Hi, The following test generates an error : class Position { const float & GetX() const {...} float & GetX() {...} }; Position myPos; bind( &Position::GetX, ref(myPos) ) // <- does not compile How can I avoid these ? : (with MSVC 7.1) test.cpp(39) : error C2780: 'const boost::lambda::lambda_functor<boost::lambda::lambda_functor_base<boost:: lambda::action<10,boost::lambda::function_action<10,Result>>,detail::bin d_tuple_mapper<const Arg1,const Arg2,const Arg3,const Arg4,const Arg5,const Arg6,const Arg7,const Arg8,const Arg9,const Arg10>::type>> boost::lambda::bind(const Arg1 &,const Arg2 &,const Arg3 &,const Arg4 &,const Arg5 &,const Arg6 &,const Arg7 &,const Arg8 &,const Arg9 &,const Arg10 &)' : expects 10 arguments -

I'm trying to build Boost on OpenVMS I64 8.2 and it fails in building jam. Has anyone succeeded in building on 8.2? If so, can you provide the cc and linker options you used? Thanks. P

[serialization] reference to a vector of shared pointers of objects with non-default constructible templated class
by codeur＠altern.org 29 Nov '05

29 Nov '05

Hello, I have a non-default templated class (let's call it Klass), serialized throw a pointer, so I redefined save_construct_data and load_construct_data for the type Klass<double>. One of the member of my class has the following type: typedef boost::shared_ptr< Point3d<T> >PointPtr; vector< PointPtr >& stuff; Point3d is another templated class. T could be for instance, double. Point3d is track_selectivly, Klass is track_selectivly and serialized by another class with a pointer. In save_construct_data when I do : ar << t->stuff; I've got the following problem : boost-1_33/boost/archive/detail/oserializer.hpp:566: error: incomplete type `boost::STATIC_ASSERTION_FAILURE<false>' does not have member `value' Perhaps I didn't place the good track attribute. Does someone have an idea ? Thanks in advance!

Boost.python serialization
by Drumheller, Michael 29 Nov '05

29 Nov '05

I'm just getting started with trying to serialize some Python and C++ objects that are glued together with Boost.Python. Would it be fair to say that this link <<http://mail.python.org/pipermail/c++-sig/2004-September/008044.html>> represents the "standard" approach to this? Thanks, MD

How to find type boost::variant is holding?
by Merrill Cornish 28 Nov '05

28 Nov '05

If I have a boost::variant variable holding either of two types, is there a simple test to determine which type it is currently holding? Yes, I know that the object-oriented way to to avoid testing for types at runtime, but a simple if-test would work very well in the code. I've seen the static_visitor example, and that would work, but it hides the type determination and type-specific actions inside another class (or at least other functions). Yes, that would work logically, but the code needing to make this determination would be much clearer is written simply as a if-the-else based on the current type of the variant variable. Merrill

[counting_iterator] restriction/bug in distance_to()
by Martin Weigel 28 Nov '05

28 Nov '05

Hi, counting_iterator.hpp defines the distance_to() member function as follows (from CVS HEAD), template <class OtherIncrementable> difference_type distance_to(counting_iterator<OtherIncrementable> const& y) const { ... Since the argument counting_iterator<OtherIncrementable> uses the default values for CategoryOrTraversal and Difference, this distance_to() template does not apply for counting_iterator's with other than the default values for CategoryOrTraversal and Difference. In particular, for a counting_iterator with non-default CategoryOrTraversal or Difference, the necessary function typedef counting_iterator<Incrementable, CategoryOrTraversal, Distance> it_type; it_type::distance_to(it_type const&) cannot be instantiated from the above template, resulting in a compile-time error. Best, Martin

[serialization] pointer derived from an abstract templated class
by codeur＠altern.org 28 Nov '05

28 Nov '05

Hello, I know the question has already been asked (http://groups.google.com/group/boost-list/browse_thread/thread/9e1bcbd7c4f7…) but without answers. So I retry.. Is it possible to serialize an object that inherits from a templated abstract class ? For instance : template<typename T> class base { }; template<typename T> class Impl : public base<T> { }; int main(/* ... */) { base *b = new Impl(type); // how can we serialize b ? } Thanks for your help.
