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