You need to add the path to the directory the file is in, in the ‘ld.so.conf’ file. If for example the file is located under “/usr/local/lib” directory, execute ldconfig

1	# vi /etc/ld.so.conf

and add the following at the bottom of the file

	/usr/local/lib

Save the file and for the new changes to take effect, execute

ldconfig
