1.1 misho 130: #
131: # Of course, Automake must honor this variable whenever it calls a
132: # tool from the auxiliary directory. The problem is that $srcdir (and
133: # therefore $ac_aux_dir as well) can be either absolute or relative,
134: # depending on how configure is run. This is pretty annoying, since
135: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
136: # source directory, any form will work fine, but in subdirectories a
137: # relative path needs to be adjusted first.
138: #
139: # $ac_aux_dir/missing
140: # fails when called from a subdirectory if $ac_aux_dir is relative
141: # $top_srcdir/$ac_aux_dir/missing
142: # fails if $ac_aux_dir is absolute,
143: # fails when called from a subdirectory in a VPATH build with
144: # a relative $ac_aux_dir
145: #
146: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
147: # are both prefixed by $srcdir. In an in-source build this is usually
1.1.1.2 ! misho 148: # harmless because $srcdir is '.', but things will broke when you
1.1 misho 149: # start a VPATH build or use an absolute $srcdir.
150: #
151: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
152: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
153: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
154: # and then we would define $MISSING as
155: # MISSING="\${SHELL} $am_aux_dir/missing"
156: # This will work as long as MISSING is not called from configure, because
157: # unfortunately $(top_srcdir) has no meaning in configure.
158: # However there are other variables, like CC, which are often used in
159: # configure, and could therefore not use this "fixed" $ac_aux_dir.
160: #
161: # Another solution, used here, is to always expand $ac_aux_dir to an
162: # absolute PATH. The drawback is that using absolute paths prevent a
163: # configured tree to be moved without reconfiguration.
