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

97 | dnl the configure script would need to contain the same shell code | |
