如何解决构建 Dlib 代码时的编译错误

Question

我试图使用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软件包。

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 文件夹示例中复制示例。

4.编译。

编译代码时出现波纹管错误。给我执行 Dlib 示例代码的简单步骤（例如 Dlib 示例中face_detection_ex代码）

如果你在 Linux 中，你需要将 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。
