error: ‘NppiGraphcutState’ has not been declared
error: ‘NppiGraphcutState’ does not name a type

edit the graphcuts.cpp file

change the

#include "precomp.hpp"
#if !defined (HAVE_CUDA) || defined (CUDA_DISABLER)

to

#include "precomp.hpp"
#if !defined (HAVE_CUDA) || defined (CUDA_DISABLER)  || (CUDART_VERSION >= 8000)

• other

modules/gpu/src/nvidia/core/NCVPixelOperations.hpp(51): error: a storage class is not allowed in an explicit specialization

edit the NCVPixelOperations.hpp

为了使用起来方便，装了Ubuntu中文版，自然在home文件里用户目录的“桌面”、“图片”、“视频”、“音乐”……都是中文的。很多时候都喜欢在桌面上放一些要操作的文件，linux里命令行操作又多，难免会用命令行操作桌面上的东西，那么就要 “cd 桌面”，打“桌面”的时候要输入法切换，麻烦……所以就想办法把用户目录下的路径改成英文，而其他的中文不变， 方法如下：

 

　　打开终端，在终端中输入命令:

　　export LANG=en_US

　　xdg-user-dirs-gtk-update

 

　　跳出对话框询问是否将目录转化为英文路径,同意并关闭.

 

　　在终端中输入命令:

　　export LANG=zh_CN

 

　　关闭终端,并重起.下次进入系统,系统会提示是否把转化好的目录改回中文.选择不再提示,并取消修改.主目录的中文转英文就完成了.

===============================================================================  

　　在有些linux发行板中，上面的命令无法使用，不过我们可以动过手动修改的方式达到，具体方法路下：

找到～/.config/user-dirs.dis文件

（注：~/代表当前用户目录   .config是个隐藏文件）

将该文件中的中文改成对应的英文

 

再在～/目录下创建对应的英文文件夹，重启就可以了
