Daryle, thanks for your response. The code does work on VC6. Here is the crc.hpp related errors I get when I compile with VC7. Thanks!

I have the following code that doesn't compile using VC 7.0. I am getting many errors in crc.hpp. Am I missing something simple here? I have just glanced at the manual, so please be gentle with the RTFM responses :)

TIA, David Brownell

#include<iostream> #include "boost\crc.hpp"

int main(void) { const unsigned char DATA[] = { 1, 2, 3, 4, 5 };

boost::crc_32_type crc;

crc.reset(); crc.process_bytes(DATA, sizeof(DATA) / sizeof(*DATA));

std::cout << crc.checksum() << std::endl; return(true); }

I ran it just fine (and got "1191942644" printed). There may be some VC++ 7 quirks. Did you try it with VC++ 6?
