REQUIREMENTS:
------------
The --prefix option to configure changes the root directory for installing
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.
+ for systems where ncurses is normally installed as a system library (see
+ "IF YOU ARE A SYSTEM INTEGRATOR"). Use --prefix=/usr to replace your
+ default curses distribution.
The package gets installed beneath the --prefix directory as follows:
In $(prefix)/bin: tic, infocmp, captoinfo, tset,
- reset, clear, tput, toe
+ reset, clear, tput, toe, tabs
In $(prefix)/lib: libncurses*.* libcurses.a
In $(prefix)/share/terminfo: compiled terminal descriptions
In $(prefix)/include: C header files
Do not use commands such as
- make install prefix=XXX
+ 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
+ make install DESTDIR=XXX
See also the discussion of --with-install-prefix.
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

+ various systems 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).
./configure --with-shared --without-normal --without-debug
Rules for generating shared libraries are highly dependent upon the choice

If you have libtool installed, you can type
--disable-largefile
Disable compiler flags needed to use large-file interfaces.
+ --disable-libtool-version
+ when using --with-libtool, control how the major/minor version numbers

+ The default uses the -version-number feature of libtool, which makes
+ the library names compatible (though not identical) with the standard
+ build using --with-shared.
+
+ Use --disable-libtool-version to use the libtool -version-info feature.
+ This corresponds to the setting used before patch 20100515.

--disable-leaks
For testing, compile-in code that frees memory that normally would not
be freed, to simplify analysis of memory-leaks.
application. These are (for example $TERMINFO) those that allow the
search path for the terminfo or termcap entry to be customized.
+ --disable-rpath-hack
+ Normally the configure script helps link libraries found in unusual
+ places by adding an rpath option to the link command. If you are
+ building packages, this feature may be redundant. Use this option
+ to suppress the feature.
+
--disable-scroll-hints
Compile without scroll-hints code. This option is ignored when
hashmap scrolling is configured, which is the default.
+ --disable-tic-depends
+ When building shared libraries, normally the tic library is linked to
+ depend upon the ncurses library (or equivalently, on the tinfo-library
+ if the --with-termlib option was given). The tic- and tinfo-library
+ ABIs do not depend on the --enable-widec option. Some packagers have
+ used this to reduce the number of library files which are packaged by
+ using only one copy of those libraries. To make this work properly,
+ the tic library must be built without an explicit dependency on the
+ underlying library (ncurses vs ncursesw, tinfo vs tinfow). Use this
+ configure option to do that.
+ For example
+ configure --with-ticlib --with-shared --disable-tic-depends
+
--disable-tparm-varargs
Portable programs should call tparm() using the fixed-length parameter
list documented in X/Open. ncurses provides varargs support for this

of tabs.
+ --enable-interop
+ Compile-in experimental interop bindings. These provide generic types
+ for the form-library.
+
--enable-mixed-case
Controls whether the filesystem on which the terminfo database resides
supports mixed-case filenames (normal for UNIX, but not on other
terminfo entries. This is the default, unless you have disabled the
extended functions.
+ --enable-pc-files
+ If pkg-config is found (see --with-pkg-config), generate ".pc" files

+
--enable-reentrant
Compile experimental configuration which improves reentrant use of the
library by reducing global and static variables. This option is also
is not strictly compatible. This option allows one to implement this
alteration without patching the source code.
+ --enable-sp-funcs
+ Compile-in support for extended functions which accept a SCREEN pointer,
+ reducing the need for juggling the global SP value with set_term() and
+ delscreen().
+
+ --enable-string-hacks
+ Controls whether strlcat and strlcpy may be used. The same issue
+ applies to OpenBSD's warnings about snprintf, noting that this function
+ is weakly standardized.
+
+ Aside from stifling these warnings, there is no functional improvement
+ in ncurses.
+
--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
capabilities as user-defined strings. This option is the default,
unless you have disabled the extended functions.
+ --enable-term-driver
+ Enable experimental terminal-driver. This is currently used for the
+ MinGW port, by providing a way to substitute the low-level terminfo
+ library with different terminal drivers.
+
--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.
+ Termcap support requires run-time parsing rather than loading
+ predigested data. If you have specified --with-ticlib, then you
+ cannot have termcap support since run-time parsing is done in the
+ tic library, which is intentionally not part of normal linkage
+ dependencies.
+
--enable-warnings
Turn on GCC compiler warnings. There should be only a few.
--with-ada-objects=DIR
Tell where to install the Ada objects (default: PREFIX/lib/ada/adalib)
+ --with-ada-sharedlib
+ Build a shared library for Ada95 binding, if the compiler permits.
+
+ NOTE: You must also set the --with-shared option on some platforms
+ for a successful build. You need not use this option when you set
+ --with-shared, unless you want to use the Ada shared library.
+
--with-bool=TYPE
If --without-cxx is specified, override the type used for the "bool"

correspond with that in <stdbool.h>, or defaults to platform-specific
sizes).
+ --with-build-cpp=XXX

+
--with-chtype=TYPE
Override type of chtype, which stores the video attributes and (if

+ functionally identical with the originals.
+
+ In addition to the "_sp" functions, there are a few new functions
+ associated with this feature: ceiling_panel, ground_panel,
+ new_prescr.
+
+ If the library is not built with the sp-funcs extension, there

+
+ 5.7 (November 2, 2008)
+ Interface changes:
+
+ + generate linkable stubs for some macros:
+ getattrs
+
+ + Add new library configuration for tic-library (the non-curses portion
+ of the ncurses library used for the tic program as well as some
+ others such as tack. There is no API change, but makefiles would be
+ changed to use the tic-library built separately.
+
+ tack, distributed separately from ncurses, uses some of the internal
+ _nc_XXX functions, which are declared in the tic.h header file.
+
+ The reason for providing this separate library is that none of the
+ functions in it are suitable for threaded applications.
+
+ + Add new library configuration (ncursest, ncurseswt) which provides
+ rudimentary support for POSIX threads. This introduces opaque
+ access functions to the WINDOW structure and adds a parameter to
+ several internal functions.
+
+ + move most internal variables (except tic-library) into data blocks
+ _nc_globals and _nc_prescreen to simplify analysis. Those were
+ globally accessible, but since they were not part of the documented
+ API, there is no ABI change.
+
+ + changed static tables of strings to be indices into long strings, to
+ improve startup performance. This changes parameter lists for some
+ of the internal functions.
+
+ Added extensions:
+
+ + add NCURSES_OPAQUE definition in curses.h to control whether internal
+ details of the WINDOW structure are visible to an application. This
+ is always defined when the threaded library is built, and is optional
+ otherwise. New functions for this: is_cleared, is_idcok, is_idlok,
+ is_immedok, is_keypad, is_leaveok, is_nodelay, is_notimeout,
+ is_scrollok, is_syncok, wgetparent and wgetscrreg.
+
+ + the threaded library (ncursest) also disallows direct updating of
+ global curses-level variables, providing functions (via macros) for
+ obtaining their value. A few of those variables can be modified by
+ the application, using new functions: set_escdelay, set_tabsize
+
+ + added functions use_window() and use_screen() which wrap a mutex
+ (if threading is configured) around a call to a user-supplied
+ function.
+
+ Added internal functions:
+ _nc_get_alias_table
+ _nc_get_screensize
+ _nc_keyname
+ _nc_screen_of
+ _nc_set_no_padding
+ _nc_tracechar
+ _nc_tracemouse
+ _nc_unctrl
+ _nc_ungetch
+
+ These are used for leak-testing, and are stubs for
+ ABI compatibility when ncurses is not configured for that
+ using the --disable-leaks configure script option:
+
+ _nc_free_and_exit
+ _nc_leaks_tinfo
+
+ Removed internal functions:
+ none
+
+ Modified internal functions:
+ _nc_fifo_dump
+ _nc_find_entry
+ _nc_handle_sigwinch
+ _nc_init_keytry
+ _nc_keypad
+ _nc_locale_breaks_acs
+ _nc_timed_wait
