I tried to compile your example and I had a couple of problems: a) DLL_EXPORT wasn't defined - I defined it as nothing b) NodeMap wasn't declared anywhere - I'm not sure what it should be c) The following statement is very suspicious: archiveFile >> *_nodes; Since _nodes is declare as const *- *_nodes is a const and can't be loaded. Perhaps something similar to the following might be what you're looking for: // this method compiles fine void save( const std::string & filename, const std::map > & nodes ){ std::ofstream outFile; outFile.open(filename.c_str(), std::ios::binary); boost::archive::text_oarchive archiveFile(outFile); archiveFile << nodes; } // fails on compile with STATIC_ASSERTION_FAILURE void load( const std::string & filename, std::map > & nodes ){ std::ifstream inFile; inFile.open(filename.c_str(), std::ios::binary); boost::archive::text_iarchive archiveFile(inFile); archiveFile >> nodes; } int main(){ std::map > nodes; save("name", nodes); load("name", nodes); } Robert Ramey cheesy4poofs wrote:

I've read over the compile time trap section of the docs, but I still can't get my serialization code to compile. The code to save my std::map compiles, but the code to load the map asserts on the compile. As far as I can tell, I'm not doing anything wrong (save with const ref, load with non-const ref).

I will try to summarize my serialization code below:

#include #include #include #include

struct DLL_EXPORT Node { friend class boost::serialization::access; unsigned int handle; // handle of current object std::string name; // name of object std::string value; // optional value of object

template <typename Archive> void serialize(Archive& ar, const unsigned int version) { ar & handle; ar & name; ar & value; } };

class DLL_EXPORT Manager { // manager node adds a few extra things used in management of each object struct ManagerNode : public Node { friend class boost::serialization::access; private: template <typename Archive> void serialize(Archive& ar, const unsigned int version) { // serialize base class information ar & boost::serialization::base_object <Node> (*this); } };

NodeMap * _nodes;

// this method compiles fine void save(const std::string & filename) { std::ofstream outFile; outFile.open(filename.c_str(), std::ios::binary); boost::archive::text_oarchive archiveFile(outFile);

const NodeMap * const n = _nodes; archiveFile << *n; }

// fails on compile with STATIC_ASSERTION_FAILURE void load(const std::string & filename) { std::ifstream inFile; inFile.open(filename.c_str(), std::ios::binary); boost::archive::text_iarchive archiveFile(inFile);

_nodes->clear(); archiveFile >> *_nodes; } };

This is on Windows XP using Visual Studio 7.1. The errors start like this:

..\API\inc\boost\archive\detail\iserializer.hpp(557) : error C2027: use of undefined type 'boost::STATIC_ASSERTION_FAILURE<x>' with [ x=false ] ..\API\inc\boost\archive\detail\iserializer.hpp(557) : see reference to class template instantiation 'boost::STATIC_ASSERTION_FAILURE<x>' being compiled with [ x=false ] ..\API\inc\boost\archive\basic_text_iarchive.hpp(64) : see reference to function template instantiation 'void boost::archive::load(Archive &,T &)' being compiled with [ Archive=boost::archive::text_iarchive, T=const unsigned int ] ..\API\inc\boost\archive\text_iarchive.hpp(64) : see reference to function template instantiation 'void boost::archive::basic_text_iarchive<Archive>::load_override<T>(T &,int)' being compiled ** snipped for brevity **

Any help would be greatly appreciated.
