#+TITLE: Porting GNU Mes
* Porting GNU Mes to ARM
The ARM port can be found in wip-arm on savannah.
For development, we use Guix's qemu-binfmt-service-type.
** Guix Setup, see [[info:guix#Virtualization%20Services][Virtualization Services]].
Add something like
#+BEGIN_SRC scheme
(service qemu-binfmt-service-type
(qemu-binfmt-configuration
(platforms (lookup-qemu-platforms "arm"))
(guix-support? #t)))
#+END_SRC
to your config.scm and run guix system reconfigure.
** Setup environment
For example (note: ARM is no longer a 'port', see HACKING)
#+BEGIN_SRC bash
guix shell --system=armhf-linux --pure bash coreutils diffutils findutils gawk gcc-toolchain grep git guile gzip help2man make mescc-tools nyacc openssh-sans-x pkg-config sed tar texinfo
#+END_SRC
** Try it
#+BEGIN_SRC bash
CC=gnu-triplet-gcc ./configure --with-courage --with-system-libc
./simple.sh
#+END_SRC
some failures are expected.
** Build it
#+BEGIN_SRC bash
./configure --with-courage --with-system-libc
make MES=guile
make check
#+END_SRC
expect many failures. Non-system-libc, i.e. using the Mes C Library is currently WIP.
* Porting GNU Mes to x86_64
The x86_64 port is almost done, only a few bugs remain. The Guix
bootstrap for x86_64 uses x86 mes and that is not expected to change.
* Porting GNU Mes to GNU/Hurd
The Hurd port can be found in wip-hurd on savannah. For development, we
use a Debian GNU/Hurd vm.
* Porting GNU Mes to FreeBSD
The FreeBSD port can be found in wip-freebsd on savannah.
* Porting the Reduced Binary Seed bootstrap to NixOS
The NixOS port of the Reduced Binary Seed bootstrap lives on the
mes-bootstrap branch in https://github.com/xwvvvvwx/nixpkgs
* Porting the Reduced Binary Seed bootstrap to Debian GNU/Linux
To port the Reduced Binary Seed bootstrap to a traditional distribution
such as Debian, two things need to happen: the bootstrap must be ported
and the distribution build process needs to change to start from a only
binary seed.
The porting aspect is probably easiest: we start by packaging GNU Mes as
a regular package. Having Mes built as a regular package, we can then
build a bootstrap Mes. This bootstrap Mes can be used to build tinycc,
and so on.
Once we have shown that the Debian base system can be bootstrapped from
a Reduced Binary seed, thus significantly reducing the Trusted Computing
Base (TCB), strategic decisions about the build process can start.
