  365. #
  366. # Of course, Automake must honor this variable whenever it calls a

  368. # therefore $ac_aux_dir as well) can be either absolute or relative,
  369. # depending on how configure is run.  This is pretty annoying, since
  370. # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  371. # source directory, any form will work fine, but in subdirectories a
  372. # relative path needs to be adjusted first.

  378. #    fails when called from a subdirectory in a VPATH build with
  379. #          a relative $ac_aux_dir
  380. #
  381. # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  382. # are both prefixed by $srcdir.  In an in-source build this is usually
  383. # harmless because $srcdir is '.', but things will broke when you
  384. # start a VPATH build or use an absolute $srcdir.
  385. #
  386. # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  387. # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
  388. #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`

  394. # configure, and could therefore not use this "fixed" $ac_aux_dir.
