[Range] Definition of a range for gsl_vector
by Karsten Ahnert 14 Jul '10

14 Jul '10

Hi, I want to define a range for gsl_vector's. I have tried many versions according to the manual but none is working. Maybe someone here could help me. This is what I do, or least what I think is most promising (the full code can be found in the attachment): namespace boost { template<> struct range_iterator< gsl_vector* > { typedef gsl_vector_iterator type; }; template<> struct range_iterator< const gsl_vector* > { typedef const_gsl_vector_iterator type; }; range_iterator< gsl_vector* >::type begin( gsl_vector* &x ) { return gsl_vector_iterator( x ); } range_iterator< const gsl_vector* >::type begin( const gsl_vector* &x ) { return const_gsl_vector_iterator( x ); } range_iterator< gsl_vector* >::type end( gsl_vector* &x ) { return end_iterator( x ); } range_iterator< const gsl_vector* >::type end( const gsl_vector* &x ) { return end_iterator( x ); } } // namespace boost The iterators for gsl_vector are defined separately in the attachment. If I now try to use the range via typedef boost::range_iterator< gsl_vector* > gsl_iter_type; gsl_iter_type::type i3 = boost::begin( vec ); gsl_iter_type::type i4 = boost::end( vec ); I get the following compile errors: /home/karsten/boost/boost_1_43_0/boost/mpl/eval_if.hpp: In Instantiation of ‘boost::mpl::eval_if_c<true, boost::range_const_iterator<gsl_vector*>, boost::range_mutable_iterator<gsl_vector* const> >’: /home/karsten/boost/boost_1_43_0/boost/range/iterator.hpp:63: instantiated from ‘boost::range_iterator<gsl_vector* const>’ ../src/test_gsl_iterator.cpp:23: instantiated from here /home/karsten/boost/boost_1_43_0/boost/mpl/eval_if.hpp:60: error: no type named ‘type’ in ‘struct boost::range_const_iterator<gsl_vector*>’ make: *** [src/test_gsl_iterator.o] Error 1 This is somehow strange, since begin() and end() are not used from my definition, but from the original defintions in the Range library. Can someone help me with this? What am I doing wrong? Best regards, Karsten

[Serialization]Runtime error: Assertion `! detail::singleton_wrapper<T>::m_is_destroyed' failed
by Moch Ramis 14 Jul '10

14 Jul '10

Hello While i was trying to run the folowing code: #include "FaceBase.h" int main() { FaceBase< EigMemberProps<int,std::string> > F(std::string("facebase.archive")); return 0; } I get the error message : /.../boost/serialization/singleton.hpp:124: static T& boost::serialization::singleton<T>::get_instance() [with T = boost::archive::detail::iserializer<boost::archive::text_iarchive, std::vector<EigMemberProps<int, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<EigMemberProps<int, std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > > >]: Assertion `! detail::singleton_wrapper<T>::m_is_destroyed' failed. But the strangest it that this happen before the first instruction (the FaceBase constructor is not call). However, if i retrive the text_oarchive and text_iarchive calls in constructor and destructors, it works fine.... do you have any clue about this error ? Thanks.

[Serialization] Can't Serialize vectors of user-defined classes
by Moch Ramis 14 Jul '10

14 Jul '10

hi all. I recently tried to execute this very simple example: #include <iostream> #include <boost/archive/text_oarchive.hpp> #include <boost/archive/text_iarchive.hpp> #include <boost/serialization/vector.hpp> #include <fstream> class A { public: A(){} private: //Serialization tasks friend class boost::serialization::access; template<class Archive> void serialize(Archive & , const unsigned int ) { } }; int main() { std::vector<A> eig; std::cout <<eig.size()<<std::endl; std::ofstream of("file.txt"); { boost::archive::text_oarchive oa(of); oa << eig; } of.close(); std::ifstream ifs("file.txt"); { boost::archive::text_iarchive ia(ifs); ia >> eig; } std::cout <<eig.size()<<std::endl; return 0; } On my compiler (gcc 4.4.1), it compile fine but there is a runtime error when the application start: /.../boost/serialization/singleton.hpp:124: static T& boost::serialization::singleton<T>::get_instance() [with T = boost::archive::detail::iserializer<boost::archive::text_iarchive, std::vector<EigMemberProps<int, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<EigMemberProps<int, std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > > >]: Assertion `! detail::singleton_wrapper<T>::m_is_destroyed' failed. Curiously, the comportment of the gcc 4.1.2 of codepad is not the same: http://codepad.org/sEK2fLua Curiously, this works fine on my compiler when i olny serialize A but not with the codepad compiler: http://codepad.org/j3wlsWDv Do you have any clue about this problem ? Thanks

boost C++ load data from file
by Jack Bryan 14 Jul '10

14 Jul '10

Dear All, I need to load data (24 X 28 X 40) from 24 X 28 files into a datastructure so that my program can usethem to do operations. Each file has 40 data items, which are floating numbers. I hope that the data structure can be indexed by item name not only by integer. For example, for 24 states in USA, each state's power consumption is POWC in year Y. I hope that the data structure indexing is like this datastructure[newYork][year][powerconsumption] My question is : (1) how to load the data from 24 x 28 files by boost C++? It is boring to type file's name one by one in program. Is there an alternative to load the data by indexing the file names ? for example, for (filename = name1; filename < filenum ; filename++){ load data from filename; store loaded data in the datastructure.} (2) how to index the item of the datastructure by boost C++ ? Any help is appreciated. Jack July 11 2010 _________________________________________________________________ Hotmail is redefining busy with tools for the New Busy.

MPI::get_content with string member

Hi all, I am trying to separate structure from content and send a vector of strings. Without the separation it works fine, I do receive the data on workers.

list all drives
by Lloyd 13 Jul '10

13 Jul '10

Hi, I am programming on a widows system. Is it possible to list all drives available in a system with boost::filesystem library or any other boost library? I have gone through boost::filesystem documentation, but could not find any :( Thanks a lot, Lloyd ______________________________________ Scanned and protected by Email scanner

boost how to map between string and operation
by Jack Bryan 13 Jul '10

13 Jul '10

Dear All: I need to bind some strings with some operations boost map. For example, if inputString == "prepareDataVector1" dataVectorRegionRef = prepareDataVector1; loadDataVector.push_back("prepareDataVector1"); else inputString == "prepareDataVector2" dataVectorRegionRef = prepareDataVector2; loadDataVector.push_back("prepareDataVector2");else ... so on I have checked boost lib, map can do mapping of two class, I need to do mapping between string and operations. Any help is appreciated. Jack July 13 2010 _________________________________________________________________ Hotmail has tools for the New Busy.

boost::interprocess, allocators and containers of containers
by Matthew Stump 13 Jul '10

13 Jul '10

I'm attempting to create a buffered queue backed by a memory mapped file. The main data structure is a boost::interprocess::list of boost::interprocess::shared_ptr< Buffer<T> >. Buffer<T> is a struct that has two members: an interprocess_upgradable_mutex and a interprocess::deque. When I attempt to push an item into the deque contained by the struct I get a SIGSEGV in rbtree_best_fit::priv_mark_as_free_block() at line 1153 when using boost 1.43. I'm passing the allocator to the constructor of the deque as instructed in the documentation and I'm using all types which should be boost::interprocess safe. I've spent a couple hours on this one item and I'm not making any progress; I was wondering if someone could please lend me a hand. Source excerpt and backtrace: https://gist.github.com/ff7912d4582d68b825c3 Thanks, Matt Stump P.S. Other helpful criticism of my usage or advice on boost::interprocess would be greatly appreciated.

apply std::pow to vector or matrix
by Max S. Kaznady 13 Jul '10

13 Jul '10

I followed the UBLAS extensions here: http://www.crystalclearsoftware.com/cgi-bin/boost_wiki/wiki.pl?Examples_-_H… and I figured out how to extend functions like "exp" and "log" to act on a vector. But, those are functions of one argument. What I want is to be able to apply a function with one fixed argument, like std::pow, to a vector for some exponent exp, so I would like the code to look like: vector<double> v( 100 ); double exponent = 2.1; // some exponent value // ... fill v ... std::cout << apply_to_all( v, functor::my_pow<double>(exponent) ) << std::endl; std::cout << apply_to_all<functor::my_pow<double>(exponent) >( v ) << std::endl; OR std::cout << apply_to_all( v, functor::my_pow<double>() , exponent) << std::endl; How can I do this? I tried overloading apply_to_all and writing constructor code, but it didn't work because the return type of the apply function is static. P.S. I tried posting this to ublas lists, but got a message saying that my e-mail address is not registered. I guess that list is only for developers. Thanks, Max
