Я использую библиотеку ускорения C++ 1.6.3 для сериализации и сохранения в текстовом файле основного класса игры с различными классами, прикрепленными внутри нее в качестве указателей и ссылки, массивы и основные типы переменных, проблема, когда я загрузить файл, он выходит из строя дает этот вывод:CRASH: ошибка сегментации: ускорение загрузки сериализации - вызывающий конструктор с нулем
Assertion failed: register_type(bpis_ptr->get_basic_serializer()) == cid, file libs\serialization\src\basic_iarchive.cpp, line 454
дело в том, что этот класс похож на другие классы сериализовать и нет никаких ошибок с ними ,
Для сериализации это то, что я делаю, после форсирования :: инструкции сериализации: 1) В базовых классах: добавить класс друга для доступа к сериализации, а функция для сериализации, например:
class BJShoe
{
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive & ar, const unsigned int file_version)
{
ar & BOOST_SERIALIZATION_NVP(totalCards);
ar & BOOST_SERIALIZATION_NVP(cards);
ar & BOOST_SERIALIZATION_NVP(numCards);
}
protected:
int totalCards[10],
cards[10],
numCards;
}
так, для основного класса у меня есть что-то вроде этого:
class Game {
int numDecks;
bool hitSoft17;
bool doubleAnyTotal;
bool double9;
bool doubleSoft;
bool doubleAfterHit;
bool doubleAfterSplit;
bool resplit;
bool resplitAces;
bool lateSurrender;
int dealerSpeed;
BJStrategy maxValueStrategy;
Progress progress;
// Release all objects on exit
BJRules *rules;
Player *strategy;
Hand *dealer;
Probabilities *dealerProbabilities;
Shoe *shoe;
BJShoe *distribution;
PlayerHand *tempHand;
//counters and game-loop vars
int lastWager;
int balance;
Card tempCard;
PlayerHand playerHands[4];
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive &ar, const unsigned int version)
{
ar.template register_type<BJShoe*>();
ar.template register_type<PlayerHand*>();
//etc.
ar.template register_type<BJShoe>();
ar.template register_type<PlayerHand>();
cout << "numDecks\n";
ar & BOOST_SERIALIZATION_NVP(numDecks);
cout << "hitSoft17\n";
ar & BOOST_SERIALIZATION_NVP(hitSoft17);
cout << "doubleAnyTotal\n";
ar & BOOST_SERIALIZATION_NVP(doubleAnyTotal);
cout << "double9\n";
ar & BOOST_SERIALIZATION_NVP(double9);
cout << "doubleSoft\n";
ar & BOOST_SERIALIZATION_NVP(doubleSoft);
cout << "doubleAfterHit\n";
ar & BOOST_SERIALIZATION_NVP(doubleAfterHit);
cout << "doubleAfterSplit\n";
ar & BOOST_SERIALIZATION_NVP(doubleAfterSplit);
cout << "resplit\n";
ar & BOOST_SERIALIZATION_NVP(resplit);
cout << "resplitAces\n";
ar & BOOST_SERIALIZATION_NVP(resplitAces);
cout << "lateSurrender\n";
ar & BOOST_SERIALIZATION_NVP(lateSurrender);
cout << "dealerSpeed\n";
ar & BOOST_SERIALIZATION_NVP(dealerSpeed);
cout << "maxValueStrategy\n";
ar & BOOST_SERIALIZATION_NVP(maxValueStrategy);
cout << "progress\n";
ar & BOOST_SERIALIZATION_NVP(progress);
cout << "rules\n";
ar & BOOST_SERIALIZATION_NVP(rules);
cout << "strategy\n";
ar & BOOST_SERIALIZATION_NVP(strategy);
cout << "dealer\n";
ar & BOOST_SERIALIZATION_NVP(dealer);
cout << "dealerProbabilities\n";
ar & BOOST_SERIALIZATION_NVP(dealerProbabilities);
cout << "shoe\n";
ar & BOOST_SERIALIZATION_NVP(shoe);
cout << "distribution\n";
ar & BOOST_SERIALIZATION_NVP(distribution);
cout << "tempHand\n";
ar & BOOST_SERIALIZATION_NVP(tempHand);
cout << "lastWager\n";
ar & BOOST_SERIALIZATION_NVP(lastWager);
cout << "balance\n";
ar & BOOST_SERIALIZATION_NVP(balance);
cout << "tempCard\n";
ar & BOOST_SERIALIZATION_NVP(tempCard);
/*for (int i = 0; i < 4; i++) {
ar & BOOST_SERIALIZATION_NVP(playerHands[i]);
cout << "playerHands["<<i<<"]\n";
}*/
ar & BOOST_SERIALIZATION_NVP(playerHands);
cout << "playerHands\n";
}
}
2) в дочерних классах, сделать то же самое, как (1) и добавить функцию base_object, пример для обуви, который наследуется от BJShoe:
boost::serialization::base_object<BJShoe>(*this);
3) Экспорт классов в CPP, например:
BOOST_CLASS_EXPORT(Shoe)
BOOST_CLASS_EXPORT(BJShoe)
4) функция для сохранения
void Game::save(const char* filename)
{
ofstream ofs(filename);
if (!ofs.good()) return;
text_oarchive oa(ofs);
//register all the classes, example:
oa.register_type<Shoe>();
oa.register_type<BJShoe>();
oa.register_type<Game>();
oa << boost::serialization::make_nvp("game",instance);
ofs.close();
}
) функция от нагрузки 5:
void Game::load(const char* filename)
{
ifstream ifs(filename);
if (!ifs.good()) return;
text_iarchive ia(ifs);
//register all the classes, example:
ia.register_type<Shoe>();
ia.register_type<BJShoe>();
ia.register_type<Game>();
ia >> boost::serialization::make_nvp("game",instance);
ifs.close();
}
6) вызов save ("play.data"); нагрузка ("play.data"); ведет программу к аварии, это журнал:

я не понимаю, если это что-то связано с конструкторами или функции сериализации, потому что выглядит, как он пытается инициализировать нулем, верно?
