22
dnl Macro to add for using GNU gettext.
23

    
24
dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
25
dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
26
dnl    default (if it is not specified or empty) is 'no-libtool'.
27
dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
28
dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
29
dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
30
dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
31
dnl    depending on --{enable,disable}-{shared,static} and on the presence of
32
dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
33
dnl    $(top_builddir)/intl/libintl.a will be created.
34
dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
35
dnl    implementations (in libc or libintl) without the ngettext() function
36
dnl    will be ignored.  If NEEDSYMBOL is specified and is
37
dnl    'need-formatstring-macros', then GNU gettext implementations that don't
38
dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
39
dnl INTLDIR is used to find the intl libraries.  If empty,
40
dnl    the value `$(top_builddir)/intl/' is used.
41
dnl
42
dnl The result of the configuration is one of three cases:
43
dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
44
dnl    and used.
45
dnl    Catalog format: GNU --> install in $(datadir)
46
dnl    Catalog extension: .mo after installation, .gmo in source tree
47
dnl 2) GNU gettext has been found in the system's C library.
48
dnl    Catalog format: GNU --> install in $(datadir)
49
dnl    Catalog extension: .mo after installation, .gmo in source tree
50
dnl 3) No internationalization, always use English msgid.
51
dnl    Catalog format: none
52
dnl    Catalog extension: none
53
dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
54
dnl The use of .gmo is historical (it was needed to avoid overwriting the
55
dnl GNU format catalogs when building on a platform with an X/Open gettext),
56
dnl but we keep it in order not to force irrelevant filename changes on the
57
dnl maintainers.
