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.
