Boost Threads documentation
by James Hughes 01 Feb '06

01 Feb '06

Hello all, I am reading thought he thread docs on the Boost site, which are all dated around 2004/2005. Is there any more recent documentation, as this stuff refers to features not yet present, which I think are there now. James

Re: [Boost-users] trying to install Boost 1.33.1 on Solaris 5.9 + SunStudio 11

Thank you everybody for you help, The SUN patch solved my problem.

I've been experimenting with those with a view to run Boost regression tests on Solaris (10 in my case) and with the latest patchset installed it will still fail to compile about 60 to 80 targets out of the close to 1300 for the 'stage' target. In my experience this is the best result for any Sun compiler so far. As mentioned in the other email it is worth compiling it against stlport and not the older RogueWave library.

trying to install Boost 1.33.1 on Solaris 5.9 + SunStudio 11

Hello, I'm trying to install Boost 1.33.1 on a Sun Solaris 5.9 Sunpro 11 and after the command: bjam "-sTOOLS=sunpro" install I receive the error message: >> Assertion: (../lnk/init.cc, line 1032) while processing /ftx/opt/SUNWspro/prod/include/CC/Cstd/rw/messages.cc at line 0. >> Assertion: (../lnk/init.cc, line 1032) while processing /ftx/opt/SUNWspro/prod/include/CC/Cstd/rw/messages.cc at line 0. Do you know how I can solve this problem? It looks like Sun has released a patch to solve the error "Assertion: (../lnk/init.cc, line 1032)" but I can't find it for solaris 5.9 + Studio 11 Regards Xavier ************************************************************************* Ce message et toutes les pieces jointes (ci-apres le "message") sont confidentiels et etablis a l'intention exclusive de ses destinataires.

Re: [Boost-users] Getting started with Boost: what did you need to know?
by Merrill Cornish 01 Feb '06

David, Having an introductory video to _Boost_ is problematic since there's no one thing called "Boost". Instead, it's a collection of often disparate libraries. Each of the libraries could reasonably be featured in its only "getting started" video. However, if the point is to _sell_ the whole Boost idea, then one alternative would be to bypass the details of syntax and function calls of the various libraries in favor of a "Why do you need Boost" talk/pitch/video. Talk about what kind of everyday problems it solves for you rather than trying to explain the nitty gritty (and 200 levels of nested template declarations) of each library. The pitch would verbally sketch (i.e. probably no code) a real world programming problem, then point out what the Boost library has to help out. A series of problem sketches would allow the pitch to cover a lot of otherwise disjoint Boost functionality and still make sense. Merrill

[BGL] adjacency_list: OutEdgeList vs EdgeList
by Johan Oudinet 31 Jan '06

31 Jan '06

Hi, I can't understand the difference between the OutEdgeList and EdgeList adjacency_list parameters. I think the documentation is unclear about EdgeList (especialy http://www.boost.org/libs/graph/doc/using_adjacency_list.html which has a section about "Choosing the Edgelist and VertexList" but only OutEdgeList and VertexList are present in this section) I need fast access to edge_properties from edge_descriptor. But I couldn't find if OutEdgeList or EdgeList container is used for the operator[] ? I read that EdgeList doesn't exist in previous version of the BGL and OutEdgeList was called EdgeList. So I suspect their are still mistakes in the adjacency_list documentation. Regards, -- Johan Oudinet

[filesystem] mistakable documentation
by marcoh77＠freenet.de 31 Jan '06

31 Jan '06

Hello! Is it possible to expand the filesystem documentation? ---8<------------------------ Native paths should be created with the 'native' argument, like this: boost::filesystem::path p("C:/test.txt", native); ---8<------------------------ For a novice it's impossible to create a path objekt with a native syntax because it's missing in the beginner tutorial. I have tried to create a path object and I got only exceptions. After a long journey in google and the boost mailinglists I have found a source example with the native argument. The documentation of boost::filesystem doesn't explain this part in the beginners guide as expected. Of course it is explained in the detailed documentation, but this is to far away. ;-) I hope my suggestion will be accepted. Thanx! :-) Best regards Amin

Maybe this is somewhat off topic but I didn't want the idea to get lost. What about having a getting-started-video for Boost. Maybe someone could film Davids 'Getting started with Boost' sessions. -- Marco Wahl icq 284789053

Compile error with serialization
by cheesy4poofs 31 Jan '06

31 Jan '06

I'm using Windows XP with Visual Studio 2003. I've compiled boost 1.33.1 successfully with bjam and installed the libs and DLLs into my environment. I started playing with the serialization library. I created a win32 console project and copied in the demo.cpp serialization program. It compiles and runs just fine. I then started added serialization to my own project and started running into problem after problem. I've since commented out all my own code except for the following: I copied the gps_position class directly from demo.cpp into my project. At the top of the file, I've included the following files: #include <boost/serialization/type_info_implementation.hpp> #include <boost/archive/text_oarchive.hpp> #include <boost/archive/text_iarchive.hpp> #include <boost/serialization/base_object.hpp> #include <boost/serialization/utility.hpp> In my class Manager, I wrote the following method: void Manager::save(const std::string & filename) { boost::recursive_mutex::scoped_lock lock(_nodeMutex); std::ofstream outFile; outFile.open(filename.c_str(), std::ios::binary); boost::archive::text_oarchive archiveFile(outFile); // simple test const gps_position g; archiveFile << g; outFile.close(); } Trying to compile, I get the following errors: ..\API\inc\boost\archive\detail\oserializer.hpp(131) : error C2027: use of undefined type 'boost::serialization::extended_type_info_null<T>' with [ T=gps_position ] ..\API\inc\boost\archive\detail\oserializer.hpp(131) : see reference to class template instantiation 'boost::serialization::extended_type_info_null<T>' being compiled with [ T=gps_position ] ..\API\inc\boost\archive\detail\oserializer.hpp(128) : while compiling class-template member function 'bool boost::archive::detail::oserializer<Archive,T>::is_polymorphic(void) const' with [ Archive=boost::archive::text_oarchive, T=gps_position ] ..\API\inc\boost\archive\detail\oserializer.hpp(264) : see reference to class template instantiation 'boost::archive::detail::oserializer<Archive,T>' being compiled with [ Archive=boost::archive::text_oarchive, T=gps_position ] . . . *snip* As far as my project settings, I'm compiling a win32 DLL, with the Multithread Debug C++ standard library DLL. I have exceptions and RTTI enabled. Basically the same settings I used for compiling demo.cpp. If I comment out the "archiveFile << g;" line, it compiles fine. Any help would be greatly appreciated! Thank you, Scott

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

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.
