libtool links against dependencies-of-dependencies, rather than just direct dependencies. This is correct behaviour on some platforms under some situations (one example is static linking). But when linking shared objects on modern Unixy platforms it's a pain in the ass since you end up with a load of bogus shared object dependencies that break things unnecessarily upon upgrades. as-needed works around this by making the linker only link things from the command line that resolve a name dependency (but name dependencies aren't the only dependency type). This means that most of the extras libtool adds in end up getting ignored, but it also means that things the programmer has explicitly said to link in get ignored too. The correct fix is to make libtool only link to dependencies of dependencies when doing, for example, static linking. Debian has a half-working patch for this that I posted earlier in the thread. -- Ciaran McCreesh
