[boost][fusion] generate mpl::vector from fusion::vector
by Andrey Torba 24 Jun '09

How to generate fusion::vector from mpl::vector? How to generate mpl::vector from fusion::vector? BOOST_MPL_ASSERT((is_same< fusion::vector<int, char>, generate_fusion_vector<mpl::vector<int, char> >::type >)); BOOST_MPL_ASSERT((is_same< mpl::vector<int, char>, generate_mpl_vector<fusion::vector<int, char> >::type >)); I need generate_fusion_vector and generate_mpl_vector metafunctions. I can write my own metafunctions, but i suspect that they already exist. I generated fusion::map with help result_of::as_map before, so vector generation is the same, but in current boost(trunk, 1.39 also) such error occur: D:\Libraries\boost_trunk\boost/fusion/sequence/intrinsic/size.hpp(56) : error C2903: 'apply' : symbol is neither a class template nor a function template D:\Libraries\boost_trunk\boost/fusion/container/vector/convert.hpp(23) : see reference to class template instantiation 'boost::fusion::result_of::size' being compiled with [ Sequence=boost::mpl::vector ] temp.cpp(71) : see reference to class template instantiation 'boost::fusion::result_of::as_vector' being compiled I don't understand what is going on? -- Regards, Andrey

MUMPS interface
by Markku Karhunen 24 Jun '09

24 Jun '09

Hi all, On the MUMPS (a MUltifrontal Massively Parallel sparse direct Solver) project website they say: "Karl Meerlenberg has developped C++ bindings for MUMPS. They are available in BOOST, the path is boost/numeric/bindings/mumps/mumps_driver.hpp ". Does anybody know anything about this library? The path seems to be nonsense to me, maybe I'm missing something here? Best, Markku

Re: [Boost-users] building boost with unsupported compiler
by McLemon, Sean 24 Jun '09

Yep we really do have a completely different compiler\toolchain from any currently present, with different switches to GCC, different extensions for compiled objects etc. Of course bjam doesn't need to be built for the target architecture :) It's just that while poking around it looked like bjam needed to have some knowledge about the toolchains it was building for and I suspected that the .jam files in the directory I mentioned earlier were a means to do this. Effectively I want to take steps to make our tools one of the "Builtin tools", mentioned in the help here: http://www.boost.org/boost-build2/doc/html/bbv2/reference/tools.html, so our customers can build Boost with our tools without any fuss. - Sean Date: Tue, 23 Jun 2009 19:00:05 +0400 From: Vladimir Prus <vladimir(a)codesourcery.com> Subject: Re: [Boost-users] building boost with unsupported compiler To: boost-users(a)lists.boost.org Message-ID: <h1qqlh$b7t$1(a)ger.gmane.org> Content-Type: text/plain; charset=us-ascii McLemon, Sean wrote: > Hi, > > > > I'm looking to build Boost with a compiler not currently supported, but > I'm struggling to find information on where I should really begin.

I know folks were compiling Boost for arm-linux, in particular, with minor issues. - Volodya

[fusion] BOOST_FUSION_ADAPT_STRUCT private members?
by Stephan Menzel 24 Jun '09

24 Jun '09

Hi there, I'm looking for a way to BOOST_FUSION_ADAPT_STRUCT() private members of a struct. Is this possible? I'd like to parse with spirit2 directly into a struct with getters that should not be bypassed. Cheers, Stephan

[interprocess]Error compiling my program with boost and GCC
by Laurence Chambenois 24 Jun '09

24 Jun '09

Hello, I use boost 1.38. I try to compile my program that includes <boost/thread.hpp> <boost/interprocess/sync/named_recursive_mutex.hpp> I didn't have any problem to compile boost libraries. But when I compile my program, I've got the following error : In file included from /usr/include/boost-1_38/boost/interprocess/detail/move.hpp:21, from /usr/include/boost-1_38/boost/interprocess/shared_memory_object.hpp:18, from /usr/include/boost-1_38/boost/interprocess/sync/named_recursive_mutex.hpp:23, from /home/Dev/Criteria4/WebTools/WebModules/src/Noyau/cemTask.h:27, from /home/Dev/Criteria4/WebTools/WebModules/src/CriEm/cemAppWebSrv.h:28, from /home/Dev/Criteria4/WebTools/WebModules/src/CriEm/cemAppWebSrv.cpp:19: /usr/include/boost-1_38/boost/interprocess/detail/mpl.hpp:64: attention : all member functions in class `boost::interprocess::detail::is_convertible<T, U> ' are private In file included from /usr/include/boost-1_38/boost/interprocess/shared_memory_object.hpp:31, from /usr/include/boost-1_38/boost/interprocess/sync/named_recursive_mutex.hpp:23, from /home/Dev/Criteria4/WebTools/WebModules/src/Noyau/cemTask.h:27, from /home/Dev/Criteria4/WebTools/WebModules/src/CriEm/cemAppWebSrv.h:28, from /home/Dev/Criteria4/WebTools/WebModules/src/CriEm/cemAppWebSrv.cpp:19: */usr/include/sys/mman.h:145: error: type specifier omitted for parameter ` mode_t' /usr/include/sys/mman.h:145: error: erreur d'analyse syntaxique before `)' token* /usr/include/boost-1_38/boost/interprocess/sync/emulation/named_creation_functor.hpp:38: embrouillÚ par les erreurs prÚcÚdentes, abandon make[1]: *** [/home/Dev/Criteria4/WebTools/WebModules/UseIT/bin/objCriemWeb/cemAppWebSrv.o] Erreur 1 I understand that mode_t is an undefined type. But as mman.h is a standard include file, I don't understand why. Can somebody gives me a help ? I surely forget something important but I don't know what. For informations, I use GCC 3.3.3. Thanks for yours answers Laurence

Passing lambda placeholders to functions
by Zachary Turner 24 Jun '09

24 Jun '09

It seems very simple, but it's not compiling. int translate(const std::string& str) { return 0; } //all required using declarations are present but omitted for brevity // options_description options; variables_map values; int i; options.add_options() ("test", value<std::string>()->notifier(var(i) = translate(_1))); I get the following error: 'translate': cannot convert parameter 1 from 'boost::lambda::placeholder1_type' to 'std::string'. No user defined conversion operator available that can perform this conversion, or the operator cannot be called. Is this type of usage unsupported for some reason? If I change the variable declaration and the add_options() call to the following it works fine: std::string s options.add_options() ("test", value<std::string>()->notifier(var(s) = _1));

Boost spirit... classic?
by Space Ship Traveller 24 Jun '09

24 Jun '09

Hi, I'm a bit confused. It seems like all the includes for boost spirit are "classic" i.e. it seems to me I have an old version, but I'm currently using 1.39. I looked on the spirit website and there is no information about the correct way to use the latest version of the spirit framework. The most I found was a post from about a year ago about the "classic" includes. The documentation on the boost website doesn't have any information. Is there some information about this somewhere? What should I be doing to create new parsers? Kind regards, Samuel

[Proto] fatal error C1001: An internal error has occurred in the compiler.
by christophe henry 24 Jun '09

24 Jun '09

Hi all, Here am I already at the 2nd compiler (VC9SP1) crash of the week (not kidding...): fatal error C1001: An internal error has occurred in the compiler. (compiler file 'f:\dd\vctools\compiler\utc\src\p2\p2symtab.c', line 5809) Attached is a test file producing the problem. The crash happens when I add BOOST_PROTO_DEFINE_OPERATORS. Am I doing something wrong? Sadly, this was a workaround to avoid deriving my class from proto::terminal because of a problem (supposedly) created by the address-of operator. Can someone save my day and tell me if there is a way to deactivate this operator for terminals? Concretely, I have: struct Empty: public state<>, proto::terminal<state_tag> Which brings me, here: &::boost::fusion::at_key<State>(xxx) // xxx being a fusion set containing Empty the following problem: 1>f:\projects\MSM2\SM\boost/msm/back/state_machine.hpp(1061) : error C2784: '::boost::enable_if<is_pseudo_exit<StateType>::type,void>::type boost::msm::back::state_machine<Derived,HistoryPolicy,CopyPolicy>::execute_entry(StateType *,const EventType &,FsmType &,boost::msm::back::dummy<__formal>)' : could not deduce template argument for 'StateType *' from 'const boost::proto::exprns_::expr<Tag,Args,Arity>' 1> with 1> [ 1> Derived=`anonymous-namespace'::player_, 1> HistoryPolicy=boost::msm::back::NoHistory, 1> CopyPolicy=boost::msm::back::DeepCopy, 1> __formal=2 1> ] 1> and 1> [ 1> Tag=boost::proto::tag::address_of, 1> Args=boost::proto::argsns_::list1<boost::proto::exprns_::expr<boost::proto::tag::terminal,boost::proto::argsns_::term<boost::msm::front::state_tag>> &>, 1> Arity=1 1> ] I have another workaround but it requires more typing and is quite ugly, so any help would be greatly appreciated.

[program_options] separating long name and short name
by svarneticist 23 Jun '09

23 Jun '09

Hello, I would like to store an option name in a variable and later use it with variables_map. E.g. const char* incl = "include-path"; options_description desc; desc.add_options()(incl, "include path"); variables_map vm; store(parse_command_line(argc, argv, desc), vm); if(vm.count(incl)) { ... } But if I also want to specify a short name const char* incl = "include-path,i"; ... The answer here is always zero: vm.count(incl) Is there a way to add a short name separately? Thank you Mikhail

How to build libboost_thread-vc90-mt-sgd-1_39.lib
by luca regini 23 Jun '09

23 Jun '09

With a complete build of boost (running bjam from the main directory) I cannot find libboost_thread-vc90-mt-sgd-1_39.lib. However the same library is linked automatically when I use the thread library within a program build against the Multi-threaded (/MT) runtime of Visual studio 2008. What should I do? Luca
