Hi all, one single (windows) user in my project community (http://www.soundjack.eu) has the following problem: #ifndef BOOST_THREAD_DEFINES_THREAD_ATTRIBUTES_NATIVE_HANDLE cout << "THREAD IS NOT DEFINED" << endl; #endif This statement is true but only for him – on any other machine (Win, Linux and OSX) is works fine. Does anybody know what he can do in order to fix this issue ? Thanks in advance, best Alex

help with boost::variant, accessing recursive types
by Littlefield, Tyler 29 Sep '16

29 Sep '16

all, I have the following: boost::make_recursive_variant<int, bool, std::string, std::map<std::string, boost::recursive_variant_>>::type node; I'm populating this tree. I'm using libucl because it has a relaxed JSON syntax but I wanted to have a tree-like configuration here. The std::map is a key:value pair obviously. So my questions: How do I get std::maps from this variant? I know boost::get exists, will it just return a pointer to std::map? does setting elements in the map set elements on the variant? I also didn't see any return info for what boost::get returns if the element does not exist. Will it just return null since it does return a T*? Finally, is there a way to see the type of the variant? I don't really care if it's a bool or string, although I would like to place some implicit checks on certain values when they're retrieved. PS: If there's a way to pull this off with boost::property_tree, I would love to know how. I'm looking at using libucl as mentioned before because it provides a nginx-like not really JSON-style configuration syntax. Any tips would be appreciated. HOpefully these questions are clear and make sense. -- Take care, Ty Twitter: @sorressean Web: https://tysdomain.com Pubkey: https://tysdomain.com/files/pubkey.asc

Unable to build boost 1.61 on Solaris 11.3 w/ DevStudio 12.5
by Jon Earle 29 Sep '16

29 Sep '16

Please bear with me as I am not really familiar with Solaris. I have an 11.3 box, where I installed the developer studio 12.5. Following directions at https://blogs.oracle.com/studiocpp/entry/test, I tried to build boost 1.61. It fails horribly! I get as far as: >> create compiler configuration for Studio 12.4 C++03 (using Boost.Config configure) so all the fancy C++11 stuff in Boost is not yet enabled even if we compile with -std=c++11. ] cd libs/config; CXX=CC CXXFLAGS="-std=c++03 -m64" LDFLAGS="-std=c++03 -m64" sh ./configure << which fails. Config.log contains: configure:1959: CC -std=c++03 -m64 -std=c++03 -m64 conftest.cpp >&5 CC: Warning: Option -std=c++03 passed to ld, if ld is invoked, ignored otherwise CC: Warning: Option -std=c++03 passed to ld, if ld is invoked, ignored otherwise ld: fatal: option '-d' has illegal argument '=c++03' ld: fatal: option '-d' has illegal argument '=c++03' Removing "-std=c++03" does allow the configure process to run but not as it was intended. Building with: "./b2 --user-config=user-config.jam address-model=64 -j12 --disable-icu" gives me a lot of errors, such as those below. Below my problem description, I've pasted the build errors I noticed until I broke the build. What is the proper sequence to build boost 1.61 on Solaris? Many thanks for any help!

Insertion/Use of boost::multi_index - new thread

Hi, When I try to create a object of this, typedef boost::multi_index_container< ClassX*, //mapped value boost::multi_index::indexed_by< //list of indices boost::multi_index::hashed_unique< boost::multi_index::const_mem_fun<ParentClassOfX, Key1, &ParentClassOfX::getKey1> //hashed index by unique Key1 >, boost::multi_index::hashed_unique< boost::multi_index::const_mem_fun<ParentClassOfX, Vs64, &ParentClassOfX::getKey2> //hashed index by unique Key1 > > >ClassXMultiKeyIndexed; like, ClassXMultiKeyIndexed sample; and insert a pointer like this, ClassX *a; ClassXMultiKeyIndexed sample; //a is not NULL and is filled up before the below insert sample.insert(a); This is the compilation error, it compiles fine if "sample.insert(a)" is commented out.

local_time.hpp gives ... boost errors

Hi, I could narrow the place where boost errors appears. Using VS2010 (with 'show includes') on a Win7 machine. Boost is installed in C:\utilitaires\boost\boost15\boost_1_50_0\boost and this directory name has been replaced by - underneath (so it's version 1.50 !) When I write #pragma message (" avant boost/date_time/local_time/local_time.hpp") #include "boost/date_time/local_time/local_time.hpp" I get all these error messages : avant

ambiguous overload for operator>> error when using lexical_cast with qvm::vec
by kique G 28 Sep '16

28 Sep '16

Hi, I am trying to use lexical_cast to convert from strings to qvm vectors, but I keep getting an ambiguous operator>> error. I have overloaded the >> operator for istreams and that seems to be working fine when I use it to read from a istringstream. In a lexical_cast, though, I get the "ambiguous overload for operator>>" error. I have tried declaring my operator>> overload inside the std and boost::qvm namespaces to check if it was something related to ADL, but I keep getting the same error. The thing is the other candidates do not seem to make a lot of sense to me. Could somebody please tell me what I am doing wrong? Thanks in advance, Enrique Garcia This is a minimal example (I am building gcc/boost from the last versions on their repositories): #include <iostream> #include <boost/qvm/vec.hpp> #include <boost/lexical_cast.hpp> std::ostream& operator<<(std::ostream& out, boost::qvm::vec<float, 3> const& v) { out << "(" << v.a[0] << "," << v.a[1] << "," << v.a[2] << ")"; } std::istream& operator>>(std::istream& in, boost::qvm::vec<float, 3>& v) { char c; return in >> c >> v.a[0] >> c >> v.a[1] >> c >> v.a[2] >> c; } int main() { boost::qvm::vec<float, 3> vect { 1.0f, 2.0f, 3.0f }; std::cout << vect << std::endl; // This code works just fine. (4.0,5.0,6.0) is printed std::istringstream istream("(4.0,5.0,6.0"); istream >> vect; std::cout << vect << std::endl; // This code generates an ambiguous overload for operator>> error (see below) vect = boost::lexical_cast<boost::qvm::vec<float, 3>>("(1.0,2.0,3.0)"); std::cout << vect << std::endl; return 0; } This is the error I am getting from gcc: In file included from /usr/local/include/boost/config.hpp:61:0, from /usr/local/include/boost/static_assert.hpp:17, from /usr/local/include/boost/qvm/static_assert.hpp:7, from /usr/local/include/boost/qvm/vec.hpp:11, from /home/kique/Documents/Bitflow2x/source/main.cpp:57: /usr/local/include/boost/type_traits/detail/has_binary_operator.hpp: In instantiation of 'const bool boost::detail::has_right_shift_impl::operator_exists<std::basic_istream<char>, boost::qvm::vec<float, 3> >::value': /usr/local/include/boost/type_traits/detail/has_binary_operator.hpp:179:4: required from 'const bool boost::detail::has_right_shift_impl::trait_impl1<std::basic_istream<char>, boost::qvm::vec<float, 3>, boost::detail::has_right_shift_impl::dont_care, false>::value' /usr/local/include/boost/type_traits/detail/has_binary_operator.hpp:208:4: required from 'const bool boost::detail::has_right_shift_impl::trait_impl<std::basic_istream<char>, boost::qvm::vec<float, 3>, boost::detail::has_right_shift_impl::dont_care>::value' /usr/local/include/boost/type_traits/detail/has_binary_operator.hpp:216:8: required from 'struct boost::has_right_shift<std::basic_istream<char>, boost::qvm::vec<float, 3>, boost::detail::has_right_shift_impl::dont_care>' /usr/local/include/boost/lexical_cast/detail/converter_lexical.hpp:241:21: required from 'struct boost::detail::deduce_target_char_impl<boost::detail::deduce_character_type_later<boost::qvm::vec<float, 3> > >' /usr/local/include/boost/lexical_cast/detail/converter_lexical.hpp:270:89: required from 'struct boost::detail::deduce_target_char<boost::qvm::vec<float, 3> >' /usr/local/include/boost/lexical_cast/detail/converter_lexical.hpp:407:92: required from 'struct boost::detail::lexical_cast_stream_traits<const char*, boost::qvm::vec<float, 3> >' /usr/local/include/boost/lexical_cast/detail/converter_lexical.hpp:468:15: required from 'struct boost::detail::lexical_converter_impl<boost::qvm::vec<float, 3>, const char*>' /usr/local/include/boost/lexical_cast/try_lexical_convert.hpp:196:44: required from 'bool boost::conversion::detail::try_lexical_convert(const Source&, Target&) [with Target = boost::qvm::vec<float, 3>;

[boost][heap] Which heap to use.
by degski 27 Sep '16

27 Sep '16

Hi All, I seem to remember reading about this [the subject of this post] in the docs, but I don't seem to be able to find it [that page] now. What criteria should I use to choose a specific Boost.Heap implementation (skew, fibonacci etc), from the ones provided by the Boost.Heap library? Thanks in advance and have a good day, degski

newbie !!
by MAURICE Jean 27 Sep '16

Hi, This is my second 'account' to this mailing list. In fact I am a freelance who works for a company that works for another company and when I am somewhere I can't have access to the 'elsewhere' outlook. I am an old C++ (and FORTRAN and Visual Foxpro) programmer. But I am new to boost, windows (MFC) and Visual Studio 2010. My challenge is to 'upgrade' a huge app (250 k lines of code) both Windows and Linux from boost 1.3.x (and stingray and .....) to boost 1.50 and win 7 ... Boost 1.50 is the last version our customer can use because of its 'private' version of Debian. I am first dealing with windows. When I compile the solution, I get a lot of errors and I would like you give me the first steps to do. Here is an example about file ...\boost\boost15\boost_1_50_0\boost/mpl/list/aux_/preprocessed/plain/list20.hpp list20.hpp(157): error C2143: syntax error : missing ',' before 'string' list20.hpp(163): error C2974: 'boost::mpl::list19' : invalid template argument for 'T18', type expected list20.hpp(144) : see declaration of 'boost::mpl::list19' list20.hpp(167) : see reference to class template instantiation 'boost::mpl::list20<T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14,T15,T16,T17,T18,__formal>' being compiled list20.hpp(164): error C3203: 'list19' : unspecialized class template can't be used as a template argument for template parameter 'Next', expected a real type list20.hpp(164): error C2955: 'boost::mpl::list19' : use of class template requires template argument list list20.hpp(144) : see declaration of 'boost::mpl::list19' list20.hpp(165): error C2955: 'boost::mpl::l_item' : use of class template requires template argument list So if you can explain me what is wrong (I mean I am astonished (?) to find a syntax error and I think I must not modify the file so the error may come from elsewhere ...) TIA Jean

[fiber] High CPU usage when fiber round robin sheduler is idle
by lin li 26 Sep '16

26 Sep '16

Hi, guys. I have a problem with Boost fiber in 1.62 beta 2. My machine is a 4 core machine with 64bit ubuntu 14.04 installed. In my program, I created 4 kernel threads each of which uses the round robin fiber scheduler. One thread 1, I created one fiber that read data from a socket in a blocking manner. Once it got some data, it writes the data into a blocking fiber channel. For the rest thread kernel threads, I created 5 fibers for each of them. They all read (in a blocking manner) data from the same channel. My problem is when no data is sent to the socket, and the system is idling, I can see very high CPU usage on three cores. I profiled the code, it seems to me that the kernel threads keep calling fiber scheduler to sleep then wake up again. I suspect that the time interval for the function suspend_until() may be too short. If that is the case, then how can I increase it?
