Package: src:ecasound Version: 2.9.1-5 Severity: important Tags: sid stretch User: debian-gcc@lists.debian.org Usertags: libstdc++-cxx11 Background [1]: libstdc++6 introduces a new ABI to conform to the C++11 standard, but keeps the old ABI to not break existing binaries. Packages which are built with g++-5 from experimental (not the one from testing/unstable) are using the new ABI. Libraries built from this source package export some of the new __cxx11 or B5cxx11 symbols, and dropping other symbols. If these symbols are part of the API of the library, then this rebuild with g++-5 will trigger a transition for the library. What is needed: - Rebuild the library using g++/g++-5 from experimental. Note that most likely all C++ libraries within the build dependencies need a rebuild too. You can find the log for a rebuild in https://people.debian.org/~doko/logs/gcc5-20150701/ Search for "BEGIN GCC CXX11" in the log. - Decide if the symbols matching __cxx11 or B5cxx11 are part of the library API, and are used by the reverse dependencies of the library. - If there are no symbols matching __cxx11 or B5cxx11 in the symbols forming the library API, you should close this issue with a short explanation. - If there are no reverse dependencies, it should be the package maintainers decision if a transition is needed. However this might break software which is not in the Debian archive, and built against these packages. - If a library transition is needed, please prepare for the change. Rename the library package, append "v5" to the name of the package (e.g. libfoo2 -> libfoo2v5). Such a change can be avoided, if you have a soversion bump and you upload this version instead of the renamed package. Prepare a patch and attach it to this issue (mark this issue with patch), so that it is possible to NMU such a package. We'll probably have more than hundred transitions triggered. Then reassign the issue to release.debian.org and properly tag it as a transition issue, by sending an email to control@bugs.debian.org: user release.debian.org@packages.debian.org usertag <this issue> + transition block <this issue> by 790756 reassign <this issue> release.debian.org - If unsure if a transition is needed, please tag the issue with help to ask for feedback from other Debian developers. The libstdc++6 transition will be a large one, and it will come with a lot of pain. Please help it by preparing the follow-up transitions.
