1.You need to find the library path from your system.
If the lib is not on the regular path, I suggest put it on the regular path.


whereis libnsd.so
mv your_dir/libnsd.so /usr/local/lib


Note: If the library is does not exist on your system, you should install it first.


2.Then, use ldconfig to write the path in the config file:


sudo echo "/usr/local/lib" >> /etc/ld.so.conf
sudo ldconfig


Or if you don't have root priviledge in your workstation, you can simply change user environment path:


export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
