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.
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
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

5892 dnl Macro to add for using GNU gettext.
5894 dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
5895 dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
5896 dnl default (if it is not specified or empty) is 'no-libtool'.
5897 dnl INTLSYMBOL should be 'external' for packages with no intl directory,
5898 dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
5899 dnl If INTLSYMBOL is 'use-libtool', then a libtool library
5900 dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
5901 dnl depending on --{enable,disable}-{shared,static} and on the presence of
5902 dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
5903 dnl $(top_builddir)/intl/libintl.a will be created.
5904 dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
5905 dnl implementations (in libc or libintl) without the ngettext() function
5906 dnl will be ignored. If NEEDSYMBOL is specified and is
5907 dnl 'need-formatstring-macros', then GNU gettext implementations that don't
5908 dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
5909 dnl INTLDIR is used to find the intl libraries. If empty,
5910 dnl the value `$(top_builddir)/intl/' is used.
5912 dnl The result of the configuration is one of three cases:
5913 dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
5915 dnl Catalog format: GNU --> install in $(datadir)
5916 dnl Catalog extension: .mo after installation, .gmo in source tree
5917 dnl 2) GNU gettext has been found in the system's C library.
5918 dnl Catalog format: GNU --> install in $(datadir)
5919 dnl Catalog extension: .mo after installation, .gmo in source tree
5920 dnl 3) No internationalization, always use English msgid.
5921 dnl Catalog format: none
5922 dnl Catalog extension: none
5923 dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
5924 dnl The use of .gmo is historical (it was needed to avoid overwriting the
5925 dnl GNU format catalogs when building on a platform with an X/Open gettext),
5926 dnl but we keep it in order not to force irrelevant filename changes on the

5955 dnl the configure script would need to contain the same shell code
5956 dnl again, outside any 'if'. There are two solutions:
5957 dnl - Invoke AM_ICONV_LINKFLAGS_BODY here, outside any 'if'.
5958 dnl - Control the expansions in more detail using AC_PROVIDE_IFELSE.
