如何打开C ++ 0x的Intel C ++编译器12.1.2 [英] How to turn on C++0x of Intel C++ Compiler 12.1.2

问题描述

我在Arch Linux 3.2.1上安装了最新版本的Intel C ++ Compiler v12.1.2。当我使用icpc编译我的C ++文件

  icpc -O3 -DNDEBUG -std = gnu ++ 0x -o obj / main .o src / main.cpp -c 
  

或

  icpc -O3 -DNDEBUG -std = c ++ 0x -o obj / main.o src / main.cpp -c 
  
 
 
 
弹出警告
 警告＃2928：当使用带有c ++ 0x选项的GNU版本4.6时，__GXX_EXPERIMENTAL_CXX0X__宏被禁用
  
我的main.cpp包含许多C ++ 0x功能，如右值引用，自动等。但英特尔编译器没有工作在C ++ 0x模式。如何打开其C ++ 0x功能？
解决方案
 
 
 
安装libstdc ++ 4.5（或更早版本）
 
 
使用 icpc -gcc-name 问题是Intel编译器不支持GNU编译器从版本4.6开始的所有C ++ 0x功能。这会导致与GNU libstdc ++头不兼容，因为目前所有的C ++ 0x功能都受到一个唯一的宏 __ GXX_EXPERIMENTAL_CXX0X __ 的保护，不能单独启用或禁用。
 
I installed the latest version of Intel C++ Compiler v12.1.2 on Arch Linux 3.2.1. When I used icpc to compile my C++ file
icpc -O3 -DNDEBUG -std=gnu++0x -o obj/main.o src/main.cpp -c
or
icpc -O3 -DNDEBUG -std=c++0x -o obj/main.o src/main.cpp -c
A warning popped out
Warning #2928: the __GXX_EXPERIMENTAL_CXX0X__ macro is disabled when using GNU version 4.6 with the c++0x option
My main.cpp contains many C++0x features such as rvalue references, auto, etc. But the Intel compiler did not work in C++0x mode. How to turn on its C++0x features?
解决方案
I had to fight my way through this, but a quick solution seems to be:

Install libstdc++4.5 (or earlier)
compile with icpc -gcc-name=gcc-4.5 -std=c++0x
The problem is that Intel compilers do not support all the C++0x features that GNU compilers do starting from version 4.6. This causes incompatibilities with GNU libstdc++ headers since at present all the C++0x features are protected by a unique macro __GXX_EXPERIMENTAL_CXX0X__ and cannot be enabled or disabled singularly.
