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. +# +# LICENSE +# +# Copyright (c) 2009 Mark Pulford <mark@kyne.com.au> +# Copyright (c) 2009 Damian Pietras <daper@daper.net> +# Copyright (c) 2011 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.
