813 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
814 # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
815 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
817 # Of course, Automake must honor this variable whenever it calls a
818 # tool from the auxiliary directory. The problem is that $srcdir (and
819 # therefore $ac_aux_dir as well) can be either absolute or relative,
820 # depending on how configure is run. This is pretty annoying, since
821 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
822 # source directory, any form will work fine, but in subdirectories a
823 # relative path needs to be adjusted first.
825 # $ac_aux_dir/missing
826 # fails when called from a subdirectory if $ac_aux_dir is relative
827 # $top_srcdir/$ac_aux_dir/missing
828 # fails if $ac_aux_dir is absolute,
829 # fails when called from a subdirectory in a VPATH build with
830 # a relative $ac_aux_dir
832 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
833 # are both prefixed by $srcdir. In an in-source build this is usually
834 # harmless because $srcdir is '.', but things will broke when you
835 # start a VPATH build or use an absolute $srcdir.
837 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
838 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
839 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
840 # and then we would define $MISSING as
841 # MISSING="\${SHELL} $am_aux_dir/missing"
842 # This will work as long as MISSING is not called from configure, because
843 # unfortunately $(top_srcdir) has no meaning in configure.
844 # However there are other variables, like CC, which are often used in
845 # configure, and could therefore not use this "fixed" $ac_aux_dir.
