Dear all, my name is Georgios Samaras, a Masters student from NKUA, Greece. I am interested in the distance predicates <https://svn.boost.org/trac/boost/wiki/SoC2017#PROJECT1.Filteringofcomparedi….> of Boost Geometry, but I am flexible. I am attaching my CV in case anyone is interested. Here is my GitHub <https://github.com/gsamaras>, which demonstrates that I have experience in C++. Good luck with all your projects, Georgios Samaras

Issue Tracker for Boost organization?
by Olaf van der Spek 16 Mar '17

Hi, Do we have an issue tracker for Boost 'organization' itself? I know we've got mailing lists and the steering committee but it's hard to track issues like that. -- Olaf

[gsoc17] boost.uBLAS

Hi My name is Leandro, I'm a CS student at the University of Buenos Aires, and I'm interested in the uBLAS projects. I've already done the competency test and I was wondering who I should talk/send it to and who could be a possible mentor. Thanks

Libc++ failures on linux
by Tom Kent 16 Mar '17

16 Mar '17

So I tried to add my first linux regression runner using libc++ with clang, and I'm seeing the following error saying it can't find <cstddef>: http://www.boost.org/development/tests/develop/developer/output/teeks99-02-… "clang++-3.9" -c -x c++ -Wno-c99-extensions -std=c++1z -stdlib=libc++ -O0 -g -fno-inline -Wall -g -m64 -DBOOST_ALL_NO_LIB=1 -DBOOST_CHRONO_STATIC_LINK=1 -DBOOST_CHRONO_THREAD_DISABLED -DBOOST_SYSTEM_NO_DEPRECATED -DBOOST_SYSTEM_STATIC_LINK=1 -DBOOST_TEST_NO_AUTO_LINK=1 -DBOOST_TIMER_STATIC_LINK=1 -I".." -o "/var/boost/run/results/boost/bin.v2/libs/accumulators/test/count.test/clang-linux-3.9~c++1z~lc/debug/link-static/count.o" "../libs/accumulators/test/count.cpp" In file included from ../libs/accumulators/test/count.cpp:6: In file included from ../boost/test/unit_test.hpp:18: In file included from ../boost/test/test_tools.hpp:17: In file included from ../boost/config.hpp:44: ../boost/config/select_stdlib_config.hpp:18:12: fatal error: 'cstddef' file not found # include <cstddef> ^ 1 error generated. However when I try to compile the following program on the same docker image (teeks99/boost-build:clang-3.9) // basic.cpp #include <cstddef> int main(int argc, char* argv[]) { size_t three = 3; return three; } with: $ clang++-3.9 -stdlib=libc++ -std=c++1z basic.cpp It works fine $ ./a.out $ echo $? 3 I can build this sample file fine with the whole command line shown above, so it doesn't seem to be one of the other options conflicting. Any thoughts on why boost code wouldn't be able to find this but some basic stuff would? One relevant detail, I'm building with clang 3.9, however the libc++ version that I'm using (ubuntu default) is the one that shipped with clang 3.7. That shouldn't preclude including a file! I also found a couple old threads with the same error, but never any good resolution. http://lists.boost.org/boost-testing/2012/07/7075.php http://lists.boost.org/boost-users/2012/11/76659.php Tom

[config] msvc-14.1 and C++14 constexpr
by John Maddock 13 Mar '17

13 Mar '17

So.... MSVC-14.1 (2017) sort of supports C++14 constexpr. However, it is also prone to internal compiler errors, and currently does not compile config_test.cpp unless we set BOOST_NO_CXX14_CONSTEXPR. Does anyone have a view on which way this macro should be set? Thanks, John. --- This email has been checked for viruses by AVG. http://www.avg.com

Re: [boost] [gsoc17] Project1: Static map: Can I implement the competency test in g++-7?
by Vic Luo 13 Mar '17

13 Mar '17

Hi, During the implementation of my static_map, I recently encountered a problem: how to deal with string types? For example: constexpr auto cmap_str = make_static_map({ {"abc", 1}, {"bcd", 2} }); static_assert(cmap_str["abc"] == 1, "test"); In my implementation, KeyType requires 1. constexpr operator==, which is not provided by const char * 2. constexpr hash(const KeyType&). Since there is no such thing in standard library, I have to implement some in this project. Currently I would like to use string_view, since it looks like a general solution for compile-time string with lots of constexpr functions, but I don't know which of the following designs looks better: Design A: template<typename KeyType, typename MappedType, typename EqualOp = StaticEqualOp<KeyType>, typename HashOp = StaticHashOp<KeyType>> class static_map; // StaticEqualOp: Specialize StaticEqualOp for those KeyTypes that // can construct string_view and use operator== of string_view, // otherwise we simply use operator== of KeyType // StaticHashOp: size_t operator()(const string_view&, const string_view&) // for types that can construct string_view Design B: We don't specialize any StaticEqualOp for const char*. Instead, make_static_map({{"abc", 1}}) returns static_map<string_view, int> instead of static_map<const char *, int>. Which one is better? Or is there any more feasible design?

[gsoc17] Project Static map : Clarifications and Competency test
by Pasindu Kanchana 13 Mar '17

13 Mar '17

Hi I am Pasindu Kanchana from Sri Lanka, studying at the University of Moratuwa as a final year undergraduate(4th year).I have worked as a developer intern for past 6 months for an exchange related company focusing c++ and have used boost memory mapped_file , tokenizer and filesystem. It would be really helpful if i get answers for the following 3 questions. A)Although the requested key is not in range ,still the code should compile?(without any error throwing and halting compilation) B)The solution to the problem should prove that compile time initiation of the map is confirmed(constexpr should definitely compile at the compile time not remain to the run time).would it be enough to practically proving this for different compilers under c++14 to approve as a solution? C)Should I take the competency test? Thank you.
