The 24dnl default (if it is not specified or empty) is 'no-libtool'. 25dnl INTLSYMBOL should be 'external' for packages with no intl directory, 26dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory. 27dnl If INTLSYMBOL is 'use-libtool', then a libtool library 28dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static, 29dnl depending on --{enable,disable}-{shared,static} and on the presence of 30dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library 31dnl $(top_builddir)/intl/libintl.a will be created. 32dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext 33dnl implementations (in libc or libintl) without the ngettext() function 34dnl will be ignored. If NEEDSYMBOL is specified and is 35dnl 'need-formatstring-macros', then GNU gettext implementations that don't 36dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored. 37dnl INTLDIR is used to find the intl libraries. If empty, 38dnl the value `$(top_builddir)/intl/' is used. 39dnl 40dnl The result of the configuration is one of three cases: 41dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled 42dnl and used. 43dnl Catalog format: GNU --> install in $(datadir) 44dnl Catalog extension: .mo after installation, .gmo in source tree 45dnl 2) GNU gettext has been found in the system's C library. 46dnl Catalog format: GNU --> install in $(datadir) 47dnl Catalog extension: .mo after installation, .gmo in source tree 48dnl 3) No internationalization, always use English msgid. 49dnl Catalog format: none 50dnl Catalog extension: none 51dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur. 52dnl The use of .gmo is historical (it was needed to avoid overwriting the 53dnl GNU format catalogs when building on a platform with an X/Open gettext), 54dnl but we keep it in order not to force irrelevant filename changes on the 55dnl maintainers. 56dnl 57AC_DEFUN([AM_GNU_GETTEXT], 58[ 59 dnl Argument checking. 60 ifelse([$1], [], , [ifelse([$1], [external], , [ifelse([$1], [no-libtool], , [ifelse([$1], [use-libtool], , 61 [errprint([ERROR: invalid first argument to AM_GNU_GETTEXT 62])])])])]) 63 ifelse([$2], [], , [ifelse([$2], [need-ngettext], , [ifelse([$2], [need-formatstring-macros], , 64 [errprint([ERROR: invalid second argument to AM_GNU_GETTEXT 65])])])]) 66 define([gt_included_intl], ifelse([$1], [external], [no], [yes])) 67 define([gt_libtool_suffix_prefix], ifelse([$1], [use-libtool], [l], [])) 68 69 AC_REQUIRE([AM_PO_SUBDIRS])dnl 70 ifelse(gt_included_intl, yes, [ 71 AC_REQUIRE([AM_INTL_SUBDIR])dnl 72 ]) 73 74 dnl Prerequisites of AC_LIB_LINKFLAGS_BODY. 75 AC_REQUIRE([AC_LIB_PREPARE_PREFIX]) 76 AC_REQUIRE([AC_LIB_RPATH]) 77 78 dnl Sometimes libintl requires libiconv, so first search for libiconv. 79 dnl Ideally we would do this search only after the 80 dnl if test "$USE_NLS" = "yes"; then 81 dnl if test "$gt_cv_func_gnugettext_libc" != "yes"; then 82 dnl tests.
