The 26*440a403fSchristosdnl default (if it is not specified or empty) is 'no-libtool'. 27*440a403fSchristosdnl INTLSYMBOL should be 'external' for packages with no intl directory, 28*440a403fSchristosdnl and 'no-libtool' or 'use-libtool' for packages with an intl directory. 29*440a403fSchristosdnl If INTLSYMBOL is 'use-libtool', then a libtool library 30*440a403fSchristosdnl $(top_builddir)/intl/libintl.la will be created (shared and/or static, 31*440a403fSchristosdnl depending on --{enable,disable}-{shared,static} and on the presence of 32*440a403fSchristosdnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library 33*440a403fSchristosdnl $(top_builddir)/intl/libintl.a will be created. 34*440a403fSchristosdnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext 35*440a403fSchristosdnl implementations (in libc or libintl) without the ngettext() function 36*440a403fSchristosdnl will be ignored. If NEEDSYMBOL is specified and is 37*440a403fSchristosdnl 'need-formatstring-macros', then GNU gettext implementations that don't 38*440a403fSchristosdnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored. 39*440a403fSchristosdnl INTLDIR is used to find the intl libraries. If empty, 40*440a403fSchristosdnl the value `$(top_builddir)/intl/' is used. 41*440a403fSchristosdnl 42*440a403fSchristosdnl The result of the configuration is one of three cases: 43*440a403fSchristosdnl 1) GNU gettext, as included in the intl subdirectory, will be compiled 44*440a403fSchristosdnl and used. 45*440a403fSchristosdnl Catalog format: GNU --> install in $(datadir) 46*440a403fSchristosdnl Catalog extension: .mo after installation, .gmo in source tree 47*440a403fSchristosdnl 2) GNU gettext has been found in the system's C library. 48*440a403fSchristosdnl Catalog format: GNU --> install in $(datadir) 49*440a403fSchristosdnl Catalog extension: .mo after installation, .gmo in source tree 50*440a403fSchristosdnl 3) No internationalization, always use English msgid. 51*440a403fSchristosdnl Catalog format: none 52*440a403fSchristosdnl Catalog extension: none 53*440a403fSchristosdnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur. 54*440a403fSchristosdnl The use of .gmo is historical (it was needed to avoid overwriting the 55*440a403fSchristosdnl GNU format catalogs when building on a platform with an X/Open gettext), 56*440a403fSchristosdnl but we keep it in order not to force irrelevant filename changes on the 57*440a403fSchristosdnl maintainers. 58*440a403fSchristosdnl 59*440a403fSchristosAC_DEFUN([AM_GNU_GETTEXT], 60*440a403fSchristos[ 61*440a403fSchristos dnl Argument checking. 62*440a403fSchristos ifelse([$1], [], , [ifelse([$1], [external], , [ifelse([$1], [no-libtool], , [ifelse([$1], [use-libtool], , 63*440a403fSchristos [errprint([ERROR: invalid first argument to AM_GNU_GETTEXT 64*440a403fSchristos])])])])]) 65*440a403fSchristos ifelse([$2], [], , [ifelse([$2], [need-ngettext], , [ifelse([$2], [need-formatstring-macros], , 66*440a403fSchristos [errprint([ERROR: invalid second argument to AM_GNU_GETTEXT 67*440a403fSchristos])])])]) 68*440a403fSchristos define(gt_included_intl, ifelse([$1], [external], [no], [yes])) 69*440a403fSchristos define(gt_libtool_suffix_prefix, ifelse([$1], [use-libtool], [l], [])) 70*440a403fSchristos 71*440a403fSchristos AC_REQUIRE([AM_PO_SUBDIRS])dnl 72*440a403fSchristos ifelse(gt_included_intl, yes, [ 73*440a403fSchristos AC_REQUIRE([AM_INTL_SUBDIR])dnl 74*440a403fSchristos ]) 75*440a403fSchristos 76*440a403fSchristos dnl Prerequisites of AC_LIB_LINKFLAGS_BODY. 77*440a403fSchristos AC_REQUIRE([AC_LIB_PREPARE_PREFIX]) 78*440a403fSchristos AC_REQUIRE([AC_LIB_RPATH]) 79*440a403fSchristos 80*440a403fSchristos dnl Sometimes libintl requires libiconv, so first search for libiconv. 81*440a403fSchristos dnl Ideally we would do this search only after the 82*440a403fSchristos dnl if test "$USE_NLS" = "yes"; then 83*440a403fSchristos dnl if test "$gt_cv_func_gnugettext_libc" != "yes"; then 84*440a403fSchristos dnl tests.
