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. Finding libraries will first be attempted by using -# pkg-config, and should the pkg-config files not be available, will -# fallback to combinations of known flags itself. -# -# 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 variables are defined by this macro; they are -# precious and may be overridden on the ./configure command line: -# -# CURSES_LIBS - library to add to xxx_LDADD -# CURSES_CFLAGS - include paths to add to xxx_CPPFLAGS -# -# In previous versions of this macro, the flags CURSES_LIB and -# CURSES_CPPFLAGS were defined. These have been renamed, in keeping with -# AX_WITH_CURSES's close bigger brother, PKG_CHECK_MODULES, which should -# eventually supersede the use of AX_WITH_CURSES. Neither the library -# listed in CURSES_LIBS, nor the flags in CURSES_CFLAGS are added to LIBS, -# respectively CPPFLAGS, by default. You need to add both to the -# appropriate xxx_LDADD/xxx_CPPFLAGS line in your Makefile.am. For -# example: -# -# prog_LDADD = @CURSES_LIBS@ -# prog_CPPFLAGS = @CURSES_CFLAGS@ -# -# If CURSES_LIBS is set on the configure command line (such as by running -# "./configure CURSES_LIBS=-lmycurses"), then the only header searched for -# is <curses.h>. 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 -# AC_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. -# -# LICENSE -# -# Copyright (c) 2009 Mark Pulford <mark@kyne.com.au> -# Copyright (c) 2009 Damian Pietras <daper@daper.net> -# Copyright (c) 2012 Reuben Thomas <rrt@sc3d.org> -# Copyright (c) 2011 John Zaitseff <J.Zaitseff@zap.org.au> -# -# This program is free software: you can redistribute it and/or modify it -# under the terms of the GNU General Public License as published by the -# Free Software Foundation, either version 3 of the License, or (at your -# option) any later version. -# -# This program is distributed in the hope that it will be useful, but -# WITHOUT ANY WARRANTY; without even the implied warranty of -# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
