The MPlayer and MySQL examples are different. For MPlayer it's the link |
| 14 |
to .so.<complete versionnumber> that means you need to recompile. |

But for MySQL v4, even if you linked just to the plain .so, you had to |
| 17 |
recompile, because the API and structures changed. If you just left it |
| 18 |
there and tried to run things, they would segfault. |
