05 Aug '10

Hi, any plans of implementing the inverse gamma distribution as part of the distributions library ? What about multivariate (in particular the multivariate normal and t distributions and Wishart and Dirichlet ) ? thanks, Thomas

boost serialisation and enable_shared_from_this versus 1.43
by Avi Bahra 04 Aug '10

04 Aug '10

In 1.42, boost serialisation is broken when used with a class that is derived from enable_shared_from_this. This was supposed to fixed in the next release., but the online release notes for 1.43 make no mention of this. Does any one know if it made it into1.43 ? Best regards, Ta, Avi

matrix function template for triangular_matrix and matrix datatypes
by Max S. Kaznady 04 Aug '10

04 Aug '10

Suppose we are working in namespace boost::numeric::ublas and I have 2 functions 1) template <class T> save_matrix(matrix<T> const &m) 2) template <class T> save_matrix(triangular_matrix<T,lower> const &m) and the code in both overloaded save_matrix functions is identical. How can I write a templated function which accepts any type of a matrix? I tried this, but it didn't work: template <class T> save_matrix(T const &m) Thanks, Max

[interprocess] shared memory, condtions, deadlock
by Kai Benndorf 04 Aug '10

04 Aug '10

Hi all, I'm trying to use the shared memory functionality of the boost interprocess library for implementing a client and a server like process, where the server calculates something for the client. I use condition variables for the process synchronization. The implementation works initially, but I am getting deadlocks, now. I appended a pseudo code example of my implementation. One instance of the SharedData class is hold in shared memory. On deadlock, both processes are hanging in the wait() functions. What am I doing wrong? Many thanks for any hint. Regards Kai

[conversion] lexical_cast doesn't throw
by Gaetano Mendola 04 Aug '10

04 Aug '10

Hi all, I'm in the process to migrate our application from RedHat 5.5 (gcc 4.1.2) to Ubuntu 10.04 (gcc 4.4.3), one regression test is not passing due the fact that lexical_cast is not throwing, this is the line: unsigned int myNumber = boost::lexical_cast<unsigned int>("-123"); I'm using boost 1.40 on both servers. I have noticed that the same executable compiled on Ubuntu 10.04 while on Ubuntu doesn't throw, running it on RH 5.5 throws, so it seems a system library problem. Trying with a simple stringstream, it seems that with the following code: std::stringstream myStream; myStream << "-123"; unsigned int myUInt; myStream >> myUInt; doens't set the fail bit on Ubuntu 10.04, but it does on RedHat 5.5. Does anyone have an idea on what is going on Regards Gaetano Mendola

Thread object pointers.
by Albert Schueller 04 Aug '10

04 Aug '10

Tue Aug 3 14:10:04 PDT 2010 Hi all, I'm trying to get up to speed on libboost's thread class using the tutorial information here: http://www.drdobbs.com/cpp/184401518 I'm curious why the two programs below seem to behave differently. In LISTING 1, three threads are declared as thrd1, thrd2, and thrd3 explicitly and each loops 10 times with random length sleeps. LISTING 2 is identical, except for the fact the three thread variables are allocated to boost::thread pointers. When I run LISTING 1 it appears that the threads are acting independently as I would hope. When I run LISTING 2, it seems that the threads are not independent, but rather thrd1 does its job, followed by thrd2, followed by thrd3. Am I not locking properly? Any help would be appreciated.

Open a filename with a wstring or wchar_t *
by Timothy Madden 03 Aug '10

03 Aug '10

Hello Surprisingly enough, C++ file-based streams can be opened with a char * string (for the filename) only, while modern computer systems have Unicode filenames. I see boost::iostreams::basic_file also gets constructed from a char * only. My project name has Korean characters, and I work on a Latin1 Windows system, and on my system the narrow-characters set simply does not contain Korean characters. Is there a (good) way to open a file with a wstring in boost ? Thank you, Timothy Madden

Problem with boost::bind, boost::shared_ptr and std::find_if algorithm
by przemyslaw.sliwa＠uk.bnpparibas.com 03 Aug '10

03 Aug '10

All, I have the following data sructure: struct WeightedTimeHolder { double time; double dt; double weight; double dailyVol; double varDelta_t; double cutToCutdailyVol; double extraVar; double varPlusEventVar; double aggrVar; double implVol; int cut; } and typedef multimap<int, boost::shared_ptr<WeightedTimeHolder> > DataMap. Now given value of cut in this data structure I would like to find the next position in DataMap which corresposnds to this gven value, I do it in the following manner: void nextPositionForCut(DataMap::iterator& pos, CutOffType cut) const { if((*pos).second->cut!=cut) while((*(++pos)).second->cut!=cut && pos!=m_pData->end()) {} // convert to boost::bind for better use! //pos = find_if(pos, m_pData->end(), boost::bind(&DataMap::value_type::second::value_type::cut, _1) == cut); } Since this looks really ugly I would like to ask you how this can be converto to find_if algorithm with a little help of boost::bind. I tried but could not succees. Thanks for help, Przemyslaw ___________________________________________________________ This e-mail may contain confidential and/or privileged information.

Question regarding using asn1 boost libraries
by Mupparthy Ravindranath 03 Aug '10

03 Aug '10

Dear friends, From the URL "http://www.ibusy.com/devtree/asn1/boost_asn1/linking.html", I learnt that boost has support for ASN1 (Abstract Syntax Notation) encoding and decoding using BER (Basic Encoding Rules). But when I downloaded the boost tar zip file, i could not find the below header file(s): #include <boost/asn1/asn1.hpp> Can someone help me where to get the ASN1 support header files for boost... Thanks and regards, RV

[Serialization] Diamond shaped inheritance and serialization methods specialization
by Robert Bigaignon 02 Aug '10

02 Aug '10

Hi all, I'm having trouble with Boost's serialization library that I'm trying to integrate with an existing class hierarchy that used MFC toolkit as the archiver. It seems that when a serializable class defines a specialized save (or load or serialize for that matter) in addition to the generic method, the serialization library gets confused and ends up not identify properly that the hierarchy of serializable classes uses multiple inheritance and in particular diamond-shaped inheritance. I've reproduced the problem using the test_diamond code example provided with Boost 1.43 using MS VC 9.0 by adding a save method specialized for archive::text_oarchive to the derived1 class defined in test_diamond.cpp. The following diff shows the implementation of this specialized method: -----8<----- --- ../temp/boost_1_43_0/boost_1_43_0/libs/serialization/test/test_diamond.cpp Wed Jul 14 11:28:02 2010 +++ ../serializationProto.cpp Wed Jul 28 13:05:47 2010 @@ -95,6 +97,13 @@ ar << BOOST_SERIALIZATION_BASE_OBJECT_NVP(base); } + template<> + void save(boost::archive::text_oarchive &ar, const unsigned int i) const + { + std::cout << "Saving (Text) derived1\n"; + ar << BOOST_SERIALIZATION_BASE_OBJECT_NVP(base); + } + template<class Archive> void load(Archive & ar, const unsigned int /* file_version */) { @@ -122,6 +131,7 @@ } BOOST_SERIALIZATION_SPLIT_MEMBER() + }; class final : public derived1, public derived2 { @@ -202,3 +212,219 @@ return EXIT_SUCCESS; } ----->8----- Adding the following function definition to will result in an access violation (see call stack bellow) in access.hpp @ line 136.

[multi_index] looking for "equal_to and less than"
by isjk 02 Aug '10

02 Aug '10

hi, I've got a structure like this, struct peer { int md5_; // unique key. int rank_; int degrees_; }; now, I need a composite_key, it can find equal_to "md5" and less than "rank_" and "degrees_" less than 8. eg: md5 rank degrees 2 0 8 2 1 5 2 2 0 2 6 3 4 3 1 4 5 0 f(2, 2) return (2 1 5) f(2, 1) return null f(2, 6) return (2 2 0)(2 1 5) f(4, 5) return (4 3 1) Thanks. -- View this message in context: http://old.nabble.com/-multi_index--looking-for-%22equal_to-and-less-than%2… Sent from the Boost - Users mailing list archive at Nabble.com.

Problem to substitute the std allocator with boost.asio and boost.filesystem
by watsonsong 02 Aug '10

02 Aug '10

I subsitute the std allocator with my own stl allocator, and defined a new string type like this: typedef std::basic_string<char, std::char_traits<char>, MySTLAllocator<char> > my_string; typedef std::basic_string<wchar_t, std::char_traits<wchar_t>, MySTLAllocator<wchar_t> > my_wstring; And I want to use them in my project, but I met some problem when I use boost.asio and boost.filesystem. The boost asio directly use std::string, I can not find a way to deal with it. I know I can pass a c style string char* to the asio, but it was less efficiency. When use the boost.filesystem, I tried this way, but I also met some problem: namespace MyNamespace { struct path_traits; typedef boost::filesystem::basic_path<my_string, path_traits> path; typedef boost::filesystem::basic_path<my_wstring, path_traits> wpath; struct path_traits { typedef my_string internal_string_type; typedef my_string external_string_type; static external_string_type to_external( const path &, const internal_string_type & src ) { return src; } static internal_string_type to_internal( const external_string_type & src ) { return src; } }; typedef boost::filesystem::basic_recursive_directory_iterator<path> recursive_directory_iterator; typedef boost::filesystem::basic_recursive_directory_iterator<wpath> wrecursive_directory_iterator; } namespace boost { namespace filesystem { template<> struct is_basic_path<MyNamespace::path> { BOOST_STATIC_CONSTANT( bool, value = true ); }; template<> struct is_basic_path<MyNamespace::wpath> { BOOST_STATIC_CONSTANT( bool, value = true ); }; } } namespace MyNamespace { inline bool is_directory( const path & ph ) { return boost::filesystem::is_directory<path>( ph ); } inline bool is_directory( const wpath & ph ) { return boost::filesystem::is_directory<wpath>( ph ); } } For replace all the function is a huge work, and in this way I can not replace it for I met this function, which is also use the std::string directly: BOOST_FILESYSTEM_DECL file_status status_api( const std::string & ph, system::error_code & ec ); Maybe this way is too bother, I think there must be an easy way to replace the string. Is there any way to resolve this? Thank you. -- View this message in context: http://old.nabble.com/Problem-to-substitute-the-std-allocator-with-boost.as… Sent from the Boost - Users mailing list archive at Nabble.com.

[Polygon] Test among 3 libraries
by TONGARI 01 Aug '10

01 Aug '10

Hi, I just modified a test program taken from AGG's examples to test the polygon clipping capability of following libraries. *Boost.Polygon *GPC *Clipper Here are some observations: 1) The proccesing speed (fastest to slowest): Clipper > GPC > Boost.Polygon 2) With "xor", although the results seems the same, they have different countours numbers (Clipper the least). 3) Boost.Polygon has a strange behavior that it sometimes produces erroneous vertical lines within the polygons. In this example, with "or" operation you'll see that. I put the test files here: *http://tinyurl.com/2axoqxc Anyone who wants to compile it will also need AGG and *Clipper on your computer.

Hi to all, I intended to use the boost.FSM library. I have install boot version 1.42 but the FSM lib is not there, only statechart. Did this library has been removed from boost?
