# 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.

1270
dnl Macro to add for using GNU gettext.
1271
1272
dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
1273
dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
1274
dnl default (if it is not specified or empty) is 'no-libtool'.
1275
dnl INTLSYMBOL should be 'external' for packages with no intl directory,
1276
dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
1277
dnl If INTLSYMBOL is 'use-libtool', then a libtool library
1278
dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
1279
dnl depending on --{enable,disable}-{shared,static} and on the presence of
1280
dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
1281
dnl $(top_builddir)/intl/libintl.a will be created.
1282
dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
1283
dnl implementations (in libc or libintl) without the ngettext() function
1284
dnl will be ignored. If NEEDSYMBOL is specified and is
1285
dnl 'need-formatstring-macros', then GNU gettext implementations that don't
1286
dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
1287
dnl INTLDIR is used to find the intl libraries. If empty,
1288
dnl the value `$(top_builddir)/intl/' is used.
1289
dnl
1290
dnl The result of the configuration is one of three cases:
1291
dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
1292
dnl and used.
1293
dnl Catalog format: GNU --> install in $(datadir)
1294
dnl Catalog extension: .mo after installation, .gmo in source tree
1295
dnl 2) GNU gettext has been found in the system's C library.
1296
dnl Catalog format: GNU --> install in $(datadir)
1297
dnl Catalog extension: .mo after installation, .gmo in source tree
1298
dnl 3) No internationalization, always use English msgid.
1299
dnl Catalog format: none
1300
dnl Catalog extension: none
1301
dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
1302
dnl The use of .gmo is historical (it was needed to avoid overwriting the
1303
dnl GNU format catalogs when building on a platform with an X/Open gettext),
1304
dnl but we keep it in order not to force irrelevant filename changes on the
1305
dnl maintainers.
