Hi Jan,
In your bootstrap path, what is the step after Mes? I guess it would be using mescc to compile some C program - but if that is right, which program?
Regards - Neil

Subject: Mes 0.8 released
I am pleased to announce the release of Mes 0.8, representing 34
commits over 3 weeks. Mescc now produces object files in the hex2
ascii output format compatible with the stage0 linker.
Special thanks to Jeremiah Orians for support with MESCC_Tools and
hex2, more goodness to follow soon!
* About
Mes aims to create full source bootstrapping for GuixSD: an
entirely source-based bootstrap path. The target is to [have
GuixSD] boostrap from a minimal, easily inspectable binary --that
should be readable as source-- into something close to R6RS
Scheme.
It currently consists of a mutual self-hosting [close to Guile-]
Scheme interpreter prototype in C and a Nyacc-based C compiler in
[Guile] Scheme.
The Scheme interpreter prototype (mes.c) has a Garbage Collector,
a library of loadable Scheme modules-- notably Dominique Boucher's
LALR[1], Pre-R6RS portable syntax-case[2] with R7RS ellipsis, Matt
Wette's Nyacc[3] Guile's PEG[4] --and test suite just barely
enough to support a simple REPL (repl.mes) and simple C-compiler
(mescc.mes) that can produce the second initial ELF binary from
binary from mes.c, in only about 2h30'.
Mes was inspired by The Maxwell Equations of Software: LISP-1.5[5]
-- John McCarthy page 13, GNU Guix's[6] source/binary packaging
transparency and Jeremiah Orians's stage0[7] bootstrap project.
* Download
git clone https://gitlab.com/janneke/mes
wget https://gitlab.com/janneke/mes/repository/archive.tar.gz?ref=v0.8 -O mes-0.8.tar.gz
Mes runs from the source tree and can also be built, packaged and
installed in Guix[SD] by the usual
guix package -f guix.scm
* Changes in 0.8 since 0.7
** Mescc
*** Mescc now depends on the hex2 linker from MESCC_Tools[9].
Direct ELF output support has been removed.
ELF symbol and string table creation has been removed.
*** Mescc now has experimental annotation support for hex2.
*** Mescc has experimental annotation support for hex2.
*** Mescc has been simplified by leveraging use labels in hex2 output.
*** Mescc now supports continue in loops.
*** Mescc now compiles to hex2 object files.
** Language
*** 1 new function
list-index.
Greetings,
janneke
