224# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
225# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
226# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
227#
228# Of course, Automake must honor this variable whenever it calls a
229# tool from the auxiliary directory. The problem is that $srcdir (and
230# therefore $ac_aux_dir as well) can be either absolute or relative,
231# depending on how configure is run. This is pretty annoying, since
232# it makes $ac_aux_dir quite unusable in subdirectories: in the top
233# source directory, any form will work fine, but in subdirectories a
234# relative path needs to be adjusted first.
235#
236# $ac_aux_dir/missing
237# fails when called from a subdirectory if $ac_aux_dir is relative
238# $top_srcdir/$ac_aux_dir/missing
239# fails if $ac_aux_dir is absolute,
240# fails when called from a subdirectory in a VPATH build with
241# a relative $ac_aux_dir
242#
243# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
244# are both prefixed by $srcdir. In an in-source build this is usually
245# harmless because $srcdir is `.', but things will broke when you
246# start a VPATH build or use an absolute $srcdir.
247#
248# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
249# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
250# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
251# and then we would define $MISSING as
252# MISSING="\${SHELL} $am_aux_dir/missing"
253# This will work as long as MISSING is not called from configure, because
254# unfortunately $(top_srcdir) has no meaning in configure.
255# However there are other variables, like CC, which are often used in
256# configure, and could therefore not use this "fixed" $ac_aux_dir.
257#
258# Another solution, used here, is to always expand $ac_aux_dir to an
259# absolute PATH. The drawback is that using absolute paths prevent a
260# configured tree to be moved without reconfiguration.
