Hi All, I'm upgrading some code from 1.34 to 1.35. I seem to have problem with BOOST_CLASS_EXPORT macro... according to the help files: http://www.boost.org/doc/libs/1_35_0/libs/serialization/doc/special.html

...

...

...

If no archive headers are included - no code should be instantiated. This will permit BOOST_CLASS_EXPORT to be a permanent part of the my_class.hpp .<<<<

my code is structured like that, header file for each class, this also has the export macro, one dll contains the archive includes (#include <boost/archive/binary_iarchive.hpp>), other dll's don't contain the archive code, but do need to use my classes... Now, the other dll's can't compile anymore, I get compile errors like: boost\boost\serialization\type_info_implementation.hpp(48) : error C2027: use of undefined type 'boost::serialization::extended_type_info_impl<T>' some info: boost 1.35, visual studio 2005, sp1 Are there any obvious changes to the serialization code that necessitate changes? thanks, Filip Peters ____________________________________________________________________________________ You rock.
