在Visial Studio 2010中链接boost库时遇到问题。

Question

我根据找到的指南here编译我的boost库，并试图使用boost文件系统库。

当我添加#include <boost\filesystem\operations.hpp>我收到以下错误：

如果我编译不包括operations.hpp它工作正常。问题是，当我使用#define BOOST_LIB_DIAGNOSTIC这表明，它是在Boost库正确链接：

Linking to lib file: libboost_filesystem-vc100-mt-gd-1_44.lib 
Linking to lib file: libboost_system-vc100-mt-gd-1_44.lib

在项目选项（在连接选项组）添加缺少的库的依赖关系，并添加路径提振附加目录中的库。或者，要启用自动链接（如果您将boost编译为DLL），请在C++选项的项目中的预处理器符号中定义BOOST_ALL_DYN_LINK。
