Cannot find libcrypto library error

When i am trying to compile a C code which uses openssl 'crypto' library functions with comand line -lcrypto with gcc 4.4.3 it gives an error

`@ubu:$ gcc -ggdb aes_m.c -Werror -Wall -I /usr/local/ssl/include/ -lcrypto -o aes
 /usr/bin/ld: cannot find -lcrypto
 collect2: ld returned 1 exit status`

what can be the reason for this??

I have already gone through this discussion ld cannot find an existing library but that does not help.

locate command results in

$ locate libcrypto

Can someone please help on this or point out any mistake i am doing

@ Daniel Roethlisberger tried using the -L flag but that resulted in these errors
