The +dnl default (if it is not specified or empty) is 'no-libtool'. +dnl INTLSYMBOL should be 'external' for packages with no intl directory, +dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory. +dnl If INTLSYMBOL is 'use-libtool', then a libtool library +dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static, +dnl depending on --{enable,disable}-{shared,static} and on the presence of +dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library +dnl $(top_builddir)/intl/libintl.a will be created. +dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext +dnl implementations (in libc or libintl) without the ngettext() function +dnl will be ignored. If NEEDSYMBOL is specified and is +dnl 'need-formatstring-macros', then GNU gettext implementations that don't +dnl support the ISO C 99 formatstring macros will be ignored. +dnl INTLDIR is used to find the intl libraries. If empty, +dnl the value `$(top_builddir)/intl/' is used. +dnl +dnl The result of the configuration is one of three cases: +dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled +dnl and used. +dnl Catalog format: GNU --> install in $(datadir) +dnl Catalog extension: .mo after installation, .gmo in source tree +dnl 2) GNU gettext has been found in the system's C library. +dnl Catalog format: GNU --> install in $(datadir) +dnl Catalog extension: .mo after installation, .gmo in source tree +dnl 3) No internationalization, always use English msgid. +dnl Catalog format: none +dnl Catalog extension: none +dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur. +dnl The use of .gmo is historical (it was needed to avoid overwriting the +dnl GNU format catalogs when building on a platform with an X/Open gettext), +dnl but we keep it in order not to force irrelevant filename changes on the +dnl maintainers. +dnl +AC_DEFUN([AM_GNU_GETTEXT], +[ + dnl Argument checking. + ifelse([$1], [], , [ifelse([$1], [external], , [ifelse([$1], [no-libtool], , [ifelse([$1], [use-libtool], , + [errprint([ERROR: invalid first argument to AM_GNU_GETTEXT +])])])])]) + ifelse([$2], [], , [ifelse([$2], [need-ngettext], , [ifelse([$2], [need-formatstring-macros], , + [errprint([ERROR: invalid second argument to AM_GNU_GETTEXT +])])])]) + define([gt_included_intl], ifelse([$1], [external], [no], [yes])) + define([gt_libtool_suffix_prefix], ifelse([$1], [use-libtool], [l], [])) + + AC_REQUIRE([AM_PO_SUBDIRS])dnl + ifelse(gt_included_intl, yes, [ + AC_REQUIRE([AM_INTL_SUBDIR])dnl + ]) - USE_INCLUDED_LIBINTL=no + dnl Prerequisites of AC_LIB_LINKFLAGS_BODY. + AC_REQUIRE([AC_LIB_PREPARE_PREFIX]) + AC_REQUIRE([AC_LIB_RPATH]) + + dnl Sometimes libintl requires libiconv, so first search for libiconv. + dnl Ideally we would do this search only after the + dnl if test "$USE_NLS" = "yes"; then + dnl if test "$gt_cv_func_gnugettext_libc" != "yes"; then + dnl tests.
