Add mes and mescc-tools-extra
mescc-tools-extra contains two important tools: - cp - chmod mes first builds itself from a mes 0.21 seed as used by guix, and then builds a mes 0.22 and then mes 0.22 using that created mes 0.22. It does /not/ use bootstrap.sh as we don't have a proper shell at this point, it has been manually adapted for kaem.

Subject: GNU Mes 0.19 released
|
||||
|
||||
<#secure method=pgpmime mode=sign>
|
||||
We are pleased to announce the release of GNU Mes 0.19, representing
|
||||
100 commits over 10 weeks.
|
||||
|
||||
Mes has now brought the Reduced Binary Seed bootstrap to Guix (bootstrap
|
||||
a GNU/Linux system without binary GNU toolchain or equivalent) and work
|
||||
is ongoing to audit and verify this bootstrap path in NixOS.
|
||||
|
||||
This release introduces strings as byte-array, hash-tables and native
|
||||
structs. While that does increase the footprint somewhat, it fixes
|
||||
our performance issue; tinycc is now compiled in ~8min (WAS: ~1h30).
|
||||
|
||||
Next targets:
|
||||
|
||||
- translate mes.c into unsnarfed mes.M2
|
||||
- use Gash to remove bash, coreutils&co, grep, sed, tar from the Guix
|
||||
bootstrap binaries
|
||||
- replace the NixOS bootstrap
|
||||
- use dietlibc, uClibc, ... for bootstrapping GNU (bash, binutils,
|
||||
gcc, tar) and remove Mes C lib+gnu?
|
||||
- bootstrap gcc-3.x or 4.x directly, drop initial gcc-2.95.3 target?
|
||||
- have M1+hex2 create gcc/tcc-usable object files? archives?
|
||||
- Debian?
|
||||
- ARM, the Hurd?
|
||||
|
||||
Packages are available from Guix's core-updates branch.
|
||||
|
||||
* About
|
||||
|
||||
GNU Mes[0] brings a Reduced Binary Seed bootstrap[1] to Guix[2] and
|
||||
potentially to any other interested GNU/Linux distribution, and aims
|
||||
to help create a full source bootstrap as part of the
|
||||
bootstrappable builds[3] 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[4] to be transpiled by M2-Planet[5].
|
||||
|
||||
The Scheme interpreter (mes.c) has a Garbage Collector, a library of
|
||||
loadable Scheme modules-- notably Dominique Boucher's LALR[6], Pre-R6RS
|
||||
[portable syntax-case[7] with R7RS ellipsis, Matt Wette's Nyacc[8] --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[9] 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-2.95.3. This is enough to bootstrap Guix for
|
||||
i686-linux and x86_64-linux.
|
||||
|
||||
Mes is inspired by The Maxwell Equations of Software: LISP-1.5[10] -- John
|
||||
McCarthy page 13, GNU Guix's source/binary packaging transparency and
|
||||
Jeremiah Orians's stage0[11] ~500 byte self-hosting hex assembler.
|
||||
|
||||
* Download
|
||||
|
||||
git clone git://git.savannah.gnu.org/mes.git
|
||||
|
||||
Here are the compressed sources and a GPG detached signature[*]:

|
||||
|
||||
[*] 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-0.19.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 from a git checkout by running
|
||||
|
||||
guix package -f .guix.scm
