2048 dnl Macro to add for using GNU gettext.
2050 dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
2051 dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
2052 dnl default (if it is not specified or empty) is 'no-libtool'.
2053 dnl INTLSYMBOL should be 'external' for packages with no intl directory,
2054 dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
2055 dnl If INTLSYMBOL is 'use-libtool', then a libtool library
2056 dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
2057 dnl depending on --{enable,disable}-{shared,static} and on the presence of
2058 dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
2059 dnl $(top_builddir)/intl/libintl.a will be created.
2060 dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
2061 dnl implementations (in libc or libintl) without the ngettext() function
2062 dnl will be ignored. If NEEDSYMBOL is specified and is
2063 dnl 'need-formatstring-macros', then GNU gettext implementations that don't
2064 dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
2065 dnl INTLDIR is used to find the intl libraries. If empty,
2066 dnl the value `$(top_builddir)/intl/' is used.
2068 dnl The result of the configuration is one of three cases:
2069 dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
2071 dnl Catalog format: GNU --> install in $(datadir)
2072 dnl Catalog extension: .mo after installation, .gmo in source tree
2073 dnl 2) GNU gettext has been found in the system's C library.
2074 dnl Catalog format: GNU --> install in $(datadir)
2075 dnl Catalog extension: .mo after installation, .gmo in source tree
2076 dnl 3) No internationalization, always use English msgid.
2077 dnl Catalog format: none
2078 dnl Catalog extension: none
2079 dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
2080 dnl The use of .gmo is historical (it was needed to avoid overwriting the
2081 dnl GNU format catalogs when building on a platform with an X/Open gettext),
2082 dnl but we keep it in order not to force irrelevant filename changes on the
