367 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
368 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
369 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
370 #
371 # Of course, Automake must honor this variable whenever it calls a
372 # tool from the auxiliary directory. The problem is that $srcdir (and
373 # therefore $ac_aux_dir as well) can be either absolute or relative,
374 # depending on how configure is run. This is pretty annoying, since
375 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
376 # source directory, any form will work fine, but in subdirectories a
377 # relative path needs to be adjusted first.
378 #
379 # $ac_aux_dir/missing
380 # fails when called from a subdirectory if $ac_aux_dir is relative
381 # $top_srcdir/$ac_aux_dir/missing
382 # fails if $ac_aux_dir is absolute,
383 # fails when called from a subdirectory in a VPATH build with
384 # a relative $ac_aux_dir
385 #
386 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
387 # are both prefixed by $srcdir. In an in-source build this is usually
388 # harmless because $srcdir is `.', but things will broke when you
389 # start a VPATH build or use an absolute $srcdir.
390 #
391 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
392 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
393 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
394 # and then we would define $MISSING as
395 # MISSING="\${SHELL} $am_aux_dir/missing"
396 # This will work as long as MISSING is not called from configure, because
397 # unfortunately $(top_srcdir) has no meaning in configure.
398 # However there are other variables, like CC, which are often used in
399 # configure, and could therefore not use this "fixed" $ac_aux_dir.
400 #
401 # Another solution, used here, is to always expand $ac_aux_dir to an
402 # absolute PATH. The drawback is that using absolute paths prevent a
403 # configured tree to be moved without reconfiguration.
