1.1 ohara 75: #
76: # Of course, Automake must honor this variable whenever it calls a
77: # tool from the auxiliary directory. The problem is that $srcdir (and
78: # therefore $ac_aux_dir as well) can be either absolute or relative,
79: # depending on how configure is run. This is pretty annoying, since
80: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
81: # source directory, any form will work fine, but in subdirectories a
82: # relative path needs to be adjusted first.
83: #
84: # $ac_aux_dir/missing
85: # fails when called from a subdirectory if $ac_aux_dir is relative
86: # $top_srcdir/$ac_aux_dir/missing
87: # fails if $ac_aux_dir is absolute,
88: # fails when called from a subdirectory in a VPATH build with
89: # a relative $ac_aux_dir
90: #
91: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
92: # are both prefixed by $srcdir. In an in-source build this is usually
1.8 ! noro 93: # harmless because $srcdir is `.', but things will broke when you
1.1 ohara 94: # start a VPATH build or use an absolute $srcdir.
95: #
96: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
97: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
98: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
99: # and then we would define $MISSING as
100: # MISSING="\${SHELL} $am_aux_dir/missing"
101: # This will work as long as MISSING is not called from configure, because
102: # unfortunately $(top_srcdir) has no meaning in configure.
103: # However there are other variables, like CC, which are often used in
104: # configure, and could therefore not use this "fixed" $ac_aux_dir.
105: #
106: # Another solution, used here, is to always expand $ac_aux_dir to an
107: # absolute PATH. The drawback is that using absolute paths prevent a
