ZMQ Compilation problems for C++ examples - zeromq

Question

I am trying to compile the ZMQ C++ source code examples provided at zmq.org (i.e. github.com/imatix/zguide.git). My OS is xubuntu and I installed ZMQ prerequisites which are libtool, autoconf, automake and uuid-dev package properly. I installed czmq as well. Compilation and linking of ZMQ itself was fine and libs are located properly under /usr/local/bin. Nevertheless, I am getting below compilation errors. Googling did not help much and I wonder if anyone knows a quick solution to these errors, which originates from the missing header file zmq.hpp. Thanks in advance.
$./build all

Answer 1

It looks zmq.hpp has been moved to another git repository beginning with ZMQ 3.2 which is available at https://github.com/zeromq/cppzmq. I have clonned this to same place where a previously extracted the ZMQ's tar ball. Then I created a symbolic link to zmq.hpp from the examples's C++ directory. Then examples compiled fine.
