icc -mmic - c+11 support

 

   Hi 

      What is the level of support for c++ when using icc -mmic?

      This code 

   #include <memory>
#include <iostream>
int main()
{
  typedef std::pointer_traits<std::shared_ptr<int> >::rebind<double> another_pointer;
  std::shared_ptr<int> a;
  return 1;
}

Compiles the the host when using icpc -std=c++11  c11.cxx but fails with

icpc -mmic -std=c++11  c11.cxx
c11.cxx(6): error: qualified name is not allowed
    typedef std::pointer_traits<std::shared_ptr<int> >::rebind<double> another_pointer;
            ^

c11.cxx(6): error: expected a ";"
    typedef std::pointer_traits<std::shared_ptr<int> >::rebind<double> another_pointer;
                               ^

compilation aborted for c11.cxx (code 2)

C++11 support depends on the GCC version available on the system. When using -mmic, support depends on the GCC version installed as part of MPSS. See footnote #5 in this article for details: https://software.intel.com/en-us/articles/c0x-features-supported-by-intel-c-compiler

 Hi Amanda

  I assume then that c++11 is not fully supported on MIC code as it is based on gcc 4.7.  

  Given that one of the icc 16.0 beta test objectives is c++ 11 support are there any plans to update the MIC gcc version to provide full c++ 11 support during the beta test period?

 Thanks
