我正在使用由 BoostPro Computing 安装程序安装的 boost 库。我在 Windows 7 64 位机器上使用 VS 2010。我想动态链接到 boost，所以我在安装程序中选择了前两个选项（多线程调试 DLL 和多线程 DLL，我相信它们被调用了）。一些已安装库的示例是：
boost_bzip2-vc100-mt-1_51.lib
boost_bzip2-vc100-mt-gd-1_51.lib
在我的项目中链接到 boost 时，我还确保定义BOOST_ALL_DYN_LINK. 我专门使用该filesystem工具集。
当我打开时，BOOST_LIB_DIAGNOSTIC我在构建输出中看到以下消息：
1> Linking to lib file: boost_filesystem-vc100-mt-gd-1_51.lib
1> Linking to lib file: boost_system-vc100-mt-gd-1_51.lib
然而，这些很快被跟进：

不应该auto-link.hpp为我处理我的链接吗？我没有特别要求将任何内容链接到该项目，因为自动链接器似乎可以正确识别所有内容。那么我怎么会错过这些东西呢？此外，它们被声明为dllimport，所以链接器不应该让它们单独存在并期望它们在运行时被发现吗？
谢谢！
更新：我决定深入研究第二个链接器错误。它基本上是说它找不到path类的析构函数。dumpbin在库上运行后filesystem，我注意到这一行在文件中：
??1path@filesystem@boost@@QEAA@XZ (public: __cdecl boost::filesystem::path::~path(void))
但这显然与链接器正在寻找的内容不匹配，即：
"__declspec(dllimport) public: __thiscall boost::filesystem::path::~path(void)" (__imp_??1path@filesystem@boost@@QAE@XZ)
请注意，链接器正在寻找 DLL 导入版本，但库本身似乎没有提供...
