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

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.

I'm trying to build Boost on OpenVMS I64 8.2 and it fails in building jam. Has anyone succeeded in building on 8.2? If so, can you provide the cc and linker options you used? Thanks. P

[serialization] reference to a vector of shared pointers of objects with non-default constructible templated class
by codeur＠altern.org 29 Nov '05

29 Nov '05

Hello, I have a non-default templated class (let's call it Klass), serialized throw a pointer, so I redefined save_construct_data and load_construct_data for the type Klass<double>. One of the member of my class has the following type: typedef boost::shared_ptr< Point3d<T> >PointPtr; vector< PointPtr >& stuff; Point3d is another templated class. T could be for instance, double. Point3d is track_selectivly, Klass is track_selectivly and serialized by another class with a pointer. In save_construct_data when I do : ar << t->stuff; I've got the following problem : boost-1_33/boost/archive/detail/oserializer.hpp:566: error: incomplete type `boost::STATIC_ASSERTION_FAILURE<false>' does not have member `value' Perhaps I didn't place the good track attribute. Does someone have an idea ? Thanks in advance!

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

29 Nov '05

I'm just getting started with trying to serialize some Python and C++ objects that are glued together with Boost.Python. Would it be fair to say that this link <<http://mail.python.org/pipermail/c++-sig/2004-September/008044.html>> represents the "standard" approach to this? Thanks, MD

Good day everyone, i'm using the boost::date_time::posix_time libarary in my application.
