From https://github.com/marler8997/zig-unofficial-releases
I also updated the "Release Process" wiki instructing how to use it.
Long live Mr. Marler!
The launcher got a facelift because of this error:
/code/zig-linux-x86_64-0.11.0-dev.2619+bd3e248c7/lib/std/fmt.zig:2013:9: error: function called at runtime cannot return value at comptime
return &buf;
^~~~~~~~~~~

remaining reference traces hidden; use '-freference-trace' to see all reference traces
Zig gets confused by the requirement in that test in a runtime context.
Your old version of the software released under the old license can
still be used under the terms of the old license.
I have received the following statement from the past contributors
Luis Holanda, Jeremy Volkman and Fabian Hahn:
I hereby confirm that I am the copyright holder or authorized by the
copyright holder of this contribution. As such I hereby confirm that
all contributions made to bazel-zig-cc by me or on behalf of me,

[http://www.apache.org/licenses/LICENSE-2.0]. I am aware that my
previous contributions will still be available under the MIT license
as well. I confirm that I am aware of the bazel-zig-cc teams intention
to release bazel-zig-cc under the Apache 2.0 License from release
[1.0] and onwards, and that the bazel-zig-cc no longer will accept
contributions made under the MIT and that any future submissions from
myself will be considered to be licensed under Apache 2.0 unless I
expressly state otherwise.
Copyright and re-licensing for Google and Uber employees has been
resolved internally.
Since not all contributors took action to re-license the code yet,
portions of bazel-zig-cc remain licensed as MIT.
I have started this project during my personal time with my personal
resources. I am now handing over all copyrights to this code to Uber
Technologies, Inc.
Until now we needed to maintain two versions of the zig launcher: one
for Windows and one for everything else. This was problematic for two
reasons:
1. I do not know powershell and thus keep breaking the Windows wrapper
all the time (see git history of Fabian fixing stuff that I broke).
2. This makes bazel-zig-cc dependent on the system shell, making it not
really hermetic. So the recently added
`--experimental_use_hermetic_linux_sandbox` does not work with
bazel-zig-cc, unless we bind-mount a bunch of stuff: `/usr`, `/bin`,
`/lib`, `/usr/lib:/lib`, `/usr/lib64:/lib64` and `/proc`.
Switching to a Zig-based wrapper solves both issues, and we can do this:
bazel build "$@" \
--experimental_use_hermetic_linux_sandbox \
--sandbox_add_mount_pair=/proc \
<...>
Zig itself still depends on `/proc` for `/proc/self/exe`, so we need to
keep that. I will look into reducing even that dependency separately.
Not all is nice and shiny though: this commit replaces ~80 LOC worth of
shell scripts wrappers with a singe ~300 LOC zig program, which is
arguably harder to understand. However, it is easier to change, at least
for me, because it's a single file with unit tests! Most importantly,
the gnarly code (which resolves paths and sets environment variables) is
cross-platform.
Thanks to Fabian Hahn for testing this on Windows and pointing out
errors.
