|
||
|
|
We are happy to announce the release of GNU Mes 0.25!
|
||
|
|
|
||
|
|
Although it's been only nine months since the previous release, this
|
||
|
|
release represents 116 commits over two years by six people. This
|
||
|
|
release brings RISC-V64-linux support.
|
||
|
|
|
||
|
|
We are excited that the NLnet Foundation is sponsoring this work!
|
||
|
|
|
||
|
|
What's next?
|
||
|
|
|
||
|
|
Bringing the Full Source Bootstrap to NixOS. Full Guile compatible
|
||
|
|
module support, and support for running Gash and Gash-Utils. Support
|
||
|
|
for bootstrapping gcc-4.6.4, and a Full Source Bootstrap for
|
||
|
|
armhf-linux, and riscv64-linux.
|
||
|
|
|
||
|
|
Enjoy!

* About
|
||
|
|
|
||
|
|
GNU Mes is a Scheme interpreter and C compiler for bootstrapping the
|
||
|
|
GNU System. It has helped to decimate the number and size of binary
|
||
|
|
seeds that were used in the bootstrap of GNU Guix 1.0. Recently,
|
||
|
|
version 0.24.2 has realized the first Full Source Bootstrap for Guix
|
||
|
|
<https://guix.gnu.org/en/blog/2023/the-full-source-bootstrap-building-from-source-all-the-way-down/>.
|
||
|
|
The final goal is to help create a full source bootstrap as part of
|
||
|
|
the bootstrappable builds effort <https://bootstrappable.org> for any
|
||
|
|
UNIX-like operating system.
|
||
|
|
|
||
|
|
Mes + MesCC + Mes C Library can build a bootstrappable TinyCC
|
||
|
|
<https://gitlab.com/janneke/tinycc> that is self-hosting. Using this
|
||
|
|
bootstrappable-tcc and the Mes C library we can build an ancient
|
||
|
|
version of the GNU tools triplet: glibc-2.2.5, binutils-2.20.1,
|
||
|
|
gcc-2.95.3. This is enough to bootstrap Guix for i686-linux,
|
||
|
|
x86_64-linux, armhf-linux and aarch64-linux.
|
||
|
|
|
||
|
|
Mes was inspired by The Maxwell Equations of Software: LISP-1.5 --
|
||
|
|
John McCarthy page 13, Guix's source/binary packaging transparency and
|
||
|
|
Jeremiah Orians's Stage0 <https://github.com/oriansj/stage0>, a
|
||
|
|
~500-byte self-hosting hex assembler.

[*] Use a .sig file to verify that the corresponding file (without the
|
||
|
|
.sig suffix) is intact. First, be sure to download both the .sig file
|
||
|
|
and the corresponding tarball. Then, run a command like this:
|
||
|
|
|
||
|
|
gpg --verify mes-0.25.tar.gz.sig
|
||
|
|
|
||
|
|
If that command fails because you don't have the required public key,
|
||
|
|
or that public key has expired, try the following commands to update
|
||
|
|
or refresh it, and then rerun the 'gpg --verify' command.
|
||
|
|
|
||
|
|
gpg --recv-keys 1A858392E331EAFDB8C27FFBF3C1A0D9C1D65273
|
||
|
|
|
||
|
|
Alternatively, Mes can be installed or updated using Guix:
|
||
|
|
|
||
|
|
guix pull
|
||
|
|
guix install mes
