How do i access graph property?
by Jef Driesen 31 Jan '06

31 Jan '06

Suppose I have defined the following graph: typedef boost::adjacency_list< boost::setS, // Adjacency list boost::setS, // Vertex list boost::undirectedS, // Undirected graph unsigned int, // Vertex property (unique label) boost::no_property, // Edge property unsigned int, // Graph property (next unique label) boost::listS // Edge list > graph; How do I access the graph property? For the vertex property this is a very simple operation: graph g = ...; vertex_descriptor u = ...; vertex_property label = g[u]; But I can't find a way to access property associated with my graph. How can I do this?

Boost Graph Library - heap profile
by Dave 31 Jan '06

31 Jan '06

Hello All, I am looking into heap profiles of some example programs given in Boost Graph Library and I would like to know if there is any garbage collection or memory compaction done by BGL's memory allocator. Thank you. Dave --------------------------------- Bring words and photos together (easily) with PhotoMail - it's free and works with your Yahoo! Mail.

[serialization] Problem with multiple multi-index keys.
by Toby Smith 31 Jan '06

31 Jan '06

Hi, I'm having a problem serializing a multi-index container. Serialization used to work fine, until I added a second (non-unique) key to the container. I've managed to distill the problem down to a small bit of code, so here it is. Uncomment the #define to see the segfault at serialization time in action, leave it commented and the example code works fine. I'm clearly missing something subtle (or not-so-subtle) here, but I don't have the first clue what it might be. Suggestions are enormously appreciated. Regards, tob ---------------------------------------------------------------------------- // A simple program to illustrate my crazy serialization problem with // multi-index containers.

Iterators and algorithms
by Jiri Palecek 31 Jan '06

31 Jan '06

Hello, I have recently tried to implement merging of more lists (or union of more sets). The (somewhat silly) approach would be set<X> ret,ret2; for(list<set<X> >::iterator it=sets.begin(),end=sets.end();it!=end;++it) { set_union(ret.begin(),ret.end(),it->begin(),it->end(),inserter(ret2)); ret.clear(); swap(ret,ret2); } and ret is the result. However, it seems to me that these temporaries are unnecessary. So I wonder wheter there could/should be some class of iterators that implemented some STL algorithms. There is already an iterator that could replace the unary version of transform (transform_iterator) In my case, I'm talking about some merge_iterator that would merge two sorted sequences (being an input iterator). That is, copy(merger(a.begin(),a.end(),b.begin(),b.end()),ostream_iterator(cout)) would be equivalent to merge(a.begin(),a.end(),b.begin(),b.end(),ostream_iterator(cout)) and similarly for set_union etc. Is it possible to have such iterators?

Ok, I am using VC++ 6, SP5.

boost bind logical operators question
by gast128 31 Jan '06

31 Jan '06

Dear all, this new boost bind logical operators is a great enhancement for readability of bind constructions. However I have not found out yet how to deal with e.g. built in types: std::vector<int> vec; std::list<int> lst; //copy_if does not exist in std, I know. std::copy_if(vec.begin(), vec.end(), std::back_inserter(lst), ...); this ... must now boost::bind(std::equal_to<int>(), _1, nNumber), which is quite unreadable, but no such thing like boost::bind::_1 == nNumber (like boost::lambda)? Wkr, me

lexical_cast memory consuption with VC8

31 Jan '06

Hi, I'm experiencing a memory leak while using lexical_cast with VC8. The leak was detected by an end-user in a long-running application and evidenced with GlowCode (a leak detection tool). The origin seems to be an allocation inside ios_base (<xiosbase>).

[program_options] Bug in example and documentation
by Peter Gerell 31 Jan '06

31 Jan '06

Hi, I believe the example found in example/response_file.cpp and referenced in the documentation has a bug. In the following code fragment a temporary string object is passed as the first argument to the tokenizer constructor. This string is destroyed before the iteration over the tokens start. /Peter if (vm.count("response-file")) { // Load the file and tokenize it ifstream ifs(vm["response-file"].as<string>().c_str()); if (!ifs) { cout << "Could not open the response file\n"; return 1; } // Read the whole file into a string stringstream ss; ss << ifs.rdbuf(); // Split the file content char_separator<char> sep(" \n\r"); tokenizer<char_separator<char> > tok(ss.str(), sep); vector<string> args; copy(tok.begin(), tok.end(), back_inserter(args)); // Parse the file and store the options store(command_line_parser(args).options(desc).run(), vm); }

Request help with boost::compose to boost::bind conversion
by gdprosch＠micron.com 30 Jan '06

30 Jan '06

Let me apologize in advance for my ignorance but I have not been able to update the following code successfully in order to migrate from Boost 1_29 to 1_33. Despite reading the boost::bind documentation a few times I am failing to make the necessary connection regarding the use of _1, _2 and handling the use of DeRef in the equal function below. // Unary dereference functor (a functor that returns the value of the specified // parameter, dereferenced via operator*) // (Note: This DeRef code is included in a separate header.) template < class Ptr, class T > struct DeRef : public std::unary_function< Ptr, T > { T & operator()( Ptr & ptr ) const { return *ptr;} }; // --- // Compare LocalStringMap (a custom map container with Tag/Value pair). // A TagValue is a class that contains a tag and a value (both strings) // A TagValuePtr is a custom, dereferencable smart pointer. inline bool LocalStringMap::operator==( const LocalStringMap &that ) const { // Must be same size if( this->size() != that.size() ) { return false;} return equal( this->_list.begin(), this->_list.end(), that._list.begin(), boost::compose_f_gx_hy( equal_to< TagValue >(), DeRef< const TagValuePtr, const TagValue >(), DeRef< const TagValuePtr, const TagValue >() ) ); } Any assistance with this would be most helpful. I get the impression that I do not need to use the DeRef class the original author created given boost:bind's more capable traits identification. Here's what I have so far... return std::equal( this->_list.begin(), this->_list.end(), that._list.begin(), boost::bind<bool>( std::equal_to< TagValue >(), ???

After mulling a bit, I think this is the whole point of shared_ptr. But I am not sure how it works. Is this encapsulated in the check_delete?

Boost shared pointers and MSVC++ 6.0
by Henri Herscher 30 Jan '06

30 Jan '06

Hi, I'm making heavy use of the boost shared pointers in the open source audio recording (voip and sound devices) project I'm developing (http://www.oreka.org) The software is cross platform (Windowns/Linux) and shared pointers are created in plugins and typically destroyed in other plugins or in the main program. Under linux, I haven't had any kind of problem. On windows however, using MSVC++ 6SP6 I have observed strange crashes that happen only in the release mode. So far I think I have been able to solve that doing two things (both needed or crash !): 1. Make sure all DLLs and the main program are compiled with the same runtime (multithreaded DLL) 2. Make sure all DLLs and the main program are compiled with inline function exapansion disabled My questions: * Is this normal ? What have other people experienced ? * Will this go away if I upgrade to MSVC++ 7 ? Thanks Henri

How will it work if the main program is linked against the multi-threaded dll and some other library the single-threaded, but the object that was created in the MT-linked dll is deleted by the one in the ST-dll? Wouldn't different deletes be called?

Is this a new adherance to the standard by g++ 4.0.2? I didn't used to have to add the initializer to get it to link. This is troublesome with boost::recursive_mutex because it is noncopyable. How do I specify an initializer for it? Is it just not possible to have a mutex static member? -Dave

Im using visual c++ 2005 with windows xp SP2 and when I tried to build my project I get the following error: fatal error C1083: Datei (Include) kann nicht geöffnet werden: "boost/algorithm/string.hpp" corrosponding to that line of code: #include <boost/algorithm/string.hpp> All # include calls have a unix like path description and not a common windows path like : c:\boost\include\algorith\string.hpp. That seems to be a general problem with all #include calls in all boost *.hpp files. I have included the the path[c:\boost] and [c:\boost\include] to my VC++ INCLUDE Path. Can somebody please help. -Frank

[random] comments on speed?
by Sanyi 30 Jan '06

30 Jan '06

Sorry if double posted... Can anyone who have tried Boost's `random' library have any thoughts on its speed? I looked into its binomial variate function and apparently it actualy flips a (biased) coin countless times to generate it. I am not an expert in this, but this seems awfully slow for high n's. (Not to mention that I could have done it myself.) AFAIK there are fast and good algorithms/approximations for generating some non-uniform variates. Are any of these at least planned to be included? <OT> I've found some papers on fast binomial generators, but that takes some serious time and effort to translate into working code. As I don't want to reinvent the wheel, if you know of any publicly available libraries for it, let me know. </OT> Thanks, Sanyi

boost::iostream - no way to set failbit or badbit in stream from device?
by Oliver.Kowalke＠infineon.com 30 Jan '06

30 Jan '06

Hallo, how can I set failbit or badbit in boost::iostream::stream if I detect some error in boost::iostream::device::read/write? Is it possible without throwing exceptions? Example: in the write method of a device which models a socket connection an EPIPE error (peer has closed socket) was detected. How can I set the boost::iostream::stream (which uses the device) to be not useable? Regards, Oliver

Hello Petro, >> would the eofbit be set if I return EOF in device::write? >> How can I set failbit from device? >Does it make sense for write to return EOF? >EOF means "no more data". >But writing is inserting data, not requesting it. If you write to a socket and the peer has already closed the socket you get an EPIPE error. How would you propagate this to your application? Oliver

[boost][serialization] How to implement serialization classes in two DLLs
by jf332-3 29 Jan '06

29 Jan '06

Hi, After few hour on the subject, Im would like to have some explanations & recommendations one the boost serialization library. To explain, my problem, you will find hereafter a VC++ 7.1 project that demonstrates it. Problem Description We have involved in a large project with for example two DLLs libraries: LibA and LibB. These libraries define & implement one class each other, lets say libA::A and libB::B. These two classes can be serialized through boost serialization engine. The interfaces for the two classes are the same: ---------------------- struct LIBA_API A { std::vector<double> my_vector ; private: friend class boost::serialization::access; template<class Archive> void save(Archive & ar, const unsigned int version) const ; template<class Archive> void load(Archive & ar, const unsigned int version) ; BOOST_SERIALIZATION_SPLIT_MEMBER() }; LIBA_API void save(const libA::A* pObj, std::ostream& os) ; LIBA_API void load(libA::A* &pObj, std::istream& is) ; }; // Namespace libA ---------------------- The two free functions save() and load() are defined to be able to serialize the class libA::A (respectively the class libB::B). When, we try to use these interfaces in an EXE application: ---------------------- #include <LibA/A.h> #include <LibB/B.h> #include <boost/filesystem/path.hpp> #include <boost/filesystem/fstream.hpp> #pragma comment(lib, "liba_d.lib") #pragma comment(lib, "libb_d.lib") int main(int argc, char* argv[]) { libA::A a; libA::save(&a, boost::filesystem::ofstream("a.xml")); libB::B b; libB::save(&b, boost::filesystem::ofstream("b.xml")); // -> Assert in debug mode return 0; } ---------------------- The figure hereafter describes the relationships between LibA, LibB and EXE. ------------ ------------ | LibA | | LibB | ------------ ------------ \ / \ / Exe Application We have to face to an assert in debug mode generate by the file boost::serialization::extended_type_info.cpp, line#71. This assert happens during the instance serialization of class libB:B. Recently, there are some posts on this subject, but I would like to known how I can deal with this assert? Is it possible to avoid it by a code organisation? To have a concrete answer, I have joined my complete VC++7.1 project. Thanks in advance for your help.

Re: [Boost-users] boost::serialisation - portable_binary_oarchivenotpart of library
by Oliver.Kowalke＠infineon.com 28 Jan '06

Hello Robert, I think a 'finished' protable_binary_oarchive/ protable_binary_iarchive would be very useful for network applications (passing message structures -> header, body, trailer). I'm not familiar with boost::serialization (my first look into it) - I see some specializations of load for integral types an a templated member function for all others. Serialisation for std::strings and chars are supported in a portable manner? Only floating point types have to be implemented for portability? Oliver >I made it as an example on how to extend the library by deriving from an >existing >archive. To "finish" it would require implementing serialization of >floating point >types in a portable manner and this turns out to be a non-trivial task. >Implementing >this would be too much work and would sort of compromise illustrative value >of the example.

Yes. Each class you want to serialize needs a default constructor in addition to whatever other constructors your application needs. Merrill

Before I'll investigate more I'd like to know if anybody knows why it is not allowed a rule object inside this directive: token_node_d.
