|
|
# - shared libperl support is tricky. if ever libperl.a ends up |
| 17 |
|
|
# in /usr/local/lib/* it can override any subsequent builds of |
| 18 |
|
|
# that same perl release. to make sure you know where the shared |
| 19 |
|
|
# libperl.a is coming from do a 'dump -Hv perl' and check all the |
| 20 |
|
|
# library search paths in the loader header. |
| 21 |
|
|
# |
| 22 |
|
|
# it would be nice to warn the user if a libperl.a exists that is |
| 23 |
|
|
# going to override the current build, but that would be complex. |
| 24 |
|
|
# |
| 25 |
