  126. # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
  127. # $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
  128. # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
  129. #
  130. # Of course, Automake must honor this variable whenever it calls a
  131. # tool from the auxiliary directory. The problem is that $srcdir (and
  132. # therefore $ac_aux_dir as well) can be either absolute or relative,
  133. # depending on how configure is run. This is pretty annoying, since
  134. # it makes $ac_aux_dir quite unusable in subdirectories: in the top
  135. # source directory, any form will work fine, but in subdirectories a
  136. # relative path needs to be adjusted first.
  137. #

  142. # fails when called from a subdirectory in a VPATH build with
  143. # a relative $ac_aux_dir
  144. #
  145. # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
  146. # are both prefixed by $srcdir. In an in-source build this is usually
  147. # harmless because $srcdir is '.', but things will broke when you
  148. # start a VPATH build or use an absolute $srcdir.
  149. #
  150. # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
  151. # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
  152. # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
  153. # and then we would define $MISSING as
  154. # MISSING="\${SHELL} $am_aux_dir/missing"
  155. # This will work as long as MISSING is not called from configure, because
  156. # unfortunately $(top_srcdir) has no meaning in configure.
  157. # However there are other variables, like CC, which are often used in
  158. # configure, and could therefore not use this "fixed" $ac_aux_dir.
  159. #
  160. # Another solution, used here, is to always expand $ac_aux_dir to an
  161. # absolute PATH. The drawback is that using absolute paths prevent a
