Hi Jeff, I installed Boost 1.32 on my computer (Windows Server 2003 and Visual Studio .NET 2003). A directory: \boost_1_32_0 was created. In \boost_1_32_0\libs\serialization\vc7ide, I found the projects for building serialization library and test examples. I can build the library (libboost_serialization.lib) and examples, and they run well. All examples are Windows console applications. Then I created an MFC application, linked it with the library. In Document class, I did a test similar to the one presented in demo_xml.cpp and demo_xml.hpp: ... #include "stdafx.h" #include "MFCTests.h" #include "MFCTestsDoc.h" #include <iostream> #include <sstream> #include <string> #include <boost/archive/tmpdir.hpp> #include <boost/archive/xml_oarchive.hpp> #include "demo_xml.hpp" .... void CMFCTestsDoc::OnTestSerialize() { bus_stop *bs0 = new bus_stop_corner( gps_position(34, 135, 52.560f), gps_position(134, 22, 78.30f), "24th Street", "10th Avenue" ); std::string filename(boost::archive::tmpdir()); filename += "/demo.xml"; std::ofstream ofs(filename.c_str()); assert(ofs.good()); boost::archive::xml_oarchive oa(ofs); oa << BOOST_SERIALIZATION_NVP(*bs0); ... } Execution fails in last statement with message: Unhandled exception at 0x77e55dea in MFCTests.exe: Microsoft C++ exception: __non_rtti_object @ 0x0012e800. The build was debug build, application and library were build with runtime library option "Multi-threaded Debug (/MTd)". I tried to use different options such as "Multi-threaded Debug DLL (/MDd)", it failed the same way. In MSDN (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_vst echart/html/boostvc.asp), it discussed Boost for Visual Studio C++. It stated that Boost works well with VC++ 7.1. Of course we know it doesn't work well with previous VC++ such as VC++ 6.0 which I tried and failed badly.

RNG
by Sliwa, Przemyslaw (London) 02 Jun '05

02 Jun '05

All, I have a question which is not related directly to boost. I am writing a multithreaded application and would like to make use of a multiprocessor machine in order to speed up our Monte Carlo simulation engine. We make use of the random number package (random number distributions). My question is: making the random number generator a global variable (object) it is possible to use it in several threads at the same time -> does it mean that the random sequences will be repeated and the entire simulation will be simply a repetition of n non-random sequences? This can be avoided when a lock is acquired on the random number generator and at a given time just one thread can access the rng and the advantage of the multiprocessor machine is lost. Can you advise?

Boost.Tribool: GCC4 and anonymous enums
by Alo Sarv 01 Jun '05

01 Jun '05

GCC4 seems to be rather picky on anonymous enums, and some code seems to break in logic/tribool.hpp with the following error: boost/logic/tribool.hpp: In member function `boost::logic::tribool::operator void (boost::logic::tribool::dummy::*)()() const': boost/boost/logic/tribool.hpp:114: error: `boost::logic::tribool::<anonymous enum>' is/uses anonymous type boost/boost/logic/tribool.hpp:114: error: trying to instantiate `template<class T> struct boost::is_integral' boost/boost/logic/tribool.hpp:114: error: `boost::logic::tribool::<anonymous enum>' is/uses anonymous type boost/boost/logic/tribool.hpp:114: error: trying to instantiate `template<class T> struct boost::is_integral' Same error is repeated at lines 128, 161, and 162 (CVS HEAD). Workaround/patch is obvious (making the enum named), but I haven't managed to create a minimal test-case for the behaviour (the triggering code is rather large and there doesn't seem to be any logic in what actually triggers the error). Any ideas? Alo Sarv

But if I write _2::nr_, it says there is no nr_. Well, the author of _2 can't anticipate all the nested values you might be using. _2 is not magic; it's just a type. // !! untested code !! #include <boost/mpl/size_t.hpp> #include <boost/mpl/plus.hpp> using namespace mpl::placeholders; // A metafunction to get an Element's ::nr_ value template <class Element> struct get_nr_ { // all metadata are types, so wrap it in a type. typedef mpl::size_t<Element::nr_> type; }; typedef mpl::fold< some_list, mpl::size_t<0> , mpl::plus< _1 , get_nr_<_2> > >::type sum; // sum::value contains the value you're interested in. > I fugured it wants a type.

I try to use mpl::accumulate. Yes, that's a synonym for fold if you have a version of the MPL that includes accumulate. > Finally I guess I will have to use transform in some way, because I > need a list which has an mpl::pair (if there is one) http://www.boost.org/libs/mpl/doc/refmanual/pair.html > of the original type and the sum of all nr_'s before it. Seems like it's still a job for fold. In this case I'd use mpl::vector because lists can only be push_front-ed and you probably don't want to end up with your elements in "reverse" order. typedef mpl::fold< some_list , mpl::pair< // initial state mpl::vector0 // initial sequence , mpl::size_t<0> // initial sum > , mpl::pair< // the state at each step is a pair containing mpl::push_front< // added to the front of... mpl::first<_1> // the sequence from the previous step , mpl::pair< // a new element, a pair containing _2 // the original type , mpl::plus< // and the sum of mpl::second<_1> // the sum from previous step , get_nr_<_2> // the ::nr_ of the original type > > > , mpl::plus< // and the sum of mpl::second<_1> // the sum from previous step , get_nr_<_2> // the ::nr_ of the original type > > >::type pair_seq_sum; typedef pair_seq_sum::first new_sequence; So this is pretty verbose using lambdas because the sum is repeated, among other things. You might do better to build a custom metafunction that gets you the new state: template <class PrevState, class Element> struct next_state { typedef typename PrevState::first prev_sequence; typedef typename PrevState::second prev_sum; typedef mpl::size_t<(prev_sum::value + Element::nr_)> new_sum; typedef typename mpl::push_back< prev_sequence , mpl::pair<Element, new_sum> >::type new_sequence; typedef mpl::pair<new_sequence, new_sum> type; }; typedef mpl::fold< some_list, mpl::fold<_,_> >::type pair_seq_sum; typedef pair_seq_sum::first new_sequence; > Can you help me? I have > something like this: > > struct T1 { > enum x { > label1, > label2, > nr_; > }; > }; > > // Same for T2, possibly less or more labels etc. > > And I would like to end up with a type which looks like this: > > struct something { > int get(T1::x n) { > return arr_[n]; > } > int get(T2::x n) { > return arr_[n+2]; Where does n+2 come from? > } > // etc. > private: > int arr_[sum_of_all_nr_]; > }; ?? that doesn't look anything like what you just described. Sheesh. The above is still a job for fold. I suggest you start with a base type: template <class Derived> struct base { enum { sum = 0 }; void get(); // never used. }; then build layers: template <class Base, class T, class MostDerived> struct layer : mpl::apply<Base, MostDerived>::type { typedef typename mpl::apply<Base, MostDerived>::type super; enum { sum = T::nr_ + super::sum }; using Base::get; int get(T::x n) { return static_cast<MostDerived*>(this)->arr_[n]; } }; template <class Folded> struct outer : Folded { int arr_[Folded::sum]; }; Well, the above "solution" won't work and I don't have time to write something that does for you right now. It would take maybe another 15 minutes and I've already spent 30 on this email. I guess you'll probably do best to make 2 passes over the sequence: one to compute the sums and the other to build the result type. Good luck! -- Dave Abrahams Boost Consulting www.boost-consulting.com
