Question

我是c ++的新手，甚至更新。刚刚安装并将boost连接到Code :: Blocks后，我运行了一个示例代码，它似乎工作正常。

我开始浏览boost::asio tutorial。我真的试图复制并粘贴他们的代码，构建并运行它，但仍然会出错......

对于Eclipse，添加符号：_WIN32_WINNT val：0x0601（或对于您的Windows系统：http://msdn.microsoft.com/en-us/library/windows/desktop/aa383745%28v=vs.85%29.aspx）以解决您引用的前3行中的主要问题。我不使用代码块，但我想这个过程是类似的。

还要将BOOST_ROOT / stage / lib添加到库包含路径，并包含特定的boost_system- 任何库。
