License questions
by Julian D. 25 Mar '17

25 Mar '17

I am making a confidential commercial closed-source program, and Boost's libraries seem useful for me. I can't tell if the Boost license allows me to include it in closed-source. Would anybody know?

That appears to be the definition of what license they wanted, not the actual license. The license body makes it unclear if I can use this in a closed-source commercial environment On Thu, Mar 23, 2017 at 3:51 PM, <boost-users-request(a)lists.boost.org> wrote: > > Message: 5 > Date: Thu, 23 Mar 2017 17:54:04 +0100 > From: Mateusz Loskot <mateusz(a)loskot.net> > To: boost-users(a)lists.boost.org > Subject: Re: [Boost-users] License questions > Message-ID: > <CABUeae_a-cNCdw00fYN4Gyb_a7Gk_QOo7cARXNo3Lh8eXAAVtQ@ > mail.gmail.com> > Content-Type: text/plain; charset=UTF-8 > > On 23 March 2017 at 17:38, Julian D. via Boost-users > <boost-users(a)lists.boost.org> wrote: > > I am making a confidential commercial closed-source program, and Boost's > > libraries seem useful for me.

[format] warning...warning...warning
by Arnaud RICHARD 24 Mar '17

24 Mar '17

Hello, I'm a complete Boost newbie. I've been told very often that boost is the way to go for serious C++ coding, and I was not surprised to see such emphasis on the home page: "We aim to establish "existing practice" and provide reference implementations so that Boost libraries are suitable for eventual standardization" So when I used the format library on my existing (non-trivial) project and first compiled... I was very very surprised to get my neat compilation console flooded with hundreds of warnings ! I acknowledge I activate many many warnings: CXXFLAGS+=-Wall -Wextra -Wcast-qual -Wctor-dtor-privacy -Wdisabled-optimization \ -Wformat=2 -Winit-self -Wlogical-op -Wmissing-include-dirs \ -Wnoexcept -Woverloaded-virtual -Wredundant-decls -Wshadow \ -Wsign-conversion -Wsign-promo -Wstrict-null-sentinel -Wstrict-overflow=5 \ -Wswitch-default -Wundef -Wunused The warnings were as trivial as (for example): ../ext/boost/boost/type_traits/is_default_constructible.hpp:16:22: warning: "BOOST_GCC_VERSION_WORKAROUND_GUARD" is not defined [-Wundef] #if BOOST_WORKAROUND(BOOST_GCC_VERSION, < 40700) ../ext/boost/boost/format/parsing.hpp:435:67: warning: conversion to 'std::vector<boost::io::detail::format_item<char, std::char_traits<char>, std::allocator<char> >, std::allocator<boost::io::detail::format_item<char, std::char_traits<char>, std::allocator<char> > > >::size_type {aka unsigned int}' from 'int' may change the sign of the result [-Wsign-conversion] string_type & piece = (cur_item==0) ? prefix_ : items_[cur_item-1].appendix_; I understand they are only warning and the code is functionally correct and standard-wise correct. Personally when I face such false warnings in my code, I change the code to remove the warning so that if a warning does make sense, I can notice it. I thought a reference implementation would be written with such policy. There's no way I'm gonna read each of the hundreds of messages to understand if it is a mistake in my source code or a "shortcut" in boost library. So this is my first user experience. Not impressed at all. Boost will not be my reference.

Hi, I need to run boost asio client socket connections to remote servers via a remote proxy server, the remote proxy server has a public IP address, but none of remote servers have public IP addresses. Appreciate any clues or samples. Thank you.

[TypeErasure] efficiency problem
by Mikhail Strelnikov 24 Mar '17

24 Mar '17

Hello! In following code TypeErasure creates two copies of s, while Boost.Any creates no copies at all. any x{ s{} }; any y{ std::move(x) }; any z; z = std::move(y); There is move constructor for type_erasure::any, but it does allocate memory and calls copy constructor for s. Why? And why there is no move assignment operator in type_erasure::any? Thanks. Full source: https://wandbox.org/permlink/iHs5a0bjzXsBtpwC

[Iterator] zip iterator with std::tuple or std::pair
by Matthias Wohlgemuth 23 Mar '17

23 Mar '17

Hello, as far as I understand the zip_iterator is compatible also with STL tuple and pair. However, when I try to create a zip_iterator with std::pair it fails to compile. Here, a simple test code: #include <vector> #include <utility> #include <boost/iterator/zip_iterator.hpp> int main () { std::vector<int> v(4); boost::make_zip_iterator(std::make_pair(v.begin(), v.begin())); return 0; } compiled with gcc 4.9.2 and boost 1.62 returns me (tested also with 1.63): In file included from /software/boost-1.62/include/boost/iterator/zip_iterator.hpp:26:0, from test.cpp:3: /software/boost-1.62/include/boost/mpl/at.hpp: In instantiation of ‘struct boost::mpl::at_c<std::pair<__gnu_cxx::__normal_iterator<int*, std::vector<int> >, __gnu_cxx::__normal_iterator<int*, std::vector<int> > >, 0l>’: /software/boost-1.62/include/boost/iterator/zip_iterator.hpp:180:17: required from ‘struct boost::iterators::detail::zip_iterator_base<std::pair<__gnu_cxx::__normal_iterator<int*, std::vector<int> >, __gnu_cxx::__normal_iterator<int*, std::vector<int> > > >’ /software/boost-1.62/include/boost/iterator/zip_iterator.hpp:237:9: required from ‘class boost::iterators::zip_iterator<std::pair<__gnu_cxx::__normal_iterator<int*, std::vector<int> >, __gnu_cxx::__normal_iterator<int*, std::vector<int> > > >’ test.cpp:8:64: required from here /software/boost-1.62/include/boost/mpl/at.hpp:42:8: error: no class template named ‘apply’ in ‘struct boost::mpl::at_impl<boost::mpl::non_sequence_tag>’ struct at_c ^ In file included from test.cpp:3:0: /software/boost-1.62/include/boost/iterator/zip_iterator.hpp: In instantiation of ‘struct boost::iterators::detail::zip_iterator_base<std::pair<__gnu_cxx::__normal_iterator<int*, std::vector<int> >, __gnu_cxx::__normal_iterator<int*, std::vector<int> > > >’: /software/boost-1.62/include/boost/iterator/zip_iterator.hpp:237:9: required from ‘class boost::iterators::zip_iterator<std::pair<__gnu_cxx::__normal_iterator<int*, std::vector<int> >, __gnu_cxx::__normal_iterator<int*, std::vector<int> > > >’ test.cpp:8:64: required from here /software/boost-1.62/include/boost/iterator/zip_iterator.hpp:180:17: error: no type named ‘type’ in ‘struct boost::mpl::at_c<std::pair<__gnu_cxx::__normal_iterator<int*, std::vector<int> >, __gnu_cxx::__normal_iterator<int*, std::vector<int> > >, 0l>’ >::type difference_type; ^ /software/boost-1.62/include/boost/iterator/zip_iterator.hpp:198:11: error: no type named ‘type’ in ‘struct boost::mpl::at_c<std::pair<__gnu_cxx::__normal_iterator<int*, std::vector<int> >, __gnu_cxx::__normal_iterator<int*, std::vector<int> > >, 0l>’ > type; I get a similar results for std::tuple compiled c++11 enabled gcc. I did not find any solution, except a 3 year old patch, which is said to be applied to the boost::iterator library. Any suggestions? Best regards, Matthias

Is Boost API 32Bit only?
by Andrej Georgi 19 Mar '17

19 Mar '17

I try to build Boost on MSYS2-64Bit which includes 64-Bit headers of windows. Boost is calling a 32-Bit variant of windows API even when Boost is configured to build 64-Bit. There is a 64Bit pre build variant of Boost on sourceforge. That seems to run only in visual studio? Does it use a 32 Bit API as well? Is there any reason for this design? I personaly prefer any variant of GCC over visual studio due to time consuming experiences with visual studio. Kind regards Andrej
