Hi Robert
I ask again for any help on this point since I am now stack with this error.
Join my previous mail and your answer about this integral_c_tag
---------------------------------------------------------------------- Hi Robert
I got this error from error C2039: 'integral_c_tag' : n'est pas membre de 'boost::mpl'
Here the beginning of level.hpp I got: ---------------------------------------------------------------------------- ------ #include <boost/mpl/int.hpp> #include <boost/mpl/integral_c.hpp> #include <boost/serialization/level_enum.hpp> #include <boost/serialization/traits.hpp> namespace boost { namespace serialization { // default serialization implementation level template<class T> struct implementation_level { template<class U> struct traits_class_level { typedef BOOST_DEDUCED_TYPENAME U::level type; }; typedef mpl::integral_c_tag tag; // <== problem here // #if BOOST_WORKAROUND(__IBMCPP__, BOOST_TESTED_AT(600)) // typedef ---------------------------------------------------------------------------- --------
From what I check of the latest HEAD release from CVS, it should be integral_c instead of integral_c_tag??
Regards

Hmmm - I looked into this and I don't think its an error. level and tracking are mpl "integer types" with special "sauce" and I think that this is what ineger_c_tag is meant to be used for. Also I note that none of our tests flag this as an error. I'm not all together sure about this so anyone is free to help out here.
Well, Robert, the docs admittedly never say where you should find integral_c_tag (it's only mentioned in http://www.boost.org/libs/mpl/doc/tutorial/numeric-metafunction.html AFAICT), but it seems pretty obvious to me that you shouldn't expect to get integral_c_tag just because you #included integral_c.hpp. Maybe #include <boost/mpl/integral_c_tag.hpp> would help? Francis, if you add that to the beginning of level.hpp, does it fix the problem? -- Dave Abrahams Boost Consulting www.boost-consulting.com
