Hi the code below compiles and runs, but does not do what I want. how can I get the code below to print out: "I am child 1sub thread called." thanks ****************************************************************** #include <boost/thread/thread.hpp> #include <string> #include <iostream> using namespace std; class Child { string c; public: Child(string x):c(x){ } void operator()(){ cout << c << " sub thread called." << endl; } }; class Parent { string p; public: Parent(string x):p(x){} void operator()(){ cout << p << "thread called." << endl; Child c1("I am child 1"); boost::thread c1t(c1); } }; int main(){ Parent p1("I am parent 1: "); boost::thread p1t(p1); } --------------------------------- Everyone is raving about the all-new Yahoo!

bind a boost::fusion::at_key
by Pierre viallet 24 Nov '06

24 Nov '06

Hi, I'm trying to bind boost::fusion::at_key, but i do not understand why the following piece of code do not compile : struct tag { class a; class b; class c; }; typedef boost::fusion::map< bf::pair<tag::a, size_t> , bf::pair<tag::b, size_t> , bf::pair<tag::c, size_t> > TMyFusionMap; TMyFusionMap aFusionMap(7,8,9); std::cout << boost::fusion::at_key<tag::b>(aFusionMap) << std::endl; //work std::cout << boost::bind(&boost::fusion::at_key<tag::b>, _1)(aFusionMap) << std::endl; //do not compile on msvc 8.0 std::cout << boost::bind<size_t &>(&boost::fusion::at_key<tag::b>, _1)(aFusionMap) << std::endl; //do not compile on msvc 8.0 any idear ? ___________________________________________________________________________ Découvrez une nouvelle façon d'obtenir des réponses à toutes vos questions !

[MultiIndex] VC8: spurious compiler error
by Markus Werle 24 Nov '06

24 Nov '06

Hi! I am out of ideas here, but somebody probably fell into that trap before. Since the error message points to unrelated code, I hope to get some idea via Boost: boost_1_33_1\boost/multi_index/ordered_index.hpp(445) : error C2143: syntax error : missing ',' before '.' Since I had VC8 messing things up before I bet it is the #include order again, but I could not find the offending header yet. Markus

Iterate over all matching items with hashed_non_unique
by Joseph Turian 24 Nov '06

24 Nov '06

I have a boost_multi_index with a hashed_non_unique key. I understand that if I do a .find() for a particular key, I can get a single entry with that key. However, I want to iterate over *ALL* the entries with this particular key, since there may be several. How do I do this? I can't figure out which is the correct end iterator. e.g. something along the following lines [haven't tried to compile] typedef FirstName string; typedef multi_index_container< Employee, indexed_by< hashed_non_unique<member<tag<FirstName>, Employee,FirstName,&Employee::first_name> > > > employee_set; typedef employee_set::index<FirstName>::type example_set_by_movie; boost::multi_index::get<FirstName>(m_employees).find("john"); -- http://www.cs.nyu.edu/~turian/

[serialization] Difficulties with shared_ptr and export.hpp
by Deane Yang 24 Nov '06

24 Nov '06

First, I am trying to figure out how to use BOOST_CLASS_EXPORT. I am trying to do it using the following advice from the documentation: "As noted in the comments, this would work. But #include <.../export.hpp> can't be used without conflicting with other modules which use #include <.../*archive.hpp>. In this case we can move the export to an implementation file: // A.cpp #include "A.hpp" ... // export.hpp header should be last; #include <boost/serialization/export.hpp> ... BOOST_CLASS_EXPORT(A) ..." In fact, my implementation file contains *only* BOOST_CLASS_EXPORT statements. Code like this seems to compile only if I also include archive headers like: #include <boost/archive/xml_oarchive.hpp> #include <boost/archive/xml_iarchive.hpp> If these directives are omitted, then my code does not compile. Is this correct? (I didn't see anything about this in the documentation) But now if a class that is being exported contains a boost::shared_ptr<..> member (so I have to #include boost/serialization/shared_ptr.hpp), then I get the following compilation errors (in MSVC8.0express): ..\..\..\vendor\boost\boost/serialization/shared_ptr.hpp(134) : error C2039: 'reset' : is not a member of 'boost::archive::naked_xml_iarchive' ..\..\..\vendor\boost\boost/archive/xml_iarchive.hpp(91) : see declaration of 'boost::archive::naked_xml_iarchive' ..\..\..\vendor\boost\boost/serialization/split_free.hpp(58) : see reference to function template instantiation 'void boost::serialization::load<Archive,AndrewKalotayAssociates::Basic::Output::ValuationReport>(Archive &,boost::shared_ptr<T> &,const unsigned int)' being compiled Can someone tell from this what I'm doing wrong?

[mpl::map] pregeneration of long types map (150 types)
by Ovanes Markarian 23 Nov '06

23 Nov '06

Hello Alexey, using the C++ preprocessor macro to generate map of 150 types works fine and code which uses the new mapN type compiles and runs fine as well. Just as you described it in the post: http://lists.boost.org/boost-users/2006/11/23321.php We have successfully tested it with 115 elements. Then we tried to switch to the second approach with pregenerated types. The problem we face is that the python script generates empty headers. To avoid all errors we just copied <boost_root>\boost\mpl\map\map50.hpp to <boost_root>\boost\mpl\map\map60.hpp and changed the file accordingly.

Doing the same thing by passing map50.cpp works just fine and pregenerates new files. Is there smth, that I miss? With Kind Regards, Ovanes Markarian

[serialization] Trouble serializing a bitfield
by Ken Roser 23 Nov '06

23 Nov '06

Following is a very short program to test serialization along with the g++ output when compiling it. My problem arises when I try to write a serialization function for a bitfield. As the compiler output shows, the bitfield is the cause of this problem. How should one serialize a bitfield? Have I made some mistake in this code? I can get seriailziation to work if I instead use a save() and load() function that copies each bit to an int before archiving but I'm unsure if this is the best way. #include <stdlib.h> #include <string> #include <iostream> #include <sstream> #include <boost/archive/archive_exception.hpp> #include <boost/archive/binary_iarchive.hpp> #include <boost/archive/binary_oarchive.hpp> #include <boost/archive/text_iarchive.hpp> #include <boost/archive/text_oarchive.hpp> #include <boost/serialization/export.hpp> #include <boost/serialization/serialization.hpp> #include <boost/serialization/list.hpp> class Event { friend class boost::serialization::access; template<class Archive> void serialize(Archive &ar, const int version) { ar & bits; ar & field1; }; public: struct s { friend class boost::serialization::access; template<class Archive> void serialize(Archive &ar, const int version) { ar & spare1; }; int spare1 : 1; } bits; int field1; }; main(int argc, char **argv) { Event *evt = new Event; evt->field1 = 0x1234; std::stringstream ofs; boost::archive::binary_oarchive oa(ofs); oa & *evt; // serialize the event } serial2.cpp: In member function 'void Event::s::serialize(Archive&, int) [with Archive = boost::archive::binary_oarchive]': boost/serialization/access.hpp:109: instantiated from 'static void boost::serialization::access::serialize(Archive&, T&, unsigned int) [with Archive = boost::archive::binary_oarchive, T = Event::s]' boost/serialization/serialization.hpp:81: instantiated from 'void boost::serialization::serialize(Archive&, T&, unsigned int) [with Archive = boost::archive::binary_oarchive, T = Event::s]' boost/serialization/serialization.hpp:140: instantiated from 'void boost::serialization::serialize_adl(Archive&, T&, unsigned int) [with Archive = boost::archive::binary_oarchive, T = Event::s]' boost/archive/detail/oserializer.hpp:147: instantiated from 'void boost::archive::detail::oserializer<Archive, T>::save_object_data(boost::archive::detail::basic_oarchive&, const void*) const [with Archive = boost::archive::binary_oarchive, T = Event::s]' serial2.cpp:43: instantiated from here serial2.cpp:29: error: cannot bind bitfield '((Event::s*)this)->Event::s::spare1' to 'int&'

program_options inconsistent dll linkage

Ah, OK. Too many TLA's... As an aside, I use the Eclipse IDE, with the CDT, and that has a good enough front end for GDB to debug most stuff.
