1. YES，the foo function is declared but not implemented.
2. That's my fault, I wrote it wrong.
3. No, actually in case 3, dtneeded name is exe/libhave.so, but soName is libhave.so in -lhave, so there are inconsistent. In case 4, dtneeded name is libhave.so, but soName is exe/libhave.so, alse inconsistent.
4. I'll try it.
