Note:
- *1: * Full C++11 support requires gcc 4.8 environment or newer on Linux*
- On Windows: when using Intel C++ compiler with Visual Studio 2010* or 2012*, the C++11 features supported by Visual C++ 2010/2012 are enabled by default. Use "/Qstd=c++11" to turn on the support for all other cases.
"char16_t/char32_t types" feature also requires Visual C++ 2015 or above. - On Linux or macOS: the C++11 features supported by gcc on the path are enabled by default. Use "-std=c++11" to turn on the support for all other cases.
- /Qstd=c++0x (-std=c++0x on Linux or macOS) is still supported. It is the same as /Qstd=c++11(-std=c++11 on Linux or macOS).
Please read the documentation for detail information under /Qstd (-std on Linux* or macOS*) option. - On Building Applications for Intel® Many Integrated Core Architecture (Intel® MIC Architecture)
- Linux: Note that language features available can depend on gcc* version installed. The version of gcc compiler, header files, and libraries that are provided as part of the Intel® Manycore Platform Software Stack (Intel® MPSS) distribution on Intel® MIC Architecture is an experimental 4.7.0 version. This version lacks full support for some gcc features that are available in the final release of the 4.7.0 gcc compiler and libraries. In particular, this version of gcc lacks the support for allocator_traits.
- Windows: The version of header files and libraries that are provided as part of the Intel® MPSS distribution on Intel® MIC Architecture is an experimental 4.7.0 version. This version lacks full support for some gcc* features that are available in the final release of the 4.7.0 gcc libraries. In particular, this version of gcc lacks the support for allocator traits.
