[statechart] LNK2001 revisited
by Noah Roberts 15 Aug '10

15 Aug '10

Found a related post dated Jul 2007: http://old.nabble.com/-statechart-LNK2001-Error-on-VC-8.0- td11748021.html Attempted use of /Gm of course did not fix the problem (not sure why the OP did that to begin with as it's pretty much incompatible with building for release). Information in this thread lead to an *apparent* sollution: http://thread.gmane.org/gmane.comp.lib.boost.user/23065 But I'm not really impressed by that sollution and the commentary on it lead me to believe that I should not need it since I'm not making a library. The issue appears when I set the /Yu flag (use precompiled headers) in Visual Studio 2010. (10.0.30319.1) Without this flag active the program eventually compiles and links without issue. With the flag active I get exactly the same error as the OP though this is not regarding the tutorial code, which I have not tested. I also have to set /Zm200 or the build doesn't even get started (something about the space not being large enough for my 50 line header). The precompiled header is NOT including anything in boost statechart. The only boost related includes are: #define BOOST_PARAMETER_MAX_ARITY 20 #include <boost/cast.hpp> #include <boost/bind.hpp> #include <boost/format.hpp> #include <boost/parameter.hpp> #include <boost/signals2.hpp> #include <boost/lexical_cast.hpp> #include <boost/optional.hpp> And through other includes Boost.Units. I am not building a library nor is any of the statechart code in a library, though the build process does say it creates a .lib with the same name as the .exe I ask for but that also happens in debug. The whole thing is in a header that is included by the .cpp file that generates the .obj that causes the linker error. Again, debug builds work perfectly well with the same flags that cause the problem in release. Boost version is 1.42 Would like to know what's going on, how to correctly fix it, etc... -- http://crazyeddiecpp.blogspot.com/

boost error serialization

[smart_ptr]intrusive_ptr suggestion
by gast128 15 Aug '10

15 Aug '10

Hello all, probably not a good time to post during the stress of 1.44 release. We use boost a lot and also the intrusive_ptr to wrap ref counted objects. However the intuitive behavior gives memory leaks. For example use a ref counted object KFoo: intrusive_ptr<IFoo> ptr(new KFoo); // mleak, KFoo is extra ref counted ptr.reset(new KFoo) //mleak ptr = intrusive_ptr<IFoo>(new KFoo, false); //ok, but Spartan way of writing Above examples are all in contrast with the syntax of shared_ptr's, in which one could write it in above way without leaking. Although the constructor of intrusive_ptr has an extra argument, its default is set on true. Wouldn't it be a nice suggestion to create a function like make_intrusive, so that one could write: ptr = make_intrusive<KFoo>(); It seems so basic that there must be a hidden caveat somewhere...

[tuple][mpl][fusion] How to "prune" or "collapse" a tuple?
by AJG 14 Aug '10

14 Aug '10

Hi all, > [added this line to make gmane happy.] I'm looking for a way to remove "empty" values from a tuple. In other words, say I have a tuple T: tuple<E, int, E, double, E, char, E> T; // where E can be either null_type, or mpl::void_, etc. I'd like for it to collapse into: tuple<int, double, char> T2; Now, the reason I say "values" is because I found a way to do just that, but only for the types, which you'll find below. However, I can't figure out how to then *construct* the collapsed tuple given the original tuple (and its values.) Specifically, it's the `???' below that I'm missing. Thanks! // Collapse code: template <typename Sequence> struct tuple_from_sequence : mpl::reverse_fold < Sequence , tuples::null_type , tuples::cons<mpl::_2, mpl::_1> > {}; template <typename T0, typename T1, typename T2, typename T3, typename T4, typename T5, typename T6, typename T7, typename T8, typename T9> struct collapse <tuple<T0, T1, T2, T3, T4, T5, T6, T7, T8, T9> > { typedef tuple<T0, T1, T2, T3, T4, T5, T6, T7, T8, T9> original; typedef mpl::list<T0, T1, T2, T3, T4, T5, T6, T7, T8, T9> sequence; typedef typename mpl::remove<sequence, tuples::null_type>::type removed; typedef typename tuple_from_sequence<removed>::type type; static type construct(original const& t) { // return ???; } };

Problem compile error
by Luigi Seregni 14 Aug '10

14 Aug '10

Hello, I'm currently developing a windows ce application and I need to use some regular expression. My colleagues suggest me to use boost regex library, but I've experienced some troubles during installation procedures. I'm currently working on Visual Studio 9.0, so I've download the libraries' installer files from this site BoostPro computing. I've followed all the instructions stated in this document: http://www.boost.org/doc/libs/1_43_0/more/getting_started/windows.html#id33, but when I try to compile the example at point 6 (link your program to a boost library) I've obtained this error from compiler: 1>C:\Program Files\boost\boost_1_42\boost/regex/v4/regex_workaround.hpp(46) : fatal error C1083: Cannot open include file: 'locale': No such file or directory I've tried to find a solution but I still haven't found a solution! Can you please help me? Best regards, -- Luigi Seregni

Unicode option in program_options
by John Dlugosz 14 Aug '10

14 Aug '10

Here is the problematic part: namespace po = boost::program_options; po::options_description common_options("common options"); common_options.add_options() ("help", po::bool_switch(&helpflag), "produce help message") ("dir", po::value<std::wstring>()->notifier(&datadir_set), "the directory") ; I get a huge speil of error output, concluding with see reference to class template instantiation 'boost::program_options::typed_value<T,charT>' being compiled with [ T=std::wstring, charT=char ] Reading "Unicode Support" in the docs, it sounds like design decisions rather than any how-to, but the beginning is clear: it is possible to mix wide and narrow options, and aggregating options from libraries or parsing different input sources should work. So why does it barf at the use of a wide-char string as a desired option? I expect that the wchar_t* form of the parser will pass that unchanged to this option, and the char* form should convert.

[preprocessor] How to generate list of statically-sized array elements
by Kenny Riddile 14 Aug '10

14 Aug '10

Say I have an array: ArgumentType arguments[ argumentCount ]; where argumentCount is a size_t template parameter. I would like to generate, at compile time, a comma-delimited list of the form: arguments[0], arguments[1], arguments[2], ...arguments[argumentCount-1] Can this be accomplished using Boost.Preprocessor or by some other method?

Anybody know what's the status on the portable binary archive? I just got the "critical error: basic_string::resize" when trying to open a binary file on amd64 that was saved on intel32. The same was reported a while back, and it seemed a portable binary archive was to be included soon. This was with boost 1.34 while I got this with boost 1.40.

[graph] getting from vertex item to finding related elements
by Noah Roberts 13 Aug '10

13 Aug '10

I figure there HAS to be some way to do what I need but I can't think of it at the moment. Currently I have a couple of objects called "edge_description" and "vertex_description" that are the properties of the vertex and edges within a graph. What I want to be able to do is retrieve an edge_description from a vertex_description. Graph declaration looks like so: typedef boost::adjacency_list < boost::listS , boost::listS , boost::bidirectionalS , vertex_description , edge_description > system_graph_t; The only way I can think of to do this is to make the graph and the graph::vertex_descriptor reference members of the vertex_description object and manually keep those synchronized (serialization being the main issue). I'm disliking that plan. Is there a method of construction a graph that would get me what I want? So that when I have a pointer or reference to an element in the graph I can fetch connected elements? -- http://crazyeddiecpp.blogspot.com/
