Hi, here are my notes on what C++11 features might be usable unconditionally for KF5.
regards, Volker C++11 Support in KF5 ==================== Minimum compiler requirement: MSVC 2010, GCC 4.5 Possible C++11 features based on http://wiki.apache.org/stdcxx/C++0xCompilerSupport: - auto - decltype (v1.0) - extern template - lambda (v1.0) - local and unnamed types as template arguments - long long - new function declaration syntax for deduced return types - right angle brackets - rvalue refs (v2.0) / std::move - static_assert - built-in type traits - override/final (v0.8) Possible C++11 features for MSVC 2010 according to Qt: # if _MSC_VER >= 1400 /* C++11 features supported in VC8 = VC2005: */ # define Q_COMPILER_VARIADIC_MACROS # define Q_DECL_OVERRIDE override # define Q_DECL_FINAL sealed # endif # if _MSC_VER >= 1600 /* C++11 features supported in VC10 = VC2010: */ # define Q_COMPILER_AUTO_FUNCTION # define Q_COMPILER_AUTO_TYPE # define Q_COMPILER_LAMBDA # define Q_COMPILER_DECLTYPE # define Q_COMPILER_RVALUE_REFS # define Q_COMPILER_STATIC_ASSERT Possible C++11 features for GCC according to Qt: # if (__GNUC__ * 100 + __GNUC_MINOR__) >= 403 /* C++11 features supported in GCC 4.3: */ # define Q_COMPILER_DECLTYPE # define Q_COMPILER_RVALUE_REFS # define Q_COMPILER_STATIC_ASSERT # define Q_COMPILER_VARIADIC_MACROS # endif # if (__GNUC__ * 100 + __GNUC_MINOR__) >= 404 /* C++11 features supported in GCC 4.4: */ # define Q_COMPILER_AUTO_FUNCTION # define Q_COMPILER_AUTO_TYPE # define Q_COMPILER_CLASS_ENUM # define Q_COMPILER_DEFAULT_MEMBERS # define Q_COMPILER_DELETE_MEMBERS # define Q_COMPILER_EXTERN_TEMPLATES # define Q_COMPILER_INITIALIZER_LISTS # define Q_COMPILER_UNICODE_STRINGS # define Q_COMPILER_VARIADIC_TEMPLATES # endif # if (__GNUC__ * 100 + __GNUC_MINOR__) >= 405 /* C++11 features supported in GCC 4.5: */ # define Q_COMPILER_LAMBDA # define Q_COMPILER_RAW_STRINGS # endif Further reference for MSVC 2010: http://blogs.msdn.com/b/vcblog/archive/2010/04/06/c-0x-core-language-features-in-vc10-the-table.aspx Relevant features to evaluate for unconditional use: - auto - rvalue refs (without rvalue refs for *this) - lambda - override
