Hi! Can you recommend some C++ libraries for making GUI interface? Also I know Tiled the Map Editor for creating maps for games, and I'm looking for some app for creating Graphical Interfaces for my future apps with a scaling elements feature (as I can do this in InkScape for example), and with many other features also. But I ...

Like every major GCC release, this version will bring many additions, improvements, bug fixes, and new features. GCC 15 is already the system compiler in Fedora 42. Red Hat Enterprise Linux (RHEL) users will get GCC 15 in the Red Hat GCC Toolset. It's also possible to try GCC 15 on Compiler Explorer and similar pages. ...

Using the -j option is ignored. About two weeks ago I found out that cmake was compiling with only one thread but everything was ok a couple of months ago.

In the Qt 6.7 release, we enabled support for C++20 comparison and also back-ported some of its features to C++17. This blog post will give you an overview of the comparison enhancements we are taking advantage of and offer guidance on implementing them in your custom classes.

Safety Profiles were introduced in 2015 with the promise to detect all lifetime safety defects in existing C++ code. It was a bold claim. But after a decade of effort, Profiles failed to produce a specification, reliable implementation or any tangible benefit for C++ safety. The cause of this failure involves a number of ...

Does the C++ design follow the zero-overhead principle? Should it? I think it should, even if that principle isn’t trivial to define precisely. Some of you (for some definition of “you”) seem not to. We– WG21 as an organization – haven’t taken it seriously enough to make it a requirement for acceptance of new ...
