How can I serialize an std::vector with boost::serialization?

Question

class workflow {

private:
friend class boost::serialization::access;

template
void serialize(Archive & ar, const unsigned int version)
{
  ar

Just to add a generic example to this question. Lets assume we want to serialize a vector without any classes or anything. This is how you can do it:

#include 
#include 

// include input and output archivers
#include 
#include 

// include this header to serialize vectors
#include 

using namespace std;



int main()
{

  std::vector v = {1,2,3.4, 5.6};

  // serialize vector
  {
    std::ofstream ofs("/tmp/copy.ser");
    boost::archive::text_oarchive oa(ofs);
    oa & v;
  }

   std::vector v2;

   // load serialized vector into vector 2
   {
     std::ifstream ifs("/tmp/copy.ser");
     boost::archive::text_iarchive ia(ifs);
     ia & v2;
   }

   // printout v2 values
   for (auto &d: v2 ) {
      std::cout << d << endl;
   }


  return 0;
}

Since I use Qt, this is my qmake pro file contents, showing how to link and include boost files:

TEMPLATE = app
CONFIG -= console
CONFIG += c++14
CONFIG -= app_bundle
CONFIG -= qt

SOURCES += main.cpp


include(deployment.pri)
qtcAddDeployment()

INCLUDEPATH += /home/m/Downloads/boost_1_57_0


unix:!macx: LIBS += -L/home/m/Downloads/boost_1_57_0/stage/lib -lboost_system
