在VC++2010 Express中生成项目时出错

Error when building a project in VC++ 2010 Express

本文关键字：项目 出错 VC++2010 Express      更新时间：2023-10-16

我试图了解与这些错误消息相关的问题是什么。我试着检查了所有的东西，但仍然没有找到错误的来源。

根据您的说法，obj错误后面跟着错误LNK2019：函数中引用的未解析外部符号imp__is_CaptureVideo，它的来源是什么？

我正在使用Visual Express C++2010。

谢谢。

我已通过单击属性添加了相应的库然后，将目录添加到Library Directories

看起来你已经将"附加库目录"添加到了你的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

并添加了您的第三方".lib"所在的目录。但事实上，它本身并没有链接到".lib"文件（它只是添加了VS正在搜索链接的.lib文件的目录）。

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

有这样一个列表：

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

还有一些人应该在里面出现你的".lib文件"的名称。如果没有，你必须把它添加到那里。也就是说，如果你的第三方库的库名为"myLib.lib"，你会在那里插入

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