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. |

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

88 | dnl - Control the expansions in more detail using AC_PROVIDE_IFELSE. |

433 | dnl intl/plural.c is generated from intl/plural.y. It requires bison, |
434 | dnl because plural.y uses bison specific features. It requires at least |
435 | dnl bison-1.26 because earlier versions generate a plural.c that doesn't |
436 | dnl compile. |
437 | dnl bison is only needed for the maintainer (who touches plural.y). But in |
438 | dnl order to avoid separate Makefiles or --enable-maintainer-mode, we put |
439 | dnl the rule in general Makefile. Now, some people carelessly touch the |
440 | dnl files or have a broken "make" program, hence the plural.c rule will |
441 | dnl sometimes fire. To avoid an error, defines BISON to ":" if it is not |
442 | dnl present or too old. |
