  • Swift and Cute 2D Game Framework: Setting Up a Project with CMake
    I really recommend Bazel (https://bazel.build). - Source: Hacker News / 4 months ago
  • Why Is This Site Built with C
    Agree regarding easiness of building rust (`cargo build`), extremely satisfying (git clone and cargo build...) Does anyone have any comments on Bazel[1] because I'm kind of settling on using it whenever it's appropriate (c/c++)?.. [1] https://bazel.build/. - Source: Hacker News / 6 months ago
  • 7 Ways to Use the SLSA Framework to Secure the SDLC
    To achieve reproducibility, your build process must control for environmental differences like timestamps, file ordering, or machine-specific configurations. Tools like Bazel or Nixprovide deterministic build systems that lock down these variables. For instance, Bazel uses a content-addressable cache, meaning the same source code and dependencies always result in the same build outputs, even when run on different... - Source: dev.to / 11 months ago
  • Contributing To Open Source - C++ Edition
    Despite following all the steps (on both Windows and Unix), I couldn't get the cmake build to succeed. After several hours of debugging, I decided to try another build method provided by the project, using bazel, which was much simpler. - Source: dev.to / 12 months ago
  • How to effectively work in big codebases
    Many big companies have built their own tools to reign in this complexity and make it easier and faster for developers to work on large, multi-language code bases. Meta has buck, Amazon has brazil, and Google has bazel. But from my experience, especially, with brazil, these tools also have some rough edges, so understanding how they work can go a long way. - Source: dev.to / about 1 year ago

  • Learn Makefiles
    Than checked Autotools and shared the head. At the very same time Meson[1] appeared and the thing with Builds is solved :) [1] https://mesonbuild.com. - Source: Hacker News / 4 months ago
  • cargo-c common questions
    With cargo-c I try to use the best practices to support as many platform as possible, trying to stay in sync with what meson does. Sadly what is conceptually trivial, installing a package, has lots of details that are platform-specific. - Source: dev.to / about 1 year ago
  • Rust Without Crates.io
    I went to mesonbuild.org and it doesn't match the description (some sort of betting site? I didn't stick around ...), and a search turned up: https://mesonbuild.com/. - Source: Hacker News / almost 2 years ago
  • Makefile Tutorial
    Came here to post the same. The answer for How to build software? is Meson[1] for C and C++ and also other languages. Works well on Windows and Mac, too. Iโ€™ve written a small Makefile to learn the basic and backgrounds. Make is fine. But the next high-level would have been Autotools, which is an intimidating and weird set of tools. Most new stuff written in C/C++ use now Meson and it feels sane. [1]... - Source: Hacker News / about 2 years ago
  • CMake x make?
    If you are very fortunate, you'll be able to choose something else. I like meson myself: it looks a bit like python, it's popular, small, simple, well-documented, easy to install and update, and it works well everywhere. Source: about 2 years ago
