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