Hello, I am new to Boost. I was looking for socket classes that are a component of Boost. Somehow, I couldn't find any. Are there "boost sockets"? Thanks in advance, Jason

Re: [Boost-users] Problem with unit test BOOST_AUTO_TEST_MAIN
by Sakharuk, Vlad (GMI Development) 19 Jul '07

Yes, if I remove all lib it does run successfully. I identified that tests run from TinyXML lib (opensource). I have to link with other libraries because the code I have to test depends on them. I am just creating tast case to narrow down the problem. I will look in 1.34.o but probably I could not. I will apriceate any solution how to disable particular testing suit (from TinyXML). I could not physically remove those test from the lib.

[Regex] Link error with G++ 3.3.2, but Okay with 3.4.5
by Ambarish Mitra 19 Jul '07

Hi all, I have the following code to validate a given url using boost::regex. The code is failing linking with g++ 3.3.2, but is building with 3.4.5 Any workaround, or pointer to help to build in 3.3.2? I am on boost 1.32.

[Matrix iterators] Beginner problem
by Regis Behmo 19 Jul '07

19 Jul '07

Hello everyone, I don't understand how to use iterators with matrices; how can I scan all the elements of a matrix? The only thing I have managed to do until now is to read/write the elements of the first row or the first column: ublas::matrix<int> M(3,3); int i = 0; for( ublas::matrix<int>::iterator1 Mit1 = M.begin1(); Mit1 != M.end1(); Mit1++ ) { *Mit1 = i; i++; } Are there such things as row iterators, column iterators, or iterators ocver all the elements of the matrix? Thanks Régis B.

[program_options] add_options method hangs on Linux
by Farberov, Inga 19 Jul '07

19 Jul '07

Hi, I have a piece of code that runs both on Windows and Linux. I am using program_options library to read a settings file. This seems to work fine on windows, but on Linux the same code hangs when I call add_options method. I am using Boost 1.34 on both machines. Any suggestions on what may be causing this problem are greatly appreciated. Inga

boost::mpi + boost::shared_ptr
by Andras Joo 19 Jul '07

19 Jul '07

Dear All, I have encountered a problem I cannot go through regarding boost::mpi and shared_ptr. Please consider the following code: class Foo { friend class boost::serialization::access; template<class Archive> void serialize(Archive &ar, const unsigned int version) { //... } }; //... mpi::communicator world; boost::shared_ptr<Foo> pFoo; if (world.rank() == 0) pFoo = boost::shared_ptr<Foo>(new Foo); mpi::broadcast(world, pFoo, 0); //...

boost::mpi + serialization of polimorphic pointers
by Andras Joo 19 Jul '07

19 Jul '07

Dear All, I'm facing the following problem. I have the following class hierarchy: AbstractBase <--- AbstractDerived <---- ConcreteDerived I managed to make the serialization of AbstractBase using text and binary archives (text_[i/o]archive, binary_[i/o]archive), tested, and works fine. However when AbstractBase pointers are sent with MPI functions a runtime exception occurs: /usr/include/boost-1_35/boost/archive/detail/oserializer.hpp:413: static void boost::archive::detail::save_pointer_type<Archive, TPtr>::polymorphic<T>::save(Archive&, const T&, const boost::archive::detail::basic_pointer_oserializer*) [with T = AbstractBase, Archive = boost::mpi::packed_oarchive, TPtr = AbstractBase*]: Assertion `__null != bpos_ptr' failed. I appreciate any help. Thank you, and have a nice weekend. Andras ____________________________________________________________________________________ Moody friends. Drama queens. Your life?

scoped_ptr, shared_ptr and pimpl
by Noah Roberts 19 Jul '07

19 Jul '07

I have an object that uses scoped_ptr to point to it's impl...an incomplete type forward declared in the header and implemented in the cpp file. This object *does have a user defined destructor*! This user defined destructor is defined after the opaque type has been fully defined in the same cpp file. In another cpp file I have a function that lives in the same namespace as the object in question, which creates a shared_ptr to this object. I'm getting the "undefined type" error in checked_delete for the impl object. I've run into this problem before but it was because I did not have a user defined destructor for the outer object...now I do. I even created a blank destructor for the impl, something I've never had to do before. What gives? Any ideas where to look for the problem? My simplest program that exhibits the problem doesn't exhibit the problem...I find this frustrating.
