构建纸牌的多个错误

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反对票；我看不出这违反了任何 SO 准则。）

1) c:\mingw\lib\gcc\mingw32.9.3\include\c++\bits\c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. 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，但似乎没有用。这可能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 这是关于我的扑克牌头文件中的 std::array<Card,52> cards_; 行。这是我第一次尝试用多个 classes 或单个 class 构建一副纸牌，所以如果我犯了一个明显的错误，我深表歉意。

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做任何更改，我会在多个文件的其他地方收到更多错误；这正常吗？

Answer 1

您必须为 GNU 编译器设置 -std=c++11 标志。

根据 Eclipse 论坛：

右键单击该项目并转到 "Properties"
转到： C/C++ 构建 -> 设置 -> 工具设置 -> GCC C++ 编译器 -> 杂项 -> 其他标志。
在末尾加上“-std=c++11”。
