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