I have included the following header files in C code using openssl libraries.
#include <sys/types.h> #include <sys/socket.h> #include <netinet/in.h> #include <arpa/inet.h> #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <errno.h> #include <string.h> #include <time.h> #ifdef __VMS #include <in.h> #include <inet.h> #else #include <netinet/in.h> #include <arpa/inet.h> #endif #include <openssl/crypto.h> #include <openssl/ssl.h> #include <openssl/err.h>
Then I compiled the program using gcc -o openssl -lssl -lcrypt openssl.c In my office, this code compiled and works fine, but on my home system (both are linux-debian 6 in the office and Ubuntu 12.04 at home), it gave the following error:

I understand that this is due to the lack of some libraries on my home PC. But can anyone tell me which libraries I need to install for this? Thanks in advance.
