[type_traits] is_list_constructible regression failures
by Lorenzo Caminiti 13 Mar '18

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

Is there any specific template that I should follow for the proposal or I can make it my own way?

Re: [boost] [gsoc18] Mentor Request for uBLAS (prefer support for tensors)

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
by Mohd Faisal 11 Mar '18

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.

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

Hey there, My name is Christos (Chris for short) and I would love to work with you via the GSoC program this summer. I am sending this mail because I am in a need for some instructions on how to find a mentor and a project (at first). Can anyone help me with that? Also is there any potential mentor here? Any info helps. Thanks a lot in advance!

[gsoc18] Regarding Boost uBLAS Google Summer of Code 2018
by Varun Mehrishi 09 Mar '18

09 Mar '18

Hi, I am Varun Mehrishi, a third year engineering student from Manipal University Jaipur (MUJ), India. I am currently pursuing Bachelors of Technology in Computer Science and Engineering. I am most comfortable with C++(STL) and Python, and also follow the new and experimental features introduced in the new standards with additional help of cppcon and BoostCon. I also have interests in Data Science, Machine Learning. I wish to participate and contribute to Boost.uBLAS. I've read the project idea and description from the suggested GSoC project proposals. I am really interested in working on the project "Project 1 : Add statistics and machine learning functions" which is focused on extending Boost.uBLAS functionality towards statistics/ML. I have implemented a basic template version of the mentioned Programming Competency Test (basic-matrix-lib <https://github.com/varunmehrishi/basic-matrix-lib>) and used C++14 generic lambdas wherever necessary. Your feedback and suggestions will be extremely valuable as they will help me improve my implementation and add more functionality. Looking forward to your guidance -- With warm regards, Varun Mehrishi GSoC 2018 Aspirant
