| 2048 | dnl Macro to add for using GNU gettext. |
| 2049 | |
| 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. |
| 2067 | dnl |
| 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 |
| 2070 | dnl and used. |
| 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 |
| 2083 | dnl maintainers. |
