c++ - 在 Visual Studio 2010 中链接 boost 库时出现问题。

Question

我根据找到的指南编译了我的 boost 库 here并尝试使用 boost 文件系统库。

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

如果我在不包含 operations.hpp 的情况下进行编译，它可以正常工作。问题是当我使用 #define BOOST_LIB_DIAGNOSTIC它表明它在 boost 库中正确链接:

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

在项目选项中(在链接器选项组)在 dependencies 中添加缺少的库，并在附加目录中添加 boost 库的路径。或者，要启用自动链接(如果您将 boost 编译为 DLL)，请在项目的 C++ 选项的预处理器符号中定义 BOOST_ALL_DYN_LINK。
