[cfe-dev] Using libc++ in a published app

[David Irvine]

Do you have instructions for how you achieved that. I would be very
interested and happy to document them. We have some instructions here
https://github.com/maidsafe/MaidSafe/wiki/Hacking-with-Clang-llvm-abi-and-llvm-libc
that
I would love to update for releasing static linked binaries in linux (and
OSX fro that matter).
