doubt regarding "WITH_TCPWRAPPER"

[sivasankari]

Hello,
when i link dcmtk with my application(which has the implementation for using dcmtk worklist service ,using findscu) in linux,
i got the following errors,

When i included the libraries ssl and crypto (from openssl0.9.7d) to my CmakeLists.txt, my errors reduced.

I think it is not including the system headers tcpd.h and syslog.h.
If yes, how to rectify the problem. Please correct me if i am wrong.

Thanks in advance,

You should either install "Wietse Venema's TCP wrappers library (libwrap)" and enable support for it as described in the INSTALL file, or you should disable this library completely (#undef WITH_TCPWRAPPER).
