Have you give a look to dlang? or even rust

Rust's compile times are even worse.

  That's only because they just started working on incremental compilation, it will get faster soon enough.

    I've heard the same thing a year ago. It didn't happen. See this 2016 roadmap from August 2015 for example: https://blog.rust-lang.org/2015/08/14/Next-year.html https://blog.rust-lang.org/2015/08/14/Next-year.html

      A lot of things did happen. One of them is having the option to check the source which is much faster than compiling. 99% of the time you're compiling code in rust is to run the borrow checker and fix those errors.

        That's indeed something where Rust is a lot better than C++. But for many projects (like games or GUI apps) you'll need to iterate with changes which can only be seen in the final product. So you'll need a complete build to run the binary.

        Fair enough. However games and GUI apps are still a small percentage of applications developed in rust. I want that to change, of course. I just wanted to point that out. I'm personally writing a game in Rust but the main logic is written in a compile-to-JS language and uses V8, so the issue doesn't affect me.

      The basics have happened, and you can use it right now. It's not on by default yet though. Still a ton of work being done.
      - jhasse 9y ago
        Yeah, last time I've tried it (a few months ago) incremental build times where a lot slower for a full rebuild and only about 10 % faster when touching a single rs file. I've already found a few issues and it seems you guys are working on it :) But as of now: C++ incremental build times (with the right build system) are a lot better than Rust's.

      Incremental compilation is something that no major compiler for any ahead-of-time compiled language anywhere does. It's one of the most advanced features in any compiler, and as such it's taking time to implement. No C++ compiler I know of is even thinking of it. As the first post here in this thread mentions, going down the C++ road of header files might have gotten us some short term wins, but ultimately it hits a brick wall. Incremental compilation is inescapable.

        I surely do consider Visual C++ a major compiler for any ahead-of-time compiled language. It does incremental compilation and incremental linking. I would be quite happy if cargo was half as fast as my UWP projects.

  They seem to be worse, but does anyone have information on how it scales?
