Summary | 0015339: CXX_STANDARD does not support C++03 and C++14 | ||||||||
Description | CXX_STANDARD support only '98' and '11', but there is also C++03 standard that should be supported. When CXX_EXTENSIONS property is ON, "-std=gnu98" should be used, "-std=c++03" otherwise. C++14 standard is now finalized, so it could be added to CMake as well. GCC supports it since 4.8, Clang has complete support in version 3.4. MSVC 2013 also supports some C++14 features, but it does not need to be asked for enabling them. C++17 also may be enabled in newest clang by passing "-std=c++1z" argument. Not sure whether you are keen to standard drafts support to CMake, but you could add it as '1z' and then remove it when c++17 is finally published. I would not use '17' as its name, as name may be changed (C++11 was initialially called c++0x, because it was supposed to be published before 2010). | ||||||||

The '03' dialects are aliases for the '98' dialects. We don't need to alias it in CMake too I think. https://gcc.gnu.org/onlinedocs/gcc/C-Dialect-Options.html [^] CMake already knows the features of C++14 http://www.cmake.org/cmake/help/v3.1/prop_gbl/CMAKE_CXX_KNOWN_FEATURES.html [^] but the CXX_STANDARD target property documentation did not mention it. Fixed in Help: Document valid 14 value for CXX_STANDARD. (0015339) http://www.cmake.org/gitweb?p=cmake.git;a=commitdiff;h=72a0d6df [^] I think we should wait to get more experience/feedback on the CMake compile features feature, and wait for more regarding the content of C++17 before adding features described in it. |
