20 | dnl Macro to add for using GNU gettext. | ||
21 | |||
22 | dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]). | ||
23 | dnl INTLSYMBOL must be one of 'external', 'use-libtool'. | ||
24 | dnl INTLSYMBOL should be 'external' for packages other than GNU gettext, and | ||
25 | dnl 'use-libtool' for the packages 'gettext-runtime' and 'gettext-tools'. | ||
26 | dnl If INTLSYMBOL is 'use-libtool', then a libtool library | ||
27 | dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static, | ||
28 | dnl depending on --{enable,disable}-{shared,static} and on the presence of | ||
29 | dnl AM-DISABLE-SHARED). | ||
30 | dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext | ||
31 | dnl implementations (in libc or libintl) without the ngettext() function | ||
32 | dnl will be ignored. If NEEDSYMBOL is specified and is | ||
33 | dnl 'need-formatstring-macros', then GNU gettext implementations that don't | ||
34 | dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored. | ||
35 | dnl INTLDIR is used to find the intl libraries. If empty, | ||
36 | dnl the value '$(top_builddir)/intl/' is used. | ||
37 | dnl | ||
38 | dnl The result of the configuration is one of three cases: | ||
39 | dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled | ||
40 | dnl and used. | ||
41 | dnl Catalog format: GNU --> install in $(datadir) | ||
42 | dnl Catalog extension: .mo after installation, .gmo in source tree | ||
43 | dnl 2) GNU gettext has been found in the system's C library. | ||
44 | dnl Catalog format: GNU --> install in $(datadir) | ||
45 | dnl Catalog extension: .mo after installation, .gmo in source tree | ||
46 | dnl 3) No internationalization, always use English msgid. | ||
47 | dnl Catalog format: none | ||
48 | dnl Catalog extension: none | ||
49 | dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur. | ||
50 | dnl The use of .gmo is historical (it was needed to avoid overwriting the | ||
51 | dnl GNU format catalogs when building on a platform with an X/Open gettext), | ||
52 | dnl but we keep it in order not to force irrelevant filename changes on the | ||
53 | dnl maintainers. | ||
