(Michael isn't around next week I was told and couldn't finish the job himself, so I end up having the joy to work on this… oh well.) std::string is omni-present in libapt-pkg and it is practically impossible to do anything without hitting at least one symbol using it, so rdeps are absolutely effected. SONAME in /sid is currently 4.12, we bump it up to 4.16 as /experimental has burned through 4.13, 4.14 and 4.15 and reusing those is probably not a good idea… (and 4.12v5 would have its own issues). libapt-inst is bumped as well from 1.5 to 1.7. In other words: binary-NEW. The apt version containing them will be called 1.0.10. The API is changed (beside the std::string and std::list change in gcc) in a small detail: As std::string doesn't do copy-on-write anymore and it turns out that we depended on this behavior: so we have to change debTranslationsIndex from using char* to std::string in constructor and member, but do not fear, this class isn't and actually can't be used by anyone expect libapt itself (but is used for everything involving Translation-* files, so you will end up noticing strange behavior if unfixed). All other abi changes are still confined to /experimental to avoid any additional risk for the gcc transition. apt has no c++ library build-dependencies (expect libstdc++6 of course) btw. I have made some test rebuilds, so that seems all well as far as I could test, but the biggest "test" in this regard aptitude hasn't a public patch (or at least I couldn't find it) for building with gcc5 yet. For the record: I tested and build everything on an UNCLEAN system with gcc5 from experimental (gcc version 5.2.1 20150723 (Debian 5.2.1-12)). You can find the results at: https://kalnischkies.de/tmp/unclean/apt/ Again, build on an UNCLEAN system, so I wouldn't upload it. Mainly there in case you want to compare with your results or whatever. Gory diff details can be found online at: https://anonscm.debian.org/cgit/apt/apt.git/log/?id=refs/heads/debian/sid-gcc5 Or of course in a git checkout, look for the 'debian/sid-gcc5' branch or the (signed by me) 1.0.10 tag. As usual no patch attached as the po-rebuilds kill it. Feel free to drop me a line by mail/irc if there is more I can/should do. Best regards David Kalnischkies
