running example

[Daniel Cegiełka]

Hi, 

I try to run the example from the documentation, but I get errors.

#include <iostream>

#include <string>

#define HFFIX_NO_BOOST_DATETIME

#include "hffix.hpp"

int main()

{

char buffer[512];

hffix::message_writer writer(buffer, buffer + 512);

writer.push_back_header();

writer.push_back_string(hffix::tag::MsgType, "0");

writer.push_back_string(hffix::tag::SenderCompID, "AAAA");

writer.push_back_string(hffix::tag::TargetCompID, "BBBB");

writer.push_back_int(hffix::tag::MsgSeqNum, 1);

//writer.push_back_timestamp(hffix::tag::SendingTime, boost::posix_time::microsec_clock::universal_time());

writer.push_back_trailer();

std::cout.write(writer.message_begin(), writer.message_size()) << std::endl;

std::cout << "Wrote " << writer.message_size() << " bytes to buffer." << std::endl;

return 0;

}

Hi Daniel,

Sorry for the delay in responding, I've been on holiday.

I just released a new HFFIX version 1.4 which should solve your
compile errors.

Thanks for the bug report!

I fixed this error now - you need to add:

# include <stdexcept>

on Linux is also a different error (g++) but to fix it, enough to add:

# include <cstddef>

btw. On linux it doesn't print the separator (SOH with
std:cout.write()). Is this a bug?

best regards,
daniel

Hi Daniel,

Thanks for the bug report! I probably forgot to include <stdexcept> in
hffix.hpp because I was including it from somewhere else, I'll look
into that.

hffix::message_writer writes the SOH characters that FIX 4.2 uses to
delimit fields, is that what you're talking about? Could you be more
specific?

Oh, I think I know what you mean: if you try to print an SOH character
to the terminal in Linux, then nothing will appear. That's just
because the terminal doesn't render the SOH character. The
hffix::message_writer is writing the SOH characters to the buffer that
you supply, but if you want to see the non-printing characters in that
buffer, you'll have to look at it some way other than sending it
straight to the terminal.

You could, for instance, pipe your output through tr and replace all
non-printing control characters with a '|'. So if you have a program
called 'hffixtest' that outputs the FIX buffer to standard out, you
could so something like this:

# ./hffixtest | tr [:cntrl:] '|'
8=FIX.4.2|9=0051|35=0|49=AAAA|56=BBBB|34=1|52=20110130-19:14:21.056|
10=049|

Best,
