY_PATH variable would be unset in that situation.
+
+ This option does not apply to --with-libtool, since libtool makes
+ extra assumptions about rpath.
--enable-safe-sprintf
Compile with experimental safe-sprintf code. You may consider using
changes. This option is the default, unless you have disabled the
extended functions.
+ --enable-signed-char
+ The term.h header declares a Booleans[] array typed "char". But it
+ stores signed values there and "char" is not necessarily signed.
+ Some packagers choose to alter the type of Booleans[] though this
+ is not strictly compatible. This option allows one to implement this
+ alteration without patching the source code.
+
--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
--enable-warnings
Turn on GCC compiler warnings. There should be only a few.
+ --enable-wgetch-events
+ Compile with experimental wgetch-events code. See ncurses/README.IZ

+ the GPM library.
+
+ Currently ncurses uses the dlsym() function to bind to the library at
+ runtime, so it is only necessary that the library be present when
+ ncurses is built, to obtain the filename (or soname) used in the
+ corresponding dlopen() call. If you give a value for this option,
+ e.g.,
+
+ --with-gpm=$HOME/tmp/test-gpm.so
+
+ that overrides the configure check for the soname.
+
+ See also --without-dlsym
+
+ --with-hashed-db[=XXX]
+ Use a hashed database for storing terminfo data rather than storing
+ each compiled entry in a separate binary file within a directory
+ tree.
+
+ In particular, this uses the Berkeley database 1.8.5 interface, as
+ provided by that and its successors db 2, 3, and 4. The actual
+ interface is slightly different in the successor versions of the
+ Berkeley database. The database should have been configured using
+ "--enable-compat185".
+
+ If you use this option for configuring ncurses, tic will only be able
+ to write entries in the hashed database. infocmp can still read
+ entries from a directory tree as well as reading entries from the
+ hashed database. To do this, infocmp determines whether the $TERMINFO
+ variable points to a directory or a file, and reads the directory-tree
+ or hashed database respectively.
+
+ You cannot have a directory containing both hashed-database and
+ filesystem-based terminfo entries.
+
+ Use the parameter value to give the install-prefix used for the
+ datbase, e.g.,

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.
+ If an option value is given, that overrides the name of the terminfo
+ library. For instance, if the wide-character version is built, the
+ terminfo library would be named libtinfow. But the libtinfow interface
+ is upward compatible from libtinfo, so it would be possible to overlay
+ libtinfo.so with a "wide" version of libtinfow.so by renaming it with
+ this option.
+
--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)
+ --with-ticlib[=XXX]
+ When building the ncurses library, build a separate library for
+ the modules that are used only by the utility programs. Normally
+ those would be bundled with the termlib or ncurses libraries.
+
+ If an option value is given, that overrides the name of the tic
+ library. As in termlib, there is no ABI difference between the
+ "wide" libticw.so and libtic.so

--with-trace
Configure the trace() function as part of the all models of the ncurses
library. Normally it is part of the debug (libncurses_g) library only.
+ --with-valgrind
+ For testing, compile with debug option.
+ This also sets the --disable-leaks option.
+
--without-ada
Suppress the configure script's check for Ada95, do not build the
Ada95 binding and related demo.
Suppress the configure script's check for C++, do not build the
C++ binding and related demo.
+ --without-develop
+ Disable development options. This does not include those that change
+ the interface, such as --enable-widec.
+
+ --without-dlsym
+ Do not use dlsym() to load GPM dynamically.
+
--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".
+ --without-xterm-new
+ Tell the configure script to use "xterm-old" for the entry used in
+ the terminfo database. This will work with variations such as
+ X11R5 and X11R6 xterm.

COMPATIBILITY WITH OLDER VERSIONS OF NCURSES:
--------------------------------------------
you may encounter when building a system with different versions of
ncurses:

+ "xterm-old" (aka xterm-r6).
+
+ + terminfo data is installed using the tic -x option (few systems

+
+ + modify C++ binding to work with newer C++ compilers by providing

+
+ + form and menu libraries now work with wide-character data.
+ Applications which bypassed the form library and manipulated the
+ FIELD.buf data directly will not work properly with libformw, since
+ that no longer points to an array of char. The set_field_buffer()
+ and field_buffer() functions translate to/from the actual field
+ data.
+
+ + change SP->_current_attr to a pointer, adjust ifdef's to ensure that

+ of mouse events.
+
+ Experimental extended colors allows encoding of 256 foreground

- 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

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
+ tinfo/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
+ tinfo/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
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.

+ 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:
+ linking applications by combining all or part of libcurses.so into the
+ libgpm.so file, producing symbol conflicts with ncurses (specifically
+ the wgetch function). This was originally the BSD curses, but
+ generally whatever curses library exists on the system.
+
+ 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
+ See the FAQ, as well as the discussion under the --with-gpm option:
- 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.
+ that are compiled into the ncurses library. The essential thing to do
+ is set the BUILD_CC environment variable to your host's compiler, and
+ run the configure script configuring for the cross-compiler.
+
+ The configure options --with-build-cc, etc., are provided to make this
+ simpler. Since make_hash and make_keys use only ANSI C features, it
+ is normally not necessary to provide the other options such as
+ --with-build-libs, but they are provided for completeness.
Note that all of the generated source-files which are part of ncurses
will be made if you use
support for the tools used to generate the sources, e.g., sed, awk and
Bourne-shell.
+ When ncurses has been successfully cross-compiled, you may want to use
+ "make install" (with a suitable target directory) to construct an
+ install tree. Note that in this case (as with the --with-fallbacks
+ option), ncurses uses the development platform's tic to do the
+ "make install.data" portion.
