401 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets

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