this is still the way to go. C++11 support in libstdc++ is still marked as experimental in GCC 4.9, and if other toolchains are using libstdc++ this is valid for other toolchains too. C+11 support currently is incompatible across GCC versions (see ). This may affect you or not, but if you build a C++ application in c++11 mode you should make sure to build it with the same compiler version. > As far as I understand the whole debian should transition to C++11 ABI at > the same time. I don't think this is needed. You just have to make sure that you are using a compiler with a stable C++11 ABI *and* a stable libstdc++ ABI. GCC 5.0 promises to be such a compiler.
