VS2012: libboost_filesystem-vc110-mt-gd-1_54.lib missing
by Amann, Julian 15 Jul '13

15 Jul '13

Hello, I built boost 1.54.0 with Visual Studio 2012 x64. I tried to build a small demo that is using boost filesystem: ///////////////////////////////////////////////////////////////////// #include <iostream> #include <boost/filesystem.hpp> using namespace boost::filesystem; int main(int argc, char* argv[]) { if (argc < 2) { std::cout << "Usage: tut1 path\n"; return 1; } std::cout << argv[1] << " " << file_size(argv[1]) << '\n'; return 0; } ///////////////////////////////////////////////////////////////////// CMake is used to setup the corresponding project for VS2012 x64: ################################################# CMAKE_MINIMUM_REQUIRED(VERSION 2.8.9) PROJECT(FilesystemTest) set_property(GLOBAL PROPERTY USE_FOLDERS ON) SET(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/build/) # Visual Studio 2010 Pro Standard: /DWIN32 /D_WINDOWS /W3 /Zm1000 /EHsc /GR SET(CMAKE_CXX_FLAGS "/DWIN32 /D_WINDOWS /W4 /Zi /EHsc /GR- /MP /openmp") SET(CMAKE_DEBUG_POSTFIX "d") FIND_PACKAGE(Boost COMPONENTS filesystem system REQUIRED) # Unicode rules!

Previously I used boost 1.53.0 - everything was working perfect when using boost 1.53.0. When looking into the boost 1.54 lib folder there is only a 'boost_filesystem-vc110-mt-gd-1_54.lib' and a 'libboost_filesystem-vc110-mt-sgd-1_54.lib' I compiled boost using this instructions: 1. Download boost 1.54.0 from http://www.boost.org/ 2. Extract files (e.g. "C:\thirdparty\vs2013\x64\boost_1_54_0") 3. Start Visual Studio 2012 x64 command prompt 4. Change to boost directory (e.g. "cd C:\thirdparty\vs2010\x64\boost_1_54_0") 5. Execute .\bootstrap.bat 6. Execute b2 address-model=64 toolset=msvc-11.0 --build-type=complete stage BTW: If only certain libraries (for instance filesystem) are need step 6 can be replaced by this: b2 address-model=64 toolset=msvc-11.0 --build-type=complete stage --with-filesystem --with-signals --with-system I could not figure out what is working wrong. Any ideas? Best regards Julian

[serialization] unregistered class exception during serialization from DLL
by Andreas Mainik 14 Jul '13

14 Jul '13

Hello All, I have some classes needed to be serialized (A.HPP und A.CPP below). The serialization happens over the pointer to the base class. The code is called in the function (FUNC.CPP below). The files A.HPP, A.CPP and FUNC.CPP are constituents of a bigger DLL-library. If my test application is linked dynamical against the DLL-libary then the code throws an exception "unregistered class - derived class not registered or exported". What is wrong in my code? The code is compiled with Visual Studio 2012 (default settings). Boost: 1.53.0 If I look into BOOST_SERIALIZATION_DECL(const extended_type_info *) extended_type_info_typeid_0::get_extended_type_info( const std::type_info & ti ) const { typeid_system::extended_type_info_typeid_arg etia(ti); const tkmap & t = singleton<tkmap>::get_const_instance(); const tkmap::const_iterator it = t.find(& etia); if(t.end() == it) return NULL; return *(it); } then I see that Ord<Options> is not registered in singleton<tkmap>::get_const_instance(). Moreover, I am not able to set breakpoint into Ord<Options>::serialize(). According to MSVC debugger the breakpoint will not be hit. Additional remarks: 1) If I uncomment the code lines in FUNC.CPP then everything works. 2) If I link the code statical to my test application then everything is also fine. -----------------------A.HPP----------------------------------------------- #include "archive.hpp" // includes the required headers struct OrdBasis { virtual ~OrdBasis() {} virtual bool is_base_of(const boost::shared_ptr<OrdBasis>& derived_ptr) { return true; } private: friend class boost::serialization::access; template<class Archive> void serialize(Archive & ar, const unsigned int /* file_version */){ } }; template<typename P> struct Ord; struct Options { Options() {} friend class boost::serialization::access; template<class Archive> void serialize(Archive & ar, const unsigned int /* file_version */){ } }; template<> class Ord<Options> : public OrdBasis { typedef Ord<Options> P; bool is_base_of(const boost::shared_ptr<OrdBasis>& derived_ptr) { const boost::shared_ptr<P> base_ptr = boost::dynamic_pointer_cast<P>(derived_ptr); bool result = (base_ptr) ? true : false; return result; } private: friend class boost::serialization::access; template<class Archive> void serialize(Archive & ar, const unsigned int /* file_version */){ ar & BOOST_SERIALIZATION_BASE_OBJECT_NVP(OrdBasis); } }; BOOST_CLASS_EXPORT_KEY(Ord<Options>) -----------------------A.HPP------------------------------------------- -----------------------A.CPP------------------------------------------- #include "A.hpp" BOOST_CLASS_EXPORT_IMPLEMENT(Ord<Options>) -----------------------A.CPP------------------------------------------- I serialize with following sequence ---------------------FUNC.CPP------------------------------------------ void serializeFunc() { namespace io = boost::iostreams; typedef std::vector<char> buffer_type; buffer_type buffer; buffer.reserve(2000000); { buffer.clear(); io::stream<io::back_insert_device<buffer_type> > output_stream(buffer); boost::archive::binary_oarchive oa(output_stream, boost::archive::no_header); // begin //if the following lines are commented out then everything works //boost::shared_ptr<Ord<Options>> testOptOrd(new Ord<Options>); //oa & testOptOrd; //end boost::shared_ptr<OrdBasis> testOptOrdB(new Ord<Options>); oa & testOptOrdB; } { io::basic_array_source<char> source(&buffer[0],buffer.size()); io::stream<io::basic_array_source <char> > input_stream(source); boost::archive::binary_iarchive ia(input_stream, boost::archive::no_header); boost::shared_ptr<OrdBasis> testOptOrd; // begin linked to the above code block //ia & testOptOrd; // end ia & testOptOrd; int i = 0; } } -----------------------FUNC.CPP------------------------------------ -- Using Opera's revolutionary email client: http://www.opera.com/mail/

[Boost.Geometry] - Union generates polygon with punctures
by Olivier Heriveaux 14 Jul '13

14 Jul '13

Hello ! I'm trying to use Boost.Geometry library to implement Minkowsky algorithm (i.e. polygon convolution). I try to implement it in the same way Boost.Polygon does, but during the algorithm execution, a boost::geometry::overlay_invalid_input_exception is raised. It seems that one of the input polygons to the union_ function is invalid. To understand my mistake, I outputed the operand polygons to SVG files and I discovered punctures in one of them. I believe Boost.Geometry thinks my polygon is self-intersecting (may be due to precision error with floats ?) - but this polygon itself is the result of a previous union operation. For info, I attached the SVG file (use inkscape to see it completely since segments are out of the box due to negative coordinates). I don't know if solutions to this problem exists or if the library is faulty (the bad polygon is the result of an union operation). One workaround would be to detect punctures and remove them, but it's kind of ugly imho... Some more details: - point coordinates type is float, - I use custom class instead of point_xy model, - polygon winding is counter-clockwise. Thank you in advance for any help, Olivier

[multi_index][ann] Boost.MultiIndex 1.55 preview: major update with C++11 capabilities
by Joaquín Mª López Muñoz 14 Jul '13

14 Jul '13

Dear Boost.MultiIndex user: I've completed a major update of Boost.MultiIndex retrievable from the SVN repository, trunk branch, or at: https://www.dropbox.com/s/xipv129az88vgd1/multi_index_130713.zip This update includes many C++11 capabilities (most emulated by various means in pre-C++11 compilers,) among them the following: * multi_index_container is now efficiently movable employee_set extract_employees(const std::string& db); employee_set cont=extract_employees("employees.dat"); // no data copying * Initializer lists supported (if the compiler provides them) employee_set es8{{0,"Rose",40,4512},{1,"Mary",38,3345},{2,"Jo",25,7102}}; * Emplace functions es.emplace(0,"Joe",31,1123); es.get<3>().emplace_back(3,"Judy",39,6201); * Non-copyable elements allowed typeded multi_index_container< std::unique_ptr<employee>, indexed_by<...> > employee_ptr_set; How does this update affect you? 1. Of course, you can now begin using the new capabilities, even in non-C++11 compilers with some limitations (explained at the documentation). 2. Your code can get some transparent performance gain without you doing anything es.insert(employee(4,"Jill",52,3379)); // temporary's moved rather than copied 3. The internal code has been refactored to implement the new features, and this refactoring touches on preexisting functionality, hopefully without producing regressions --this has been thoroughly tested, but: It is now #3 that worries me the most: if you use Boost.MultiIndex and have some time to test this preview with your code, please do so and report the results. The more this update is tested before the official release, the less problems it will cause (ideally none.) As the update is major, every bit of testing helps. Hope you enjoy the new features.

Boost.Log SimpleEventLog question
by Pieter 13 Jul '13

13 Jul '13

LS, I am currently configuring my logging configuration using a property tree. When I include a SimpleEventLog sink, how can I apply an event type mapping to that sink? In the stated example this is done before the sink is added to the core: typedef sinks::synchronous_sink< sinks::simple_event_log_backend > sink_t; boost::shared_ptr< sink_t > sink(new sink_t()); sinks::event_log::custom_event_type_mapping< severity_level > mapping("Severity"); // . define mapping here . sink->locked_backend()->set_event_type_mapper(mapping); // Add the sink to the core logging::core::get()->add_sink(sink); but adding the sink happens behind the scenes when using the configuration utilities. BTW, in the section "Simplified library initialization tools" of the documentation Table 1.15 seems to miss a 'Format' parameter that I assume is still needed? Many thanks, Pieter

[Boost.Log] More queries
by Leo Carreon 12 Jul '13

12 Jul '13

Hi everyone, As I have mentioned in a previous post, I have been trying to learn how to use Boost.Log. I have been experimenting with logging to a file with filtering and specifying the log formatting in three different ways, namely: 1. Specifying the log formatting using a lambda type expression. 2. Specifying the log formatting using a plain text string with placeholders for the attributes that I have defined. 3. Specifying the log formatting in a settings file. (However, the formatting string is exactly the same as in 2 above.) I have attached a copy of my source code and settings file. Note that I comment out parts of the source code file depending on which option I use above. The problem I’m encountering is when I use options 2 & 3 above, the severity level string does not appear in the log. But if I use option 1, the severity level string appears as expected. It is my understanding that severity level is a pre-defined attribute when using a severity_logger. Am I missing something when using options 2 & 3? If I decide to use my own severity level enumeration, what do I need to do? Kind regards, Leo

Re: [Boost-users] Query on Boost.Log
by Leo Carreon 12 Jul '13

12 Jul '13

From: Leo Carreon Sent: Friday, July 12, 2013 8:42 AM To: Boost Users Mailing List Subject: Query on Boost.Log Hi everyone, I’m trying to learn how to use Boost.Log from Boost 1.54.0 on Fedora 18. When I attempt to call boost::log::init_from_stream() even with BOOST_LOG_DYN_LINK defined, I get the error message”undefined reference to `void boost::log::v2_mt_posix::init_from_stream<char>(std::basic_istream<char, std::char_traits<char> >&)'” for the line where I called the function. Note that I have included the header file “boost/log/utility/setup/from_stream.hpp” and added –lboost_log to my link command line. Am I missing something. I have noticed that boost::log::init_from_stream() is a template. Is an instance of this template added into the shared library? Kind regards, Leo Hi again everyone, FYI. I built Boost 1.54.0 using the following bjam options – link=shared runtime-link=shared I have also checked the build logs from the above and discovered that not all of the .cpp files in libs/log/src have been included during the build. Kind regards, Leo

[exception] exception_ptr missing virtual base parameters
by Michael Caisse 12 Jul '13

12 Jul '13

The basic problem I'm experiencing is that getting an exception_ptr results inherited parameters getting lost when virtual inheritance is used. The code below demonstrates a simple example. "bar" is lost in the print. Changing derived_except to be: struct derived_except : base_except { int i; }; will cause the inherited values to be copied into the exception_ptr; however, this has all the standard problems associated that come with not using virtual inheritance. This looks like a bug to me. The C++11 equivalent behaves has expected and inherited values are maintained in the exception_ptr. Any thoughts? michael -------------- boost::exception_ptr version -------------- #include <boost/exception/all.hpp> #include <string> #include <iostream> struct base_except { std::string s; }; struct derived_except : virtual base_except { int i; }; int main() { derived_except e; e.i = 8; e.s = "bar"; boost::exception_ptr ptr = boost::copy_exception(e); try { boost::rethrow_exception(ptr); } catch(derived_except & e) { std::cout << "derived_except: " << e.s << " " << e.i << std::endl; } catch(...) {} return 0; } -------------- c++11 version --------------------- #include <exception> #include <string> #include <iostream> struct base_except { std::string s; }; struct derived_except : virtual base_except { int i; }; int main() { derived_except e; e.i = 8; e.s = "bar"; std::exception_ptr ptr = std::make_exception_ptr(e); try { std::rethrow_exception(ptr); } catch(derived_except & e) { std::cout << "derived_except: " << e.s << " " << e.i << std::endl; } catch(...) {} return 0; } -- Michael Caisse ciere consulting ciere.com

Re: [Boost-users] [graph] in-depth parsing and modifications of the graph

I mean traverse when i said parse. So the problem is i can't traverse in depth-first order my graph and modify node (or edge) properties. I wrote a basic case which doesn't work. ----------------------------------------- // Begin main.cpp #include <boost/graph/adjacency_list.hpp> #include <boost/graph/depth_first_search.hpp> #include <vector> // Node properties struct MyNode { int node_id; MyNode() : node_id() {} MyNode(int id) : node_id(id) {} }; //Edge Properties struct MyEdge { int edge_id; MyEdge() : edge_id() {} MyEdge(int id) : edge_id(id) {} }; // Graph definition typedef boost::adjacency_list< boost::vecS, boost::vecS, boost::directedS, MyNode, MyEdge > MyGraph; typedef boost::graph_traits<MyGraph>::vertex_descriptor MyGraphVD; //My idiot visitor class my_dfs_visitor : public boost::default_dfs_visitor { public: template < typename Vertex, typename Graph > void discover_vertex(Vertex u, Graph & g) { // here i cant assign 0 to m node_id. however g is not cont..

I have the following error : ../main.cpp:35:3: erreur: assignment of member 'MyNode::node_id' in read-only object.
