341# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
342# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
343# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
344#
345# Of course, Automake must honor this variable whenever it calls a
346# tool from the auxiliary directory. The problem is that $srcdir (and
347# therefore $ac_aux_dir as well) can be either absolute or relative,
348# depending on how configure is run. This is pretty annoying, since
349# it makes $ac_aux_dir quite unusable in subdirectories: in the top
350# source directory, any form will work fine, but in subdirectories a
351# relative path needs to be adjusted first.
352#
353# $ac_aux_dir/missing
354# fails when called from a subdirectory if $ac_aux_dir is relative
355# $top_srcdir/$ac_aux_dir/missing
356# fails if $ac_aux_dir is absolute,
357# fails when called from a subdirectory in a VPATH build with
358# a relative $ac_aux_dir
359#
360# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
361# are both prefixed by $srcdir. In an in-source build this is usually
362# harmless because $srcdir is `.', but things will broke when you
363# start a VPATH build or use an absolute $srcdir.
364#
365# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
366# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
367# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
368# and then we would define $MISSING as
369# MISSING="\${SHELL} $am_aux_dir/missing"
370# This will work as long as MISSING is not called from configure, because
371# unfortunately $(top_srcdir) has no meaning in configure.
372# However there are other variables, like CC, which are often used in
373# configure, and could therefore not use this "fixed" $ac_aux_dir.
374#
375# Another solution, used here, is to always expand $ac_aux_dir to an
376# absolute PATH. The drawback is that using absolute paths prevent a
377# configured tree to be moved without reconfiguration.

842dnl Macro to add for using GNU gettext.
843
844dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
845dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
846dnl default (if it is not specified or empty) is 'no-libtool'.
847dnl INTLSYMBOL should be 'external' for packages with no intl directory,
848dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
849dnl If INTLSYMBOL is 'use-libtool', then a libtool library
850dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
851dnl depending on --{enable,disable}-{shared,static} and on the presence of
852dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
853dnl $(top_builddir)/intl/libintl.a will be created.
854dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
855dnl implementations (in libc or libintl) without the ngettext() function
856dnl will be ignored. If NEEDSYMBOL is specified and is
857dnl 'need-formatstring-macros', then GNU gettext implementations that don't
858dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
859dnl INTLDIR is used to find the intl libraries. If empty,
860dnl the value `$(top_builddir)/intl/' is used.
861dnl
862dnl The result of the configuration is one of three cases:
863dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
864dnl and used.
865dnl Catalog format: GNU --> install in $(datadir)
866dnl Catalog extension: .mo after installation, .gmo in source tree
867dnl 2) GNU gettext has been found in the system's C library.
868dnl Catalog format: GNU --> install in $(datadir)
869dnl Catalog extension: .mo after installation, .gmo in source tree
870dnl 3) No internationalization, always use English msgid.
871dnl Catalog format: none
872dnl Catalog extension: none
873dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
874dnl The use of .gmo is historical (it was needed to avoid overwriting the
875dnl GNU format catalogs when building on a platform with an X/Open gettext),
876dnl but we keep it in order not to force irrelevant filename changes on the
877dnl maintainers.
