614 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
615 # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
616 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
618 # Of course, Automake must honor this variable whenever it calls a
619 # tool from the auxiliary directory. The problem is that $srcdir (and
620 # therefore $ac_aux_dir as well) can be either absolute or relative,
621 # depending on how configure is run. This is pretty annoying, since
622 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
623 # source directory, any form will work fine, but in subdirectories a
624 # relative path needs to be adjusted first.
626 # $ac_aux_dir/missing
627 # fails when called from a subdirectory if $ac_aux_dir is relative
628 # $top_srcdir/$ac_aux_dir/missing
629 # fails if $ac_aux_dir is absolute,
630 # fails when called from a subdirectory in a VPATH build with
631 # a relative $ac_aux_dir
633 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
634 # are both prefixed by $srcdir. In an in-source build this is usually
635 # harmless because $srcdir is '.', but things will broke when you
636 # start a VPATH build or use an absolute $srcdir.
638 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
639 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
640 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
641 # and then we would define $MISSING as
642 # MISSING="\${SHELL} $am_aux_dir/missing"
643 # This will work as long as MISSING is not called from configure, because
644 # unfortunately $(top_srcdir) has no meaning in configure.
645 # However there are other variables, like CC, which are often used in
646 # configure, and could therefore not use this "fixed" $ac_aux_dir.
648 # Another solution, used here, is to always expand $ac_aux_dir to an
649 # absolute PATH. The drawback is that using absolute paths prevent a
