409 # Of course, Automake must honor this variable whenever it calls a
410 # tool from the auxiliary directory. The problem is that $srcdir (and
411 # therefore $ac_aux_dir as well) can be either absolute or relative,
412 # depending on how configure is run. This is pretty annoying, since
413 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
414 # source directory, any form will work fine, but in subdirectories a
415 # relative path needs to be adjusted first.
417 # $ac_aux_dir/missing

420 # fails if $ac_aux_dir is absolute,
421 # fails when called from a subdirectory in a VPATH build with
422 # a relative $ac_aux_dir
424 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
425 # are both prefixed by $srcdir. In an in-source build this is usually
426 # harmless because $srcdir is '.', but things will broke when you
427 # start a VPATH build or use an absolute $srcdir.
429 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
430 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
431 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
432 # and then we would define $MISSING as
433 # MISSING="\${SHELL} $am_aux_dir/missing"
434 # This will work as long as MISSING is not called from configure, because
435 # unfortunately $(top_srcdir) has no meaning in configure.
436 # However there are other variables, like CC, which are often used in
437 # configure, and could therefore not use this "fixed" $ac_aux_dir.
