# SYNOPSIS
#
# AX_BUILD_DATE_EPOCH(VARIABLE[, FORMAT[, ACTION-IF-FAIL]])
#
# DESCRIPTION
#
# Sets VARIABLE to a string representing the current time. It is
# formatted according to FORMAT if specified, otherwise it is formatted as
# the number of seconds (excluding leap seconds) since the UNIX epoch (01
# Jan 1970 00:00:00 UTC).
#
# If the SOURCE_DATE_EPOCH environment variable is set, it uses the value
# of that variable instead of the current time. See
# https://reproducible-builds.org/specs/source-date-epoch). If
# SOURCE_DATE_EPOCH is set but cannot be properly interpreted as a UNIX
# timestamp, then execute ACTION-IF-FAIL if specified, otherwise error.
#
# VARIABLE is AC_SUBST-ed.

#
# 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. 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.

#
# SYNOPSIS
#
# AX_WITH_CURSES_PANEL
# AX_WITH_CURSES_MENU
# AX_WITH_CURSES_FORM
#
# DESCRIPTION
#
# These macros try to find additional libraries that often come with
# SysV-compatible Curses. In particular, the Panel, Menu and Form
# libraries are searched, along with their header files. These macros
# depend on AX_WITH_CURSES.
#
# The following preprocessor symbols may be defined by these macros:
#
# By AX_WITH_CURSES_PANEL:
#
# HAVE_PANEL - if the Panel library is present
# HAVE_PANEL_H - if <panel.h> is present and should be used
# HAVE_NCURSES_PANEL_H - if <ncurses/panel.h> should be used
# HAVE_NCURSESW_PANEL_H - if <ncursesw/panel.h> should be used
#
# By AX_WITH_CURSES_MENU:
#
# HAVE_MENU - if the Menu library is present
# HAVE_MENU_H - if <menu.h> is present and should be used
# HAVE_NCURSES_MENU_H - if <ncurses/menu.h> should be used
# HAVE_NCURSESW_MENU_H - if <ncursesw/menu.h> should be used
#
# By AX_WITH_CURSES_FORM:
#
# HAVE_FORM - if the Form library is present
# HAVE_FORM_H - if <form.h> is present and should be used
# HAVE_NCURSES_FORM_H - if <ncurses/form.h> should be used
# HAVE_NCURSESW_FORM_H - if <ncursesw/form.h> should be used
#
# The following output variables may be defined by these macros; these are
# precious and may be overridden on the ./configure command line:
#
# PANEL_LIBS - library to add to xxx_LDADD before CURSES_LIBS
# MENU_LIBS - library to add to xxx_LDADD before CURSES_LIBS
# FORM_LIBS - library to add to xxx_LDADD before CURSES_LIBS
#
# In previous versions of this macro, the flags PANEL_LIB, MENU_LIB and
# FORM_LIB were defined. These have been renamed, in keeping with the
# variable scheme of PKG_CHECK_MODULES, which should eventually supersede
# the use of AX_WITH_CURSES and AX_WITH_CURSES_* macros. These libraries
# are NOT added to LIBS by default. You need to add them to the
# appropriate xxx_LDADD line in your Makefile.am in front of the
# equivalent CURSES_LIBS incantation. For example:
#
# prog_LDADD = @PANEL_LIBS@ @CURSES_LIBS@
#
# If one of the xxx_LIBS variables is set on the configure command line
# (such as by running "./configure PANEL_LIBS=-lmypanel"), then the header
# file searched must NOT contain a subpath. In this case, in other words,
# only <panel.h> would be searched for. The user may use the CPPFLAGS
# precious variable to override the standard #include search path.
#
# The following shell variables may be defined by these macros:
#
# ax_cv_panel - set to "yes" if Panels library is present
# ax_cv_menu - set to "yes" if Menu library is present
# ax_cv_form - set to "yes" if Form library is present
#
# These variables can be used in your configure.ac to determine whether a
# library you require is actually present. For example:
#
# AX_WITH_CURSES
# if test "x$ax_cv_curses" != xyes; then
# AC_MSG_ERROR([requires a SysV or X/Open-compatible Curses library])
# fi
# AX_WITH_CURSES_PANEL
# if test "x$ax_cv_panel" != xyes; then
# AC_MSG_ERROR([requires the Curses Panel library])
# fi
#
# To use the HAVE_xxx_H preprocessor symbols, insert the following into
# your system.h (or equivalent) header file:
#
# For AX_WITH_CURSES_PANEL:
#
# #if defined HAVE_NCURSESW_PANEL_H
# # include <ncursesw/panel.h>
# #elif defined HAVE_NCURSES_PANEL_H
# # include <ncurses/panel.h>
# #elif defined HAVE_PANEL_H
# # include <panel.h>
# #else
# # error "SysV-compatible Curses Panel header file required"
# #endif
#
# For AX_WITH_CURSES_MENU:
#
# #if defined HAVE_NCURSESW_MENU_H
# # include <ncursesw/menu.h>
# #elif defined HAVE_NCURSES_MENU_H
# # include <ncurses/menu.h>
# #elif defined HAVE_MENU_H
# # include <menu.h>
# #else
# # error "SysV-compatible Curses Menu header file required"
# #endif
#
# For AX_WITH_CURSES_FORM:
#
# #if defined HAVE_NCURSESW_FORM_H
# # include <ncursesw/form.h>
# #elif defined HAVE_NCURSES_FORM_H
# # include <ncurses/form.h>
# #elif defined HAVE_FORM_H
# # include <form.h>
# #else
# # error "SysV-compatible Curses Form header file required"
# #endif

dnl Macro to add for using GNU gettext.
dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
dnl default (if it is not specified or empty) is 'no-libtool'.
dnl INTLSYMBOL should be 'external' for packages with no intl directory,
dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
dnl If INTLSYMBOL is 'use-libtool', then a libtool library
dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
dnl depending on --{enable,disable}-{shared,static} and on the presence of
dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
dnl $(top_builddir)/intl/libintl.a will be created.
dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext

dnl will be ignored. If NEEDSYMBOL is specified and is

dnl The result of the configuration is one of three cases:
dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
dnl and used.
dnl Catalog format: GNU --> install in $(datadir)
dnl Catalog extension: .mo after installation, .gmo in source tree
dnl 2) GNU gettext has been found in the system's C library.
dnl Catalog format: GNU --> install in $(datadir)

dnl 3) No internationalization, always use English msgid.
dnl Catalog format: none
dnl Catalog extension: none
dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
dnl The use of .gmo is historical (it was needed to avoid overwriting the
dnl GNU format catalogs when building on a platform with an X/Open gettext),
dnl but we keep it in order not to force irrelevant filename changes on the
