+ 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-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
+ 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-home-terminfo
+ The $HOME/.terminfo directory is normally added to ncurses' search
+ list for reading/writing terminfo entries, since that directory is
+ 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-libtool-version
+ when using --with-libtool, control how the major/minor version numbers
+ are used for constructing the library name.
+
+ 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.
+
+ 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 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
+ 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-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
+ 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
+ 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.
+
+ --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-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.
+ 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-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
+ 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-pc-files
+ If pkg-config is found (see --with-pkg-config), generate ".pc" files
+ for each of the libraries, and install them in pkg-config's library
+ directory.
+
+ --enable-pthreads-eintr
+ add logic in threaded configuration to ensure that a read(2) system
+ call can be interrupted for SIGWINCH.
+
+ --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 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
+ 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-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-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-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-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.
+
+ --enable-weak-symbols
+ If the --with-pthread option is set, check if the compiler supports
+ weak-symbols. If it does, then name the thread-capable library without
+ the "t" (libncurses rather than libncursest), and provide for
+ dynamically loading the pthreads entrypoints at runtime. This allows
+ one to reduce the number of library files for ncurses.
+
+ --enable-wgetch-events
+ Compile with experimental wgetch-events code. See ncurses/README.IZ
+
+ --enable-widec
+ Compile with 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-abi-version=NUM
+ Override the ABI version, which is used in shared library filenames.
+ Normally this is the same as the release version; some ports have
+ special requirements for compatibility.
+
+ This option does not affect linking with libtool, which uses the
+ release major/minor numbers.
+
+ --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-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"
+ 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-cpp=XXX
+ This option is provided by the same macro used for $BUILD_CC, etc.,
+ but is not directly used by ncurses.
+
+ --with-build-cc=XXX
+ If cross-compiling, specify a host C compiler, which is needed to
+ compile a few utilities 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.
+
+ You can also set the environment variable $BUILD_CFLAGS rather than
+ use this option.
+
+ --with-build-cppflags=XXX
+ If cross-compiling, specify the host C preprocessor-flags. You might
+ need to do this if the target compiler has unusual flags which confuse
+ the host compiler.
+
+ You can also set the environment variable $BUILD_CPPFLAGS rather than
+ use this option.
+
+ --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.
+
+ You can also set the environment variable $BUILD_LDFLAGS rather than
+ use this option.
+
+ --with-build-libs=XXX
+ If cross-compiling, the host libraries. You might need to do this if
+ the target environment requires unusual libraries.
+
+ You can also set the environment variable $BUILD_LIBS rather than
+ use this option.
+
+ --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-ccharw-max=XXX
+ Override the size of the wide-character array in cchar_t structures.
+ Changing this will alter the binary interface. This defaults to 5.
+
+ --with-chtype=TYPE
+ Override type of chtype, which stores the video attributes and (if
+ --enable-widec is not given) a character. Prior to ncurses 5.5, this
+ was always unsigned long, but with ncurses 5.5, it may be unsigned.
+ Use this option if you need to preserve compatibility with 64-bit
+ executables, e.g., by setting "--with-chtype=long" (the configure
+ script supplies "unsigned").
+
+ --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.
+ This also sets the --disable-leaks option.
+
+ --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-dmalloc
+ For testing, compile and link with Gray Watson's dmalloc library.
+ This also sets the --disable-leaks option.
+
+ --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. Prior to ncurses 5.5, this introduced a dependency on
+ 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.,
+ --with-hashed-db=/usr/local/BigBase
+ to find the corresponding include- and lib-directories under the
+ given directory.
+
+ See also the --enable-getcap option.
+
+ --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. The
+ makefile variable DESTDIR is set by this option. It is also possible
+ to use
+ make install DESTDIR=XXX
+ since the makefiles pass that variable to subordinate makes.
+
+ NOTE: a few systems build shared libraries with fixed pathnames; this
+ option probably will not work for those configurations.
+
+ --with-libtool[=XXX]
+ Generate libraries with libtool. If this option is selected, then it
+ overrides all other library model specifications. Note that libtool
+ must already be installed, uses makefile rules dependent on GNU make,
+ and does not promise to follow the version numbering convention of
+ other shared libraries on your system. However, if the --with-shared
+ option does not succeed, you may get better results with this option.
+
+ If a parameter value is given, it must be the full pathname of the
+ particular version of libtool, e.g.,
+ /usr/bin/libtool-1.2.3
+
+ It is possible to rebuild the configure script to use the automake
+ macros for libtool, e.g., AC_PROG_LIBTOOL. See the comments in
+ aclocal.m4 for CF_PROG_LIBTOOL, and ensure that you build configure
+ using the appropriate patch for autoconf from
+ http://invisible-island.net/autoconf/
+
+ --with-manpage-aliases
+ Tell the configure script you wish to create entries in the
+ man-directory for aliases to manpages which list them, e.g., the
+ functions in the panel manpage. This is the default. You can disable
+ it if your man program does this. You can also disable
+ --with-manpage-symlinks to install files containing a ".so" command
+ rather than symbolic links.
+
+ --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 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-mmask-t=TYPE
+ Override type of mmask_t, which stores the mouse mask. Prior to
+ ncurses 5.5, this was always unsigned long, but with ncurses 5.5, it
+ may be unsigned. Use this option if you need to preserve compatibility
+ with 64-bit executables.
+
+ --with-normal
+ Generate normal (i.e., static) libraries (default).
+
+ Note: on Linux, the configure script will attempt to use the GPM
+ library via the dlsym() function call. Use --without-dlsym to disable
+ this feature, or --without-gpm, depending on whether you wish to use
+ GPM.
+
+ --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-pkg-config=[DIR]
+ Check for pkg-config, optionally specifying its path.
+
+ --with-pkg-config-libdir=[DIR]
+ If pkg-config was found, override the automatic check for its library
+ path.
+
+ --with-profile
+ Generate profile-libraries These are named by adding "_p" to the root,
+ e.g., libncurses_p.a
+
+ --with-pthread
+ Link with POSIX threads, set --enable-reentrant. The use_window() and
+ use_screen() functions will use mutex's, allowing rudimentary support
+ for multithreaded applications.
+
+ --with-rcs-ids
+ Compile-in RCS identifiers. Most of the C files have an identifier.
+
+ --with-rel-version=NUM
+ Override the release version, which may be used in shared library
+ filenames. This consists of a major and minor version number separated
+ by ".". Normally the major version number is the same as the ABI
+ version; some ports have special requirements for compatibility.
+
+ --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.
+
+ NOTE: For some configurations, e.g., installing a new version of
+ ncurses shared libraries on a machine which already has ncurses
+ shared libraries, you may encounter problems with the linker.
+ For example, it may prevent you from running the build tree's
+ copy of tic (for installing the terminfo database) because it
+ loads the system's copy of the ncurses shared libraries. In that
+ case, using the misc/shlib script may be helpful, since it sets
+ $LD_LIBRARY_PATH to point to the build tree, e.g.,
+ ./misc/shlib make install
+
+ NOTE: If you use the --with-ada-sharedlib option, you should also
+ set this option, to ensure that C-language modules needed for the
+ Ada binding use appropriate compiler options.
+
+ --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-sysmouse
+ use FreeBSD sysmouse interface provide mouse support on the console.
+
+ --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[=XXX]
+ 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
+
+ NOTE: Overriding the name of the tic library may be useful if you are
+ also using the --with-termlib option to rename libtinfo. If you are
+ not doing that, renaming the tic library can result in conflicting
+ library dependencies for tic and other programs built with the tic
+ library.
+
+ --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.
+
+ --with-wrap-prefix=XXX
+ When using the --enable-reentrant option, ncurses redefines variables
+ that would be global in curses, e.g., LINES, as a macro that calls a
+ "wrapping" function which fetches the data from the current SCREEN
+ structure. Normally that function is named by prepending "_nc_" to the
+ variable's name. The function is technically private (since portable
+ applications would not refer directly to it). But according to one
+ line of reasoning, it is not the same type of "private" as functions
+ which applications should not call even via a macro. This configure
+ option lets you choose the prefix for these wrapped variables.
+
+ --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.
+
+ Likewise, do not install an alias "curses" for the ncurses manpage.
+
+ --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-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-manpages
+ Tell the configure script to suppress the install of ncurses' manpages.
+
+ --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-tests
+ Tell the configure script to suppress the build of ncurses' test
+ programs.
+
+ --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:
+--------------------------------------------
+
+ 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:
+
+ 5.8 (Feb 26, 2011)
+ Interface changes:
+
+ + add an alternate library configuration, i.e., "terminal driver" to
+ support port to Windows, built with MinGW. There are two drivers
+ (terminfo and Windows console). The terminfo driver works on other
+ platforms.
+
+ + add a new set of functions which accept a SCREEN* parameter, in
+ contrast with the original set which use the global value "sp".
+ By default, these names end with "_sp", and are otherwise
+ 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
+ are no related interface changes.
+
+ + add tiparm function based on review of X/Open Curses Issue 7.
+
+ + change internal _nc_has_mouse function to public has_mouse function
+
+ Added extensions:
+
+ + add a few more functions to support the NCURSES_OPAQUE feature:
+ get_escdelay, is_pad, is_subwin
+
+ Added internal functions (other than "_sp" variants):
+ _nc_curscr_of
+ _nc_format_slks
+ _nc_get_alias_table
+ _nc_get_hash_info
+ _nc_insert_wch
+ _nc_newscr_of
+ _nc_outc_wrapper
+ _nc_retrace_char
+ _nc_retrace_int_attr_t
+ _nc_retrace_mmask_t
+ _nc_setup_tinfo
+ _nc_stdscr_of
+ _nc_tinfo_cmdch
+
+ Removed internal functions:
+ _nc_makenew (some configurations replace by _nc_makenew_sp)
+
+ Modified internal functions:
+ _nc_UpdateAttrs
+ _nc_get_hash_table
+ _nc_has_mouse
+ _nc_insert_ch
+ _nc_wgetch
+
+ 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
+ _nc_update_screensize
+
+ Use new typedef TRIES to replace "struct tries":
+
+ _nc_add_to_try
+ _nc_expand_try
+ _nc_remove_key
+ _nc_remove_string
+ _nc_trace_tries
+
+ 5.6 (December 17, 2006)
+ Interface changes:
+
+ + generate linkable stubs for some macros:
+
+ getbegx, getbegy, getcurx, getcury, getmaxx, getmaxy, getparx,
+ getpary, getpary,
+
+ and (for libncursesw)
+
+ wgetbkgrnd
+
+ Added extensions:
+ nofilter()
+ use_legacy_coding()
+
+ Added internal functions:
+ _nc_first_db
+ _nc_get_source
+ _nc_handle_sigwinch
+ _nc_is_abs_path
+ _nc_is_dir_path
+ _nc_is_file_path
+ _nc_keep_tic_dir
+ _nc_keep_tic_dir
+ _nc_last_db
+ _nc_next_db
+ _nc_read_termtype
+ _nc_tic_dir
+
+ Also (if using the hashed database configuration):
+
+ _nc_db_close
+ _nc_db_first
+ _nc_db_get
+ _nc_db_have_data
+ _nc_db_have_index
+ _nc_db_next
+ _nc_db_open
+ _nc_db_put
+
+ otherwise
+
+ _nc_hashed_db
+
+ Removed internal functions:
+ none
+
+ Modified internal functions:
+ _nc_add_to_try
+ _nc_do_color
+ _nc_expand_try
+ _nc_remove_key
+ _nc_setupscreen
+
+ 5.5 (October 10, 2005)
+ Interface changes:
+
+ + terminfo installs "xterm-new" as "xterm" entry rather than
+ "xterm-old" (aka xterm-r6).
+
+ + terminfo data is installed using the tic -x option (few systems
+ still use ncurses 4.2).
+
+ + modify C++ binding to work with newer C++ compilers by providing
+ initializers and using modern casts. Old-style header names are
+ still used in this release to allow compiling with not-so-old
+ compilers.
+
+ + 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
+ libtinfo.so and libtinfow.so have the same ABI. The reason for this
+ is that the corresponding data which belongs to the upper-level
+ ncurses library has a different size in each model.
+
+ + winnstr() now returns multibyte character strings for the
+ wide-character configuration.
+
+ + assume_default_colors() no longer requires that use_default_colors()
+ be called first.
+
+ + data_ahead() now works with wide-characters.
+
+ + slk_set() and slk_wset() now accept and store multibyte or
+ multicolumn characters.
+
+ + start_color() now returns OK if colors have already been started.
+ start_color() also returns ERR if it cannot allocate memory.
+
+ + pair_content() now returns -1 for consistency with init_pair() if it
+ corresponds to the default-color.
+
+ + unctrl() now returns null if its parameter does not correspond
+ to an unsigned char.
+
+ Added extensions:
+ Experimental mouse version 2 supports wheel mice with buttons
+ 4 and 5. This requires ABI 6 because it modifies the encoding
+ of mouse events.
+
+ Experimental extended colors allows encoding of 256 foreground
+ and background colors, e.g., with the xterm-256color or
+ xterm-88color terminfo entries. This requires ABI 6 because
+ it changes the size of cchar_t.
+
+ Added internal functions:
+ _nc_check_termtype2
+ _nc_resolve_uses2
+ _nc_retrace_cptr
+ _nc_retrace_cvoid_ptr
+ _nc_retrace_void_ptr
+ _nc_setup_term
+
+ Removed internal functions:
+ none
+
+ Modified internal functions:
+ _nc_insert_ch
+ _nc_save_str
+ _nc_trans_string
+
+ 5.4 (February 8, 2004)
+ Interface changes:
+
+ + add the remaining functions for X/Open curses wide-character support.
+ These are only available if the library is configured using the
+ --enable-widec option.
+ pecho_wchar()
+ slk_wset()
+
+ + write getyx() and related 2-return macros in terms of getcury(),
+ getcurx(), etc.
