854 | dnl Usage: AM_WITH_NLS([TOOLSYMBOL], [NEEDSYMBOL], [LIBDIR]). | |
855 | dnl If TOOLSYMBOL is specified and is 'use-libtool', then a libtool library | |
856 | dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static, | |
857 | dnl depending on --{enable,disable}-{shared,static} and on the presence of | |
858 | dnl AM-DISABLE-SHARED). Otherwise, a static library | |
859 | dnl $(top_builddir)/intl/libintl.a will be created. | |
860 | dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext | |
861 | dnl implementations (in libc or libintl) without the ngettext() function | |
862 | dnl will be ignored. | |
863 | dnl LIBDIR is used to find the intl libraries. If empty, | |
864 | dnl the value `$(top_builddir)/intl/' is used. | |
865 | dnl | |
866 | dnl The result of the configuration is one of three cases: | |
867 | dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled | |
868 | dnl and used. | |
869 | dnl Catalog format: GNU --> install in $(datadir) | |
870 | dnl Catalog extension: .mo after installation, .gmo in source tree | |
871 | dnl 2) GNU gettext has been found in the system's C library. | |
872 | dnl Catalog format: GNU --> install in $(datadir) | |
873 | dnl Catalog extension: .mo after installation, .gmo in source tree | |
874 | dnl 3) No internationalization, always use English msgid. | |
875 | dnl Catalog format: none | |
876 | dnl Catalog extension: none | |
877 | dnl The use of .gmo is historical (it was needed to avoid overwriting the | |
878 | dnl GNU format catalogs when building on a platform with an X/Open gettext), | |
