推荐答案

如果您还没有这样做，您将需要构建您将链接到的库，它们位于 \libusb-1.0.18-rc1\msvc.那里有多个项目，具体取决于您的 Visual Studio 版本以及您想要 DLL 还是静态 LIB 文件.

If you havne't done so already you will need to build the libraries you will be linking to, they are located in \libusb-1.0.18-rc1\msvc. There are multiple projects there depending on your Visual Studio version and whether you want a DLL or a static LIB file.

无论哪种情况，您都需要右键单击您的项目，然后在 Configuration Properties -> Linker -> Input -> Additional Dependencies 下添加对您创建的 LIB 文件的引用.如果您链接到已完成的静态 LIB 文件，它会将代码构建到您的可执行文件中.如果您要链接到 DLL 的 LIB 文件，请确保该 DLL 在您的执行路径中可用.无论哪种情况，这都应该解决您未解决的外部问题.

In either case you will need to right click on your project, then under Configuration Properties -> Linker -> Input -> Additional Dependencies add a reference to the LIB file you created. If you are linking to the static LIB file you're done, it will build the code in to your executable. If you're linking to the LIB file for the DLL make sure the DLL is available in your execution path. In either case this should resolve your unresolved externals.
