The problem about shorthest path computation
by liu jianfei 01 Dec '05

01 Dec '05

Hi, all Recently, I faced a big problem when I'm using the boost function of shorthest path computing including dijkstra_shortest_paths and johnson_all_pairs_shortest_paths. My projectet was that I extracted all the surface voxels of a volume as the vertexs of the graph, and 26-connection between them as a edge. Hence, I got a large sparse graph which composed of 12768 vertexs and around 86000 edges. In the next stage, I implemented the dijkstra_shortest_paths computation for each vertex. However, it succeded in some points and failed in other points. If I changed the weight of each edge into 1, all points worked. If I used other weights for different edges, then problem poped up. Also, some points worked for this special weight, and failed for others. I think the shortest path algorithm should be unrelated with the weight assignment. Initially, I think something was wrong in my graph buliding. But when I wrote the shorthest path algorithm by myself and all points worked, I felt there may be a bug in dijkstra_shortest_paths class. If someone else faces the same problem, feel free to tell me. If not, I'm willing to paste my graph code in spite of its complexity. Thanks Regards!

Compilation difference between intel 9.0 and msvc 7.1 regarding const
by Chris Goller 30 Nov '05

30 Nov '05

I have code that will compile using msvc 7.1 but will not under intel 9.0. Here is some simplified code to illustrate my problem: using namespace boost; using namespace std; typedef array<int, 2> array_type; array_type a; a[0] = 0; a[1] = 1; vector<array_type> v; v.push_back(a); vector<int> h; for_each(v.begin(), v.end(), mem_fun_ref(&array_type::front)); This compiles and runs using msvc 7.1, but intel 9.0 errors with the following: error: more than one instance of overloaded function "mem_fun_ref" matches the argument list: function template "std::mem_fun_ref(_Result (_Ty::*)() const)" function template "std::mem_fun_ref(_Result (_Ty::*)())" argument types are: (<unknown-type>) Here are the two definitions of front for boost::array: reference front() { return elems[0]; } const_reference front() const { return elems[0]; } If I'm reading the error correctly, this means that the intel compiler doesn't know if I want to use the const or non-const version of front. Does anyone know anything about this? Is this the forwarding problem? Is a function wrapper around front a good solution? What are the solutions? Thanks, Chris

[Boost.Iostream] missing BOOST_IOSTREAMS_DECL in mapped_file.hpp
by Marc Viala 30 Nov '05

30 Nov '05

Hi, I'm not really sure but I think there are some missing export declarations in the "mapped_file.hpp" of Boost.Iostream. The missing declarations are for the struct mapped_file_sink and the class mapped_file. I've joined the corrected "mapped_file.hpp" Could you confirm these observations? Marc Viala

Re: [Boost-users] Overload problem with bind
by Kerner, Jacques 30 Nov '05

Okay, just to nail it down : - boost::bind does not generate the error and you don't need to cast the function pointer whereas - boost::lambda::bind needs you to explicitely cast the function pointer Thank you!

Yes. This works: boost::lambda::bind( static_cast<float& (Position::*)() > (&Position::GetX), boost::ref(myPos)); Also, boost::bind doesn't seem to have this problem. There was a recent thread about this feature, by Peter Dimov and John Maddock, IIRC.

Hi, I'm not really sure but I think there are some missing export declaration in the "parser.hpp" of Boost.date_time. The missing declarations is for function "special_value_from_string()" I've joined the corrected "parser.hpp" Could you confirm these observations?

How to compile with a conventional Makefile in BOOST
by Ace Bluedust 30 Nov '05

30 Nov '05

Hi, I would like to know if someone could show me how to compile and build with a conventional Makefile (linux-gnu-gcc) for the BOOST GRAPH LIBRARY. I'm not sure of which lib files to link and what are the needed flags. I have to do by Makefile because I also use another library other than BOOST. Thanks.

[format] negative 0?
by Alain Cormier 30 Nov '05

30 Nov '05

I use boost 1.32 with VS 6.0 (sp5) on Windows2000. If I try this : int anIntValue(-0); std::cout << anIntValue << '\n';\ I get : 0 And, if I try this : boost::format formatTest("My test : %0.0f \n"); double theValue(-0.0002); std::string theString = boost::io::str(formatTest % theValue); I get : "My test : -0" Is it the right behavior? I was expecting the same result (simply a 0). Maybe I am wrong... Thank you for any advise / suggestion. Alain

how to declare a reference to a boost shared pointer?
by eric 30 Nov '05

30 Nov '05

Can I declare a pure virtual member function which accepts as input a boost shared pointer to an object of a base class, such that - clients of the function can pass in as input a boost shared pointer to an object of a derived class - concrete implementations of the function can redirect the pointer to a new object of an (even more) derived class ? Consider the following class hierarchy in the problem domain: class Serializable {}; class Foo : public Serializable {}; class Bar : public Foo {}; Here is the pure virtual member function I would like to declare: class Serializer { public: virtual void serializeObject(boost::shared_ptr < Serializable > &) = 0; } And the relevant subset of one of its concrete implementations: class XmlReader : public Serializer { virtual void serializeObject(boost::shared_ptr < Serializable > &p) { p = boost::shared_ptr < Serializable > (new Bar()); } } The client would call the function like this: boost::shared_ptr < Foo > foo; Serializer *s = new XmlReader(); s->serializeObject(foo); The above code doesn't compile, the error message from VC6 is main.cpp(72) : error C2664: 'serializeObject' : cannot convert parameter 1 from 'class boost::shared_ptr<class Foo>' to 'class boost::shared_ptr<class Serializable> &' The best solution I have found so far is to declare the function like this: class XmlReader : public Serializer { virtual boost::shared_ptr < Serializable > serializeObject() { boost::shared_ptr < Serializable > ret = boost::shared_ptr < Serializable > (new Bar()); return ret; } } And call it like this: foo = boost::dynamic_pointer_cast< Foo >(s->serializeObject()); But that's not ideal for my purposes, I would prefer to have a function which modifies its inputs and returns void. I can't implement the function as a template because I need it to be virtual. Any assistance gratefully received. Regards, Eric

Boost.python serialization
by Drumheller, Michael 29 Nov '05

29 Nov '05

Thank you for the help. I have seen that link (the one you supplied) before, but I posted my question because that link in particular does not mention the words "Boost.Serialization" or "Archive" at all. I suppose what I was really getting at, and was probably not very clear about (sorry :| ) was whether the specific approach (by N. Becker) of using a stringstream wrapped with a boost::archive::binary_oarchive is a standard idiom. (Basically, I would have thought that "python pickle boost::archive" would be a million-hit Google query, but it's only about a dozen. I find that weird. Do people just not serialize their C++ extensions very often?) Thanks again. I really appreciate the help.
