250: #
251: # Of course, Automake must honor this variable whenever it calls a
252: # tool from the auxiliary directory. The problem is that $srcdir (and
253: # therefore $ac_aux_dir as well) can be either absolute or relative,
254: # depending on how configure is run. This is pretty annoying, since
255: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
256: # source directory, any form will work fine, but in subdirectories a
257: # relative path needs to be adjusted first.

262: # fails if $ac_aux_dir is absolute,
263: # fails when called from a subdirectory in a VPATH build with
264: # a relative $ac_aux_dir
265: #
266: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
267: # are both prefixed by $srcdir. In an in-source build this is usually
268: # harmless because $srcdir is `.', but things will broke when you
269: # start a VPATH build or use an absolute $srcdir.
270: #
271: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
272: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
273: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
274: # and then we would define $MISSING as
275: # MISSING="\${SHELL} $am_aux_dir/missing"
276: # This will work as long as MISSING is not called from configure, because
277: # unfortunately $(top_srcdir) has no meaning in configure.
278: # However there are other variables, like CC, which are often used in
279: # configure, and could therefore not use this "fixed" $ac_aux_dir.
280: #
281: # Another solution, used here, is to always expand $ac_aux_dir to an
