4ee9c684 | 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. | |
