GCC 5 uses the new C++ ABI by default. When building new code, you might run
into link time errors like:
...: undefined reference to '_ZNSt6chrono12steady_clock3nowEv@GLIBCXX_3.4.17'
Or you might see linkage failures with "std::__cxx11::string" in the output.
These are signs that you need to rebuild packages using the new C++ ABI.
You can quickly do so by using revdep-rebuild like so:
# revdep-rebuild --library 'libstdc\+\+\.so\.6'
We shouldn't assume a particular PM/toolset in news items, IMO. Just
saying that people might have to rebuild packages linked against
libstdc++.so.6 should be enough.
They can read the docs if they don't know how.
Nothing precludes adding "see .... if you use paludis or clang."
However, I'd like to see the above in there.
