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/../..'.
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.

354 # fails when called from a subdirectory if $ac_aux_dir is relative

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
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.
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.
375 # Another solution, used here, is to always expand $ac_aux_dir to an

8616 dnl Macro to add for using GNU gettext.
8618 dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
8619 dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
8620 dnl default (if it is not specified or empty) is 'no-libtool'.
8621 dnl INTLSYMBOL should be 'external' for packages with no intl directory,
8622 dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
8623 dnl If INTLSYMBOL is 'use-libtool', then a libtool library
8624 dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
8625 dnl depending on --{enable,disable}-{shared,static} and on the presence of
8626 dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
8627 dnl $(top_builddir)/intl/libintl.a will be created.
8628 dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
8629 dnl implementations (in libc or libintl) without the ngettext() function
8630 dnl will be ignored. If NEEDSYMBOL is specified and is
8631 dnl 'need-formatstring-macros', then GNU gettext implementations that don't
8632 dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
8633 dnl INTLDIR is used to find the intl libraries. If empty,
8634 dnl the value `$(top_builddir)/intl/' is used.
8636 dnl The result of the configuration is one of three cases:
8637 dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
8639 dnl Catalog format: GNU --> install in $(datadir)
8640 dnl Catalog extension: .mo after installation, .gmo in source tree
8641 dnl 2) GNU gettext has been found in the system's C library.
8642 dnl Catalog format: GNU --> install in $(datadir)
8643 dnl Catalog extension: .mo after installation, .gmo in source tree
8644 dnl 3) No internationalization, always use English msgid.
8645 dnl Catalog format: none
8646 dnl Catalog extension: none
8647 dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
8648 dnl The use of .gmo is historical (it was needed to avoid overwriting the
8649 dnl GNU format catalogs when building on a platform with an X/Open gettext),
8650 dnl but we keep it in order not to force irrelevant filename changes on the
