[serialization] DLL woes
by Anders Wang Kristensen 07 Jul '07

07 Jul '07

Hi, I'm trying to serialize a class using two functions located in different DLLs. I can serialize fine by calling one function, but when I call the second it triggers an assertion in extended_type_info.cpp: // make sure that attempt at registration is done only once assert(lookup(eti) == m_self->m_map.end()); Apparently the class is registered twice, but how do I avoid that? -- Anders

[1.34.0][serialization][iostreams] Memory leaks

The attached code works fine with version 1.33.1 but generates memory leaks with 1.34.0. Not sure it's a bug in Serialization or Iostreams.

[Graph] I could not get the reversed graph!
by jiangfan shi 06 Jul '07

06 Jul '07

HI, All, I could not get a instance of reversed graph by calling make_reverse_graph(g). That is, I have following type: typedef adjacency_list< listS, listS, bidirectionalS, property<vertex_index_t, std::size_t>, no_property> G; typedef reverse_graph<G, G&> ReverseG; //Maybe something wrong here. After I call make_revserse_graph(G) as following, I could not get a instance of modified graph by accessing some fields of ReverseG. ReverseG tmp=boost::make_reverse_graph(g); //I try to get the reservsed graph here. The only field is tmp.m_g, which is G& type and the original graph, but is not the reversed graph. Thanks. Jiangfan

[variant] recursive_variant_ broken with VC++ 2005 SP1
by Cory Nelson 06 Jul '07

06 Jul '07

Hello, Using 1.34.0 and 1.34.1 RC, this used to work with 2005 but with SP1 it is now broken: boost::make_recursive_variant< int, std::pair<int, boost::recursive_variant_> >::type foo; It now gives the error: utility(54) : error C2079: 'std::pair<_Ty1,_Ty2>::second' uses undefined struct 'boost::recursive_variant_' with [ _Ty1=int, _Ty2=boost::recursive_variant_ ] I was able to fix this by #defining BOOST_VARIANT_NO_FULL_RECURSIVE_VARIANT_SUPPORT before including variant.hpp. - Cory

question about boost serialization library
by Fei Liu 06 Jul '07

Hello, I am trying out the boost serialization library. I've gotten demo_xml.cpp to work correctly. Now I want to serialize a customized class but I got some errors I don't fully understand.

Python rules for compiling in Mac OS X
by Antony Chazapis 06 Jul '07

06 Jul '07

Hi all. It seems that the tools/build/v2/tools/python.jam file is broken when used in Mac OS X (darwin). I had many problems when trying to compile libtorrent's python bindings using bjam and they all were finally solved by changing this file. I would suggest applying the following patch to the code. This fixes the missing "python_for_extensions" rule problem, and allows for properly setting the include paths (without relying on env vars). For linking I just used "-framework Python". I don't get what all the $ (PYTHON_FRAMEWORK) stuff is about. With the "official" python install, gcc automatically finds the framework. However, there is still an issue: In rule "init-mac" the "root" variable should not be necessary. When I tried to change that, compilation broke again. I guess there are references to the variable elsewhere that have to be changed first. For now I can compile everything by setting (in user-config.jam): using python : 2.5 : /Library/Frameworks/Python.framework/Versions/2.5 ; Hope this helps, as it should apply to other python-related projects as well.

circular_buffer / not added (from 2004 ??)
by Ruediger Berlich 06 Jul '07

Hi there, http://www.boost.org/more/formal_review_schedule.html lists the circular_buffer library by Jan Gaspar as "Accepted -- not added yet". This is an entry from March 2004 . Does anyone have information what the status of that library is ? In any case Thanks and Best Regards, Ruediger

[regex] why character class [:xdigit:] does not work in my sample example ??
by Chandan Nilange 06 Jul '07

06 Jul '07

Hello, Why does the boost regex sample program attached here, doesnot generate match for character class [:xdigit:] Do we need to enable this character class explicity? If yes, how to enable it?
