# Macro to add for using GNU gettext.
|
|
# Ulrich Drepper <drepper@cygnus.com>, 1995.
|
|
#
|
|
# This file can be copied and used freely without restrictions. It can
|
|
# be used in projects which are not available under the GNU General Public
|
|
# License but which still want to provide support for the GNU gettext
|
|
# functionality.
|
|
# Please note that the actual code of GNU gettext is covered by the GNU
|
|
# General Public License and is *not* in the public domain.
|
|
|
|
# serial 10
|
|
|
|
dnl Note that we always use own gettext implementation, even if we found
|
|
dnl working system one. We have some own modifications in our implementation
|
|
dnl and we rely on them.
|
|
|
|
dnl Usage: AM_WITH_NLS([TOOLSYMBOL], [NEEDSYMBOL], [LIBDIR]).
|
|
dnl If TOOLSYMBOL is specified and is 'use-libtool', then a libtool library
|
|
dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
|
|
dnl depending on --{enable,disable}-{shared,static} and on the presence of
|
|
dnl AM-DISABLE-SHARED). Otherwise, a static library
|
|
dnl $(top_builddir)/intl/libintl.a will be created.
|
|
dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
|
|
dnl implementations (in libc or libintl) without the ngettext() function
|
|
dnl will be ignored.
|
|
dnl LIBDIR is used to find the intl libraries. If empty,
|
|
dnl the value `$(top_builddir)/intl/' is used.
|
|
dnl
|
|
dnl The result of the configuration is one of three cases:
|
|
dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
|
|
dnl and used.
|
|
dnl Catalog format: GNU --> install in $(datadir)
|
|
dnl Catalog extension: .mo after installation, .gmo in source tree
|
|
dnl 2) GNU gettext has been found in the system's C library.
|
|
dnl Catalog format: GNU --> install in $(datadir)
|
|
dnl Catalog extension: .mo after installation, .gmo in source tree
|
|
dnl 3) No internationalization, always use English msgid.
|
|
dnl Catalog format: none
|
|
dnl Catalog extension: none
|
|
dnl The use of .gmo is historical (it was needed to avoid overwriting the
|
|
dnl GNU format catalogs when building on a platform with an X/Open gettext),
|
|
dnl but we keep it in order not to force irrelevant filename changes on the
|
|
dnl maintainers.
