| 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
|

| 108 | # harmless because $srcdir is '.', but things will broke when you
|

| 109 | # start a VPATH build or use an absolute $srcdir.

|
|---|
| 113 | # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
