Is this correct?


Yes

If you want to send complex data structures, portably between different
programming language environments and processor architectures.
This is not a goal of ZeroMQ and is explicitly left to other libraries and
tools.

| 2.  Why use memcpy is bad or not suited?

http://en.cppreference.com/w/cpp/algorithm/copy
http://en.cppreference.com/w/cpp/algorithm/copy_n

are better alternatives in C++ and as, or more efficient than ::memcpy
(they in fact delegate, as inline code to ::memcpy if that is the fastest
way to perform the copy).

your example would read -

#include 

...

std::copy_n(result.c_str(), result.size() + 1, request.data());

OR

std::copy(result.begin(), result.size(), request.data());

Please consult

your operating system's package manager, where you may find a prepackaged
version of Boost for your platform

[zeromq-dev] Building C++ binding zmq - zmqpp step

[Bernardo Augusto García Loaiza]

Hi ZMQ people.

I am building the c++ binding zmq and I have this inconvenient which I've
entered as a issue  in the
zmqpp repository  

In the building process,  I have the problem

++  -o ./build/max-g++/zmqpp-tests
./build/max-g++/obj/tests/test_inet.o
./build/max-g++/obj/tests/test_z85.o
./build/max-g++/obj/tests/test_context.o
./build/max-g++/obj/tests/test_message.o
./build/max-g++/obj/tests/test_auth.o
./build/max-g++/obj/tests/test_actor.o
./build/max-g++/obj/tests/test_load.o
./build/max-g++/obj/tests/test_proxy.o
./build/max-g++/obj/tests/test_loop.o
./build/max-g++/obj/tests/test_socket_options.o
./build/max-g++/obj/tests/test_socket.o
./build/max-g++/obj/tests/test_reactor.o
./build/max-**g++/obj/tests/test_sanity.o
./build/max-g++/obj/tests/test_message_stream.o
./build/max-g++/obj/tests/test_poller.o -L./build/max-g++ -lzmqpp
-lboost_unit_test_framework -lpthread -lzmq
/usr/bin/ld: cannot find -lboost_unit_test_framework
collect2: error: ld returned 1 exit status
Makefile:195: recipe for target 'zmqpp-tests' failed**
make: *** [zmqpp-tests] Error 1

How to can I add or install or setup the -lboost_unit_test_framework library
? ... just in case that I am in right in my appreciation problem ...
