    I was bored so I added CAF to pkgsrc, which you can use to install CAF on NetBSD/Linux/macOS and a variety of other Unix-ey platforms that pkgsrc supports:

    https://github.com/NetBSD/pkgsrc-wip/tree/master/actor-frame...

        git clone https://github.com/NetBSD/pkgsrc --depth 1 ~/pkgsrc  
    git clone https://github.com/NetBSD/pkgsrc-wip --depth 1 ~/pkgsrc/wip  
    cd ~/pkgsrc/bootstrap   
    ./bootstrap --unprivileged  
    cd ~/pkgsrc/wip/actor-model  
    ~/pkg/bin/bmake install    
    ~/pkg/sbin/pkg_info -L actor-model
    That is all.

    > Decoupling concurrently running software components via message passing avoids race conditions by design.

    How am I supposed to read this? It's obviously not "message passing eliminates race conditions", so perhaps it's intended to say something like "you need to design the components to avoid race conditions."

    Honestly, the source code of the examples looks rather complicated, like something that should better be generated from a nicer high-level language that has a native actor concept. (Obviously, the power of C++ templates does not come for free - you pay with noisy code and increased cognitive load.)

    In the Docs:Overview [0], the compile and build instructions are not showing up for some reason.

    "Actor" architecture is supposed to enable high developer productivity but it's been a decade since the article so I wonder how it's working out? The most prominent project of which I am aware is FoundationDB.

    If someone's got a nice actor library written in and for C, I'm all hears.

    The activity around C++20 has gotten to the point where I’m skeptical of great libraries like this because I don’t want to learn something third-party when I might be able to use STL equivalents in just a few hundred days.
