| 264 | dnl Macro to add for using GNU gettext. |
| 265 | |
| 266 | dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]). |
| 267 | dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The |
| 268 | dnl default (if it is not specified or empty) is 'no-libtool'. |
| 269 | dnl INTLSYMBOL should be 'external' for packages with no intl directory, |
| 270 | dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory. |
| 271 | dnl If INTLSYMBOL is 'use-libtool', then a libtool library |
| 272 | dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static, |
| 273 | dnl depending on --{enable,disable}-{shared,static} and on the presence of |
| 274 | dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library |
| 275 | dnl $(top_builddir)/intl/libintl.a will be created. |
| 276 | dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext |
| 277 | dnl implementations (in libc or libintl) without the ngettext() function |
| 278 | dnl will be ignored. If NEEDSYMBOL is specified and is |
| 279 | dnl 'need-formatstring-macros', then GNU gettext implementations that don't |
| 280 | dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored. |
| 281 | dnl INTLDIR is used to find the intl libraries. If empty, |
Theodore Ts'o | 9361395 | 2014-07-03 23:44:13 -0400 | [diff] [blame] | 282 | dnl the value '$(top_builddir)/intl/' is used. |
Theodore Ts'o | a04eba3 | 2003-05-03 16:35:17 -0400 | [diff] [blame] | 283 | dnl |
| 284 | dnl The result of the configuration is one of three cases: |
| 285 | dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled |
| 286 | dnl and used. |
| 287 | dnl Catalog format: GNU --> install in $(datadir) |
| 288 | dnl Catalog extension: .mo after installation, .gmo in source tree |
| 289 | dnl 2) GNU gettext has been found in the system's C library. |
| 290 | dnl Catalog format: GNU --> install in $(datadir) |
| 291 | dnl Catalog extension: .mo after installation, .gmo in source tree |
| 292 | dnl 3) No internationalization, always use English msgid. |
| 293 | dnl Catalog format: none |
| 294 | dnl Catalog extension: none |
| 295 | dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur. |
| 296 | dnl The use of .gmo is historical (it was needed to avoid overwriting the |
| 297 | dnl GNU format catalogs when building on a platform with an X/Open gettext), |
| 298 | dnl but we keep it in order not to force irrelevant filename changes on the |
| 299 | dnl maintainers. |
