cmake ftw

CMake also does sequential configuration AFAIK. Is there any work to improve on that somewhere?

  • Meson and cmake in my experience are both MUCH faster though. It’s much less of an issue with these systems than with autotools.

    • Just tried reconfiguring LLVM:

          27.24s user 8.71s system 99% cpu 36.218 total
      

      Admittedly the LLVM build time dwarfs the configuration time, but still. If you're only building a smaller component then the config time dominates:

          ninja libc  268.82s user 26.16s system 3246% cpu 9.086 total

You mean cargo build

  • ... can cargo build things that aren't rust? If yes, that's really cool. If no, then it's not really in the same problem domain.

    • No it can't.

      It can build a Rust program (build.rs) which builds things that aren't Rust, but that's an entirely different use case (building non-Rust library to use inside of Rust programs).

    • There's GprBuild (Ada tool) that can build C (not sure about C++). It also has more elaborate configuration structure, but I didn't use it extensively to tell what exactly and how exactly does it do it. In combination with Alire it can also manage dependencies Cargo-style.
