Have you tried whether serialization works for you if you just serialize the concrete class ConstCellValueStrategy? Matthias On 28 Jun 2008, at 14:08, michalurbanski wrote:
Hi,
I get an error "error: no matching function for call to ‘load_wrapper(boost::archive::xml_iarchive&, const float&, boost::serialization::is_wrapper<float>" for the code of classes (1) and (2). The compiler output is in (3).
The error comes from line "ar & BOOST_SERIALIZATION_NVP(constValue);"
If I comment the line "BOOST_CLASS_EXPORT(ConstCellValueStrategy)" the code compiles fine, but while running I get a "terminate called after throwing an instance of 'boost::archive::archive_exception' what(): unregistered class".
Any ideas what do I do wrong?
Regards, MU.
