$ ./john --format=crypt mypasswd
Unknown ciphertext format name requested

$ ./john --format=sha512crypt mypasswd
Unknown ciphertext format name requested

/usr/bin/ld: cannot find -lssl
/usr/bin/ld: cannot find -lcrypto
/usr/bin/ld: cannot find -lz

I would guess not.

$ sudo apt-get install libssl-dev

$ make clean generic

$ cd ../run
$ ./john mypasswd
Loaded 5 password hashes with 5 different salts (sha512crypt [32/32])
games            (games)

Problem solved - thank you very much.
