Take the Meeting C++ Community Survey!

Launching the Meeting C++ Community Survey

by Jens Weller

From the article:

One thing then often has bugged me when looking at the C++ community is that we don't really had good numbers on most things. Jetbrains, ISOCPP and Bartek's coding blog have launched surveys in the last years, which changed this a little. Also I've been doing some surveys on Twitter, giving some limited insight into C++ related topics. But Twitter surveys are very limited, and for a long time I had an idea on how to make this a continuous survey.

From the article:

Happy new years! The year has begun, and lots of C++ User Groups have their first meeting of 2020.

Would like to start your own group or looking for ideas in running your current group? Watch my talk from CppCon:

ACCU 2020 Registration

About the conference:

Historically, ACCU has a lot of C++ and C content, and is proud of that: ACCU is the foremost annual conference for people interested in C++ and C, at least in and around the UK. But it is not just a C++ and C conference, ACCU is about programming in whatever language people are using, with whatever tools and processes people are using: D, Chapel, Java, Kotlin, C#, F#, Groovy, Rust, Go, Python, Ruby, Lisp, to name just a few programming languages about which there have been sessions at ACCU conferences. Git, CMake, Meson, TDD, BDD, allthese tools and techniques have been the focus of sessions at ACCU. The ACCU Conference is looking for sessions that will be interesting to people who create software.

Our keynote speaker are this year: Patricia Aas, Emily Bache, Kevlin Henney and Sean Parent

There are these preconference workshops the day before the conference:

 

 

C++ Standard Version Mix-up

By Christoph Cullmann | Jan 5, 2020 12:32 AM | Tags: None

Libraries compiled with different C++ standard versions might not be as compatible as wanted.

C++ Standard Version Mix-up

by Christoph Cullmann

From the article:

We work with MSVC 2019 on Windows and all worked fine with LLVM 9.x, but with master, close to all my tests did now segfault in aligned_free.

Some months ago, the implementation of DenseMap got improved to use the allocate_buffer/deallocate_buffer functions to use (if possible) aligned allocation.

Unfortunately, this means, during the compilation of the library, the checks there ensure it doesn’t use these code paths, on the other side, during compilation of our tools, it does, as the allocation functions are fully inline in the header including the feature checks.

C++ on Sea 2020 - Student and Volunteer programmes

By philsquared | Jan 5, 2020 12:31 AM | Tags: None

Our Student and Volunteer programmes for 2020 are now open.

Students and Volunteers, programmes for 2020

From the article:

These provide valuable opportunities for those who might not otherwise be able to attend to benefit from the conference - either very cheaply, or even for free!


Full details can be found on the Students and Volunteers programme pages, respectively.


If you are a student, but would also like to volunteer, you may apply to both programmes.


Note that applications for volunteers will remain open until 26th January 2020.

C++ coroutines: The co_await operator and the function search algorithm--Raymond Chen

C++ coroutines: The co_await operator and the function search algorithm

by Raymond Chen

From the article:

So you’re following along Kenny Kerr’s blog and you get to the part where he uses co_await on a time duration:

co_await 5s;​

so you try it:

#include <chrono>
using namespace std::chrono;

winrt::IAsyncAction Delay10Seconds()
{
   co_await 10s;
   co_return;
}

and you get the error message

no callable ‘await_resume’ function found for type ‘Expression’ where Expression=std::chrono::seconds
