In another painfully hunt to fix the problems with the seriazation lib issues in CW8... I tracked the problem down to another instance of: static_cast<const&>(x) where x is a template with template ctors. The problem was in iterator_facade, and not directly in the serialization lib which made it even harder to find :-( Anyway, I applied this change (figured since this is a known problem by now with an easy portable solution it would not be a problem)... =================================================================== RCS file: /cvsroot/boost/boost/boost/iterator/iterator_facade.hpp,v retrieving revision 1.26 retrieving revision 1.27 diff -u -r1.26 -r1.27 --- iterator_facade.hpp 31 Jul 2004 18:10:00 -0000 1.26 +++ iterator_facade.hpp 31 Jul 2004 22:56:49 -0000 1.27 @@ -814,8 +814,8 @@ is_interoperable< Derived1, Derived2 >::value \ )); \ return_prefix iterator_core_access::base_op( \ - static_cast<Derived1 const&>(lhs) \ - , static_cast<Derived2 const&>(rhs) \ + *static_cast<Derived1 const*>(&lhs) \ + , *static_cast<Derived2 const*>(&rhs) \ , BOOST_ITERATOR_CONVERTIBLE(Derived2,Derived1) \ ); \ } =================================================================== After that the serialization lib builds, and tests run. Of course not all tests pass ;-) VC7.1 and Mingw behave as before also. PS. There was one other minor change to the libs/serialization/test/Jamfile to account for locale requirement. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com - 102708583/icq
