deque avec unique_ptr de wrapper de threads

Question

Je suis en train de compiler ceci pour un projet incorporé, mais il échoue toujours à compiler. Le code compile correctement avec clang sur mac. L'exemple ajoute deux threads à un conteneur deque, les joint et les supprime du conteneur. MISE À JOUR

class th { 
    public: 
     void func() { 
      sleep(3); 
      *this->progress = 100; 
     } 

     th(int* prog) : 
      progress(prog), 
      m_thread(std::thread(&th::func, this)) {}; 

     th(th const& other) = delete; 
     th(th && other) = default; 
     th& operator=(th const& other) = delete; 
     th& operator=(th &&) = default; 

     void join() { m_thread.join(); } 
     int *progress; 

    private: 
     std::thread m_thread; 
}; 

int main(void) { 

     std::vector<int> progress; 
     progress.push_back(-1); 
     progress.push_back(-1); 

     std::deque<std::unique_ptr<th>> deq; 

     std::cout << "progress[0]:" << progress[0] << std::endl; 
     std::cout << "progress[1]:" << progress[1] << std::endl; 

     std::cout << "executing threads..." << std::endl; 

     for(size_t i = 0; i < 2; ++i) { 
      deq.push_back(std::unique_ptr<th>(new th(&progress[i]))); 
     } 

     while(true) { 
      std::cout << "SIZE:" << deq.size() << std::endl; 

      if(deq.size() == 0) 
       break; 

      for (std::deque<std::unique_ptr<th>>::iterator it = deq.begin(); it != deq.end(); it++) { 
       //std::cout << (*it)->progress << std::endl; 
       if(*((*it)->progress) == 100) { 
        std::cout << "JOIN & DELETE" << std::endl; 
        (*it)->join(); 
        deq.erase(it); 
       } 
       else { 
        std::cout << "STILL RUNNING" << std::endl; 
       } 
        //std::cout << *((*it)->progress) << std::endl; 
      } 
      sleep(1); 
     } 

    exit(EXIT_SUCCESS); 
}

Le problème est que votre classe est non mobile. Je peux comprendre que puisque la classe a un std::thread vous voudriez éviter le comportement de copie par défaut, mais je ne vois aucune raison que la classe devrait être non-mobile. Si vous activez la construction et l'affectation du mouvement your code works fine.

th(th const& other) = delete; 
th(th && other) = default; 
th& operator=(th const& other) = delete; 
th& operator=(th &&) = default; 

Aussi je vous comment ajuster aurait été la construction de ces objets à la

for(size_t i = 0; i < 2; ++i) { 
    deq.push_back(std::make_unique<th>(&progress[i])); 
}
