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