That is excellent! We indeed use version 1.33.0 now, so I'll download the newest version and follow you advice. Thank you very much! Mikhail "Robert Ramey" <ramey@rrsd.com> wrote in message news:dncbas$ehq$1@sea.gmane.org...
I'm not sure which version of boost you're using. 1.33.0 did have restriction regarding header order which has been removed except for a couple of special cases.
The following code compiles without error with 1.33.1
#include <boost/serialization/version.hpp> #include <boost/serialization/export.hpp> namespace boost { namespace serialization { class access; } } class A { }; BOOST_CLASS_VERSION(A, 1) BOOST_CLASS_EXPORT(A)
Implementation of BOOST_CLASS_EXPORT is such that this must follow any boost/archive/... headers. So in your application program I would expect to see the following:
#include <boost/archive/polymorphic_archive.hpp> // and/or anyother archives
#include "A.h" // any other imported classes
... ar & a ...
And I would expect everything to work as expected. If A.h is included on other code which does not invoke serialization, compile time should be unaffected by inclusion of the serialization macros.
