如何在Eclipse CDT中启用C ++ 11 / C ++ 0x支持？ [英] How to enable C++11/C++0x support in Eclipse CDT?

问题描述

Eclipse 3.7.1
CDT 1.4.1
GCC 4.6.2

Eclipse 3.7.1 CDT 1.4.1 GCC 4.6.2

这是一段C ++ 11的示例代码：

This is an example of a piece of C++11 code:

auto text = std::unique_ptr<char[]>(new char[len]);

Eclipse编辑器抱怨：

The Eclipse editor complains about:

Function 'unique_ptr' could not be resolved

Makefile编译有效精细。如何使Eclipse停止抱怨此类错误？

The Makefile compilation works fine. How to make Eclipse stop complaining about these sort of errors?

推荐答案

我发现这篇在Eclipse论坛中的文章，只需遵循这些步骤即可，它对我有用。我在Windows上使用Cygwin设置使用Eclipse Indigo 20110615-0604。

I found this article in the Eclipse forum, just followed those steps and it works for me. I am using Eclipse Indigo 20110615-0604 on Windows with a Cygwin setup.

• 创建一个新的C ++项目


• 所有内容的默认选项


• 创建后，右键单击项目，然后转到属性


• C / C ++构建->设置->工具设置-> GCC C ++编译器->其他->其他标志。将 -std = c ++ 0x （或对于较新的编译器版本 -std = c ++ 11 放在最后） 。...除了GCC C ++编译器，我还有Cygwin编译器


• C / C ++ General->路径和符号->符号-> GNU C ++。单击添加...，然后将 __ GXX_EXPERIMENTAL_CXX0X __ 粘贴（确保在两个下划线之前加上并加上下划线）到名称中，并将值留为空白。


• 点击应用，执行

• Make a new C++ project
• Default options for everything
• Once created, right-click the project and go to "Properties"
• C/C++ Build -> Settings -> Tool Settings -> GCC C++ Compiler -> Miscellaneous -> Other Flags. Put -std=c++0x (or for newer compiler version -std=c++11 at the end . ... instead of GCC C++ Compiler I have also Cygwin compiler
• C/C++ General -> Paths and Symbols -> Symbols -> GNU C++. Click "Add..." and paste __GXX_EXPERIMENTAL_CXX0X__ (ensure to append and prepend two underscores) into "Name" and leave "Value" blank.
• Hit Apply, do whatever it asks you to do, then hit OK.

现在在Eclipse FAQ中也对此进行了描述： Eclipse FAQ / C ++ 11功能。

There is a description of this in the Eclipse FAQ now as well: Eclipse FAQ/C++11 Features.
