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 ]) dnl Prerequisites of AC_LIB_LINKFLAGS_BODY.
