No. > Or will it be easier for older OS X versions to migrate to libc++? No. > Or is it something that will in fact mostly/only benefit Linux users? Yes. This is meant to keep Clang compatible with ABI changes to GCC 5.1's libstdc++. http://llvm.org/releases/3.9.0/docs/ReleaseNotes.html#gcc-abi-tag https://llvm.org/bugs/show_bug.cgi?id=23529 vq P.S. Incidentally, this implies that g++ 4.x is also ABI-incompatible with libstdc++ 5.1. Have we encountered any issues along these lines? _______________________________________________ macports-dev mailing list [email protected] https://lists.macosforge.org/mailman/listinfo/macports-dev
