This was posted to the Boost users list recently by someone attempting to get
it working with VC++ 7.
#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);
}

That'd be good.

If I compile it with either LyX's copy of the boost libraries or with
version 1.26 I get the same sort of messages I posted earlier.
This is with DEC cxx v6.1.
