I'm doing user authendication in my FTP server..

I used crypt() function to encrypt the user password. So that i
can compare with the encripted password in the database.

but, while executing the program, it shows an error as,

UNDEFINED REFERENCE TO CRYPT() FUNCTION.

Are you also linking against libcrypt.so, i.e. have '-lcrypt' in
the command you compile (link, to be precise) your program with?

But i included "unistd.h"..

I just found that on my system using (as required according to the
man page for crypt)

#define _XOPEN_SOURCE
#include <unistd.h>

or just (as according to SUSv3)

#include <unistd.h>

does _not_ make the compiler find the declaration of crypt(3), I
instead had to include <crypt.h>. Does anybody know what could be
the reasons for this?
