Hi Kind-DaniWebbers, How do you initialise a boost::archive:binary_oarchive in a different place to where you declare it? So: class CBase { std::ofstream m_ofs; boost::archive:binary_oarchive m_binOA(); // <== default constructor virtual void Open(std::string& s) = delete; }; class CDerived : CBase { void Open(std::string& s) override { CBase::m_ofs("filename.bin", std::ios::binary); CBase::m_binOA(CBase::m_ofs, /*flags*/); …
