Gobot OpenCV 失败

Question

我正在尝试运行来自 GoBot Go Lang OpenCV 的 OpenCV 测试应用程序。我尝试运行该页面中给出的示例代码，但我得到的只是一个错误：

我做错了什么？我已经安装运行 C++ OpenCV 之前

Answer 1

跟进评论；我给了 gobot 另一个样本 opencv_face_detect，它对我有用。尽管您发布的示例 link 似乎是 faulty/outdated.

这是在 OS X 10.11.5 和 go1.6.2 darwin/amd64 上。

这是我执行的步骤；

安装opencv；

brew tap homebrew/science && brew install opencv
安装gobot和go-opencv；

go get github.com/hybridgroup/gobot && go get github.com/lazywei/go-opencv
运行 face_detect 示例位于 "github.com/hybridgroup/gobot/examples"，别忘了微笑！

go run opencv_face_detect.go
