For other readers, this thread is very similar to

Maybe also pass --system=aarch64-linux for QEMU emulation? I see that
the Guix repo’s gnu/platforms/arm.scm does both
--target=aarch64-linux-gnu and --system=aarch64-linux. No idea if it
helps. Eventually Guix should not require --system though, I think.

In the core-updates-frozen branch, there is Meson cross-compilation
support since July 14 <https://issues.guix.gnu.org/49025> commit
8456581375cf03c46005d00907f8fdd1f5615f1e. Either wait until it lands
in Guix proper (somewhat soon), or try the core-updates-frozen branch.
However, for me that failed at cross-compiling dosfstools (with
--target only, no --system).

Yes, I think it takes that long.

Is bordeaux enabled? See:

Which package specifically?
This is when you run `guix build --system=aarch64-linux …`?

There are PinebookPro images:
https://guix.gnu.org/en/download/latest/
But I don’t know if there are rockpro64 images; probably not, since
there is no image in the guix repo nor cookbook.

Yes, this is faster.

There is (local-file "…" #:recursive #t) and similar for other kinds
of file.
Cannot answer the rest.
