394# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
395# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
396# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
397#
398# Of course, Automake must honor this variable whenever it calls a
399# tool from the auxiliary directory. The problem is that $srcdir (and
400# therefore $ac_aux_dir as well) can be either absolute or relative,
401# depending on how configure is run. This is pretty annoying, since
402# it makes $ac_aux_dir quite unusable in subdirectories: in the top
403# source directory, any form will work fine, but in subdirectories a
404# relative path needs to be adjusted first.
405#
406# $ac_aux_dir/missing
407# fails when called from a subdirectory if $ac_aux_dir is relative
408# $top_srcdir/$ac_aux_dir/missing
409# fails if $ac_aux_dir is absolute,
410# fails when called from a subdirectory in a VPATH build with
411# a relative $ac_aux_dir
412#
413# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
414# are both prefixed by $srcdir. In an in-source build this is usually
415# harmless because $srcdir is `.', but things will broke when you
416# start a VPATH build or use an absolute $srcdir.
417#
418# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
419# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
420# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
421# and then we would define $MISSING as
422# MISSING="\${SHELL} $am_aux_dir/missing"
423# This will work as long as MISSING is not called from configure, because
424# unfortunately $(top_srcdir) has no meaning in configure.
425# However there are other variables, like CC, which are often used in
426# configure, and could therefore not use this "fixed" $ac_aux_dir.
427#
428# Another solution, used here, is to always expand $ac_aux_dir to an
429# absolute PATH. The drawback is that using absolute paths prevent a
430# configured tree to be moved without reconfiguration.

1172
1173dnl Macro to add for using GNU gettext.
1174
1175dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
1176dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
1177dnl default (if it is not specified or empty) is 'no-libtool'.
1178dnl INTLSYMBOL should be 'external' for packages with no intl directory,
1179dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
1180dnl If INTLSYMBOL is 'use-libtool', then a libtool library
1181dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
1182dnl depending on --{enable,disable}-{shared,static} and on the presence of
1183dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
1184dnl $(top_builddir)/intl/libintl.a will be created.
1185dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
1186dnl implementations (in libc or libintl) without the ngettext() function
1187dnl will be ignored.
1188dnl INTLDIR is used to find the intl libraries. If empty,
1189dnl the value `$(top_builddir)/intl/' is used.
1190dnl
1191dnl The result of the configuration is one of three cases:
1192dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
1193dnl and used.
1194dnl Catalog format: GNU --> install in $(datadir)
1195dnl Catalog extension: .mo after installation, .gmo in source tree
1196dnl 2) GNU gettext has been found in the system's C library.
1197dnl Catalog format: GNU --> install in $(datadir)
1198dnl Catalog extension: .mo after installation, .gmo in source tree
1199dnl 3) No internationalization, always use English msgid.
1200dnl Catalog format: none
1201dnl Catalog extension: none
1202dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
1203dnl The use of .gmo is historical (it was needed to avoid overwriting the
1204dnl GNU format catalogs when building on a platform with an X/Open gettext),
1205dnl but we keep it in order not to force irrelevant filename changes on the
1206dnl maintainers.
