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

B.
You did not update your PATH variable.

C.
You compiled the code with wrong library.

D.
You used the wrong compil|er.

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