Question

每当我尝试包含＆lt;时，我都会在win_object_handle_service.ipp中获取“:: UnregisterWaitEx” boost / asio.hpp＆gt;进入我的代码。

目前我在Windows 8.1上使用Code :: Blocks，MinGW编译器（它没有与IDE捆绑在一起）。

Boost是在mingw include文件夹之外构建的，但它包含在项目设置中。

我得到的确切错误：

我尝试了什么：

将_WIN32_WINNT设置为0x0601（再添加一个警告）
按照here中的说明（没有任何反应）将struct pollfd添加到winsock2.h
链接的boost正则表达式，系统和线程库（或至少尝试过）

提前致谢，

所以，我通过添加＆＃34; -D_WIN32_WINNT = 0x0501 -DWINVER = 0x0501＆＃34;来修复此错误。两个编译器链接器选项（在C :: B中）和#defines。猜猜我添加了_WIN32_WINNT错误。

使用Boost Asio时出错
