在C++中使用算法头文件出错

我制作了一个unix域服务器客户端。它工作完美，没有任何错误

然后我想使用来自算法头文件的random_shuffle函数。所以我只包含算法头文件。我没有做任何其他的改变。但现在在编译时，我得到了以下错误：

game.cpp:102:85: error: no match for ‘operator!=’ in ‘std::bind(_Functor&&, _ArgTypes&& ...)

我没有做任何其他事情，我只是包括这个文件，那么为什么我会得到这个错误

如果有帮助，我将使用以下代码行编译它：

g++ -std=c++0x -I /usr/include/postgresql -lpq -fpermissive -c game.cpp

---

这是一个典型的名称冲突案例，因为不分青红皂白地使用using指令和在全局命名空间中导入的C API

您打算调用的绑定是用于中套接字的全局函数，但编译器更喜欢中提供的std:：bind，您可能是用臭名昭著的using namespace std；导入该绑定的

要消除歧义，请告诉编译器使用全局绑定，而不是std中的绑定：

运算符前面没有任何名称空间意味着从全局名称空间中获取它，在全局名称空间中，除非原始头被包装在名称空间块中，否则将放置每个C API

---

无论如何，放弃使用名称空间std可能是更好的选择；指令，更倾向于在需要时使用std:：或仅使用实际经常使用的内容进行导入。

除了包含，您还添加了一个使用名称空间std；或者其他什么。因此，编译器假定您需要std:：bind，而实际上您需要使用：：bind。另一种可能性是将系统函数封装在自己的小源文件中，这在任何情况下都不是一个坏主意，如果您希望将您的软件移植到具有不同调用的不同操作系统上运行，当然，然后使用一个合适的名称空间，该名称空间不会与其他组件发生冲突！或者只使用std中您想要的内容，而不是将整个名称空间拖入。ie：使用std:：string；
