Question

我尝试使用MinGW和Netbeans运行示例Dlib代码。但是我遇到了编译错误。

遵循的步骤：

1.从Dlib网站下载Dlib包。

2.在c ++编译器设置中包含根文件夹（Dlib），并在编译器附加标志中设置-std = c ++ 11。

3.从Dlib文件夹示例中复制样本。

4.Compiled。

编译代码时出现Bellow错误。给我执行Dlib示例代码的简单步骤（例如Dlib中的示例中的face_detection_ex代码）

如果您使用的是Linux您需要将libvl.so添加到链接器设置中。在64位系统中，您可以在/ vlfeat / bin / glnxa64 /中找到此文件。

如何在构建Dlib代码时解决编译错误。
