     23 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
     24 # $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
     25 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
     26 #
     27 # Of course, Automake must honor this variable whenever it calls a
     28 # tool from the auxiliary directory.  The problem is that $srcdir (and
     29 # therefore $ac_aux_dir as well) can be either absolute or relative,
     30 # depending on how configure is run.  This is pretty annoying, since
     31 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
     32 # source directory, any form will work fine, but in subdirectories a
     33 # relative path needs to be adjusted first.
     34 #
     35 # $ac_aux_dir/missing
     36 #    fails when called from a subdirectory if $ac_aux_dir is relative
     37 # $top_srcdir/$ac_aux_dir/missing
     38 #    fails if $ac_aux_dir is absolute,
     39 #    fails when called from a subdirectory in a VPATH build with
     40 #          a relative $ac_aux_dir
     41 #
     42 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
     43 # are both prefixed by $srcdir.  In an in-source build this is usually
     44 # harmless because $srcdir is '.', but things will broke when you
     45 # start a VPATH build or use an absolute $srcdir.
     46 #
     47 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
     48 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
     49 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
     50 # and then we would define $MISSING as
     51 #   MISSING="\${SHELL} $am_aux_dir/missing"
     52 # This will work as long as MISSING is not called from configure, because
     53 # unfortunately $(top_srcdir) has no meaning in configure.
     54 # However there are other variables, like CC, which are often used in
     55 # configure, and could therefore not use this "fixed" $ac_aux_dir.
     56 #
     57 # Another solution, used here, is to always expand $ac_aux_dir to an
     58 # absolute PATH.  The drawback is that using absolute paths prevent a
     59 # configured tree to be moved without reconfiguration.
