[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

Hi Karl, you're exactly the kind of people I want to see in GSOC: student with passion for C++ and some already implemented library. Your competency test is good. Best now is to work on the proposal and send it to us directly (no need to go through the main mailing-list from now on).

[gsoc18] uBLAS competency test
by Arun Ramachandran 11 Mar '18

11 Mar '18

Hello, I'm Arun, a final year computer science undergrad. I'm interested in working on project 1 of the uBLAS library (adding statistics and machine learning functions). I have experience with developing in C++ from working on Code Character (https://github.com/delta/codecharacter-simulator) an online AI programming challenge that some fellow students and I hosted. Since this is an application, I've taken the competency test for uBLAS and have implemented a small matrix library using expression templates along with some unit tests and benchmarks. The repo is currently private, so if a mentor shares their GitHub handle I can add them as a collaborator for reviewing it. Thank you, Arun Ramachandran

[gsoc18] Request for Guidance

11 Mar '18

Hello, my name is Mohd Faisal. I want to work on Boost.uBLAS: linear algebra and matrix computations. Is there a specific reason that only the listed algorithms have to be implemented. Because there are many good ML algorithms that can also be implemented like SVM.

[gsoc18] how to share a competency test
by vardhan gupta 11 Mar '18

11 Mar '18

Hi, My name is Vardhan Gupta. I am a 2nd year undergraduate student from IIT Kanpur. I am interested in working on project #3 of Boost.uBLAS on adding multicore and gpu computations to uBLAS. I have created a private repository of it's competency test on gitlab. Now, I am having trouble in sharing the repository with the mentors since I do not have their email address. how do I share it/find their e-mail address? Thank you, Yours sincerely; Vardhan Gupta
