*** GUIX SYSTEM DISK-IMAGE HANGS PINEBOOK PRO ***

*** GUIX SYSTEM DISK-IMAGE HANGS PINEBOOK PRO ***

[Brian Woodcox]

I am using a Pinebook Pro (aarch64) to build a disk image.  However the build process stops very quickly when it gets to the ...-disk-image.drv...

The guix --version is guix (GNU Guix) d673993...1ce0f20 

The command that I am issuing is:

guix system disk-image -e "(@ (gnu system install) rockpro64-installation-os)"

I did not add --system=aarch64-linux as that should be implicit, since I am running this on an aarch64 system.

Also target-arm32 is required, so I had to edit the guix/utils.scm file so that would be set as true as follows (this is just an ugly hack):

(define (target-arm32?)
  (string-prefix? "aarch" (or (%current-target-system) (%current-system))))

Using strace on the command does not yield any obvious error.

I had a similar issue building a disk-image. It was on an x86 machine, and the
build would error out right at that point. The fix was to put add my user to
the 'kvm' group.

From looking at top during the build, it seems that the disk-image derivation
is doing something with qemu. Is there even ARM support in the KVM? I am
illiterate on that kind of thing, but hopefully this gives you a lead.

Thanks for the tip.  Unfortunately the gnu/build/vm.scm file explicitly states that it is buggy on ARM32 boards and should not be used, even if available.  I would assume that would be the case for aarch64 as well.

I didn't have much luck when I tried to build for my pine64. Also with
similar issues. I'll share the diff I have but mine hung at the same
place, when it was using QEMU to build the image.
