# SYNOPSIS
|
||
|
|
#
|
||
|
|
# AX_WITH_CURSES
|
||
|
|
#
|
||
|
|
# DESCRIPTION
|
||
|
|
#
|
||
|
|
# This macro checks whether a SysV or X/Open-compatible Curses library is
|
||
|
|
# present, along with the associated header file. The NcursesW
|
||
|
|
# (wide-character) library is searched for first, followed by Ncurses,
|
||
|
|
# then the system-default plain Curses. The first library found is the
|
||
|
|
# one returned.
|
||
|
|
#
|
||
|
|
# The following options are understood: --with-ncursesw, --with-ncurses,
|
||
|
|
# --without-ncursesw, --without-ncurses. The "--with" options force the
|
||
|
|
# macro to use that particular library, terminating with an error if not
|
||
|
|
# found. The "--without" options simply skip the check for that library.
|
||
|
|
# The effect on the search pattern is:
|
||
|
|
#
|
||
|
|
# (no options) - NcursesW, Ncurses, Curses
|
||
|
|
# --with-ncurses --with-ncursesw - NcursesW only [*]
|
||
|
|
# --without-ncurses --with-ncursesw - NcursesW only [*]
|
||
|
|
# --with-ncursesw - NcursesW only [*]
|
||
|
|
# --with-ncurses --without-ncursesw - Ncurses only [*]
|
||
|
|
# --with-ncurses - NcursesW, Ncurses [**]
|
||
|
|
# --without-ncurses --without-ncursesw - Curses only
|
||
|
|
# --without-ncursesw - Ncurses, Curses
|
||
|
|
# --without-ncurses - NcursesW, Curses
|
||
|
|
#
|
||
|
|
# [*] If the library is not found, abort the configure script.
|
||
|
|
#
|
||
|
|
# [**] If the second library (Ncurses) is not found, abort configure.
|
||
|
|
#
|
||
|
|
# The following preprocessor symbols may be defined by this macro if the
|
||
|
|
# appropriate conditions are met:
|
||
|
|
#
|
||
|
|
# HAVE_CURSES - if any SysV or X/Open Curses library found
|
||
|
|
# HAVE_CURSES_ENHANCED - if library supports X/Open Enhanced functions
|
||
|
|
# HAVE_CURSES_COLOR - if library supports color (enhanced functions)
|
||
|
|
# HAVE_CURSES_OBSOLETE - if library supports certain obsolete features
|
||
|
|
# HAVE_NCURSESW - if NcursesW (wide char) library is to be used
|
||
|
|
# HAVE_NCURSES - if the Ncurses library is to be used
|
||
|
|
#
|
||
|
|
# HAVE_CURSES_H - if <curses.h> is present and should be used
|
||
|
|
# HAVE_NCURSESW_H - if <ncursesw.h> should be used
|
||
|
|
# HAVE_NCURSES_H - if <ncurses.h> should be used
|
||
|
|
# HAVE_NCURSESW_CURSES_H - if <ncursesw/curses.h> should be used
|
||
|
|
# HAVE_NCURSES_CURSES_H - if <ncurses/curses.h> should be used
|
||
|
|
#
|
||
|
|
# (These preprocessor symbols are discussed later in this document.)
|
||
|
|
#
|
||
|
|
# The following output variable is defined by this macro; it is precious
|
||
|
|
# and may be overridden on the ./configure command line:
|
||
|
|
#
|
||
|
|
# CURSES_LIB - library to add to xxx_LDADD
|
||
|
|
#
|
||
|
|
# The library listed in CURSES_LIB is NOT added to LIBS by default. You
|
||
|
|
# need to add CURSES_LIB to the appropriate xxx_LDADD line in your
|
||
|
|
# Makefile.am. For example:
|
||
|
|
#
|
||
|
|
# prog_LDADD = @CURSES_LIB@
|
||
|
|
#
|
||
|
|
# If CURSES_LIB is set on the configure command line (such as by running
|
||
|
|
# "./configure CURSES_LIB=-lmycurses"), then the only header searched for
|
||
|
|
# is <curses.h>. The user may use the CPPFLAGS precious variable to
|
||
|
|
# override the standard #include search path. If the user needs to
|
||
|
|
# specify an alternative path for a library (such as for a non-standard
|
||
|
|
# NcurseW), the user should use the LDFLAGS variable.
|
||
|
|
#
|
||
|
|
# The following shell variables may be defined by this macro:
|
||
|
|
#
|
||
|
|
# ax_cv_curses - set to "yes" if any Curses library found
|
||
|
|
# ax_cv_curses_enhanced - set to "yes" if Enhanced functions present
|
||
|
|
# ax_cv_curses_color - set to "yes" if color functions present
|
||
|
|
# ax_cv_curses_obsolete - set to "yes" if obsolete features present
|
||
|
|
#
|
||
|
|
# ax_cv_ncursesw - set to "yes" if NcursesW library found
|
||
|
|
# ax_cv_ncurses - set to "yes" if Ncurses library found
|
||
|
|
# ax_cv_plaincurses - set to "yes" if plain Curses library found
|
||
|
|
# ax_cv_curses_which - set to "ncursesw", "ncurses", "plaincurses" or "no"
|
||
|
|
#
|
||
|
|
# These variables can be used in your configure.ac to determine the level
|
||
|
|
# of support you need from the Curses library. For example, if you must
|
||
|
|
# have either Ncurses or NcursesW, you could include:
|
||
|
|
#
|
||
|
|
# AX_WITH_CURSES
|
||
|
|
# if test "x$ax_cv_ncursesw" != xyes && test "x$ax_cv_ncurses" != xyes; then
|
||
|
|
# AX_MSG_ERROR([requires either NcursesW or Ncurses library])
|
||
|
|
# fi
|
||
|
|
#
|
||
|
|
# If any Curses library will do (but one must be present and must support
|
||
|
|
# color), you could use:
|
||
|
|
#
|
||
|
|
# AX_WITH_CURSES
|
||
|
|
# if test "x$ax_cv_curses" != xyes || test "x$ax_cv_curses_color" != xyes; then
|
||
|
|
# AC_MSG_ERROR([requires an X/Open-compatible Curses library with color])
|
||
|
|
# fi
|
||
|
|
#
|
||
|
|
# Certain preprocessor symbols and shell variables defined by this macro
|
||
|
|
# can be used to determine various features of the Curses library. In
|
||
|
|
# particular, HAVE_CURSES and ax_cv_curses are defined if the Curses
|
||
|
|
# library found conforms to the traditional SysV and/or X/Open Base Curses
|
||
|
|
# definition. Any working Curses library conforms to this level.
|
||
|
|
#
|
||
|
|
# HAVE_CURSES_ENHANCED and ax_cv_curses_enhanced are defined if the
|
||
|
|
# library supports the X/Open Enhanced Curses definition. In particular,
|
||
|
|
# the wide-character types attr_t, cchar_t and wint_t, the functions
|
||
|
|
# wattr_set() and wget_wch() and the macros WA_NORMAL and _XOPEN_CURSES
|
||
|
|
# are checked. The Ncurses library does NOT conform to this definition,
|
||
|
|
# although NcursesW does.
|
||
|
|
#
|
||
|
|
# HAVE_CURSES_COLOR and ax_cv_curses_color are defined if the library
|
||
|
|
# supports color functions and macros such as COLOR_PAIR, A_COLOR,
|
||
|
|
# COLOR_WHITE, COLOR_RED and init_pair(). These are NOT part of the
|
||
|
|
# X/Open Base Curses definition, but are part of the Enhanced set of
|
||
|
|
# functions. The Ncurses library DOES support these functions, as does
|
||
|
|
# NcursesW.
|
||
|
|
#
|
||
|
|
# HAVE_CURSES_OBSOLETE and ax_cv_curses_obsolete are defined if the
|
||
|
|
# library supports certain features present in SysV and BSD Curses but not
|
||
|
|
# defined in the X/Open definition. In particular, the functions
|
||
|
|
# getattrs(), getcurx() and getmaxx() are checked.
|
||
|
|
#
|
||
|
|
# To use the HAVE_xxx_H preprocessor symbols, insert the following into
|
||
|
|
# your system.h (or equivalent) header file:
|
||
|
|
#
|
||
|
|
# #if defined HAVE_NCURSESW_CURSES_H
|
||
|
|
# # include <ncursesw/curses.h>
|
||
|
|
# #elif defined HAVE_NCURSESW_H
|
||
|
|
# # include <ncursesw.h>
|
||
|
|
# #elif defined HAVE_NCURSES_CURSES_H
|
||
|
|
# # include <ncurses/curses.h>
|
||
|
|
# #elif defined HAVE_NCURSES_H
|

|
|
# # include <ncurses.h>
|
||
|
|
# #elif defined HAVE_CURSES_H
|
||
|
|
# # include <curses.h>
|
||
|
|
# #else
|
||
|
|
# # error "SysV or X/Open-compatible Curses header file required"
|
||
|
|
# #endif
|
||
|
|
#
|
||
|
|
# For previous users of this macro: you should not need to change anything
|
||
|
|
# in your configure.ac or Makefile.am, as the previous (serial 10)
|
||
|
|
# semantics are still valid. However, you should update your system.h (or
|
||
|
|
# equivalent) header file to the fragment shown above. You are encouraged
|
||
|
|
# also to make use of the extended functionality provided by this version
|
||
|
|
# of AX_WITH_CURSES, as well as in the additional macros
|
||
|
|
# AX_WITH_CURSES_PANEL, AX_WITH_CURSES_MENU and AX_WITH_CURSES_FORM.
