构建一副纸牌的多个错误

在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反对票;我看不出这如何违反任何 SO 准则。

1）c:mingwlibgccmingw324.9.3includec++bitsc++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support is currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler options我试图在Eclipse Mars中添加标志，但它似乎没有奏效。难道这就是我唯一缺少的东西吗？

2） DeckOfCards.h:21:8: error: 'array' in namespace 'std' does not name a template type 这是关于我的一副牌头文件中的std::array<Card,52> cards_;行。这是我第一次尝试构建一副具有多个类别的纸牌......或者一个单一的类，所以如果我犯了一个明显的错误，我道歉。

编辑：来自编译器的确切消息：

如果我在收到

这些错误后第二次重新编译而不更改任何内容，我会在多个文件的其他任何地方收到大量错误;这正常吗？

你必须

为 GNU 编译器设置 -std=c++11 标志。

根据Eclipse论坛：

右键单击项目并转到"属性"
转到：C/C++ 构建 ->设置 -> 工具设置 -> GCC C++编译器 ->杂项 ->其他标志。
把"-std=c++11"放在最后。
