I'm using the xml archiving classes, which require the boost macro to be used, otherwise compilation fails. Even if applying the changes you recommended would work, that would mean that I can no longer store my serialized data as xml. But, I'll take and try most advice at this point and I can sadly report that the result is the same using the text archiving classes from boost and removing the macro as suggested. As soon as I enter the serialize function declared in my class via the
operator (which I take it boost overloads), the remaining data in aStream gets messed up for reasons that are still beyond me.

Hello to you,
I wonder if you might be able to solve this conundrum I've been pondering. The boost (1.51) serialization library is giving me some trouble. I've been battling back and forth with the library, and I'm beginning to think I'm missing some key element.
At first, I had issues to just getting things written out to a file without crashes. As far as I could tell, this particular problem was compounded by the fact, that I tried to simplify my code by just writing a single primitive referenced by a pointer to an object containing said primitive. As I've since come to learn, serializing pointed-to primitives is apparently not trivial.
I have since, gotten the serialization class to properly write out a few simple member primitives from my class, but when I read them back using the exact same function, it seems as though a lot - if not all - of the pre-existing data in the object, which I am not serializing, gets overwritten.
As far as I have been able to tell from the tutorials, I am doing everything exactly by the book. I was also concerned that maybe boost doesn't allow partial serialization, but this shouldn't be an issue either as far as I can tell. I must be making some sort of colossal mistake that I just cannot see.
My in and out code is fairly straight forward:
std::string streamPath = PTMFilePath.string(); std::ifstream ifs(streamPath); boost::archive::xml_iarchive ia(ifs);
ia >> BOOST_SERIALIZATION_NVP(aStream);
try
ia >> aStream;
-----
std::string streamPath = PTMFilePath.string(); std::ofstream ofs(streamPath); boost::archive::xml_oarchive oa(ofs);
oa << BOOST_SERIALIZATION_NVP(aStream);
oa << aStream;
------
My serialization function:
template<class Archive> void serialize(Archive &ar, const unsigned int file_version) { ar & BOOST_SERIALIZATION_NVP(nrOfSamples); }
------
aStream is a pointer to a custom class, where I have allowed boost access. I am really confused as to what is causing this. Both pointed to data and regular primitives in the aStream class are wiped/altered as soon as the program enteres the serialize function, and even before the actual data seems to be read.
I must be overlooking something really basic here. I hope someone can whack me with the solution stick...
Thanks, Lasse
