[Serialization] Pointer to const
by Loïc Joly 12 Sep '05

12 Sep '05

Hello everybody, There a still many stuff I do not understand how to do with boost::serialization. One of them is the following : Let's say I have the following classes : struct B { int i; template<class Archive> void serialize(Archive & ar, const unsigned int version) { ar & i;} }; struct A { B const *pc; template<class Archive> void serialize(Archive & ar, const unsigned int version) { ar & pc; } }; When I try to serialize a A, I get the following error (MSVC8 beta 2): c:\boost\include\boost-1_33\boost\archive\detail\iserializer.hpp(474) : error C2440: 'reinterpret_cast' : cannot convert from 'const B **__w64 ' to 'void **' Conversion loses qualifiers c:\boost\include\boost-1_33\boost\archive\detail\iserializer.hpp(471) : while compiling class template member function 'void boost::archive::detail::load_pointer_type<Archive,Tptr>::invoke(Archive &,Tptr &)' with [ Archive=boost::archive::text_iarchive, Tptr=const B * ] Of course, if I replace B const *pc by B *pc, then the code works correctly.What can I do to serialize pointers to const data ? Regards, -- Loïc

Problem with Serialization and Building with Managed Extensions
by Jared McIntyre 12 Sep '05

12 Sep '05

I am trying to use boost::serialization in a managed code (CLR) project in Visual Studio. The area that serialization is being used, and all the objects that are being serialized, and standard C++. There are no managed objects related to the serialization process. In fact, I have a test app that reproduces the problem that can be built and run without managed extensions on. But, if I turn building with managed extensions on, several parts of the of the serialization templates turn up missing at link time. I get several errors like the following: LINK : error LNK2020: unresolved token (0A00013F) std._Uninitialized_fill_n<class boost::variant<class TestClass,int,float,double,class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >,struct boost::detail::variant::void_,struct boost::detail::variant::void_,struct boost::detail::variant::void_,struct boost::detail::variant::void_,struct boost::detail::variant::void_,struct boost::detail::variant::void_,struct boost::detail::variant::void_,struct boost::detail::variant::void_,struct boost::detail::variant::void_,struct boos LINK : error LNK2020: unresolved token (0A000158) std._Uninit_fill_n<class boost::variant<class TestClass,int,float,double,class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >,struct boost::detail::variant::void_,struct boost::detail::variant::void_,struct boost::detail::variant::void_,struct boost::detail::variant::void_,struct boost::detail::variant::void_,struct boost::detail::variant::void_,struct boost::detail::variant::void_,struct boost::detail::variant::void_,struct boost::detail::variant::void_,struct boost::deta Also, during build, the compiler doesn't like the use of __fastcall in several areas of the code. For example: ..\..\..\..\boost\boost_1_33_0\boost\type_traits\detail\is_mem_fun_pointer_tester.hpp(2443) : warning C4561: '__fastcall' incompatible with the '/clr' option: converting to '__stdcall' I don't know if these are related. I'm using VS 7.1. Does anyone have any thoughts on what I should look at from here? Thanks, Jared McIntyre

Massive Spamming of the boost Wiki
by Peter Schmitteckert (boost) 12 Sep '05

12 Sep '05

Dear All, sadly, the Boost wiki is currently spammed with a big amount of spam, see e.g. <http://www.crystalclearsoftware.com/cgi-bin/boost_wiki/wiki.pl?RecentChanges> Since the IP adress is logged, I'd like to ask wether there's a possibility for action. I'm reporting this, because if the spamming continues on this level the wiki will be rendered useless soon. Best regards, Peter

Should the community come up with a list of alternative implementations that could be evaluated and used as a starting point? Or do we need to go back a step further and decide what types of mutexes or primitives are actually desired?

Any interest in a chart library
by Schrom, Brian T 12 Sep '05

12 Sep '05

I've been working on a charting library for a few weeks and am wondering whether their would be any interest in having a boost one. I'm not even sure that it makes sense for boost, as it seems a higher level library than most of libraries and also unrelated to other libraries. There would be many things to work out, like no graphics in Boost (that I'm aware of), my not being an expert C++ person, etc, so I'm just trying to get a feel whether it is worth pursuing more here or not, or if there would be another forum that would be better. By charting library, I mean something that you can give data to and that it plots it in a view port, with axis, labels, title etc like you would get with Excel charts, Gnu Plot, Pro-Essentials, etc Thanks, Brian
