| 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. |
