Estou recebendo um erro de vinculador de referências indefinidosó ao vincular arquivos de objetos otimizados,não ao vincular arquivos de objetos não otimizados. Eu não entendo o que o problema é ou poderia ser.

Alguma ideia?

[PROBLEMA FIXO COM FUNÇÃO showDecimals ()]

O arquivo COMPASS.h inclui este modelo de classe:

template<class T> class VisitedSet {
public:
    VisitedSet(const T& soln); 
    int getSize();
    void addSolution(const T& soln);
    void evaluate();
    void sample(const int& numNewSolutions, Constraints& space);
    void CSBiased_generateDistribution();
    void constructMPA(Constraints& space);
    vector<T> vec;
    double bestValue;
    int bestIndex;

    /* used to implement biased coordinate sampling */
    double CSBiased_coefficient;
    vector< vector<double> > lastSampledPoints;
    vector<int> lastSampledPointsIndex;
    vector< vector<double> > newSampledPoints;
    vector<int> newSampledPointsIndex;
    vector<double> CSBiased_distribution;

private:
    int iteration;
    int dimension; 
    int SAR(); // simulation allocation rule
};

E o COMPASS.cpp inclui o seguinte código:

template<class T>
int VisitedSet<T>::getSize() {
    return vec.size();
}

Os arquivos logging.cpp incluem o seguinte código:

#include "COMPASS.h"
void LOG_COMPASS_display_points_MATLAB(const int& iteration, VisitedSet<Policy>& visited) {
    cout << "points{"<<iteration+1<<"} = [\n"
         << visited.vec[visited.bestIndex].x[0] << "\t" <<     visited.vec[visited.bestIndex].x[1] << "\t" << visited.vec[visited.bestIndex].meanQALY() << ";" << endl;
for(int i=0; i<visited.getSize(); i++) {
    if(i != visited.bestIndex)
        cout << visited.vec[i].x[0] << "\t" << visited.vec[i].x[1] << "\t" << visited.vec[i].meanQALY() << ";" << endl;
}
cout << "];\n";
