ncurses 库 可能有用酒用 没用就算了 我觉得还可以用

	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 	

    --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-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.

    --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".

    --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:

    5.5 (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.

	+ simplify ifdef for bool declaration in curses.h

	+ modify ifdef's in curses.h that disabled use of __attribute__() for
	  g++, since recent versions implement the cases which ncurses uses.

	+ change some interfaces to use const:
		define_key()
		mvprintw()
		mvwprintw()
		printw()
		vw_printw()
		winsnstr()
		wprintw()

	Added extensions:
		key_defined()

	Added internal functions:
		_nc_get_locale()
		_nc_insert_ch()
		_nc_is_charable()	wide
		_nc_locale_breaks_acs()
		_nc_pathlast()
		_nc_to_char()		wide
		_nc_to_widechar()	wide
		_nc_tparm_analyze()
		_nc_trace_bufcat()	debug
		_nc_unicode_locale()

	Removed internal functions:
		_nc_outstr()
		_nc_sigaction()

	Modified internal functions:
		_nc_remove_string()
		_nc_retrace_chtype()

    5.3 (October 12, 2002)
	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_reset_colors()
		_nc_retrace_bool()	debug
		_nc_retrace_unsigned()	debug
		_nc_rootname()
		_nc_trace_ttymode()	debug
		_nc_varargs()		debug
		_nc_visbufn()		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
