This is right, none of the elfutils tools use the libasm internals directly at the moment. But see, being paranoid below. > Package: libelf1 > Version: 0.156-2 > Depends: libc6 (>= 2.14) > > Package: libdw1 > Version: 0.156-2 > Depends: libbz2-1.0, libc6 (>= 2.14), libelf1 (>= 0.144), liblzma5 (>= > 5.1.1alpha+20120614), zlib1g (>= 1:1.2.2.3) This really should be libelf1 (= 0.156-2) since libdw uses some libelf internals. > Package: libasm1 > Version: 0.156-2 > Depends: libc6 (>= 2.14), libelf1 (>= 0.132), libdw1 (= 0.156-2) libasm doesn't use any libelf internals directly, so doesn't (currently) need to depend in the same version of libelf1. But it does use libebl and so does need to depend on the exact version of libdw (which contains the libebl backends). > And other packages will get Depends depending on the symbols they > use. Yes. Only the elfutils packages themselves are special.

I would just make them all depend on the exact version (= 156-2) just out of paranoia. Even if some currently don't use internals of others there isn't really an guarantee they won't in some future version. The elfutils libraries all provide a public API and should have a stable ABI. But their implementations might interdependent on some implementation details. Cheers, Mark -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
