I have made changes to 3 files : Makefile, crypt_fmt.c and john.c.
Append "-lcrypt" to line "LDFLAGS = -s", making the line reads as:
LDFLAGS = -s -lcrypt
Created a file named crypt_fmt.c
Finally added two lines (Red) to john.c:
extern struct fmt_main fmt_crypt;
but when run the cracker using ./john --test, it shows
"bash: ./john: No such file or directory"
so what should i do inorder to run the jumbo version of john the ripper in GPU?
