icpc C ++ 11与gcc stdlib [英] icpc C++11 with gcc stdlib

问题描述

我使用icpc（非可选），我编译与-std = c ++ 0x所以我可以使用lambas。

但是，当我这样做时，它使用gcc stdlib创建havok，并支持另一个不支持的功能。

我已尝试定义

  __ GXX_EXPERIMENTAL_CXX0X__ 
   
 
但这没有帮助。
 
 
 
所以，我想要的是能够使用c ++ 0x 
 $ c 
 
 
 
 
 
 
 gcc 4.6 
 b 
 $ b 
编辑错误示例：
  / usr / include / c ++ / 4.6.2 / type_traits（74）：error：identifierconstexpr未定义
 static constexpr _Tp value = __v; 
 ^ 
 
 /usr/include/c++/4.6.2/type_traits(74）：error：expected a; 
 static constexpr _Tp value = __v; 
 ^ 
 
 /usr/include/c++/4.6.2/type_traits(75）：error：memberstd :: integral_constant< _Tp，__v> :: _ Tp不是类型name 
 typedef _Tp value_type; 
 ^ 
 
 /usr/include/c++/4.6.2/type_traits(76）：error：memberstd :: integr_constant< _Tp，__v> :: _ Tp不是类型name 
 typedef integral_constant< _Tp，__v>类型; 
 ^ 
 
 /usr/include/c++/4.6.2/type_traits(77）：错误：标识符constexpr未定义
 constexpr operator value_type（）{return value; } 
 ^ 
 
 /usr/include/c++/4.6.2/type_traits(87）：error：identifierconstexpr未定义
 constexpr _Tp integral_constant< _Tp，__v> ：：值; 
  
 
 
解决方案
错误显然指向C ++ 11代码，所以它听起来像你想要防止编译器看到任何，例如与 -U__GXX_EXPERIMENTAL_CXX0X __ （等效的GCC选项）。 p> 
 
 
但是，如果ICC在 -std = c ++ 0x 下为您定义，您应该使用的库的版本（或在您的本地ICC安装中查找库）。很难确定C ++ 03库足以编译C ++ 11代码。
 
I am using icpc (non optional) and I am compiling with -std=c++0x so I can use lambas. 

However when I do so it creates havok with gcc stdlib with features that one supports that the other doesn't.

I have tried defining
__GXX_EXPERIMENTAL_CXX0X__
but that didn't help.

So ideally what I am asking for is the ability to use the c++0x language features with the C++03 stdlib.

gcc 4.6

icc 12.1]

解决方案
The errors obviously point to C++11 code, so it sounds like you want to prevent the compiler from seeing any of that, such as with -U__GXX_EXPERIMENTAL_CXX0X__ (the equivalent GCC option).

However, if ICC is defining this for you under -std=c++0x, then you should find out what version of the library you are supposed to use (or look for a library in your local ICC installation). It's far from certain that the C++03 library is sufficient to compile C++11 code.
