CUPS installing using repository

Question

I want to get printer state from CUPS. To do that , I am trying to customize CUPS's source code. So I can send a message to my front-end.

I have downloaded CUPS repository from gitub Apple's Cups repo. Then unzip it and ran

./configure

I am getting following error.

auth.c: In function ‘cups_crypt’: auth.c:2017:5: error: unknown type name ‘_cups_md5_state_t’ _cups_md5_state_t state; /* Primary MD5 state info / ^ auth.c:2018:5: error: unknown type name ‘_cups_md5_state_t’ _cups_md5_state_t state2; / Secondary MD5 state info */

If I just use yum install cups it works fine.

What went wrong here?

Thanks in advance.
