CMake 3.16 added support for precompiled headers & unity builds - what you need to know

By onqtam | Dec 21, 2019 11:12 AM | Tags: None

Modules are coming in C++20 but it will take a while before they are widely adopted, optimized and supported by tooling - what can we do right now?

CMake 3.16 added support for precompiled headers & unity builds - what you need to know

by Viktor Kirilov

From the article:

CMake 3.16 introduced native support for precompiled headers and unity builds - we no longer need to rely on clunky 3rd party CMake scripts! This is a complete guide on what the 2 techniques are, how to apply them and what to look out for. Builds could easily drop to less than 20% of the time they originally took.

Slow builds don’t just waste time - they also break the ‘flow’ (context switching) and discourage refactoring and experimentation - how do you put a price on that?

From the article:

float yScale = 1.0 / tan((3.141592538 / 180.0) * fov / 2);

There's a tiny typo in the Pi number (3,141592653...): the number "6" is missing at the 7th decimal place.

C++20 and ReSharper C++

Do you plan to start using C++20 any time soon?

C++20 and ReSharper C++

by Phil Nash

From the article:

In July of this year, in the German city of Cologne, the ISO WG21 committee approved the full draft of C++20. After Belfast, in November, we now have just one more meeting (in Prague) to deal with national body comments and get their approval. That means that, barring any catastrophes, C++20 will become the current standard sometime after February of next year.

So C++20 is still in the future, but we now have a very good idea of everything that will be in it. Large sections of it have already been implemented in several compilers. But it’s not just the compilers that are getting ahead of the game. ReSharper C++ supports many of these features already, too – often with extra analysis and insights enabled by them.

Support for C++20’s Concepts in CLion--Anastasia Kazakova

Support for C++20’s Concepts in CLion

by Anastasia Kazakova

From the article:

Concepts are one of the biggest features coming in C++20, and knowing that, we’ve been thinking about supporting Concepts in CLion for quite a while. Enter Saar Raz with his C++20’s Concepts implementation in Clang! Long story short, we have been collaborating with Saar to merge his branch into our custom Clangd-based language engine in CLion, and started implementing some nice IDE features on top. Sounds ambitious enough, but we have thoroughly enjoyed the experience so far! A very early result of this collaboration was used by Saar in his CppCon 2019 talk on Concepts...

Will you try it?

AddressSanitizer (ASan) for Windows with MSVC

by Augustin Popa

From the article:

We are pleased to announce AddressSanitizer (ASan) support for the MSVC toolset. ASan is a fast memory error detector that can find runtime memory issues such as use-after-free and perform out of bounds checks. Support for sanitizers has been one of our more popular suggestions on Developer Community, and we can now say that we have an experience for ASan on Windows, in addition to our existing support for Linux projects...
