  505. # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  506. # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
  507. # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
  508. #
  509. # Of course, Automake must honor this variable whenever it calls a
  510. # tool from the auxiliary directory. The problem is that $srcdir (and
  511. # therefore $ac_aux_dir as well) can be either absolute or relative,
  512. # depending on how configure is run. This is pretty annoying, since
  513. # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  514. # source directory, any form will work fine, but in subdirectories a
  515. # relative path needs to be adjusted first.
  516. #
  517. # $ac_aux_dir/missing
  518. # fails when called from a subdirectory if $ac_aux_dir is relative
  519. # $top_srcdir/$ac_aux_dir/missing
  520. # fails if $ac_aux_dir is absolute,
  521. # fails when called from a subdirectory in a VPATH build with
  522. # a relative $ac_aux_dir
  523. #
  524. # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  525. # are both prefixed by $srcdir. In an in-source build this is usually
  526. # harmless because $srcdir is '.', but things will broke when you
  527. # start a VPATH build or use an absolute $srcdir.
  528. #
  529. # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  530. # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
  531. # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  532. # and then we would define $MISSING as
  533. # MISSING="\${SHELL} $am_aux_dir/missing"
  534. # This will work as long as MISSING is not called from configure, because
  535. # unfortunately $(top_srcdir) has no meaning in configure.
  536. # However there are other variables, like CC, which are often used in
  537. # configure, and could therefore not use this "fixed" $ac_aux_dir.
  538. #
  539. # Another solution, used here, is to always expand $ac_aux_dir to an
  540. # absolute PATH. The drawback is that using absolute paths prevent a
