fatal error: metis.h: No such file or directory
NOT sudo user
I am trying to install Metis. Since I am working on a public server, I couldn’t install it as a root user. So I have installed metis in my account /home/jd/metis.
When I try to execute something, I get
fatal error: metis.h: No such file or directory
I guess the system looks for metis.h under /usr/local/include but couldnt find it there. How do I make linux look for metis.h under /home/jd/metis/include directory? I added this path to the $PATH variable. But still the same error. Please advise.
Work with cmake. Adding include_directories("/home/xxx/metis/include")
sudo user

在编译Makefile或者CMake文件中添加opencv_highgui的链接信息，确认opencv 的lib路径是否已经添加到LD_LIBRARY_PATH中
误删/var/lib/dpkg/
首先创建一些文件
sudo mkdir -p /var/lib/dpkg/{alternatives,info,parts,triggers,updates}
从备份数据中恢复
sudo cp /var/backups/dpkg.status.0 /var/lib/dpkg/status
Now, lets see if your dpkg is working (start praying):
apt-get download dpkg
sudo dpkg -i dpkg*.deb
修复base files
apt-get download base-files
sudo dpkg -i base-files*.deb
要选Y，要选Y要选Y，否则就会出现
Setting up grub-pc (2.02~beta2-36ubuntu3.17) ...
Setting up unattended-upgrades (0.90ubuntu0.9) ...
这两关过不了的情况。
试试可以更新了不
sudo apt-get update
sudo apt-get check
