64: # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
65: # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
66: # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
67: #
68: # Of course, Automake must honor this variable whenever it calls a
69: # tool from the auxiliary directory. The problem is that $srcdir (and
70: # therefore $ac_aux_dir as well) can be either absolute or relative,
71: # depending on how configure is run. This is pretty annoying, since
72: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
73: # source directory, any form will work fine, but in subdirectories a
74: # relative path needs to be adjusted first.
75: #
76: # $ac_aux_dir/missing
77: # fails when called from a subdirectory if $ac_aux_dir is relative
78: # $top_srcdir/$ac_aux_dir/missing
79: # fails if $ac_aux_dir is absolute,
80: # fails when called from a subdirectory in a VPATH build with
81: # a relative $ac_aux_dir
82: #
83: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
84: # are both prefixed by $srcdir. In an in-source build this is usually
85: # harmless because $srcdir is `.', but things will broke when you
86: # start a VPATH build or use an absolute $srcdir.
87: #
88: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
89: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
90: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
91: # and then we would define $MISSING as
92: # MISSING="\${SHELL} $am_aux_dir/missing"
93: # This will work as long as MISSING is not called from configure, because
94: # unfortunately $(top_srcdir) has no meaning in configure.
95: # However there are other variables, like CC, which are often used in
96: # configure, and could therefore not use this "fixed" $ac_aux_dir.
97: #
98: # Another solution, used here, is to always expand $ac_aux_dir to an
99: # absolute PATH. The drawback is that using absolute paths prevent a
100: # configured tree to be moved without reconfiguration.
