61 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
62 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
63 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
64 #
65 # Of course, Automake must honor this variable whenever it calls a
66 # tool from the auxiliary directory. The problem is that $srcdir (and
67 # therefore $ac_aux_dir as well) can be either absolute or relative,
68 # depending on how configure is run. This is pretty annoying, since
69 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
70 # source directory, any form will work fine, but in subdirectories a
71 # relative path needs to be adjusted first.
72 #
73 # $ac_aux_dir/missing
74 # fails when called from a subdirectory if $ac_aux_dir is relative
75 # $top_srcdir/$ac_aux_dir/missing
76 # fails if $ac_aux_dir is absolute,
77 # fails when called from a subdirectory in a VPATH build with
78 # a relative $ac_aux_dir
79 #
80 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
81 # are both prefixed by $srcdir. In an in-source build this is usually
82 # harmless because $srcdir is `.', but things will broke when you
83 # start a VPATH build or use an absolute $srcdir.
84 #
85 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
86 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
87 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
88 # and then we would define $MISSING as
89 # MISSING="\${SHELL} $am_aux_dir/missing"
90 # This will work as long as MISSING is not called from configure, because
91 # unfortunately $(top_srcdir) has no meaning in configure.
92 # However there are other variables, like CC, which are often used in
93 # configure, and could therefore not use this "fixed" $ac_aux_dir.
94 #
95 # Another solution, used here, is to always expand $ac_aux_dir to an
96 # absolute PATH. The drawback is that using absolute paths prevent a
97 # configured tree to be moved without reconfiguration.
