21 | |||
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. | ||

83 | dnl if test "$gt_cv_func_gnugettext_libc" != "yes"; then | ||
84 | dnl tests. But if configure.in invokes AM_ICONV after AM_GNU_GETTEXT | ||
85 | dnl the configure script would need to contain the same shell code | ||
86 | dnl again, outside any 'if'. There are two solutions: | ||
87 | dnl - Invoke AM_ICONV_LINKFLAGS_BODY here, outside any 'if'. | ||
88 | dnl - Control the expansions in more detail using AC_PROVIDE_IFELSE. | ||
