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：

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

-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.这篇关于icpc C ++ 11与gcc stdlib的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
