Boost示例不能在VS2010上编译？

Question

我试着让网站上的一个boost示例运行起来：

http://www.boost.org/doc/libs/1_47_0/doc/html/boost_asio/example/http/client/async_client.cpp

但每当我构建并尝试执行时，我都会从VS2010获得以下内容：

1>------ Build started: Project: highfreqdemo, Configuration: Debug Win32 ------

我有点不确定到底该怎么做才能弥补这个问题？

Answer 1

将指令添加到“stdAfx.h”或重新生成预编译头

您的项目配置了预编译头支持，但您尚未在源文件中包含预编译头。

预编译头文件(在本例中为StdAfx.h)需要包含在每个配置为使用预编译头的源文件的最顶部。

包括此文件或禁用预编译头文件(在项目属性中，在C/C++ ->预编译头文件下，将预编译头文件属性设置为“不使用预编译头文件；也可以为单个源文件设置该属性)。”

Answer 2

警告和错误非常清楚；在包含标准和Boost头文件之前，需要将#include "StdAfx.h"添加到highfreqdemo.cpp文件中。
