when GCC 5 is the default
has caused the Debian Bug report #791165,

This means that you claim that the problem has been dealt with.
If this is not the case it is now your responsibility to reopen the
Bug report if necessary, and/or fix the problem forthwith.

Package: src:libsdl-sge
Version: 030809dfsg-4
Severity: important
Tags: sid stretch
User: [email protected]
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
[email protected]:
user [email protected]
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.

Rebuilt and uploaded a few days ago, and the transition of GCC 5 will
move to testing tonight, so I think that this can be closed now.
