cannam@127: # Of course, Automake must honor this variable whenever it calls a

cannam@127: # depending on how configure is run.  This is pretty annoying, since
cannam@127: # it makes $ac_aux_dir quite unusable in subdirectories: in the top

cannam@127: #
cannam@127: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir

cannam@127: # harmless because $srcdir is '.', but things will broke when you
cannam@127: # start a VPATH build or use an absolute $srcdir.
cannam@127: #
cannam@127: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
cannam@127: # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
cannam@127: #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`

cannam@127: # configure, and could therefore not use this "fixed" $ac_aux_dir.
