Question

尝试编译我的文件时收到两个错误。（在没有解释的情况下收到了投票;我没有看到这违反了任何SO准则。）

1） std::array<Card,52> cards_; 我试图在Eclipse Mars中添加标记，但它似乎没有效果。这可能是我唯一缺少的吗？

2） 07:56:55 **** Incremental Build of configuration Debug for project TexasHoldem **** Info: Internal Builder is used for build g++ -O0 -g3 -Wall -c -fmessage-length=0 -o TexasHoldemMain.o "..\\TexasHoldemMain.cpp" In file included from c:\mingw\lib\gcc\mingw32\4.9.3\include\c++\array:35:0, from ..\DeckOfCards.h:11, from ..\TexasHoldemMain.cpp:5: c:\mingw\lib\gcc\mingw32\4.9.3\include\c++\bits\c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard.

编辑：编译器的确切消息：

 * DeckOfCards.h

#ifndef DECKOFCARDS_H_
#define DECKOFCARDS_H_

#include <array>

class DeckOfCards
{

    public:
        DeckOfCards();
        void printDeck();

    private:
        std::array<Card,52> cards_;


};

#endif /* DECKOFCARDS_H_ */

如果我在收到这些错误后第二次重新编译而没有改变任何内容，我会在多个文件的其他地方收到更多错误;那是正常的吗？

Answer 1

你必须为GNU编译器设置-std = c ++ 11标志。

根据Eclipse论坛：

右键单击项目，然后转到＆＃34;属性＆＃34;
转到： C / C ++ Build - ＆gt;设置 - ＆gt;工具设置 - ＆gt; GCC C ++编译器 - ＆gt; 其他 - ＆gt;其他旗帜。
Put＆＃34; -std = c ++ 11＆＃34;最后。
