Well, as far as I know (from a few dozen packages made for PLD) if you
specify version at 1:0:0 you'll get with a
symlink to
The version flag for libtool allows you to specify ABI versions, so
you can have installed for example and with different ABI/API versions
simultaneusly. The thing with adding, is just because people usually didn't get the
libtool bits right ;) It really makes things for packagers hard,
because if you change the version after the .so suffix you have to
rebuild every package depending on that library even if the ABI stays
the same. Of course this is all IMHO (see the and KDE libs for a
versioning scheme which is IMO more correct, eg., but if the version is 0.0.0 then usually the
--avoid-version parameter could be used (and it is usually patched to
it by packagers)
