‘make_from_tuple’ is not a member of ‘std’

[filipesaraiva]

Hello, I built and installed paradiseo-3.0.0-beta and now I am having a problem trying to build my own code. Examples below.

CMakeList.txt:

cmake_minimum_required(VERSION 3.5)

project(knapsack-paradiseo LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

add_executable(knapsack-paradiseo main.cpp)

main.cpp:

#include <stdexcept>  // runtime_error
#include <iostream>    // cout
#include <strstream>  // ostrstream, istrstream

#include <paradiseo/eo/eo>
#include <paradiseo/eo/eoSGA.h>
#include <paradiseo/eo/ga/eoBit.h>
#include <paradiseo/eo/eoPop.h>
#include <paradiseo/eo/eoEvalFuncPtr.h>
#include <paradiseo/eo/utils/eoRndGenerators.h>

using namespace std;

typedef eoBit<double> Indi;

double binary_value(const Indi & _indi)
{
 double sum = 0;
 for (unsigned i = 0; i < _indi.size(); i++)
     sum += _indi[i];
 return sum;
}

int main()
{
    const unsigned int SEED = 42;          // seed for random number generator
    const unsigned int T_SIZE = 3;        // size for tournament selection
    const unsigned int VEC_SIZE = 8;    // Number of bits in genotypes
    const unsigned int POP_SIZE = 20;  // Size of population
    const unsigned int MAX_GEN = 100;  // Maximum number of generation before STOP
    const float CROSS_RATE = 0.8;          // Crossover rate
    const double P_MUT_PER_BIT = 0.01; // probability of bit-flip mutation
    const float MUT_RATE = 1.0;              // mutation rate

    rng.reseed(SEED);

    // Evaluation: from a plain C++ fn to an EvalFunc Object
    eoEvalFuncPtr<Indi> eval(binary_value);

    eoPop<Indi> pop;
    for (unsigned int igeno=0; igeno<POP_SIZE; igeno++)
     {
         Indi v;                    // void individual, to be filled
         for (unsigned ivar=0; ivar<VEC_SIZE; ivar++)
             {
                 bool r = rng.flip(); // new value, random in {0,1}
                 v.push_back(r);          // append that random value to v
             }
         eval(v);                                // evaluate it
         pop.push_back(v);              // and put it in the population
     }
     // sort pop before printing it!
     pop.sort();
     // Print (sorted) intial population (raw printout)
     cout << "Initial Population" << endl;
     cout << pop;


    return 0;
}

It is like the paradiseo compilation is not supporting the make_from_tuple function, despite the building and installation of the framework was correct.

Well, any idea about what is happening here?

All the best;
