Building boostbook from cvs fails lately.

02 Jun '05

I've been unable to build the boostbook documentation from the cvs sources for some time now. It used to work, but lately I get the errors below. The 'using docbook' paths in ~/user-config.jam are are correct, and were added using 'tools/boostbook/setup_boostbook.sh'. I tried 'rm ../bin.v2/doc/gcc-3.2/debug/catalog.xml' but it didn't help. I rebuilt bjam from todays cvs sources but that didnt help either. % bjam --v2 site-config.jam: No such file or directory Building Boost.Regex with the optional Unicode/ICU support disabled.

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
