We use libstdc++ on Linux, with special hacks so that our binaries will actually run against older shared libstdc++ than the headers we compile with. (It's possible that libstdc++ prior to GCC 5 isn't completely C++11 compliant, but it's probably close enough for our current purposes.) See e.g. http://dxr.mozilla.org/mozilla-central/source/build/unix/stdc++compat/stdc++compat.cpp#27 http://dxr.mozilla.org/mozilla-central/source/config/gcc-stl-wrapper.template.h#55 for an idea of what we do. We haven't tried crossing the GCC 5 ABI breakage yet. -Nathan _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
