Hi All, Recently we upgraded to Boost 1.82.0. We compiled the boost as : ./bootstrap.sh --with-libraries=filesystem,system,program_options,iostreams,log,regex,stacktrace,thread --without-icu When we tried to use the regex library and build Avro product we are getting following error: Boost/boost_1_82_0/include/boost/regex/v4/cpp_regex_traits.hpp:1117: undefined reference to `boost::scoped_static_mutex_lock::scoped_static_mutex_lock(boost::static_mutex&, bool)' Please can you help us in addressing the issue. Thanks and Regards, Prabhakar

Hi, I have a code something like this: TcpConnection::pointer my_conn = GetConn(req); tcp::socket& my_socket = my_conn->getSocket(); tcp::resolver my_resolver(my_socket.get_executor()); Is it possible to check if the my_socket is ipv4 socket or ipv6 socket?

by Kacvinsky, Tom 12 May '23

12 May '23

Hi, I am trying to track down with version of RapidXml is used in Boost 1.78.0. I don't have a problem with the RapidXml license attribution, but I do need to know the specific version of it that is used in Boost for our attribution purposes (copyright year and version). >From what I can see from a git blame, RapidXml was added to Boost around 2007 by the author of RapidXml (Marcin). Does anyone have idea which version is used in Boost? Thanks, Tom

Re: [boost] charconv for C++11

I didn't bother to compare the from_chars scenario (as MSVC doesn't use a highly optimized algorithm there; investigating Eisel-Lemire is on our todo list). > > Hope this helps, > STL > Stephan, Thank you for this. I can add benchmarks for Lemire’s algorithm vs. the current MSVC STL from_chars to see if it’s worth pursuing for your team. Matt

Gavin, Hexfloats are useful for comparison of numerical accuracy. We use them in the Boost.Math unit tests when outputting ULP distances. https://github.com/boostorg/math/blob/develop/test/math_unit_test.hpp#L136 Matt
