227: #
228: # Of course, Automake must honor this variable whenever it calls a
229: # tool from the auxiliary directory. The problem is that $srcdir (and
230: # therefore $ac_aux_dir as well) can be either absolute or relative,
231: # depending on how configure is run. This is pretty annoying, since
232: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
233: # source directory, any form will work fine, but in subdirectories a
234: # relative path needs to be adjusted first.
235: #
236: # $ac_aux_dir/missing
237: # fails when called from a subdirectory if $ac_aux_dir is relative

239: # fails if $ac_aux_dir is absolute,
240: # fails when called from a subdirectory in a VPATH build with
241: # a relative $ac_aux_dir
242: #
243: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
244: # are both prefixed by $srcdir. In an in-source build this is usually
245: # harmless because $srcdir is `.', but things will broke when you
246: # start a VPATH build or use an absolute $srcdir.
247: #
248: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
249: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
250: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
251: # and then we would define $MISSING as
252: # MISSING="\${SHELL} $am_aux_dir/missing"

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