使用 Boost Asio 时出错

Question

每当我尝试将 < boost/asio.hpp > 包含到我的代码中时，我在 win_object_handle_service.ipp 中得到“::UnregisterWaitEx is not declared”。

目前我在 Windows 8.1.Code::Blocks 上使用 MinGW 编译器（未与 IDE 捆绑在一起）。

Boost 是在 mingw 包含文件夹之外构建的，但包含在项目设置中。

我得到的确切错误：

我尝试过的：

将 _WIN32_WINNT 设置为 0x0601（仅添加了一个警告）
按照 here 中的说明将 struct pollfd 添加到 winsock2.h（没有任何反应）
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，

因此，我通过将“-D_WIN32_WINNT=0x0501 -DWINVER=0x0501”添加到两个编译器链接器选项（在 C::B 中）和#defines 来修复此错误。猜猜我添加 _WIN32_WINNT 不知何故错误。
