15 dnl Usage: AM_WITH_NLS([TOOLSYMBOL], [NEEDSYMBOL], [LIBDIR]).
16 dnl If TOOLSYMBOL is specified and is 'use-libtool', then a libtool library
17 dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
18 dnl depending on --{enable,disable}-{shared,static} and on the presence of
19 dnl AM-DISABLE-SHARED). Otherwise, a static library
20 dnl $(top_builddir)/intl/libintl.a will be created.
21 dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
22 dnl implementations (in libc or libintl) without the ngettext() function
23 dnl will be ignored.
24 dnl LIBDIR is used to find the intl libraries. If empty,
25 dnl the value `$(top_builddir)/intl/' is used.
26 dnl
27 dnl The result of the configuration is one of three cases:
28 dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
29 dnl and used.
30 dnl Catalog format: GNU --> install in $(datadir)
31 dnl Catalog extension: .mo after installation, .gmo in source tree
32 dnl 2) GNU gettext has been found in the system's C library.
33 dnl Catalog format: GNU --> install in $(datadir)
34 dnl Catalog extension: .mo after installation, .gmo in source tree
35 dnl 3) No internationalization, always use English msgid.
36 dnl Catalog format: none
37 dnl Catalog extension: none
38 dnl The use of .gmo is historical (it was needed to avoid overwriting the
39 dnl GNU format catalogs when building on a platform with an X/Open gettext),
40 dnl but we keep it in order not to force irrelevant filename changes on the
41 dnl maintainers.
