I am trying to serialize a class that contains a std::chrono::system_clock::time_point with boost::serialize.
template <class Archive> void serialize(Archive& ar, unsigned int version) {
ar & timePoint_;
}
However I get the error:
Error 1 error C2039: 'serialize' : is not a member of 'std::chrono::time_point<_Clock>' c:\boost_1_54_0\boost\serialization\access.hpp 118
How do I fix this?
Use
boost::serialization::make_binary_object(void * t, size_t size);
from
boost/serialization/binary_object.hpp wchich can be used like this:
std::chrono::system_clock::time_point tp;
ar & boost::serialization::make_binary_object(&tp, sizeof(tp));
I managed to get it to work using the following intrusive function (in the class which has the timepoint_ as a member function)
template <class Archive> void serialize(Archive& ar, unsigned int version) {
char * ptr = reinterpret_cast<char *>(&timePoint_);
for( int i = 0; i < sizeof(timePoint_); ++i)
ar & ptr[i];

}
