[gsoc18] sharing of proposal
by vardhan gupta 15 Mar '18

15 Mar '18

Hi, I have shared the 1st draft of my proposal for "adding multicore and GPU computations to uBLAS" through the gsoc portal, but haven't yet gotten any feedback on it. Do I need to share it again on the mailing list too? Regards, Vardhan Gupta

[gsoc18] Student proposal reviewing (Internal process)
by madhur4127 14 Mar '18

14 Mar '18

Hi Boost Community, As per Submission template <https://svn.boost.org/trac10/wiki/SoCSubmissionTemplate> a candidate is required to show competency in C++ and must be "genuinely" interested in the project and also in open-source community. Judging of competency is straight forward, but how can interest be judged? Considering myself as example who had just got in serious open source projects(Sophomore Undergraduate). My coding ablilities <https://github.com/madhur4127/Programming-Competency-Test> are not at expert level but I am improving and learning myself while my university teaches knapsack greedy and automaton. Doesn't this gives an idea of interest in open source of a candidate or am I being a sophomore is a disadvantage with respect to other post graduate candidates? I know boost requires serious level work and it has world's most craftiest libraries but does Boost prefer experienced candidates or take chances with candidates genuinely interested in development and are moderately skilled? As per the division rules "A student must be able to write in C++". Regards, Madhur gsoc18 aspirant [Boost.Intrusive] -- Sent from: http://boost.2283326.n4.nabble.com/Boost-Dev-f2600599.html

[gsoc18] Boost.Detour & Mentor Search
by Michael Kiros 14 Mar '18

14 Mar '18

Hello, I'm a C++ developer and have been developing in C++ for over 6 years now in my personal time. I wanted to accomplish two things with this post: 1. Propose the idea of boost::detour 2. Find a mentor in the process Boost.Detour is not something new that I'd like to implement but a concept in programming that I have been using for a very long time now and would love to have it easily accessible with the inclusion of a simple <boost/detour.hpp>. The idea is to have function hooking easily accessible to everyone using C++. Though it may seem like a niche feature, function hooking is more commonly used than most people think (e.g. modifying binaries after compilation for feature addition, reverse engineering proprietary software). It's a beautiful concept when you see it working. In the process I need a mentor to guide me through the process of putting down my ideas to paper and implementing them according to the standards that Boost holds. This includes replacing components from my library with Boost concepts (e.g. boost::process). I'm also a student at Texas Tech University studying Computer Science. Can't wait to hear from someone. Michael

[type_traits] is_list_constructible regression failures

Hello all, I noticed the following failure in Boost.TypeTraits regression tests on GCC 4.6 C++11. Any idea why this is failing? http://www.boost.org/development/tests/master/developer/type_traits.html Test output: igaztanaga-master-gcc-4.6c++11 - type_traits - cxx14_aliases_test / gcc-4.6c+ Rev cb62bbf20f4a0000ee6f16835b0c2dc92edea8cd / Sun, 11 Mar 2018 03:16:04 +0000 Compile [2018-03-11 10:15:18 UTC]: fail "C:/Programs/mingw-builds/x32-4.6.4-posix-dwarf-rev0/mingw32/bin/gcc-4.6.bat" -pipe -fmax-errors=1 -std=c++0x -m32 -O0 -fno-inline -Wall -pedantic -Werror -march=i686 -Wextra -Wno-bool-operation -Wno-int-in-bool-context -Wno-uninitialized -DBOOST_ALL_NO_LIB=1 -I".." -I"..\libs\type_traits\test\libs\tt2\light\include" -c -o "c:\boost\master\results\boost\bin.v2\libs\type_traits\test\cxx14_aliases_test.test\gcc-4.6c+\dbg\dbg-symbl-off\cxx14_aliases_test.o" "..\libs\type_traits\test\cxx14_aliases_test.cpp" In file included from ../boost/type_traits.hpp:110:0, from ..\libs\type_traits\test\cxx14_aliases_test.cpp:10: ../boost/type_traits/is_list_constructible.hpp:36:61: error: expected class-name before 'decltype' compilation terminated due to -fmax-errors=1. I am asking because a couple of Boost.Contract tests that #include <boost/type_traits.hpp> fail with the same Boost.TypeTraits error on this compiler. Thanks. --Lorenzo
