  114. # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
  115. #
  116. # Of course, Automake must honor this variable whenever it calls a
  117. # tool from the auxiliary directory. The problem is that $srcdir (and
  118. # therefore $ac_aux_dir as well) can be either absolute or relative,
  119. # depending on how configure is run. This is pretty annoying, since
  120. # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  121. # source directory, any form will work fine, but in subdirectories a
  122. # relative path needs to be adjusted first.
  123. #
  124. # $ac_aux_dir/missing
  125. # fails when called from a subdirectory if $ac_aux_dir is relative
  126. # $top_srcdir/$ac_aux_dir/missing
  127. # fails if $ac_aux_dir is absolute,
  128. # fails when called from a subdirectory in a VPATH build with
  129. # a relative $ac_aux_dir
  130. #
  131. # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  132. # are both prefixed by $srcdir. In an in-source build this is usually
  133. # harmless because $srcdir is '.', but things will broke when you
  134. # start a VPATH build or use an absolute $srcdir.
  135. #
  136. # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  137. # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
  138. # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  139. # and then we would define $MISSING as
  140. # MISSING="\${SHELL} $am_aux_dir/missing"
  141. # This will work as long as MISSING is not called from configure, because
  142. # unfortunately $(top_srcdir) has no meaning in configure.
  143. # However there are other variables, like CC, which are often used in
  144. # configure, and could therefore not use this "fixed" $ac_aux_dir.
  145. #
  146. # Another solution, used here, is to always expand $ac_aux_dir to an
