Hi, I'm trying to build master with oneAPI 2023.1.0's icpx. So far I am mostly getting warnings for unknown/unsupported options like: icpx: warning: -Wl,-rpath,/data/spack/opt/spack/linux-centos7-x86_64/gcc-12.2.0/intel-oneapi-mkl-2023.1.0-x6dxpakvvn4sntkmbzqvtjdndc3g5ttn/mkl/2023.1.0/lib/intel64: 'linker' input unused [-Wunused-command-line-argument] intel-linux.compile.c++ bin.v2/libs/log/build/intel-linux-2023.1.0/release/cxxstd-17-iso/threading-multi/visibility-hidden/setup/matches_relation_factory.o icpx: command line warning #10430: Unsupported command line options encountered These options as listed are not supported. For more information, use '-qnextgen-diag'. option list: -ip -wd177,780,2196,1782,193,304,981,1418,411,734,279 Is oneAPI supported ? the following page: https://www.intel.com/content/www/us/en/developer/articles/technical/buildi… only mention 1.75 and 1.78 Thanks Alain

[boost.async] Seeking Endorsement
by Klemens Morgenstern 28 Jul '23

28 Jul '23

Dear fellow Boost developers, I am seeking endorsement for my C++20 async coroutine library boost.async. It provides coroutine primitives & utilities that are easy to use and intuitive, to anyone who has seen python's asyncio or javascripts async/await APIs before. It simplifies using asio and increases compile times significantly by encouraging the usage of translations units. The features include: - coroutine types (eager, lazy, generators) - built-in cancellation - synchronization of multiple coroutines (select, gather, join) - channels - with (an async scope akin to python's with expression) - asio integration, i.e. completion tokens I think this kind of library is much needed in boost and the wider C++ community. code: https://github.com/klemens-morgenstern/async docs: https://klemens.dev/async/

Request to merge a fix to Boost.Core
by Peter Dimov 26 Jul '23

26 Jul '23

May I please merge the following fix https://github.com/boostorg/core/commit/c7134904e27237dbbb81ba28f0f23fc365b… to address issue https://github.com/boostorg/core/issues/150 ? I can't verify that the fix actually works, but it doesn't affect non-Android platforms, so can't make things any worse.

Can I get permission to merge a few small bug fixes plus docs fixes? https://github.com/boostorg/outcome/commits/develop 1. Changes just before the beta window breaks build on C++ 14 in certain corner cases, fixed. 2. Experimental Outcome Boost result did not compile due to changes to status code by LEWG, fixed. 3. Docs fixes also due to the LEWG renaming breaking docs examples. 4. Failure to compile Experimental Outcome on FreeBSD fixed. Niall

boost::normal_distribution<>(boost::mt19937) changed behavior from 1.60 to 1.80
by Foelsche, Peter 18 Jul '23

18 Jul '23

Dear All, I'm not certain if the behavior I'm seeing is expected or a problem. I'm getting different series of numbers from the two different boost versions in question. When running a diff on the output I'm getting numbers inserted in one series or the other and then the two series become identical again. Below is the source. I'm using the following series of commands: g++ -std=c++14 test.cpp -g -DNDEBUG -fwhole-program -I/mnt/share/boost/boost-1.80/include -o 180 g++ -std=c++14 test.cpp -g -DNDEBUG -fwhole-program -o 160 ./180 16384 2078781393 1 > 180.txt ./160 16384 2078781393 1 > 160.txt diff 160.txt 180.txt |more The first difference is at line 284. The next at 364, 1783, 2685. Peter PS. g++ (GCC) 5.3.0 PPS. The source #include <boost/random.hpp> #include <boost/version.hpp> //#include <boost/random/variate_generator.hpp> #include <boost/random/mersenne_twister.hpp> #include <boost/random/normal_distribution.hpp> #include <boost/random/uniform_int_distribution.hpp> #include <limits> #include <iostream> int main(int, char**argv) { std::cout << BOOST_LIB_VERSION << std::endl; const auto bOld = std::atoi(argv[3]) != 0; boost::mt19937 sGenerator; sGenerator.seed(std::atoi(argv[2])); //boost::random::uniform_int_distribution<> sDist(0, std::numeric_limits<int>::max()); boost::normal_distribution<> sDist(0.0, 1.0); boost::variate_generator<boost::mt19937, boost::normal_distribution<> > sGen(sGenerator, sDist); for (int i = 0, iMax = std::atoi(argv[1]); i < iMax; ++i) if (bOld) std::cout << sDist(sGenerator) << std::endl; else std::cout << sGen() << std::endl; }
