I'm trying to install libbitcoin on Mac os 10.9, with Eclipse for C++.

I follow the instructions given on github (https://github.com/libbitcoin/libbitcoin), then I include:

#include <bitcoin/bitcoin.hpp>
using namespace bc;

The installation seems fine but when I build the project (cap4.cpp) I get the following errors in Eclipse:

It looks like there are issues with gcc on Mac. On an issue in the libbitcoin github repository 'evoskuil' states:

gcc on osx is problematic because the ABI implementation is incomplete.

It is further suggested to use "the native Mac clang++/clang compiler" instead of gcc.

The libbitcoin Macintosh readme prescribes:

Libbitcoin requires a C++11 compiler, currently minimum GCC 4.8.0 or Clang based on LLVM 3.5.
