1931 | ||
1932 | dnl Macro to add for using GNU gettext. | |
1933 | ||
1934 | dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]). | |
1935 | dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The | |
1936 | dnl default (if it is not specified or empty) is 'no-libtool'. | |
1937 | dnl INTLSYMBOL should be 'external' for packages with no intl directory, | |
1938 | dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory. | |
1939 | dnl If INTLSYMBOL is 'use-libtool', then a libtool library | |
1940 | dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static, | |
1941 | dnl depending on --{enable,disable}-{shared,static} and on the presence of | |
1942 | dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library | |
1943 | dnl $(top_builddir)/intl/libintl.a will be created. | |
1944 | dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext | |
1945 | dnl implementations (in libc or libintl) without the ngettext() function | |
1946 | dnl will be ignored. If NEEDSYMBOL is specified and is | |
1947 | dnl 'need-formatstring-macros', then GNU gettext implementations that don't | |
1948 | dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored. | |
1949 | dnl INTLDIR is used to find the intl libraries. If empty, | |
1950 | dnl the value `$(top_builddir)/intl/' is used. | |
1951 | dnl | |
1952 | dnl The result of the configuration is one of three cases: | |
1953 | dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled | |
1954 | dnl and used. | |
1955 | dnl Catalog format: GNU --> install in $(datadir) | |
1956 | dnl Catalog extension: .mo after installation, .gmo in source tree | |
1957 | dnl 2) GNU gettext has been found in the system's C library. | |
1958 | dnl Catalog format: GNU --> install in $(datadir) | |
1959 | dnl Catalog extension: .mo after installation, .gmo in source tree | |
1960 | dnl 3) No internationalization, always use English msgid. | |
1961 | dnl Catalog format: none | |
1962 | dnl Catalog extension: none | |
1963 | dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur. | |
1964 | dnl The use of .gmo is historical (it was needed to avoid overwriting the | |
1965 | dnl GNU format catalogs when building on a platform with an X/Open gettext), | |
1966 | dnl but we keep it in order not to force irrelevant filename changes on the | |
1967 | dnl maintainers. | |
