# Makefile.in for building crosstool-NG
# This file serves as source for the ./configure operation
# This series of test is here because GNU make 3.81 will *not* use MAKEFLAGS
# to set additional flags in the current Makfile ( see:
# http://savannah.gnu.org/bugs/?20501 ), although the make manual says it
# should ( see: http://www.gnu.org/software/make/manual/make.html#Options_002fRecursion )
# so we have to work it around by calling ourselves back if needed
# So why do we need not to use the built rules and variables? Because we
# need to generate scripts/crosstool-NG.sh from scripts/crosstool-NG.sh.in
# and there is a built-in implicit rule '%.sh:' that has neither a pre-requisite
# nor a command associated, and that built-in implicit rule takes precedence
# over our non-built-in implicit rule '%: %.in', below.
# CT_MAKEFLAGS will be used later, below...
# Do not print directories as we descend into them
ifeq ($(filter --no-print-directory,$(MAKEFLAGS)),)
CT_MAKEFLAGS += --no-print-directory
endif
# Use neither builtin rules, nor builtin variables
# Note: dual test, because if -R and -r are given on the command line
# (who knows?), MAKEFLAGS contains 'Rr' instead of '-Rr', while adding
# '-Rr' to MAKEFLAGS adds it literaly ( and does not add 'Rr' )
# Further: quad test because the flags 'rR' and '-rR' can be reordered.

#
# 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.

# DESCRIPTION
#
# AX_REQUIRE_DEFINED is a simple helper for making sure other macros have

# ===========================================================================
#
# 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

dnl
dnl This file can be used in projects which are not available under
dnl the GNU General Public License or the GNU Library General Public
dnl License but which still want to provide support for the GNU gettext
dnl functionality.
dnl Please note that the actual code of the GNU gettext library is covered
dnl by the GNU Library General Public License, and the rest of the GNU
dnl gettext package is covered by the GNU General Public License.
dnl They are *not* in the public domain.
dnl Authors:
dnl Ulrich Drepper <drepper@cygnus.com>, 1995-2000.
dnl Bruno Haible <haible@clisp.cons.org>, 2000-2006, 2008-2010.
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 $(top_builddir)/intl/libintl.a will be created.
dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
dnl implementations (in libc or libintl) without the ngettext() function
dnl will be ignored. If NEEDSYMBOL is specified and is
dnl 'need-formatstring-macros', then GNU gettext implementations that don't
dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
dnl INTLDIR is used to find the intl libraries. If empty,
dnl the value '$(top_builddir)/intl/' is used.
dnl
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 Catalog extension: .mo after installation, .gmo in source tree
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
dnl maintainers.

## There are various ways to get dependency output from gcc. Here's
## why we pick this rather obscure method:
## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say). Also, it might not be
## supported by the other compilers which use the 'gcc' depmode.
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the "deleted header file" problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.
## Some versions of gcc put a space before the ':'. On the theory
## that the space means something, we add a space to the output as
## well. hp depmode also adds that space, but also prefixes the VPATH
