When I use the command gcc teste.c -lssl -o teste:
Error:

Another attempt:
ubuntu@omap:~/arquivos$ gcc rsa.c -Wl, -lssl, -lcrypto -o teste
/usr/bin/ld: cannot find : No such file or directory
/usr/bin/ld: cannot find -lssl,
collect2: ld returned 1 exit status
Any idea?
I haven't found the libssl.so in my directory /usr/lib.
Thanks everybody.
