61# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
62# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
63# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
64#
65# Of course, Automake must honor this variable whenever it calls a
66# tool from the auxiliary directory. The problem is that $srcdir (and
67# therefore $ac_aux_dir as well) can be either absolute or relative,
68# depending on how configure is run. This is pretty annoying, since
69# it makes $ac_aux_dir quite unusable in subdirectories: in the top
70# source directory, any form will work fine, but in subdirectories a
71# relative path needs to be adjusted first.
72#
73# $ac_aux_dir/missing
74# fails when called from a subdirectory if $ac_aux_dir is relative
75# $top_srcdir/$ac_aux_dir/missing
76# fails if $ac_aux_dir is absolute,
77# fails when called from a subdirectory in a VPATH build with
78# a relative $ac_aux_dir
79#
80# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
81# are both prefixed by $srcdir. In an in-source build this is usually
82# harmless because $srcdir is `.', but things will broke when you
83# start a VPATH build or use an absolute $srcdir.
84#
85# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
86# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
87# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
88# and then we would define $MISSING as
89# MISSING="\${SHELL} $am_aux_dir/missing"
90# This will work as long as MISSING is not called from configure, because
91# unfortunately $(top_srcdir) has no meaning in configure.
92# However there are other variables, like CC, which are often used in
93# configure, and could therefore not use this "fixed" $ac_aux_dir.
94#
95# Another solution, used here, is to always expand $ac_aux_dir to an
96# absolute PATH. The drawback is that using absolute paths prevent a
97# configured tree to be moved without reconfiguration.
