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 |
