Subject: [bug#41350] [PATCH 0/3] Use native qemu to build vm-image.
Date: Sun, 17 May 2020 12:01:10 +0200 [thread overview]
Message-ID: <87mu66q3rt.fsf@gnu.org> (raw)
Hi!
Cross-building a vm-image used to be done using a cross-qemu, e.g, qemu-ARM.
That does not work for the Hurd, as there is no qemu-HURD.
This patch switches to cross building vm-images using a native qemu vm. If
there a reason for using qemu-TARGET we may want to make this switch
conditional for cross building to the Hurd?
There is a tricky aspect to this: the "user-builder" includes all the
cross-built packages for TARGET, but we need to hard the native qemu a
native #+LOADER, loading native #+LINUX and #+INITRD.
To accomplish this NATIVE/CROSS mixt, the builder is then run with a native
guile, like so
--8<---------------cut here---------------start------------->8---
(system* #+(file-append (default-guile) "/bin/guile")
"--no-auto-compile"
#$(preserve-target user-builder))
--8<---------------cut here---------------end--------------->8---
while the packages in USER-BUILDER will still be cross-built. However,
because the builder has
(with-extensions gcrypt-sqlite3&co
(use-modules (gnu store database))
...)
this makes the native guile "see" the cross-built .GO files. That would
"only" be a secondary problem except that loading (sqlite3) throws an
exception when dynamic-loading the .SO fails. Seeing it like this I am not so
sure anymore this is a bug, WDYT? ...so instead
...the problem is now avoided by removing the sqlite dependency when
cross-building by not registering closures and postponing the loading of (gnu
store database) and thus (sqlite3).
I have reset wip-hurd-vm onto these changes, so you can also look there.
Doing
./pre-inst-env guix system vm-image --target=i586-pc-gnu --no-grafts \
gnu/system/examples/bare-hurd.tmpl
now produces a pretty nice hurd VM :-)
