522 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
523 # are both prefixed by $srcdir. In an in-source build this is usually
524 # harmless because $srcdir is `.', but things will broke when you
525 # start a VPATH build or use an absolute $srcdir.
526 #
527 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
528 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
529 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
530 # and then we would define $MISSING as
531 # MISSING="\${SHELL} $am_aux_dir/missing"
532 # This will work as long as MISSING is not called from configure, because
533 # unfortunately $(top_srcdir) has no meaning in configure.
534 # However there are other variables, like CC, which are often used in
535 # configure, and could therefore not use this "fixed" $ac_aux_dir.
536 #
537 # Another solution, used here, is to always expand $ac_aux_dir to an
538 # absolute PATH. The drawback is that using absolute paths prevent a
539 # configured tree to be moved without reconfiguration.
541 # Rely on autoconf to set up CDPATH properly.

999 dnl Macro to add for using GNU gettext.
1001 dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
1002 dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
1003 dnl default (if it is not specified or empty) is 'no-libtool'.
1004 dnl INTLSYMBOL should be 'external' for packages with no intl directory,
1005 dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
1006 dnl If INTLSYMBOL is 'use-libtool', then a libtool library
1007 dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
1008 dnl depending on --{enable,disable}-{shared,static} and on the presence of
1009 dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
1010 dnl $(top_builddir)/intl/libintl.a will be created.
1011 dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
1012 dnl implementations (in libc or libintl) without the ngettext() function
1013 dnl will be ignored. If NEEDSYMBOL is specified and is
1014 dnl 'need-formatstring-macros', then GNU gettext implementations that don't
1015 dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
1016 dnl INTLDIR is used to find the intl libraries. If empty,
1017 dnl the value `$(top_builddir)/intl/' is used.
1018 dnl
1019 dnl The result of the configuration is one of three cases:
1020 dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
1021 dnl and used.
1022 dnl Catalog format: GNU --> install in $(datadir)
1023 dnl Catalog extension: .mo after installation, .gmo in source tree
1024 dnl 2) GNU gettext has been found in the system's C library.
1025 dnl Catalog format: GNU --> install in $(datadir)
1026 dnl Catalog extension: .mo after installation, .gmo in source tree
1027 dnl 3) No internationalization, always use English msgid.
1028 dnl Catalog format: none
1029 dnl Catalog extension: none
1030 dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
1031 dnl The use of .gmo is historical (it was needed to avoid overwriting the
1032 dnl GNU format catalogs when building on a platform with an X/Open gettext),
1033 dnl but we keep it in order not to force irrelevant filename changes on the
1034 dnl maintainers.
