22 dnl Macro to add for using GNU gettext.
24 dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
25 dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
26 dnl default (if it is not specified or empty) is 'no-libtool'.
27 dnl INTLSYMBOL should be 'external' for packages with no intl directory,
28 dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
29 dnl If INTLSYMBOL is 'use-libtool', then a libtool library
30 dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
31 dnl depending on --{enable,disable}-{shared,static} and on the presence of
32 dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
33 dnl $(top_builddir)/intl/libintl.a will be created.
34 dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
35 dnl implementations (in libc or libintl) without the ngettext() function
37 dnl INTLDIR is used to find the intl libraries. If empty,
38 dnl the value `$(top_builddir)/intl/' is used.
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
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
