20 dnl Macro to add for using GNU gettext.
21
22 dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
23 dnl INTLSYMBOL must be one of 'external', 'use-libtool', 'here'.
24 dnl INTLSYMBOL should be 'external' for packages other than GNU gettext.
25 dnl It should be 'use-libtool' for the packages 'gettext-runtime' and
26 dnl 'gettext-tools'.
27 dnl It should be 'here' for the package 'gettext-runtime/intl'.
28 dnl If INTLSYMBOL is 'here', then a libtool library
29 dnl $(top_builddir)/libintl.la will be created (shared and/or static,
30 dnl depending on --{enable,disable}-{shared,static} and on the presence of
31 dnl AM-DISABLE-SHARED).
32 dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
33 dnl implementations (in libc or libintl) without the ngettext() function
34 dnl will be ignored. If NEEDSYMBOL is specified and is
35 dnl 'need-formatstring-macros', then GNU gettext implementations that don't
36 dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
37 dnl INTLDIR is used to find the intl libraries. If empty,
38 dnl the value '$(top_builddir)/intl/' is used.
39 dnl
40 dnl The result of the configuration is one of three cases:
41 dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
42 dnl and used.
43 dnl Catalog format: GNU --> install in $(datadir)
44 dnl Catalog extension: .mo after installation, .gmo in source tree
45 dnl 2) GNU gettext has been found in the system's C library.
46 dnl Catalog format: GNU --> install in $(datadir)
47 dnl Catalog extension: .mo after installation, .gmo in source tree
48 dnl 3) No internationalization, always use English msgid.
49 dnl Catalog format: none
50 dnl Catalog extension: none
51 dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
52 dnl The use of .gmo is historical (it was needed to avoid overwriting the
53 dnl GNU format catalogs when building on a platform with an X/Open gettext),
54 dnl but we keep it in order not to force irrelevant filename changes on the
55 dnl maintainers.
