dnl Macro to add for using GNU gettext. |
|
21 |
||
22 |
dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]). |
|
23 |
dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The |
|
24 |
dnl default (if it is not specified or empty) is 'no-libtool'. |
|
25 |
dnl INTLSYMBOL should be 'external' for packages with no intl directory, |
|
26 |
dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory. |
|
27 |
dnl If INTLSYMBOL is 'use-libtool', then a libtool library |
|
28 |
dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static, |
|
29 |
dnl depending on --{enable,disable}-{shared,static} and on the presence of |
|
30 |
dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library |
|
31 |
dnl $(top_builddir)/intl/libintl.a will be created. |
|
32 |
dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext |
|
33 |
dnl implementations (in libc or libintl) without the ngettext() function |
|
34 |
dnl will be ignored. If NEEDSYMBOL is specified and is |
|
35 |
dnl 'need-formatstring-macros', then GNU gettext implementations that don't |
|
36 |
dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
|
|
37 |
dnl INTLDIR is used to find the intl libraries. If empty,
|
|
38 |
dnl the value `$(top_builddir)/intl/' is used. |
|
39 |
dnl
|
|
40 |
dnl The result of the configuration is one of three cases: |
|
41 |
dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled |
|
42 |
dnl and used. |
|
43 |
dnl Catalog format: GNU --> install in $(datadir) |
|
44 |
dnl Catalog extension: .mo after installation, .gmo in source tree |
|
45 |
dnl 2) GNU gettext has been found in the system's C library. |
|
46 |
dnl Catalog format: GNU --> install in $(datadir)
|
|
47 |
dnl Catalog extension: .mo after installation, .gmo in source tree
|
|
48 |
dnl 3) No internationalization, always use English msgid.
|
|
49 |
dnl Catalog format: none
|
|
50 |
dnl Catalog extension: none
|
|
51 |
dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur. |
|
52 |
dnl The use of .gmo is historical (it was needed to avoid overwriting the
|
|
53 |
dnl GNU format catalogs when building on a platform with an X/Open gettext),
|
|
54 |
dnl but we keep it in order not to force irrelevant filename changes on the
|
|
55 |
dnl maintainers.
