我试图查看与这些错误消息相关的问题。我试图检查所有内容，但仍然没有找到错误的根源。

根据您的说法，obj 错误后跟错误 LNK2019: unresolved external symbol imp__is_CaptureVideo 在函数中引用，它的出处是什么？

我正在使用 Visual Express C++ 2010。

谢谢你。

我通过单击我的项目的属性添加了对应的库，然后将目录添加到库目录

似乎您已将“附加库目录”添加到您的 VS 项目中 - 但没有链接实际的库文件（Windows 扩展名：.lib）。我认为你所做的是

Project Properties -> Configuration Properties-> Linker -> General -> Additional Library Directories

并添加了您的第 3 方“.lib”所在的目录。但实际上这并没有链接到那个 '.lib' 文件本身（它只是添加了 VS 正在搜索链接的 .lib 文件的目录）。

尝试以下操作： Right click on your project -> Project Properties -> Configuration Properties-> Linker -> Input -> Additional Dependencies

有一个类似的列表：

'kernel32.lib;user32.lib;...;%(AdditionalDependencies)'

里面的某个地方应该会出现你的“.lib 文件”的名称。如果没有，您必须在此处添加它。即，如果您的第 3 方库的库名为“myLib.lib”，则您将在其中插入

'kernel32.lib;user32.lib;...;myLib.lib;%(AdditionalDependencies)'
