"namespaces in rpms" would not be enough. The OS environment would
need to support the same namespaces, too, or else there would still be
a run-time race between multiple minor versions of the same library.
If your library has a different name, how can it conflict? Or even if
your application puts your library location first in a search path?
Notice that several libraries and applications can even be built with
a different feature-set.
Which is why multiple versions should be expected to co-exist.
Even multiple major releases of libraries
cannot coexist peacefully, if not all packagers take extra (sometimes
huge) efforts to avoid conflicts between data/doc/development files,
and e.g. package them as "libfoo2" and "libfoo3".
Doesn't that tell you something?
but everyone wants to pretend that theirs is the only version
that matters.
It's not that simple. There are many factors.
I used to hear about .dll conflict problems under windows all the time
but I haven't in ages. Did they learn something?
