259 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
260 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
261 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
262 #
263 # Of course, Automake must honor this variable whenever it calls a
264 # tool from the auxiliary directory. The problem is that $srcdir (and
265 # therefore $ac_aux_dir as well) can be either absolute or relative,
266 # depending on how configure is run. This is pretty annoying, since
267 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
268 # source directory, any form will work fine, but in subdirectories a
269 # relative path needs to be adjusted first.
270 #
271 # $ac_aux_dir/missing
272 # fails when called from a subdirectory if $ac_aux_dir is relative
273 # $top_srcdir/$ac_aux_dir/missing
274 # fails if $ac_aux_dir is absolute,
275 # fails when called from a subdirectory in a VPATH build with
276 # a relative $ac_aux_dir
277 #
278 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
279 # are both prefixed by $srcdir. In an in-source build this is usually
280 # harmless because $srcdir is `.', but things will broke when you
281 # start a VPATH build or use an absolute $srcdir.
282 #
283 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
284 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
285 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
286 # and then we would define $MISSING as
287 # MISSING="\${SHELL} $am_aux_dir/missing"
288 # This will work as long as MISSING is not called from configure, because
289 # unfortunately $(top_srcdir) has no meaning in configure.
290 # However there are other variables, like CC, which are often used in
291 # configure, and could therefore not use this "fixed" $ac_aux_dir.
292 #
293 # Another solution, used here, is to always expand $ac_aux_dir to an
294 # absolute PATH. The drawback is that using absolute paths prevent a
295 # configured tree to be moved without reconfiguration.
