14 Apr '21

The second release candidates for the 1.76.0 release are now available at: <https://boostorg.jfrog.io/artifactory/main/release/1.76.0/source/ <https://dl.bintray.com/boostorg/release/1.76.0/source/>> The SHA256 checksums are as follows: 7bd7ddceec1a1dfdcbdb3e609b60d01739c38390a5f956385a12f3122049f0ca boost_1_76_0_rc2.tar.gz 0fd43bb53580ca54afc7221683dfe8c6e3855b351cd6dce53b1a24a7d7fbeedd boost_1_76_0_rc2.zip 88782714f8701b6965f3fce087a66a1262601dd5ccd5b2e5305021beb53042a1 boost_1_76_0_rc2.7z f0397ba6e982c4450f27bf32a2a83292aba035b827a5623a14636ea583318c41 boost_1_76_0_rc2.tar.bz2 Changes from RC1: * A missing include was added to a Boost.Regex header. This fixes compilation on gcc 11. As always, the release managers would appreciate it if you download the candidate of your choice and give building it a try. Please report both success and failure, and anything else that is noteworthy. -- The Release managers

by Abhishek Kujur 13 Apr '21

13 Apr '21

Greetings, My name is Abhishek Kujur, I am CSE student at Kalinga Institute of Technology. I have used c++ for like 6 years and I have understanding of C++ Stl, object orientation and template metaprogramming. I would love to be selected at GSOC 2021 by contributing to C++'s well known library, Boost Library. I would be interested in feedback and suggestions. The link to my proposal is: https://docs.google.com/document/d/1NnrBhA4Hu0JYwjSSQJgCTlgYZaYl2FrVinp6h-Z…

I added the boost root directory to my workspace, it didn't work. I have also installed the boost using bootstrap.bat but it still doesn't work.

[gsoc2021]Proposal: Image Processing Algorithms
by ansh grover 13 Apr '21

13 Apr '21

------------------------------ Hi, I am Ansh Grover, a GSoC applicant. I am interested in contributing to the Boost C++ library on the project "*Generic Image Library. I have been coding in C++ for over 6 months, with no prior experience working with Boost libraries. But I am interested in start working with boost libraries and I am willing to put effort into this project by proposing to work for over 30+ hours per week. I have read the problem statement and under GIL there's a project 2 about implementing image processing algorithms and in that list, I would like to work on implementing the k-means clustering algorithm. It would be very helpful if you can guide me through this project. Honestly, I don't expect to be selected for the project with my experience as I am aware of how much work and experience is required, I am just applying with a positive attitude. I am open to any suggestions and I shall proceed with the task upon your acknowledgment. Regards, Ansh Grover

I will be uploading my GSoC 2021 proposal today
by Sidhaant Gupta 13 Apr '21

13 Apr '21

I have been working on my proposal for a week now, but didn't draft it for review yet as I was making it on MS Word and wasn't aware of the review feature on the official GSoC application portal. Kindly pardon me if it falls short of your expectations but rest assured that I will be in touch with all of you from now on. So please do not end the judgement on the proposal and give me a chance to prove my mettle in the coming month before finalising the selections. Kind regards, Sidhaant Gupta

[gsoc21] - Provide quad-double precision for Boost.Multiprecision
by Γιάννης Γονιδέλης 13 Apr '21

13 Apr '21

Hello, My name is Giannis Gonidelis. I am an Electrical & Computer Engineering student from Greece and a regular open-source contributor on HPX developed by STE||AR Group. The past year I have been working on trying to adapt the HPX Parallel Algorithms to C++20 by providing the interface dictated by Ranges-TS (by Niebler). HPX, being a C++ Standards library for Concurrency and Parallelization, has its roots on Boost and widely adopts template meta-programming (our project leader is also the founder of Boost.Spirit). I recognize that I might kick in a little late for a GSoC application, but before sharing my proposal, I would like to know if you plan on mentoring the project about providing the "Quad-Double Backend Type". If so, I would be glad to share my initial thoughts on the project with the mentor, along with my Programming competency test script, in order to submit a cohesive and thorough proposal. Please inform me on the project availability. Regards, Giannis Gonidelis GitHub: gonidelis<https://github.com/gonidelis>

select_stdlib_config.hpp including <version> vs <VERSION> on OS X
by Allen Sanderson 12 Apr '21

12 Apr '21

Hello, A casual boost user and abuser here. Some specifics on my OS OS X Big Sur 11.2 Xcode 12.4 Compiler clang : Apple land version 12.0.0 Boost 1.73 - forward When select_stdlib_config.hpp is included it gets to this initial code to include <version> ... #if defined(__cplusplus) && defined(__has_include) # if __has_include(<version>) // It should be safe to include `<version>` when it is present without checking // the actual C++ language version as it consists solely of macro definitions. // [version.syn] p1: The header <version> supplies implementation-dependent // information about the C++ standard library (e.g., version number and release date). # include <version> ... The issue is that many projects (gnuplot, builtbot, and others) have a VERSION file in their top level src directory. On a traditional Linux system the case sensitivity would make sure the right file is included. However, many/most OS X file systems are case insensitive. As such, the project's VERSION file gets included instead. And does not compile. I have no solution to the issue other than I renamed our project’s VERSION file for the time being. However, I wanted to raise the issue as I noticed it when moving to 1.75 and backtracked out that it was a recent changed starting with boost 1.73 Cheers, Allen Sanderson SCI Institute University of Utah

A new home for Boost releases
by Marshall Clow 12 Apr '21

12 Apr '21

We’ve been using BinTray to host our releases for a few years, and it’s worked well for us However, JFrog is shutting down BinTray soon (at the end of this month). We have moved all the releases that were hosted on BinTray over to JFrog Artifactory. They are at https://boostorg.jfrog.io/artifactory/main/release <https://boostorg.jfrog.io/artifactory/main/release> For example, instead of: https://dl.bintray.com/boostorg/release/1.74.0/source/boost_1_74_0.tar.gz <https://dl.bintray.com/boostorg/release/1.74.0/source/boost_1_74_0.tar.gz> You should now use: https://boostorg.jfrog.io/artifactory/main/release/1.74.0/source/boost_1_74… <https://boostorg.jfrog.io/artifactory/main/release/1.74.0/source/boost_1_74…> I’ll be updating the web site soon, but if you have automation that relies on BinTray, you should update it to use the new home. — Marshall P.S. The “nightly” snapshots will live there too, as soon as we get that set up.

[GSoC][GSoC21] Proposal for new quad-double type in Boost.Multiprecision
by Fahad Syed 12 Apr '21

12 Apr '21

Greetings, My name is Syed Fahad, and I am a Electrical Engineering undergraduate student at National Institute of Technology, Srinagar. I have outlined a proposal for implementation of a new quad-double type based on David Bailey’s QD package. So the plan outline is to initially implement quad-double and double-double types as a wrapper around the QD packages qd_real and dd_real classes, and write the testing and benchmarking routines. Eventually, write a generic multiple-double class from scratch using the same algorithms as QD, and remove dependency on external libraries wherever possible. I would be very interested in feedback, questions, and comments. I am looking for supervisors/mentors to undertake this project as part of GSoC 2021. Apologies for the apparently late proposal submission. The link to my proposal is: https://docs.google.com/document/d/10_y6bMk8YkBXXZk5iZr4zJafBwsmJI910Tl K8mDYa80/edit?usp=sharing Best, Syed Fahad.
