In "(guix) Additional Build Options", documenting the --system
option,
the Guix manual says:
Similarly, when transparent emulation with QEMU and
‘binfmt_misc’
is enabled (*note ‘qemu-binfmt-service-type’: Virtualization
Services.), you can build for any system for which a QEMU
‘binfmt_misc’ handler is installed.
So, I added this -- the exact configuration from "(guix)
Virtualization Services" in the manual -- to my operating-system’s
services:
(service qemu-binfmt-service-type
(qemu-binfmt-configuration
(platforms (lookup-qemu-platforms "arm"
"aarch64"))))
And `guix system reconfigure'd. The service is running:
# herd status qemu-binfmt
Status of qemu-binfmt:
It is running since Mon Dec 30 20:47:07 2024 (6 days ago).
Running value is #t.
It is enabled.
Provides: qemu-binfmt
Requires: file-system-/proc/sys/fs/binfmt_misc
Will be respawned.
If I try to build a package with --system specified, it fails due
to the wrong architecture:
$ guix build --system=aarch64-linux guix
The following derivation will be built:

The "(guix) Native Builds" part of the manual mentions that this
error will occur "If the ‘binfmt_misc’ mechanism is not setup
correctly..."
What is the correct way to set Guix up so I can build
aarch64-linux packages on x86_64-linux?
Thanks,
