145 dnl Macro to add for using GNU gettext.
147 dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
148 dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
149 dnl default (if it is not specified or empty) is 'no-libtool'.
150 dnl INTLSYMBOL should be 'external' for packages with no intl directory,
151 dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
152 dnl If INTLSYMBOL is 'use-libtool', then a libtool library
153 dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
154 dnl depending on --{enable,disable}-{shared,static} and on the presence of
155 dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
156 dnl $(top_builddir)/intl/libintl.a will be created.
157 dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
158 dnl implementations (in libc or libintl) without the ngettext() function
159 dnl will be ignored. If NEEDSYMBOL is specified and is
160 dnl 'need-formatstring-macros', then GNU gettext implementations that don't
161 dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
162 dnl INTLDIR is used to find the intl libraries. If empty,
163 dnl the value `$(top_builddir)/intl/' is used.
164 dnl
165 dnl The result of the configuration is one of three cases:
166 dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
167 dnl and used.
168 dnl Catalog format: GNU --> install in $(datadir)
169 dnl Catalog extension: .mo after installation, .gmo in source tree
170 dnl 2) GNU gettext has been found in the system's C library.
171 dnl Catalog format: GNU --> install in $(datadir)
172 dnl Catalog extension: .mo after installation, .gmo in source tree
173 dnl 3) No internationalization, always use English msgid.
174 dnl Catalog format: none
175 dnl Catalog extension: none
176 dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
177 dnl The use of .gmo is historical (it was needed to avoid overwriting the
178 dnl GNU format catalogs when building on a platform with an X/Open gettext),
179 dnl but we keep it in order not to force irrelevant filename changes on the
180 dnl maintainers.

4247 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
4248 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
4249 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
4250 #
4251 # Of course, Automake must honor this variable whenever it calls a
4252 # tool from the auxiliary directory. The problem is that $srcdir (and
4253 # therefore $ac_aux_dir as well) can be either absolute or relative,
4254 # depending on how configure is run. This is pretty annoying, since
4255 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
4256 # source directory, any form will work fine, but in subdirectories a
4257 # relative path needs to be adjusted first.
4258 #
4259 # $ac_aux_dir/missing
4260 # fails when called from a subdirectory if $ac_aux_dir is relative
4261 # $top_srcdir/$ac_aux_dir/missing
4262 # fails if $ac_aux_dir is absolute,
4263 # fails when called from a subdirectory in a VPATH build with
4264 # a relative $ac_aux_dir
4265 #
4266 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
4267 # are both prefixed by $srcdir. In an in-source build this is usually
4268 # harmless because $srcdir is `.', but things will broke when you
4269 # start a VPATH build or use an absolute $srcdir.
4270 #
4271 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
4272 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
4273 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
4274 # and then we would define $MISSING as
4275 # MISSING="\${SHELL} $am_aux_dir/missing"
4276 # This will work as long as MISSING is not called from configure, because
4277 # unfortunately $(top_srcdir) has no meaning in configure.
4278 # However there are other variables, like CC, which are often used in
4279 # configure, and could therefore not use this "fixed" $ac_aux_dir.
4280 #
4281 # Another solution, used here, is to always expand $ac_aux_dir to an
4282 # absolute PATH. The drawback is that using absolute paths prevent a
