66: # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
67: # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
68: # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
69: #
70: # Of course, Automake must honor this variable whenever it calls a
71: # tool from the auxiliary directory. The problem is that $srcdir (and
72: # therefore $ac_aux_dir as well) can be either absolute or relative,
73: # depending on how configure is run. This is pretty annoying, since
74: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
75: # source directory, any form will work fine, but in subdirectories a
76: # relative path needs to be adjusted first.
77: #
78: # $ac_aux_dir/missing
79: # fails when called from a subdirectory if $ac_aux_dir is relative
80: # $top_srcdir/$ac_aux_dir/missing
81: # fails if $ac_aux_dir is absolute,
82: # fails when called from a subdirectory in a VPATH build with
83: # a relative $ac_aux_dir
84: #
85: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
86: # are both prefixed by $srcdir. In an in-source build this is usually
87: # harmless because $srcdir is '.', but things will broke when you
88: # start a VPATH build or use an absolute $srcdir.
89: #
90: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
91: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
92: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
93: # and then we would define $MISSING as
94: # MISSING="\${SHELL} $am_aux_dir/missing"
95: # This will work as long as MISSING is not called from configure, because
96: # unfortunately $(top_srcdir) has no meaning in configure.
97: # However there are other variables, like CC, which are often used in
98: # configure, and could therefore not use this "fixed" $ac_aux_dir.
99: #
100: # Another solution, used here, is to always expand $ac_aux_dir to an
101: # absolute PATH. The drawback is that using absolute paths prevent a
