date_time: convert to and from a timeval
by Thomas Lemaire 06 Jan '06

06 Jan '06

Dear list, I would like to convert ptime and time_duration to and from the standard timeval type. So that I can use all the operators available for ptime and time_duration I found that this topic has already been discussed here: http://lists.boost.org/Archives/boost/2003/06/49197.php The conclusion was: "" Ok will do. I'll add some protections or rounding for when durations support higher than microsecond resolution. I'll let you know when this gets added. Thx, Jeff "" This … [View More]

[serialization] assert when serializing polymorphic type to XML (Visual Studio 8)
by Terence Wilson 06 Jan '06

06 Jan '06

I have condensed a short example which is appended to this message. The code tries to write then read a polymorphic class via a base pointer. The assertion I am seeing is assert(NULL != bpos_ptr); in oserializer.hpp. The documentation indicates that the problem is likely a lack of registration of the class, however, I have done this. Interestingly the code only fails for XML archive type. // BoostPolymorphicSerialize.cpp : Defines the entry point for the console application. // #include <… [View More]stdio.h> #include <tchar.h> #include <iomanip> #include <iostream> #include <fstream> #include <string> #include <boost/archive/tmpdir.hpp> #include <boost/archive/text_iarchive.hpp> #include <boost/archive/text_oarchive.hpp> #include <boost/serialization/base_object.hpp> #include <boost/serialization/utility.hpp> #include <boost/serialization/list.hpp> #include <boost/serialization/export.hpp> #include <boost/shared_ptr.hpp> #include <boost/shared_array.hpp> #include <boost/serialization/shared_ptr.hpp> #include "boost/archive/xml_iarchive.hpp" #include "boost/archive/xml_oarchive.hpp" class CMyBaseClass { public: CMyBaseClass(void):m_BaseValue(0){} public: virtual ~CMyBaseClass(void){} int m_BaseValue; friend class boost::serialization::access; template<class Archive> void serialize(Archive & ar, const unsigned int /* file_version */) { ar & BOOST_SERIALIZATION_NVP(m_BaseValue); } }; class CMyDerivedClass : public CMyBaseClass { public: CMyDerivedClass(void):m_DerivedValue(1){} public: ~CMyDerivedClass(void){} int m_DerivedValue; friend class boost::serialization::access; template<class Archive> void serialize(Archive & ar, const unsigned int /* file_version */) { BOOST_SERIALIZATION_BASE_OBJECT_NVP(CMyBaseClass); ar & BOOST_SERIALIZATION_NVP(m_DerivedValue); } }; BOOST_CLASS_EXPORT_GUID(CMyBaseClass, "CMyBaseClass") BOOST_CLASS_EXPORT_GUID(CMyDerivedClass, "CMyDerivedClass") int _tmain(int argc, _TCHAR* argv[]) { const CMyBaseClass* const pMyBaseClass=new CMyDerivedClass(); const std::string fileName("c:\\docs\\BoostSerializeTest.xml"); CMyBaseClass* pMyBaseClass2=0; try { { std::ofstream ofs(fileName.c_str()); assert(ofs.good()); boost::archive::xml_oarchive oa(ofs); //boost::archive::text_oarchive oa(ofs); oa << BOOST_SERIALIZATION_NVP(pMyBaseClass); } { std::ifstream ifs(fileName.c_str()); assert(ifs.good()); boost::archive::xml_iarchive ia(ifs); //boost::archive::text_iarchive ia(ifs); ia >> BOOST_SERIALIZATION_NVP(pMyBaseClass2); } } catch(std::exception& e) { std::cout << e.what() << std::endl; } delete pMyBaseClass; delete pMyBaseClass2; return 0; } [View Less]

Re: [Boost-users] [Boost.Program_options] Is there a way to havealloptions specifiedwith a single dash instead of double?
by Guy Peled 06 Jan '06

06 Jan '06

Okay, I finally found out the missing part. In case someone else is looking for the same info, here's my finding: There's additional flags that can be used to control this behavior, specifically the command_line_style::style_t::allow_long_disguise is the one that will make single dash options work exactly like double-dash. Here's an example : namespace po = boost::program_options; po::command_line_style::style_t style = po::command_line_style::style_t( po::command_line_style::… [View More]unix_style | po::command_line_style::case_insensitive | po::command_line_style::allow_long_disguise ); string inputFilename; string statelessTeslaMethodsFilename; string strConfigFile; po::options_description desc2; desc2.add_options() ( "config-file", po::value< std::string >( & strConfigFile )->default_value( "jaja" ) ); po::variables_map vm2; po::store(po::parse_command_line(argc, argv, desc2, style ), vm2); po::notify(vm2); Enjoy, Guy. ________________________________ From: Guy Peled Sent: Thursday, January 05, 2006 9:15 AM To: 'boost-users(a)lists.boost.org' Subject: RE: [Boost-users] [Boost.Program_options] Is there a way to havealloptions specifiedwith a single dash instead of double?

Is boost compilation supported with VC 7.0 (Visual Studio 2002)?
by Allen Zhao 05 Jan '06

05 Jan '06

Hi, All, I am having troubles to compile libtorrent 0.9.1 which depends on boost 1.33+. From the error messages, boost does not work very well with Visual Studio 2002. What puzzles me more is that if I just build the boost alone by invoking bjam in the boost directory, I still can not build the whole library because of the spirit section; but all the errors as reported below does not appear. This seems to indicate some compiler options issues. Is there any successful story that you can … [View More]share with me with regards to VC 7.0 compilation? Any pointers are welcome.

Hi, I'm using vc.net and when linking with mfc71d.lib memory leaks are reported for this code: void doNothing() {} int main() { boost::thread* thrd = new boost::thread( &doNothing ); thrd->join(); delete thrd; return 0; } Does it leak on other platforms too? When I build the thread on the stack instead, everything works fine. Thx for help, Boris

Hi, the attached source code is copied from boost_1_33_0/libs/graph/example/adjacency_list.cpp, I only changed the edge container to be slist, and include <slist.h> I compiled it on linux with AMD opteron 844 processor. gcc2.95.3 works fine, but gcc3.3 doesn't compile. I think the reason is slist is not in std namespace in gcc3.3, and adjacency_list.hpp doesn't handle this correctly for slist. > grep BOOST_STD_EXTENSION_NAMESPACE adjacency_list.hpp adjacency_list.hpp: … [View More]typedef BOOST_STD_EXTENSION_NAMESPACE::slist<ValueType> type; adjacency_list.hpp: typedef BOOST_STD_EXTENSION_NAMESPACE::hash_set<ValueType> type; adjacency_list.hpp: typedef BOOST_STD_EXTENSION_NAMESPACE::hash_set<ValueType> type; adjacency_list.hpp: struct bind_ { typedef BOOST_STD_EXTENSION_NAMESPACE::hash_set<T, std::less<T> > type; }; adjacency_list.hpp: struct bind_ { typedef BOOST_STD_EXTENSION_NAMESPACE::hash_set<T, std::less<T> > type; }; should slist be handled the same way as hash_set ? thanks weiqing //======================================================================= // Copyright 1997, 1998, 1999, 2000 University of Notre Dame. // Authors: Andrew Lumsdaine, Lie-Quan Lee, Jeremy G.
