|  | 67 | # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets | 
|  | 68 | # $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to | 
|  | 69 | # '$srcdir', '$srcdir/..', or '$srcdir/../..'. | 
|  | 70 | # | 
|  | 71 | # Of course, Automake must honor this variable whenever it calls a | 
|  | 72 | # tool from the auxiliary directory.  The problem is that $srcdir (and | 
|  | 73 | # therefore $ac_aux_dir as well) can be either absolute or relative, | 
|  | 74 | # depending on how configure is run.  This is pretty annoying, since | 
|  | 75 | # it makes $ac_aux_dir quite unusable in subdirectories: in the top | 
|  | 76 | # source directory, any form will work fine, but in subdirectories a | 
|  | 77 | # relative path needs to be adjusted first. | 
|  | 78 | # | 
|  | 79 | # $ac_aux_dir/missing | 
|  | 80 | #    fails when called from a subdirectory if $ac_aux_dir is relative | 
|  | 81 | # $top_srcdir/$ac_aux_dir/missing | 
|  | 82 | #    fails if $ac_aux_dir is absolute, | 
|  | 83 | #    fails when called from a subdirectory in a VPATH build with | 
|  | 84 | #          a relative $ac_aux_dir | 
|  | 85 | # | 
|  | 86 | # The reason of the latter failure is that $top_srcdir and $ac_aux_dir | 
|  | 87 | # are both prefixed by $srcdir.  In an in-source build this is usually | 
|  | 88 | # harmless because $srcdir is '.', but things will broke when you | 
|  | 89 | # start a VPATH build or use an absolute $srcdir. | 
|  | 90 | # | 
|  | 91 | # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, | 
|  | 92 | # iff we strip the leading $srcdir from $ac_aux_dir.  That would be: | 
|  | 93 | #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` | 
|  | 94 | # and then we would define $MISSING as | 
|  | 95 | #   MISSING="\${SHELL} $am_aux_dir/missing" | 
|  | 96 | # This will work as long as MISSING is not called from configure, because | 
|  | 97 | # unfortunately $(top_srcdir) has no meaning in configure. | 
|  | 98 | # However there are other variables, like CC, which are often used in | 
|  | 99 | # configure, and could therefore not use this "fixed" $ac_aux_dir. | 
|  | 100 | # | 
|  | 101 | # Another solution, used here, is to always expand $ac_aux_dir to an | 
|  | 102 | # absolute PATH.  The drawback is that using absolute paths prevent a | 
|  | 103 | # configured tree to be moved without reconfiguration. |
