[Serialization] assert fail and unregistered class
by Jari 19 May '11

19 May '11

Hi I get assert fail and "unregistered class - derived class not registered or exported" when serializing. I have many classes being saved already in the code but i ran to a problem saving certain std::list with derived classes. (I also have similar classes and list being serialized before) i think its the same issue as in here: http://boost.2283326.n4.nabble.com/serialization-polymorphic-archives-runti… i have boost version 1.46.1 and visual studio express 2010 heres the call stack: msvcr100d.dll!_wassert(const wchar_t * expr, const wchar_t * filename, unsigned int lineno) Line 325 C gamevc10dbg.exe!boost::archive::detail::basic_serializer_map::find(const boost::serialization::extended_type_info & eti) Line 102 + 0x16 bytes C++ gamevc10dbg.exe!boost::archive::detail::archive_serializer_map<boost::archive::binary_oarchive>::find(const boost::serialization::extended_type_info & eti) Line 67 C++ gamevc10dbg.exe!boost::archive::detail::save_pointer_type<boost::archive::binary_oarchive>::polymorphic::save<BasePlayer>(boost::archive::binary_oarchive & ar, BasePlayer & t) Line 435 + 0xe bytes C++ gamevc10dbg.exe!boost::archive::detail::save_pointer_type<boost::archive::binary_oarchive>::save<BasePlayer>(boost::archive::binary_oarchive & ar, const BasePlayer & t) Line 460 + 0xd bytes C++ gamevc10dbg.exe!boost::archive::detail::save_pointer_type<boost::archive::binary_oarchive>::invoke<BasePlayer *>(boost::archive::binary_oarchive & ar, BasePlayer * const t) Line 473 + 0xd bytes C++ gamevc10dbg.exe!boost::archive::save<boost::archive::binary_oarchive,BasePlayer * const>(boost::archive::binary_oarchive & ar, BasePlayer * const & t) Line 525 + 0xf bytes C++ gamevc10dbg.exe!boost::archive::detail::common_oarchive<boost::archive::binary_oarchive>::save_override<BasePlayer * const>(BasePlayer * const & t, int __formal) Line 69 + 0x15 bytes C++ gamevc10dbg.exe!boost::archive::basic_binary_oarchive<boost::archive::binary_oarchive>::save_override<BasePlayer *>(BasePlayer * const & t, int version) Line 76 C++ gamevc10dbg.exe!boost::archive::binary_oarchive_impl<boost::archive::binary_oarchive,char,std::char_traits<char> >::save_override<BasePlayer *>(BasePlayer * & t, int __formal) Line 52 C++ gamevc10dbg.exe!boost::archive::detail::interface_oarchive<boost::archive::binary_oarchive>::operator<<<BasePlayer *>(BasePlayer * & t) Line 64 C++ gamevc10dbg.exe!saveGame() Line 63 + 0x12 bytes C++ gamevc10dbg.exe!SDL_main(int argc, char * * argv) Line 1517 + 0x5 bytes C++ gamevc10dbg.exe!_main() + 0xfd bytes C gamevc10dbg.exe!_WinMain@16() + 0x1cd bytes C gamevc10dbg.exe!__tmainCRTStartup() Line 547 + 0x2c bytes C gamevc10dbg.exe!WinMainCRTStartup() Line 371 C kernel32.dll!75451194() [Frames below may be incorrect and/or missing, no symbols loaded for kernel32.dll] ntdll.dll!76fbb429() ntdll.dll!76fbb3fc() gamevc10dbg.exe!__CT??_R0?AVbad_cast@std@@@8??0bad_cast@std@@QAE@ABV01@@Z12() + 0xd2ce bytes C++ 003426e2() does any one know whats wrong?

To find a path between two vertices in a tree.
by Nishchal Devnur 19 May '11

19 May '11

Hi, I am looking for a implementation in boost that is efficient in finding a path between two vertices in a given tree. I am right now using the unidrected adjancency list to store the tree. Given a node u and node v I would like to find the path between these two nodes in the tree. Any suggestions is greatly appreciated ! Thanks, Nishchal Devanur

[asio] io_service::run() throws "Transport endpoint is not connected" exception.
by Slav 19 May '11

19 May '11

Hello. I use io_service to asynchronously accept incoming TCP connections and then only asynchronously read/write into accepted incoming connections. Each operation is embraced into try/catch. Call to socket::shutdown(), sometimes, just under Linux (not Windows), fails with "Transport endpoint is not connected" error. That's alright - my server keeps working, but, much more rarely (at least 10 times) an exception with the same name is thrown from io_service::run() which makes my server crash. I embraces all operations with asio (io_service::run(), async_accept(), async_read_some() and async_write()) but it didn't helped - I still catch this exception. It does not happen under Windows. Hot to get rid of it? What's the reason of the exception? Thank you.

Syntax error using signal1 from Boost 1.34.1 on VC6
by tangleman＠secules.net 19 May '11

19 May '11

I am trying to use Boost signals to set up events with VC6. I discovered that build 1.34.1 is the last build to support VC++ 6.0, so that is the version I need to compile with. I noticed from the Signals tutorial on the Boost site that for VC++ 6.0, I have to use the portable syntax. So I declared my signal: #include <boost\signals.hpp> #include <boost\signals\signal1.hpp> #include <vector> typedef boost::signal1<void, std::vector<unsigned char>> signal_t; I am using a vector of unsigned chars as a parameter to the signal handler (event handler), since I am essentially receiving data from an ethernet connection, parsing it, and sending it through the event back to the subscriber. Now the error. using the above code, I get the following error: error C2146: syntax error: missing ',' before identifier 'signal_t' I'm pretty sure I checked and double-checked the syntax several times, comparing it to the example in the signals tutorial. All I can think of is that a vector is not supported as a parameter, yet it was for version 1.46 that I tried earlier. Am I doing anything wrong? Quick responses are much appreciated! Thanks! Chris

[asio] iPad: resolver fails on a "fresh" 3G
by 乔志强 19 May '11

19 May '11

Switch "airplane mode" off and on does not establish a "3G connection". You may active a PDP context before call tcp::resolver::query(connect internet).. > Moreover, it seems that if I try the above query several times, it > succeedes after a while. Maybe iOS active a PDP context for you when you first use the TCP protocol, so You will wait and re-try. You can compare the IP of iPad after switch "airplane mode" off and on and after open the browser. > Message: 3 > Date: Wed, 18 May 2011 16:03:41 +0300 > From: Igor R <boost.lists(a)gmail.com> > To: boost-users(a)lists.boost.org > Subject: [Boost-users] [asio] iPad: resolver fails on a "fresh" 3G > connection > Message-ID: <BANLkTimVfGrDNVXME4VbfPqn-zJsOUOXQg(a)mail.gmail.com> > Content-Type: text/plain; charset=UTF-8 > > Hello, > > I admit this is probably not a pure ASIO question, but perhaps someone > already encountered the following issue (boost 1.46, iOS4.3). > > When trying to resolve a host name just after 3G connection is > established (eg., switch "airplane mode" off and on), I get the > following error: "Host not found (authoritative)". > The query looks like this: > tcp::resolver::query query(tcp::v4(), "my.host.com", "9988"); > > On the other hand, if prior to the above query I open the browser or > some other application that connect to the Internet, then the query > works correctly. > Moreover, it seems that if I try the above query several times, it > succeedes after a while. > > Another interesting point: all the above occurs with 3G connection > only, while with WiFi everything works well. > > What's could be the reason of such a weird behavior? > > Thanks. > >

bidirectional map
by Uthpal Urubail 19 May '11

19 May '11

I am looking for a bidirectional container. Requirement Detail: I need to build a data base where by giving the key i should be getting the list of values. And vice versa [i.e By giving One Value get the list of keys] Eg: For Getting the stacks [SHOULD be in same sequence] Given an element id -11 stacks should be 5, 7 & 4 [Same sequence] For eid id 16 - stacks ids - 5, 2 & 7 And for the other way... Given the stack id 5 eids should be - 11, 16, 7 & 12 [Not necessary to be in same sequence] For stack id 4 - eids- 11 & 12 Please let me know if i could achieve this requirement by using one boost container Any help in this regard would be highly appriocated Regards, UJ
