I visited this link http://www.schneier.com/blowfish-download.html
and download the c++ code from "author unknown" and want to use it. Then i split it into 3 files. I try to compile it , but it fails with comments
ubuntu@ubuntu:~/program$ g++ -o BFtest BFtest.c
In file included from BFtest.c:7:
blowfish.h:29: error: redefinition of ‘struct WordByte’
blowfish.h:20: error: previous definition of ‘struct WordByte’
please advise. tks.
