run-time integer log2
by Tim Blechmann 15 Jul '10

15 Jul '10

hi all, i am aware, that boost provides a compile-time integer log2 function. but what is the best way to compile an integer log2 at run-time? thanks, tim -- tim(a)klingt.org http://tim.klingt.org Silence is only frightening to people who are compulsively verbalizing. William S. Burroughs

Bug in VC++ using templates and or my error
by Edward Diener 15 Jul '10

15 Jul '10

I realize this question may not belong here, but since the code in question uses Boost, I will ask here first and hope I may be forgiven for doing so. The following code does not fail with a compile time message from BOOST_MPL_ASSERT but it seems as if it should, with both VC9 and VC10: ---------------------------------------------------------------------- #include "stdafx.h" #include <boost/config.hpp> #include <boost/mpl/assert.hpp> struct test_default { }; namespace test_template1 { template < class T1, class P1_1, class P1_2 > char test(typename T1::template AMemberTemplate<P1_1,P1_2> *); template < class T1, class P1_1, class P1_2 > char (&test(...))[2]; } template < class T, class P1 = test_default, class P2 = test_default > struct test_template { typedef test_template type; BOOST_STATIC_CONSTANT(bool, value=sizeof(test_template1::test<T,P1,P2>(0))==1); }; namespace test_template2 { template < class T1, class P1_1 > char test(typename T1::template AMemberTemplate<P1_1> *); template < class T1, class P1_1 > char (&test(...))[2]; } template < class T, class P1 > struct test_template < T, P1, test_default > { typedef test_template type; BOOST_STATIC_CONSTANT(bool, value=sizeof(test_template2::test<T,P1>(0))==1); }; struct TType { template <class X> struct AMemberTemplate { }; }; void AFunction() { BOOST_MPL_ASSERT(( test_template<TType> )); } ------------------------------------------------------------------ It appears that the specialization of the 'test_template' template is being chosen instead of the main template itself but I do not see why this should be so. Is this my error or an actual bug in VC9 and VC10. If it is a VC bug, does Boost currently have a way to workaround it ?

Boost.Ranges 2.0 algorithms accepting a const reference
by Stefano Peluchetti 14 Jul '10

14 Jul '10

Hi, the Boost.Ranges (v 1.43) documentation suggests that for each algorithm there is a version accepting a reference to a range and a version accepting a const reference to a range (which in my case would be useful for the "non-const reference to temporary object problem" when dealing for example with a boost::iterator_range<std::vector<double>::iterator> range). However the code (take for instance the reverse algorithm) does not seems to include the const reference version. Am I missing something, is the documentation incorrect, or it has been decided against the const reference version? Thank you in advance for your help. Stefano

Are these variables really needed? They theoretically create a word per compilation scope. A cleaner alternative would be to just call the function where needed. If you really need to define global variables in a header only library, you can define static members of a template class. It's a fancy trick (not sure if it has a name). Perhaps there are portablity issues with it. Chris

[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
