[serialization] Polymorphic archives in 1.38
by Richard Hazlewood 29 Jul '09

29 Jul '09

I've been using serialization with polymorphic archives from boost 1.38, but I had to apply the patch given by Vladimir Prus (http://lists.boost.org/boost- users/2009/03/45658.php) to get it linking (with MSVC71). E.g.: #include <boost/archive/polymorphic_text_oarchive.hpp> #include <boost/archive/polymorphic_text_iarchive.hpp> #if BOOST_VERSION <= 103800 #include <boost/archive/impl/archive_pointer_oserializer.ipp> #include <boost/archive/impl/archive_pointer_iserializer.ipp> namespace boost { namespace archive { template class detail::archive_pointer_iserializer<polymorphic_text_oarchive>; template class detail::archive_pointer_iserializer<polymorphic_text_iarchive>; }} #endif #include <boost/serialization/export.hpp> #include <sstream> struct A { template <typename A> void serialize(A &, const unsigned) {} }; BOOST_CLASS_EXPORT(A); void test_ser() { A a; std::ostringstream ostr; boost::archive::polymorphic_text_oarchive arch(ostr); arch & a; } Can anyone tell me if this has been addressed in 1.39? I.e. does the above compile and link with 1.39 (on MSVC71)? TIA. Chard.

[boost] upgrade boost 1.33 up to 1.39 -> MCF assertion
by Andrey Torba 29 Jul '09

Hello everybody! When i upgrade boost form 1.33.1 up to 1.39 I get the following assertion failed error message: Debug Assertion Failed! File: F:\dd\vctools\vc7libs\ship\atlmfc\src\mfc\dllinit.cpp Line: 587 ================== void AFXAPI AfxCoreInitModule() { ASSERT(AfxGetModuleState() != AfxGetAppModuleState()); All run ok when i rollback boost. There are breaking changes in boost.Thread http://www.boost.org/doc/libs/1_39_0/doc/html/thread/changes.html since 1.33 Interface of scoped_lock has been changed and boost::mutex now is boost::recursive_mutex. Am i right? Did anybody experiance this problem? Any help is appreciated. -- Regards, Andrey

Is it possible to compile boost::serialization with vc7.1+stlport5.1.5?
by Li Ning 29 Jul '09

error 2039 & 2873 at boost\archive\codecvt_null.hpp(30). A problem of codecvt namespace. It seems stlport hides codecvt's namespace out of gobal.

I wonder how can you identify the bug in the source files as I was totally no idea when I saw the error message.

strange linker error with boost::function
by Noah Roberts 28 Jul '09

28 Jul '09

Can anyone think why I would get an unresolved symbol on this monstrosity from the liker: public: __thiscall boost::function< class std::auto_ptr<struct esi::command::command> __cdecl(class std::vector< struct esi::draw::primitives::point_impl<double> ,class std::allocator<struct esi::draw::primitives::point_impl<double> > > const & ) > ::function < class std::auto_ptr<struct esi::command::command> __cdecl(class std::vector< struct esi::draw::primitives::point_impl<double> ,class std::allocator<struct esi::draw::primitives::point_impl<double> > > const & ) > < class std::auto_ptr<struct esi::command::command> (__cdecl*)(class std::vector< struct esi::draw::primitives::point_impl<double> ,class std::allocator<struct esi::draw::primitives::point_impl<double> > > const & ) > (class std::auto_ptr<struct esi::command::command> (__cdecl*)(class std::vector< struct esi::draw::primitives::point_impl<double> ,class std::allocator<struct esi::draw::primitives::point_impl<double> > > const & ) ,int ) I tried to clean it up a bit. Looks to me like there's no instantiation of the appropriate constructor to the function template. I tried to recreate the problem in a simple sample but can't seem to do it. Hoping that I'm falling foul of a common issue that someone might be able to just give me pointers toward fixing.

null instruction ptr bugcheck in regexp
by Heidi Zhou 28 Jul '09

28 Jul '09

Hello! I am using boost regexp to do string/expression match. I got several dump files that have the same call stack when the crash happends. What my code does is copying user buffer (containing string to be mached) to an internal allocated buffer and then call boost regexp functions. From the following result of windbg's "analyze", can you tell what cause the null intrstrucation ptr? I check the memory that contains the string to macht and didn't find any wrong. Also, btw, where can I find boost pdb? Thank you. ==================================================== FAULTING_IP: +0 00000000 ?? ???

[function_traits] How to detect function arity for functors with member template?
by jesseperla 28 Jul '09

28 Jul '09

I am interested in tag dispatching in a generic function depending on whether the passed in argument is arity 1 or 2. My problem is that I want to have a generic expectation operator that is passed in a function to take the expectation over, and a distribution for the integration. The expectation needs to support both real and mixed-integer measures and functions. Consider the following functions it should work with: struct my_real_functor { template<std::size_t N> double operator()(ublas::bounded_vector<double,N>& x) {...} }; template<std::size_t N> double my_real_function(ublas::bounded_vector<double,N>& x) {...} struct my_mixed_functor { template<std::size_t RealN, std::size_t IntN> double operator()(ublas::bounded_vector<double,RealN>& real_x, ublas::bounded_vector<int,RealN>& int_x) {...} }; .... naturally, part of the problem is that the functor could have both specializations, so I recognize this might be tricky. If both are on a functor, then I can default to one of the implementations(probably the unary) for the matching. --------------------------------------------------- For the operator itself, the signature would be something like. <class F, class Distribution> double expectation(F f, const Distribution& dist) { .....// tag dispatch depending on F arity, or something similar. } ..... or even better: <class F, class Distribution> double expectation(mpl::enable_if<has_unary,F>::type f, const Distribution& dist) { .....//unary implementation } <class F, class Distribution> double expectation(mpl::enable_if<has_binary,F>::type f, const Distribution& dist) { .....// binary implementation. } .... or even better if I could fully match the signatures of the passed in F for conformance. ------------------------------------------------------ I looked at boost function_traits but it doesn't work with member functors.... http://www.boost.org/doc/libs/1_39_0/libs/type_traits/doc/html/boost_typetr… Any ideas on how best to implement this? Thanks as always, Jesse

Re: [Boost-users] null instruction ptr bugcheck in regexp

I havn't received replies on this, and wonder where is the correct place that I should post this kind question. I got full stack using VS 2005. It tells that register EBP is corrupted in the function boost::re_detail::abstract_protected_call::execute. Before this function, the value of EBP value is correct. Is there any similar problem that has been known already? Thank you.
