Progress on the Hurd; new state of wip-hurd-vm

Progress on the Hurd; new state of wip-hurd-vm

[Jan Nieuwenhuizen]

Hello,

I just reset wip-hurd-vm to ba6bdb0d0b gnu: guix: Run `make update-guix-package'.

Like before, you should be able to run

    ./pre-inst-env guix build -f gnu/system/hurd.scm

on it to get a VM and start it doing something like

    guix environment --ad-hoc qemu -- qemu-system-i386 -enable-kvm \
     -snapshot -hda $(./pre-inst-env guix build -f gnu/system/hurd.scm) -m 2G \
     -device rtl8139,netdev=net0 -netdev user,id=net0,hostfwd=tcp:127.0.0.1:10022-:2222

The VM now starts the Shepherd which starts the guix-daemon as well as
an openssh daemon.

root shares the system profile, which has been setup for minimalistic
Guix development.  You can build our first package

    ssh root@localhost -p 10022
    guix build --no-offload -e '(@@ (gnu packages commencement) gnu-make-boot0)'

and now also do that from git

    git clone gnu:guix
    cd guix
    ./bootstrap
    ./configure --localstatedir=/var --sysconfdir=/etc --with-courage
    make -j2
    ./pre-inst-env guix build --no-offload -e '(@@ (gnu packages commencement) gnu-make-boot0)'

Being able to build packages from git greatly reduces the round-trip
time :-)

The Shepherd integration needs more work.  Also, the tip of that branch
shows some troublesome commits that hack around cross-compiling guix to
the Hurd.

Greetings,
janneke

Hello,

I just had a tour of that branch, it looks like there are interesting
patches wrt cross-building, aren't those ready for upstream (core-
updates maybe) ?

I'm looking at the first one (for perl) for example...

I've been trying to cross-compile the binary-tarball to new arches,
without any success, all failing the same way, on perl...

And when it hit me that there is a recurring theme in those failures
I found a few issues and ML posts about the same problem.

So, what's the status of those patches ?

Yes, some of them (gnutls, git, python) have just been cleaned-up and
applied to core-updates.

Ah, that one took some review and effort, see https://bugs.gnu.org/40698
and has now been applied too.

Hard to tell!  Some of those are ready, others need review, others need
work.

The autotools patches need review, but they work.  The patches to
cross-build guix need some discussion and worse, cross-compiling guix
currently uses a terrible kludge; so while also that "works", its still
under development.

Oh, funny, I stumbled upon perl-cross, just after having sent my email.

Thanks a lot for your work !
And also for the status update.

As reported by apteryx on IRC yesterday, this command may fail for you
unless you have already built the bootstrap binaries for the Hurd.

If you are new to the Hurd you must first build the bootstrap-binaries
from the core-updates branch.  The easiest to do that is by using the
command above to build the VM.

This should be fixed once we get the `guix' package to cross-builds
without some of the hacks that are now used near the tip of the
wip-hurd-vm branch.
