66 | | # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets |
67 | | # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to |
68 | | # `$srcdir', `$srcdir/..', or `$srcdir/../..'. |
69 | | # |
70 | | # Of course, Automake must honor this variable whenever it calls a |
71 | | # tool from the auxiliary directory. The problem is that $srcdir (and |
72 | | # therefore $ac_aux_dir as well) can be either absolute or relative, |
73 | | # depending on how configure is run. This is pretty annoying, since |
74 | | # it makes $ac_aux_dir quite unusable in subdirectories: in the top |
75 | | # source directory, any form will work fine, but in subdirectories a |
76 | | # relative path needs to be adjusted first. |
77 | | # |
78 | | # $ac_aux_dir/missing |
79 | | # fails when called from a subdirectory if $ac_aux_dir is relative |
80 | | # $top_srcdir/$ac_aux_dir/missing |
81 | | # fails if $ac_aux_dir is absolute, |
82 | | # fails when called from a subdirectory in a VPATH build with |
83 | | # a relative $ac_aux_dir |
84 | | # |
85 | | # The reason of the latter failure is that $top_srcdir and $ac_aux_dir |
86 | | # are both prefixed by $srcdir. In an in-source build this is usually |
87 | | # harmless because $srcdir is `.', but things will broke when you |
88 | | # start a VPATH build or use an absolute $srcdir. |
89 | | # |
90 | | # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, |
91 | | # iff we strip the leading $srcdir from $ac_aux_dir. That would be: |
92 | | # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` |
93 | | # and then we would define $MISSING as |
94 | | # MISSING="\${SHELL} $am_aux_dir/missing" |
95 | | # This will work as long as MISSING is not called from configure, because |
96 | | # unfortunately $(top_srcdir) has no meaning in configure. |
97 | | # However there are other variables, like CC, which are often used in |
98 | | # configure, and could therefore not use this "fixed" $ac_aux_dir. |
99 | | # |
100 | | # Another solution, used here, is to always expand $ac_aux_dir to an |
101 | | # absolute PATH. The drawback is that using absolute paths prevent a |
102 | | # configured tree to be moved without reconfiguration. |
