I want to add support for libc++, the c++ standard library attached to clang, to boost. Fixes required should not be attached to clang, as clang can use various standard libraries. Is there a standard way I should add the library, or just add the macro where needed.
You should add a header in boost/config/stdlib/ for libc++ and update boost/config/select_stdlib_config.hpp. Other than that, patches should be applied as needed.
The best macro to use for detecting libc++ is _LIBCPP_VERSION. Hopefully the changes required will be minimal.
One place where libc++ needs to be mentioned in is detail/container_fwd.hpp, as forward declarations simply don't work. Can I just attach _LIBCPP_VERSION to:
#if defined(BOOST_DETAIL_NO_CONTAINER_FWD) \ || ((defined(__GLIBCPP__) || defined(__GLIBCXX__)) \ && (defined(_GLIBCXX_DEBUG) || defined(_GLIBCXX_PARALLEL))) \ || BOOST_WORKAROUND(__BORLANDC__,> 0x551) \ || BOOST_WORKAROUND(__DMC__, BOOST_TESTED_AT(0x842)) \ || (defined(__SGI_STL_PORT) || defined(_STLPORT_VERSION))
Or is there a better / more offical way libc++ should be worked in?
