41dnl Macro to add for using GNU gettext.
42
43dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
44dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
45dnl    default (if it is not specified or empty) is 'no-libtool'.
46dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
47dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
48dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
49dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
50dnl    depending on --{enable,disable}-{shared,static} and on the presence of
51dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
52dnl    $(top_builddir)/intl/libintl.a will be created.
53dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
54dnl    implementations (in libc or libintl) without the ngettext() function
55dnl    will be ignored.  If NEEDSYMBOL is specified and is
56dnl    'need-formatstring-macros', then GNU gettext implementations that don't
57dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
58dnl INTLDIR is used to find the intl libraries.  If empty,
59dnl    the value `$(top_builddir)/intl/' is used.
60dnl
61dnl The result of the configuration is one of three cases:
62dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
63dnl    and used.
64dnl    Catalog format: GNU --> install in $(datadir)
65dnl    Catalog extension: .mo after installation, .gmo in source tree
66dnl 2) GNU gettext has been found in the system's C library.
67dnl    Catalog format: GNU --> install in $(datadir)
68dnl    Catalog extension: .mo after installation, .gmo in source tree
69dnl 3) No internationalization, always use English msgid.
70dnl    Catalog format: none
71dnl    Catalog extension: none
72dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
73dnl The use of .gmo is historical (it was needed to avoid overwriting the
74dnl GNU format catalogs when building on a platform with an X/Open gettext),
75dnl but we keep it in order not to force irrelevant filename changes on the
76dnl maintainers.

803# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
804# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
805# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
806#
807# Of course, Automake must honor this variable whenever it calls a
808# tool from the auxiliary directory.  The problem is that $srcdir (and
809# therefore $ac_aux_dir as well) can be either absolute or relative,
810# depending on how configure is run.  This is pretty annoying, since
811# it makes $ac_aux_dir quite unusable in subdirectories: in the top
812# source directory, any form will work fine, but in subdirectories a
813# relative path needs to be adjusted first.
814#
815# $ac_aux_dir/missing
816#    fails when called from a subdirectory if $ac_aux_dir is relative
817# $top_srcdir/$ac_aux_dir/missing
818#    fails if $ac_aux_dir is absolute,
819#    fails when called from a subdirectory in a VPATH build with
820#          a relative $ac_aux_dir
821#
822# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
823# are both prefixed by $srcdir.  In an in-source build this is usually
824# harmless because $srcdir is `.', but things will broke when you
825# start a VPATH build or use an absolute $srcdir.
826#
827# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
828# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
829#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
830# and then we would define $MISSING as
831#   MISSING="\${SHELL} $am_aux_dir/missing"
832# This will work as long as MISSING is not called from configure, because
833# unfortunately $(top_srcdir) has no meaning in configure.
