unique_ptr在eclipse中自动完成 [英] unique_ptr autocomplete in eclipse

问题描述

我正在玩unique_ptr。在我的最后一篇文章中，人们帮助我编译了一个使用此指针的程序，方法是指定-std = c ++ 0x在编译期间。
现在我想知道是否有任何方法来指示eclipse在自动完成时考虑c ++ 11？

unique_ptr不会出现在std ::命名空间的列表中，也不能找到与unique_ptr相关联的方法（重置，移动...）。

谢谢

= 201103L）。

正如其他人提到的，用-std = c ++ 0x或更高版本编译c ++标准（-std = c ++ 11或-std = c ++ 14）解决编译错误，但不解决eclipse索引和自动完成问题

为了解决eclipse索引问题，我将__cplusplus预处理器宏添加到项目构建属性中，值为201103L，然后刷新索引;

要添加预处理器宏：

在项目浏览器上右键单击项目>>属性>> C / C ++通用>>预处理器包括>>条目>> GNU C ++ >> CDT用户设置条目>>添加... >>预处理器宏

然后条目a名称为__cplusplus和值201103L的宏;

之后，要刷新索引，请执行：

项目浏览器上的右键项目>> >>索引>>重建;

Ps：我使用gcc 4.9.2和eclipse Luna在ubuntu 15.04 64bits

I am playing with unique_ptr. In my last post people helped me compiling a program that used this pointer by specifying the -std=c++0x during compilation. Now i was wondering if there is any way to instruct eclipse to consider c++11 while auto-completing?
unique_ptr is not coming in the list of std:: namespace, nor I can find the methods (reset, move...) associated with a unique_ptr.

Thank you vahid

解决方案

The "memory" header (probably found at /usr/include/c++/4.9/memory) only includes "unique_ptr.h" and "shared_ptr.h" (probably found at /usr/include/c++/4.9/bits/unique_ptr.h and /usr/include/c++/4.9/bits/shared_ptr.h) if the macro "__cplusplus" is equal or greather than "201103L". Check memory.h for yourself to see the "#if" preprocessor condition there, at line 69 (or search for the string "#if __cplusplus >= 201103L").

As others mentioned, compiling with "-std=c++0x" or later c++ standards (-std=c++11 or -std=c++14) solves the compilation errors, but not the eclipse indexing and autocomplete problem.

To solve the eclipse indexing issue I added the "__cplusplus" Preprocessor Macro to the project build properties, with the value "201103L", and afterwards I refreshed the index;

To add the preprocessor macro:

"right click the project on project explorer" >> properties >> C/C++ General >> Preprocessor Includes >> Entries >> GNU C++ >> CDT User Settings Entries >> Add... >> Preprocessor Macro;

Then entry a macro with name "__cplusplus" and value "201103L";

Afterwards, to refresh the index, do:

"right click project on project explorer" >> Index >> Rebuild;

Ps.: I was using gcc 4.9.2 and eclipse Luna (4.4.2), on ubuntu 15.04 64bits
