Thank you for your help. :) It compiled without issue but now I'm
having another problem generating the charset files.
Specifically, my john.pot is composed nohash:password pairs which I
constructed from all.chr and the Openwall wordlist collection ( just
recently bought ). In this case I used the huge mangled.lst file from
the iso image.
When I run ./john --make-charset=new.chr I get this error :
Loaded 0 plaintexts, exiting...
I am at a loss as to what the problem is.
