# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
68
# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
69
# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
70
#
71
# Of course, Automake must honor this variable whenever it calls a
72
# tool from the auxiliary directory.  The problem is that $srcdir (and
73
# therefore $ac_aux_dir as well) can be either absolute or relative,
74
# depending on how configure is run.  This is pretty annoying, since
75
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
76
# source directory, any form will work fine, but in subdirectories a
77
# relative path needs to be adjusted first.
78
#
79
# $ac_aux_dir/missing
80
#    fails when called from a subdirectory if $ac_aux_dir is relative
81
# $top_srcdir/$ac_aux_dir/missing
82
#    fails if $ac_aux_dir is absolute,
83
#    fails when called from a subdirectory in a VPATH build with
84
#          a relative $ac_aux_dir
85
#
86
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
87
# are both prefixed by $srcdir.  In an in-source build this is usually
88
# harmless because $srcdir is '.', but things will broke when you
89
# start a VPATH build or use an absolute $srcdir.
90
#
91
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
92
# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
93
#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
94
# and then we would define $MISSING as
95
#   MISSING="\${SHELL} $am_aux_dir/missing"
96
# This will work as long as MISSING is not called from configure, because
97
# unfortunately $(top_srcdir) has no meaning in configure.
98
# However there are other variables, like CC, which are often used in
99
# configure, and could therefore not use this "fixed" $ac_aux_dir.
100
#
101
# Another solution, used here, is to always expand $ac_aux_dir to an
102
# absolute PATH.  The drawback is that using absolute paths prevent a
103
# configured tree to be moved without reconfiguration.
