ubuntu卸载opencv

opencv安装后，即使编译成功，而在调用处理图像视频时，尤其访问摄像头时，会出现错误，其实错误是安装opencv前，没有安装好必要的依赖库，而这需要安装顺序的，所以出现这类问题必须卸载重装。

本人在不同平台重装opencv好多次，卸载opencv的步骤如下：

1、在自己编译的文件夹下，执行此命令，本人的是 /home/guit/opencv3.0/build/     

$ make uninstall

2、回到 /home/guit/opencv3.0/下

$ cd ..

3、删除build   

$ sudo rm -r build

4、删除其余的

$ sudo rm -r /usr/local/include/opencv2 /usr/local/include/opencv /usr/include/opencv /usr/include/opencv2 /usr/local/share/opencv        /usr/local/share/OpenCV /usr/share/opencv /usr/share/OpenCV /usr/local/bin/opencv* /usr/local/lib/libopencv
