  22 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  23 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
  24 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
  25 #
  26 # Of course, Automake must honor this variable whenever it calls a
  27 # tool from the auxiliary directory.  The problem is that $srcdir (and
  28 # therefore $ac_aux_dir as well) can be either absolute or relative,
  29 # depending on how configure is run.  This is pretty annoying, since
  30 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  31 # source directory, any form will work fine, but in subdirectories a
  32 # relative path needs to be adjusted first.
  33 #
  34 # $ac_aux_dir/missing
  35 #    fails when called from a subdirectory if $ac_aux_dir is relative
  36 # $top_srcdir/$ac_aux_dir/missing
  37 #    fails if $ac_aux_dir is absolute,
  38 #    fails when called from a subdirectory in a VPATH build with
  39 #          a relative $ac_aux_dir
  40 #
  41 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  42 # are both prefixed by $srcdir.  In an in-source build this is usually
  43 # harmless because $srcdir is `.', but things will broke when you
  44 # start a VPATH build or use an absolute $srcdir.
  45 #
  46 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  47 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
  48 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  49 # and then we would define $MISSING as
  50 #   MISSING="\${SHELL} $am_aux_dir/missing"
  51 # This will work as long as MISSING is not called from configure, because
  52 # unfortunately $(top_srcdir) has no meaning in configure.
  53 # However there are other variables, like CC, which are often used in
  54 # configure, and could therefore not use this "fixed" $ac_aux_dir.
  55 #
  56 # Another solution, used here, is to always expand $ac_aux_dir to an
  57 # absolute PATH.  The drawback is that using absolute paths prevent a
  58 # configured tree to be moved without reconfiguration.
