| |
| dnl Macro to add for using GNU gettext. |
| |
| dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]). |
| dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The |
| dnl default (if it is not specified or empty) is 'no-libtool'. |
| dnl INTLSYMBOL should be 'external' for packages with no intl directory, |
| dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory. |
| dnl If INTLSYMBOL 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). If INTLSYMBOL is 'no-libtool', a static library |
| dnl $(top_builddir)/intl/libintl.a will be created. |
| dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext |
| dnl implementations (in libc or libintl) without the ngettext() function |
| dnl will be ignored. If NEEDSYMBOL is specified and is |
| dnl 'need-formatstring-macros', then GNU gettext implementations that don't |
| dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored. |
| dnl INTLDIR is used to find the intl libraries. If empty, |
| dnl the value `$(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 If INTLSYMBOL is 'external', only cases 2 and 3 can occur. |
| 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. |
