If you change
#if defined( __clang__ ) && defined( __has_extension ) # if __has_extension( __c_atomic__ ) # define BOOST_SP_HAS_CLANG_C11_ATOMICS # endif #endif
in sp_counted_base.hpp to
#if defined( __clang__ ) && defined( __has_extension ) && !defined( __c2__ ) # if __has_extension( __c_atomic__ ) # define BOOST_SP_HAS_CLANG_C11_ATOMICS # endif #endif
does it work then?
I also had to do the same for two other cases, but in the end sp_counted_base_w32.hpp worked and the entire filesystem dll built OK. Furthermore, all the test programs are passing! The test programs were compiled with the regular msvc compiler and then linked against the clang compiled dll. Turns out all that has to be done to call clang from the command line is to add "c:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\Clang 3.7\bin\x86" to the path, so it should be easy to see if Boost.Build will work. --Beman
