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

521 # Of course, Automake must honor this variable whenever it calls a
522 # tool from the auxiliary directory. The problem is that $srcdir (and
523 # therefore $ac_aux_dir as well) can be either absolute or relative,
524 # depending on how configure is run. This is pretty annoying, since
525 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
526 # source directory, any form will work fine, but in subdirectories a
527 # relative path needs to be adjusted first.
529 # $ac_aux_dir/missing
530 # fails when called from a subdirectory if $ac_aux_dir is relative
531 # $top_srcdir/$ac_aux_dir/missing
532 # fails if $ac_aux_dir is absolute,
533 # fails when called from a subdirectory in a VPATH build with
534 # a relative $ac_aux_dir
536 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
537 # are both prefixed by $srcdir. In an in-source build this is usually
538 # harmless because $srcdir is '.', but things will broke when you
539 # start a VPATH build or use an absolute $srcdir.
541 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
542 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
543 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
544 # and then we would define $MISSING as
545 # MISSING="\${SHELL} $am_aux_dir/missing"
546 # This will work as long as MISSING is not called from configure, because
547 # unfortunately $(top_srcdir) has no meaning in configure.
548 # However there are other variables, like CC, which are often used in
549 # configure, and could therefore not use this "fixed" $ac_aux_dir.
551 # Another solution, used here, is to always expand $ac_aux_dir to an
552 # absolute PATH. The drawback is that using absolute paths prevent a
