---|
| 104 | # a relative $ac_aux_dir |
---|
| 105 | # |
---|
| 106 | # The reason of the latter failure is that $top_srcdir and $ac_aux_dir |
---|
| 107 | # are both prefixed by $srcdir. In an in-source build this is usually |
---|
[44f44617] | 108 | # harmless because $srcdir is '.', but things will broke when you |
---|
[a77e7b5] | 109 | # start a VPATH build or use an absolute $srcdir. |
---|
| 110 | # |
---|
| 111 | # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, |
---|
| 112 | # iff we strip the leading $srcdir from $ac_aux_dir. That would be: |
---|
| 113 | # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` |
---|
