Why does git depend on two versions of libcrypto?

H.Merijn Brand· Feb 8, 2008, 09:46 UTC · lore

Don't know if this is a git question or a OpenSUSE question, but why does git depend on libcrypto.so.6 and not on libcrypto.so.0.9.8, like the rest does?

Isn't that asking for trouble? In my case, they're both linked to the same lib, so I guess I'm safe.

The answer is here. git was obviously built against a different version of OpenSSL than curl. This is an OpenSUSE problem.
