67     # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
68 michael 1373 # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
69     # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
70 michael 912 #
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 michael 1373 # harmless because $srcdir is '.', but things will broke when you
89 michael 912 # 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.
