  235. # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  236. # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
  237. # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
  238. #
  239. # Of course, Automake must honor this variable whenever it calls a
  240. # tool from the auxiliary directory. The problem is that $srcdir (and
  241. # therefore $ac_aux_dir as well) can be either absolute or relative,
  242. # depending on how configure is run. This is pretty annoying, since
  243. # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  244. # source directory, any form will work fine, but in subdirectories a
  245. # relative path needs to be adjusted first.
  246. #
  247. # $ac_aux_dir/missing
  248. # fails when called from a subdirectory if $ac_aux_dir is relative
  249. # $top_srcdir/$ac_aux_dir/missing
  250. # fails if $ac_aux_dir is absolute,
  251. # fails when called from a subdirectory in a VPATH build with
  252. # a relative $ac_aux_dir
  253. #
  254. # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  255. # are both prefixed by $srcdir. In an in-source build this is usually
  256. # harmless because $srcdir is '.', but things will broke when you
  257. # start a VPATH build or use an absolute $srcdir.
  258. #
  259. # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  260. # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
  261. # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  262. # and then we would define $MISSING as
  263. # MISSING="\${SHELL} $am_aux_dir/missing"
  264. # This will work as long as MISSING is not called from configure, because
  265. # unfortunately $(top_srcdir) has no meaning in configure.
  266. # However there are other variables, like CC, which are often used in
  267. # configure, and could therefore not use this "fixed" $ac_aux_dir.
  268. #
  269. # Another solution, used here, is to always expand $ac_aux_dir to an
  270. # absolute PATH. The drawback is that using absolute paths prevent a
