72 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets |
|
73 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to |
|
74 # `$srcdir', `$srcdir/..', or `$srcdir/../..'. |
|
75 # |
|
76 # Of course, Automake must honor this variable whenever it calls a |
|
77 # tool from the auxiliary directory. The problem is that $srcdir (and |
|
78 # therefore $ac_aux_dir as well) can be either absolute or relative, |
|
79 # depending on how configure is run. This is pretty annoying, since |
|
80 # it makes $ac_aux_dir quite unusable in subdirectories: in the top |
|
81 # source directory, any form will work fine, but in subdirectories a |
|
82 # relative path needs to be adjusted first. |
|
83 # |
|
84 # $ac_aux_dir/missing |
|
85 # fails when called from a subdirectory if $ac_aux_dir is relative |
|
86 # $top_srcdir/$ac_aux_dir/missing |
|
87 # fails if $ac_aux_dir is absolute, |
|
88 # fails when called from a subdirectory in a VPATH build with |
|
89 # a relative $ac_aux_dir |
|
90 # |
|
91 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir |
|
92 # are both prefixed by $srcdir. In an in-source build this is usually |
|
93 # harmless because $srcdir is `.', but things will broke when you |
|
94 # start a VPATH build or use an absolute $srcdir. |
|
95 # |
|
96 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, |
|
97 # iff we strip the leading $srcdir from $ac_aux_dir. That would be: |
|
98 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` |
|
99 # and then we would define $MISSING as |
|
100 # MISSING="\${SHELL} $am_aux_dir/missing" |
|
101 # This will work as long as MISSING is not called from configure, because |
|
102 # unfortunately $(top_srcdir) has no meaning in configure. |
|
103 # However there are other variables, like CC, which are often used in |
|
104 # configure, and could therefore not use this "fixed" $ac_aux_dir. |
|
105 # |
|
106 # Another solution, used here, is to always expand $ac_aux_dir to an |
|
107 # absolute PATH. The drawback is that using absolute paths prevent a |
|
108 # configured tree to be moved without reconfiguration. |
