[Boost::asio] Problem using the same io_service with many sockets
by María Victoria Rocha 03 Oct '16

03 Oct '16

Hi all, I have defined an io_service that is used by two sockets, one of them uses tcp, and the other udp. When the callback of this async_read_some is called socket.async_read_some(boost::asio::buffer(readBuffer), boost::bind(&RequestHandler::onRead, shared_from_this(), boost::asio::placeholders::error, boost::asio::placeholders::bytes_transferred)); A udp socket is created with the same io_service and an async_receive_from is called. On the callback of this read operation I try to write to the tcp socket but it captures an exception with message: "unknown exception". When this happens, the client that is listening to the tcp socket, receives "End of file" error. I resolved this problem with an io_service per socket but I would like to use the same io_service. Someone has any idea why this happens? Thanks! Victoria

[Thread] Thread library in boost 1.62 broken with g++ 4.6.3 and -std=c++0x
by Andreas Wehrmann 03 Oct '16

03 Oct '16

Hello folks, I've just wanted to try out the new release and noticed that the Thread library was not building. Assuming this code: #include <boost/thread.hpp> int main( void ) { return 0; } When compiled with -std=c++0x the compilation fails with: In file included from ./boost/boost_1_62_0/boost/exception/detail/exception_ptr.hpp:20:0, from ./boost/boost_1_62_0/boost/exception_ptr.hpp:9, from ./boost/boost_1_62_0/boost/thread/exceptional_ptr.hpp:10, from ./boost/boost_1_62_0/boost/thread/future.hpp:25, from ./boost/boost_1_62_0/boost/thread.hpp:24, from test.cpp:2: ./boost/boost_1_62_0/boost/exception/info.hpp: In instantiation of ‘boost::error_info<boost::tag_original_exception_type, const std::type_info*>’: ./boost/boost_1_62_0/boost/exception/detail/exception_ptr.hpp:95:32: instantiated from here ./boost/boost_1_62_0/boost/exception/info.hpp:66:5: error: ‘class boost::error_info<boost::tag_original_exception_type, const std::type_info*>’ has no member named ‘value_’ ./boost/boost_1_62_0/boost/container/detail/pair.hpp:85:30: warning: ‘boost::container::piecewise_construct’ defined but not used [-Wunused-variable] ./boost/boost_1_62_0/boost/system/error_code.hpp:221:36: warning: ‘boost::system::posix_category’ defined but not used [-Wunused-variable] ./boost/boost_1_62_0/boost/system/error_code.hpp:222:36: warning: ‘boost::system::errno_ecat’ defined but not used [-Wunused-variable] ./boost/boost_1_62_0/boost/system/error_code.hpp:223:36: warning: ‘boost::system::native_ecat’ defined but not used [-Wunused-variable] Compilation works if I don't use -std=c++0x. The exact compiler version is "g++ (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3". I'm aware that g++ 4.6.3 is not among the compilers tested for C++11, but it is for pre-Cpp11; I'm wondering if there is a reason for that which I might not be aware of (any known problems?). Best regards, Andreas

thread no defined - issue
by Alexander Carôt 29 Sep '16

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

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
