Question

我最近在macOS Sierra 10.12上安装了OpenCV 3.0。

安装OpenCV后，我按照其网站上的说明尝试compile the Dlib examples。我在这里遇到了构建错误，我不太确定如何修复。

错误：

[ 36%] Linking CXX executable webcam_face_pose_ex
Undefined symbols for architecture x86_64:

make[2]: *** [webcam_face_pose_ex] Error 1
make[1]: *** [CMakeFiles/webcam_face_pose_ex.dir/all] Error 2
make: *** [all] Error 2

我意识到这些是链接器错误。有人会非常友好地告诉我如何修复这些链接器错误吗？

无法安装Dlib
