In your req2Router.cpp file, the RCVMORE socket option uses int64_t. It
changed from int64_t in zmq 2.2 to int in zmq 3.2.x and later.

I&rsquo;ve been trying to get the Paranoid Pirate &amp; Majordomo patterns working so \
that I may study their operation and implement the principles in some new development \
work I have in mind.&nbsp; What I would like to achieve is relatively \
simple. &nbsp;·&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; \
Using 0MQ networking I would like several sources (REQ?) \
of time-series data to pass any accumulated time series data history to a central \
point (ROUTER?). ·&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; \
When the accumulated data history has been passed then \
the sources would pass real time updates to the central point; as and when the new \
data are generated. ·&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; \
I would like the data flows to be asynchronous and that \
the data sources &lsquo;push&rsquo; data to the central point. ·&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; \
It is important that no data is lost due to slow joiner \
syndrome.&nbsp; It is also important that the data arrives in the correct order; \
otherwise the data will be gobbledegook. ·&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; \
A facility to detect when data sources have died/gone \
away, heartbeating. ·&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; \
Preferably to I&rsquo;d like to work in C++; it&rsquo;s \
familiar. ·&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; \
Windows 7 compatibility is essential, I am tied to using \
Windows it is where the data sources will run. &nbsp;In working through the \
problems getting Paranoid Pirate &amp; Majordomo to work &nbsp;I came to suspect that \
the problem lay in the REQ-ROUTER connection which is present in both the Paranoid \
Pirate and Majordomo patterns.&nbsp; This stackoverflow question explains some of \
approaches I&rsquo;ve tried:&nbsp; <a \
href="http://stackoverflow.com/questions/24597251/zeromq-issues-with-example-networking-patterns-paranoid-pirate-and-majordomo" \
target="_blank">Stackoverflow question</a> &nbsp;I even tried building \
CZMQ on Windows 7 so that I could try the C language original versions of the \
Paranoid Pirate &amp; Majordomo patterns.&nbsp; Have you tried building CZMQ on \
Windows; it&rsquo;s just a nightmare?&nbsp; The provided Visual Studio solution file \
just didn&rsquo;t work and the instructions are practically non-existent.&nbsp; \
Searching the internet for help found &nbsp;<a \
href="http://lists.zeromq.org/pipermail/zeromq-dev/2013-October/022981.html" \
target="_blank">rocket scientists</a> &nbsp;proposing cross compilation as the \
solution; but where to start with that?&nbsp; Really should it be that \
difficult?&nbsp; All I could see there was another month of lost weekends.&nbsp; So \
all in all that was a dead end. &nbsp;Seeking answers &amp; \
further investigating REQ-ROUTER I discovered this example: <a \
href="http://thisthread.blogspot.co.uk/2012/05/very-simple-req-router-example.html" \
target="_blank">simple req2Router example</a> and built it into a working Windows \
program. The cpp &nbsp;&amp; header file code for it are here &nbsp;<a \
href="http://pastebin.com/g66mzGm9" target="_blank">req2Router cpp file</a> and <a \
href="http://pastebin.com/yti8jUEc" target="_blank">zmq2.h header file</a> \
. &nbsp;What I discovered was that this simple req2Router program would \
function properly when linked against zeromq-2.2.0 but would not function when \
linked against zeromq-3.2.3 or zeromq-4.0.4.&nbsp; N.B. When running tests I ensured \
that the corresponding libzmq.dll file was used from the relevant version of zeromq. \
Could this be the problem in getting the Paranoid Pirate &amp; Majordomo examples to \
work; that the example code is zeromq version dependant?&nbsp; Does anyone know why \
this might be the case? What has changed between versions which would affect the \
REQ-ROUTER functionality? &nbsp;I really am stuck and \
getting tangled with this and am losing time to it. I cannot move forward with the \
plan I have in mind until I can get working implementations of Paranoid Pirate, \
&nbsp;Majordomo &amp; Asynchronous Majordomo on Windows as a foundation on which to \
build.&nbsp; It&rsquo;s doubly difficult because I want to learn from the examples \
but debugging them at the same time is testing to say the least. &nbsp;Is anyone able to help \
get these examples working with the latest versions of zeromq on Windows, not just \
for my sake but also for the next person who tries?&nbsp; Surely I can&rsquo;t be the \
only person who needs or wants to try this? &nbsp;With \
