Failed to add /run/systemd/ask-password to directory watch: No space left on device

Solution :

echo 1048576 > /proc/sys/fs/inotify/max_user_watches

The long-term fix is to edit the file /etc/sysctl.conf to include the line:

fs.inotify.max_user_watches=1048576

Reload Kernel.

sysctl -p

Reload settings from all system configuration files.

Type the following command to reload settings from config files without rebooting the box:

sysctl --system

Error: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found

Solution :
Your gcc is older and you need to upgrade new.

If you are using centos, here is the procedure to upgrade gcc

wget https://ftp.gnu.org/gnu/gcc/gcc-8.1.0/gcc-8.1.0.tar.gz
yum install libmpc-devel mpfr-devel gmp-devel zlib-devel*
./configure --with-system-zlib --disable-multilib --enable-languages=c,c++
make -j 8
make install
