67 | <div class="contents"> | |
68 | <div class="textblock"><p>The support of C++11 <code>char16_t</code> and <code>char32_t</code> is experimental, mostly does not work and not intended to be used in production with current latest compilers: GCC-4.5, MSVC10 till major compiler's flaws would be fixed.</p> | |
69 | <h1><a class="anchor" id="status_of_cpp0x_characters_support_gnu"></a> | |
70 | GNU GCC 4.5/C++11 Status</h1> | |
71 | <p>GNU C++ compiler provides decent support of C++11 characters however:</p> | |
72 | <ol type="1"> | |
73 | <li>Standard library does not install any std::locale::facets for this support so any attempt to format numbers using <code>char16_t</code> or <code>char32_t</code> streams would just fail.</li> | |
74 | <li>Standard library misses specialization for required <code>char16_t/char32_t</code> locale facets, so "std" backends is not build-able as essential symbols missing, also <code>codecvt</code> facet can't be created as well.</li> | |
75 | </ol> | |
76 | <h1><a class="anchor" id="status_of_cpp0x_characters_support_msvc"></a> | |
77 | Visual Studio 2010 (MSVC10)/C++11 Status</h1> | |
78 | <p>MSVC provides all required facets however:</p> | |
79 | <ol type="1"> | |
80 | <li>Standard library does not provide installations of std::locale::id for these facets in DLL so it is not usable with <code>/MD</code>, <code>/MDd</code> compiler flags and requires static link of the runtime library.</li> | |
81 | <li><code>char16_t</code> and <code>char32_t</code> are not distinct types but rather aliases of unsigned short and unsigned types which contradicts to C++11 requirements making it impossible to write <code>char16_t/char32_t</code> to stream and causing multiple faults.</li> | |
82 | </ol> | |
83 | <p>If you want to build or test Boost.Locale with C++11 char16_t and char32_t support you should pass <code>cxxflags="-DBOOST_LOCALE_ENABLE_CHAR32_T -DBOOST_LOCALE_ENABLE_CHAR16_T"</code> to <code>b2</code> during build and define <code>BOOST_LOCALE_ENABLE_CHAR32_T</code> and <code>BOOST_LOCALE_ENABLE_CHAR32_T</code> when using Boost.Locale </p> | |
