Re: [Boost-users] [Boost.MPI] question about serializing customobject

i made some progress while we were mailing between us.

first of all, im trying to see if my object can be serialized / deserialized in the common way without going into MPI yet. objects are Lattices, they have Nodes and Edges. nothing more.

this is how i've setup serialization for all three types of classes:

...

i get bad errors when deserializing, complaining about a bool and char. serializing to binlat.x...

i started debugging, and realized that the problem is completely gone when i remove "edges" from the serialization members of "Lattice" object. its weird, because "edge" is a map of and much simplier than "nodes" which does work. obviously i cannot continue without edges, so i need to fix it somehow, but i dont understand the error related to edges, maybe is something im not seeing.

Robert, that question is best looked into by you Matthias
