adam@17: # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
adam@17: # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
adam@17: # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
adam@17: #
adam@17: # Of course, Automake must honor this variable whenever it calls a
adam@17: # tool from the auxiliary directory.  The problem is that $srcdir (and
adam@17: # therefore $ac_aux_dir as well) can be either absolute or relative,
adam@17: # depending on how configure is run.  This is pretty annoying, since
adam@17: # it makes $ac_aux_dir quite unusable in subdirectories: in the top
adam@17: # source directory, any form will work fine, but in subdirectories a
adam@17: # relative path needs to be adjusted first.
adam@17: #
adam@17: # $ac_aux_dir/missing
adam@17: #    fails when called from a subdirectory if $ac_aux_dir is relative
adam@17: # $top_srcdir/$ac_aux_dir/missing
adam@17: #    fails if $ac_aux_dir is absolute,
adam@17: #    fails when called from a subdirectory in a VPATH build with
adam@17: #          a relative $ac_aux_dir
adam@17: #
adam@17: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
adam@17: # are both prefixed by $srcdir.  In an in-source build this is usually
adam@17: # harmless because $srcdir is `.', but things will broke when you
adam@17: # start a VPATH build or use an absolute $srcdir.
adam@17: #
adam@17: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
adam@17: # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
adam@17: #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
adam@17: # and then we would define $MISSING as
adam@17: #   MISSING="\${SHELL} $am_aux_dir/missing"
adam@17: # This will work as long as MISSING is not called from configure, because
adam@17: # unfortunately $(top_srcdir) has no meaning in configure.
adam@17: # However there are other variables, like CC, which are often used in
adam@17: # configure, and could therefore not use this "fixed" $ac_aux_dir.
adam@17: #
adam@17: # Another solution, used here, is to always expand $ac_aux_dir to an
