397: #
398: # Of course, Automake must honor this variable whenever it calls a
399: # tool from the auxiliary directory. The problem is that $srcdir (and
400: # therefore $ac_aux_dir as well) can be either absolute or relative,
401: # depending on how configure is run. This is pretty annoying, since
402: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
403: # source directory, any form will work fine, but in subdirectories a
404: # relative path needs to be adjusted first.
405: #
406: # $ac_aux_dir/missing
407: # fails when called from a subdirectory if $ac_aux_dir is relative
408: # $top_srcdir/$ac_aux_dir/missing
409: # fails if $ac_aux_dir is absolute,
410: # fails when called from a subdirectory in a VPATH build with
411: # a relative $ac_aux_dir
412: #
413: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
414: # are both prefixed by $srcdir. In an in-source build this is usually
415: # harmless because $srcdir is `.', but things will broke when you
416: # start a VPATH build or use an absolute $srcdir.
417: #
418: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
419: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
420: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
421: # and then we would define $MISSING as
422: # MISSING="\${SHELL} $am_aux_dir/missing"
423: # This will work as long as MISSING is not called from configure, because
424: # unfortunately $(top_srcdir) has no meaning in configure.
425: # However there are other variables, like CC, which are often used in
426: # configure, and could therefore not use this "fixed" $ac_aux_dir.
427: #
428: # Another solution, used here, is to always expand $ac_aux_dir to an
