[make Error]在Ubuntu16.04 Python上安装OpenCV 3

Question

我正在尝试使用python在Ubuntu16.04上安装openCV 3.1.0。我在下面的后面得到以下错误。我最近从ubuntu14.04更新到ubuntu16.04。在ubuntu 14.04上，我有opencv 2.4.9.1，那仍然在我的ubuntu16.04上运行。

默认python是2.7.12

有人可以告诉我哪里出错了吗？ 任何线索将不胜感激。 ※我是新手

我推荐了以下网站：

我用这个选项运行cmake：-D WITH_FFMPEG = OFF它解决了我的问题。 您还可以从源代码构建ffmpeg lib来解决此问题。
