Subject: Test failures in binfmt emulated builds
Date: Tue, 14 Mar 2023 15:19:36 -0400

The following emulated build using binfmt should work according to the
documentation example at
https://guix.gnu.org/manual/en/html_node/Native-Builds.html

$ uname -m
x86_64


The package was previously built on an aarch64 offload machine:

$ file $(guix build --system=aarch64-linux hello)/bin/hello
/gnu/store/s2qnbdlrwlx47h5p6rxlylny1259srmj-hello-2.12.1/bin/hello:
ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), dynamically
linked, interpreter
/gnu/store/gfjp8gfv4xxschbaxvldpigadfwqazhw-glibc-2.33/lib/ld-linux-aarch64.so.1,
for GNU/Linux 2.6.32, stripped


Successfully executed using binfmt emulation:

$ $(guix build --system=aarch64-linux hello)/bin/hello
Hello, world!


A locally emulated check build fails during the test phase:

This kind of problem is really a bug/limitation in QEMU.  I'd suggest
forwarding this report to them if you'd like to have it resolved.

Closing.
