# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
42
# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
43
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
44
#
45
# Of course, Automake must honor this variable whenever it calls a
46
# tool from the auxiliary directory.  The problem is that $srcdir (and
47
# therefore $ac_aux_dir as well) can be either absolute or relative,
48
# depending on how configure is run.  This is pretty annoying, since
49
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
50
# source directory, any form will work fine, but in subdirectories a
51
# relative path needs to be adjusted first.
52
#
53
# $ac_aux_dir/missing
54
#    fails when called from a subdirectory if $ac_aux_dir is relative
55
# $top_srcdir/$ac_aux_dir/missing
56
#    fails if $ac_aux_dir is absolute,
57
#    fails when called from a subdirectory in a VPATH build with
58
#          a relative $ac_aux_dir
59
#
60
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
61
# are both prefixed by $srcdir.  In an in-source build this is usually
62
# harmless because $srcdir is `.', but things will broke when you
63
# start a VPATH build or use an absolute $srcdir.
64
#
65
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
66
# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
67
#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
68
# and then we would define $MISSING as
69
#   MISSING="\${SHELL} $am_aux_dir/missing"
70
# This will work as long as MISSING is not called from configure, because
71
# unfortunately $(top_srcdir) has no meaning in configure.
72
# However there are other variables, like CC, which are often used in
73
# configure, and could therefore not use this "fixed" $ac_aux_dir.
74
#
75
# Another solution, used here, is to always expand $ac_aux_dir to an
76
# absolute PATH.  The drawback is that using absolute paths prevent a
77
# configured tree to be moved without reconfiguration.
