342 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
343 # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
344 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
346 # Of course, Automake must honor this variable whenever it calls a
347 # tool from the auxiliary directory. The problem is that $srcdir (and
348 # therefore $ac_aux_dir as well) can be either absolute or relative,
349 # depending on how configure is run. This is pretty annoying, since
350 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
351 # source directory, any form will work fine, but in subdirectories a
352 # relative path needs to be adjusted first.
354 # $ac_aux_dir/missing
355 # fails when called from a subdirectory if $ac_aux_dir is relative
356 # $top_srcdir/$ac_aux_dir/missing
357 # fails if $ac_aux_dir is absolute,
358 # fails when called from a subdirectory in a VPATH build with
359 # a relative $ac_aux_dir
361 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
362 # are both prefixed by $srcdir. In an in-source build this is usually
363 # harmless because $srcdir is '.', but things will broke when you
364 # start a VPATH build or use an absolute $srcdir.
366 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
367 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
368 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
369 # and then we would define $MISSING as
370 # MISSING="\${SHELL} $am_aux_dir/missing"
371 # This will work as long as MISSING is not called from configure, because
372 # unfortunately $(top_srcdir) has no meaning in configure.
373 # However there are other variables, like CC, which are often used in
374 # configure, and could therefore not use this "fixed" $ac_aux_dir.
