You are preparing a new set of shared libraries in /usr/local/applib and you have written and
compiled some code that uses these libraries. You have already performed an Idconfig, however
the system still cannot find the shared libraries. What is most likely the cause of this?

A.
You used the wrong compil|er.

B.
You did not update your PATH variable.

C.
You compiled the code with wrong library.

D.
You forgot to put the library path in ld.so.conf.

Explanation:
/etc/ld.so.conf File containing a list of colon, space, tab, newline, or comma
spearated directories in which to search for libraries. So you should specify the path the libraries
in/etc/ld.so.conf file.
