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