Compiling a C++ program entirely from source (no sysroot, no hostlibs)

This demo showcases the current state of my project to build a fully hermetic cross-compilation c/c++ bazel toolchain.

This video shows the entire compilation process for a simple hello world in c++ that manually depends on every default libs (libc, libc++, compiler-rt, CRT) that are built entirely from zero (no prebuilts, no sysroot).

The entire build logic is based on the awesome work of the ziglang team and reuses a lot of what zig cc actually does but with just Bazel and clang.

The next step is to wrap this in a toolchain so that depending on defaultlibs is implicit.

<head>
  <link rel="stylesheet" type="text/css" href="/assets/asciinema-player.css" />
</head>
<body>
  <div id="player"></div>
  <script src="/assets/asciinema-player.min.js"></script>
  <script>
    AsciinemaPlayer.create(
      '/assets/709862.cast',
      document.getElementById('player'),
      { cols: 174, rows: 44 }
    );
  </script>

While this site doesn't provide GIF conversion at the moment, you can still do it yourself with the help of asciinema GIF generator utility - agg.

Once you have it installed, generate a GIF with the following command:

agg https://asciinema.org/a/709862 demo.gif
