# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
349
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
350
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
351
#
352
# Of course, Automake must honor this variable whenever it calls a
353
# tool from the auxiliary directory. The problem is that $srcdir (and
354
# therefore $ac_aux_dir as well) can be either absolute or relative,
355
# depending on how configure is run. This is pretty annoying, since
356
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
357
# source directory, any form will work fine, but in subdirectories a
358
# relative path needs to be adjusted first.
359
#
360
# $ac_aux_dir/missing
361
# fails when called from a subdirectory if $ac_aux_dir is relative
362
# $top_srcdir/$ac_aux_dir/missing
363
# fails if $ac_aux_dir is absolute,
364
# fails when called from a subdirectory in a VPATH build with
365
# a relative $ac_aux_dir
366
#
367
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
368
# are both prefixed by $srcdir. In an in-source build this is usually
369
# harmless because $srcdir is `.', but things will broke when you
370
# start a VPATH build or use an absolute $srcdir.
371
#
372
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
373
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
374
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
375
# and then we would define $MISSING as
376
# MISSING="\${SHELL} $am_aux_dir/missing"
377
# This will work as long as MISSING is not called from configure, because
378
# unfortunately $(top_srcdir) has no meaning in configure.
379
# However there are other variables, like CC, which are often used in
380
# configure, and could therefore not use this "fixed" $ac_aux_dir.
381
#
382
# Another solution, used here, is to always expand $ac_aux_dir to an
383
# absolute PATH. The drawback is that using absolute paths prevent a
384
# configured tree to be moved without reconfiguration.
