scalbf-wur's Issues

dockerfile

RUN ./install_scidb.sh

cannot access *.deb

echo “deb https://downloads.paradigm4.com/ ubuntu14.04//3rdparty/“ >> /etc/apt/sources.list 这行代码执行后运行apt-get update认定sources.list加入的这一行语法不对！！

解决方法

可以更正为
echo "deb https://downloads.paradigm4.com/ ubuntu14.04/3rdparty/" >> etc/apt/sources.list.d/scidb.list

通过apt-cache search scidb来查看

install_scidb.sh中scidb_libboost的一些源不对

文件/install/install_scidb.sh中
deb https://downloads.paradigm4.com/ ubuntu14.04/3rdparty/
多了个空格，导致无法下载scidb的相关联的第三方库文件，正确地址应该是
https://downloads.paradigm4.com/ubuntu14.04/3rdparty/

your kernel does not support swap limit capabilities or the cgroup is not mounted

Adjust memory and swap accounting
When users run Docker, they may see these messages when working with an image:

WARNING: Your kernel does not support cgroup swap limit. WARNING: Your
kernel does not support swap limit capabilities. Limitation discarded.
To prevent these messages, enable memory and swap accounting on your system. To enable these on system using GNU GRUB (GNU GRand Unified Bootloader), do the following.

Log into Ubuntu as a user with sudo privileges.

Edit the /etc/default/grub file.

Set the GRUB_CMDLINE_LINUX value as follows:

GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"
Save and close the file.

Update GRUB.

$ sudo update-grub
Reboot your system.

docker run 运行后马上退出

docker run 参数包含 -it
