2073:
2074: dnl Macro to add for using GNU gettext.
2075:
2076: dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
2077: dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
2078: dnl default (if it is not specified or empty) is 'no-libtool'.
2079: dnl INTLSYMBOL should be 'external' for packages with no intl directory,
2080: dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
2081: dnl If INTLSYMBOL is 'use-libtool', then a libtool library
2082: dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
2083: dnl depending on --{enable,disable}-{shared,static} and on the presence of
2084: dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
2085: dnl $(top_builddir)/intl/libintl.a will be created.
2086: dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
2087: dnl implementations (in libc or libintl) without the ngettext() function
2088: dnl will be ignored. If NEEDSYMBOL is specified and is
2089: dnl 'need-formatstring-macros', then GNU gettext implementations that don't
2090: dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
2091: dnl INTLDIR is used to find the intl libraries. If empty,
2092: dnl the value `$(top_builddir)/intl/' is used.
2093: dnl
2094: dnl The result of the configuration is one of three cases:
2095: dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
2096: dnl and used.
2097: dnl Catalog format: GNU --> install in $(datadir)
2098: dnl Catalog extension: .mo after installation, .gmo in source tree
2099: dnl 2) GNU gettext has been found in the system's C library.
2100: dnl Catalog format: GNU --> install in $(datadir)
2101: dnl Catalog extension: .mo after installation, .gmo in source tree
2102: dnl 3) No internationalization, always use English msgid.
2103: dnl Catalog format: none
2104: dnl Catalog extension: none
2105: dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
2106: dnl The use of .gmo is historical (it was needed to avoid overwriting the
2107: dnl GNU format catalogs when building on a platform with an X/Open gettext),
2108: dnl but we keep it in order not to force irrelevant filename changes on the
2109: dnl maintainers.
