22# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
23# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
24# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
25#
26# Of course, Automake must honor this variable whenever it calls a
27# tool from the auxiliary directory. The problem is that $srcdir (and
28# therefore $ac_aux_dir as well) can be either absolute or relative,
29# depending on how configure is run. This is pretty annoying, since
30# it makes $ac_aux_dir quite unusable in subdirectories: in the top
31# source directory, any form will work fine, but in subdirectories a
32# relative path needs to be adjusted first.
33#
34# $ac_aux_dir/missing
35# fails when called from a subdirectory if $ac_aux_dir is relative
36# $top_srcdir/$ac_aux_dir/missing
37# fails if $ac_aux_dir is absolute,
38# fails when called from a subdirectory in a VPATH build with
39# a relative $ac_aux_dir
40#
41# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
42# are both prefixed by $srcdir. In an in-source build this is usually
43# harmless because $srcdir is `.', but things will broke when you
44# start a VPATH build or use an absolute $srcdir.
45#
46# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
47# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
48# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
49# and then we would define $MISSING as
50# MISSING="\${SHELL} $am_aux_dir/missing"
51# This will work as long as MISSING is not called from configure, because
52# unfortunately $(top_srcdir) has no meaning in configure.
53# However there are other variables, like CC, which are often used in
54# configure, and could therefore not use this "fixed" $ac_aux_dir.
55#
56# Another solution, used here, is to always expand $ac_aux_dir to an
57# absolute PATH. The drawback is that using absolute paths prevent a
58# configured tree to be moved without reconfiguration.
