   41 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
   42 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
   43 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
   44 #
   45 # Of course, Automake must honor this variable whenever it calls a
   46 # tool from the auxiliary directory.  The problem is that $srcdir (and
   47 # therefore $ac_aux_dir as well) can be either absolute or relative,
   48 # depending on how configure is run.  This is pretty annoying, since
   49 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
   50 # source directory, any form will work fine, but in subdirectories a
   51 # relative path needs to be adjusted first.
   52 #
   53 # $ac_aux_dir/missing
   54 #    fails when called from a subdirectory if $ac_aux_dir is relative
   55 # $top_srcdir/$ac_aux_dir/missing
   56 #    fails if $ac_aux_dir is absolute,
   57 #    fails when called from a subdirectory in a VPATH build with
   58 #          a relative $ac_aux_dir
   59 #
   60 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
   61 # are both prefixed by $srcdir.  In an in-source build this is usually
   62 # harmless because $srcdir is `.', but things will broke when you
   63 # start a VPATH build or use an absolute $srcdir.
   64 #
   65 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
   66 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
   67 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
   68 # and then we would define $MISSING as
   69 #   MISSING="\${SHELL} $am_aux_dir/missing"
   70 # This will work as long as MISSING is not called from configure, because
   71 # unfortunately $(top_srcdir) has no meaning in configure.
   72 # However there are other variables, like CC, which are often used in
   73 # configure, and could therefore not use this "fixed" $ac_aux_dir.
   74 #
   75 # Another solution, used here, is to always expand $ac_aux_dir to an
   76 # absolute PATH.  The drawback is that using absolute paths prevent a
   77 # configured tree to be moved without reconfiguration.
