Subject: GNU Mes 0.17 released
|
|
|
|
<#secure method=pgpmime mode=sign>
|
|
We are delighted to announce the release of GNU Mes 0.17, representing
|
|
64 commits over 6 weeks.
|
|
|
|
Mes is now an official GNU package and we have bootstrapped gcc-4.7.4
|
|
for x86-linux with a reduced binary seed (i.e., without regular toolchain).
|
|
|
|
Next targets:
|
|
|
|
- upstream the x86 Mes bootstrap to GuixSD
|
|
- create a x86_64 Mes C Lib, see if that is is enough to bootstrap x86_64
|
|
- reduce the 1MB ASCII M1 seed to ~5000 LOC/~100KB of M2 source
|
|
- create a plan for Geesh and Gash and use them to reduce the
|
|
bootstrap binary dependencies
|
|
- and/or otherwise reduce the bootstrap binary dependencies
|
|
|
|
Packages are available from Guix's wip-bootstrap branch.
|
|
|
|
* About
|
|
|
|
GNU Mes[0] aims to help create full source bootstrapping for GNU/Linux
|
|
distributions such as GuixSD[1] as part of the bootstrappable builds[2]
|
|
effort.
|
|
|
|
It consists of a mutual self-hosting Scheme interpreter written in
|
|
~5,000 LOC of simple C and a Nyacc-based C compiler written in Scheme.
|
|
This mes.c is being simplified[3] to be transpiled by M2-Planet[4].
|
|
|
|
The Scheme interpreter (mes.c) has a Garbage Collector, a library of
|
|
loadable Scheme modules-- notably Dominique Boucher's LALR[5],
|
|
Pre-R6RS portable syntax-case[6] with R7RS ellipsis, Matt Wette's
|
|
Nyacc[7] --and test suite just barely enough to support a simple REPL
|
|
and simple C-compiler: MesCC.
|
|
|
|
Mes+MesCC can compile an only lightly patched TinyCC[8] that is
|
|
self-hosting. Using this tcc and the Mes C library we now have a
|
|
reduced-binary-seed bootstrap for the gnutools triplet: glibc-2.2.5,
|
|
binutils-2.20.1, gcc-4.7.4.
|
|
|
|
Mes is inspired by The Maxwell Equations of Software: LISP-1.5[9] --
|
|
John McCarthy page 13, GNU Guix's source/binary packaging transparency
|
|
and Jeremiah Orians's stage0[10] ~500 byte self-hosting hex assembler.

git clone git://git.savannah.gnu.org/mes.git

|
[*] 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-0.17.tar.gz.sig
|
|
|
|
If that command fails because you don't have the required public key,
|
|
then run this command to import it:
|
|
|
|
gpg --keyserver keys.gnupg.net --recv-keys 1A858392E331EAFDB8C27FFBF3C1A0D9C1D65273
|
|
|
|
and rerun the 'gpg --verify' command.
|
|
|
|
Mes runs from the source tree and can also be built, packaged and
|
|
installed in Guix[SD] from a git checkout by running
|
|
|
|
guix package -f .guix.scm
