gnu: chez-scheme-for-racket-bootstrap-bootfiles: change for aarch64.
* gnu/packages/chez.scm (chez-scheme-for-racket-bootstrap-bootfiles):
Temporary change for build on aarch64, making racket available on aarch64.
Architecture autodetect in rktboot only addresses x86 archs, so far.
This work-around sets the architecture, looked up in translation table,
explicitly. The long term solution should be to fix rktboot to include
other natively supported architectures in the autodetect mechanism.
cf. https://github.com/racket/racket/issues/3948
[arguments] use --machine even when architecture is supported by Racket's
fork of ChezScheme.

Thanks again for your investigation of this problem! As I commented on the
upstream issue at <https://github.com/racket/racket/issues/3948>, I still
think this is an upstream bug (and your analysis helped a great deal in finding
the root cause), but the approach in your patch is probably the easiest way to
fix things for Guix users for now. I'd just ask that you add a comment
referencing the upstream issue and with some explanation, because it's not my
preferred long-term approach.

The "rktboot" scripts (which simulate enough of Chez Scheme to bootstrap its
bootfiles) are supposed to be able to infer right machine type for the current
platform, at least if the platform is natively supported. The problem is that
the upstream code to doesn't actually work on architectures other than i386
and x86_64.

This is a good work-around. The reason I'd like to avoid it in the long run is
that, ideally, I'd like to get us out of the business of managing Chez machine
types and the translation from normal architecture and OS strings. I think
we'll at least be able to eliminate `%chez-features-table` once the ongoing
work to reunify upstream Chez Scheme with Racket's branch is complete.
Reducing the number of places where we have to use these machine-type-
producing functions should help advance that goal, so I'd prefer to have a
comment here reminding us that we can reconsider "--machine" once <https://
github.com/racket/racket/issues/3948> is fixed.

Hi Guix Team,
tl;dr;
The recipe for package 'chez-scheme-for-racket-bootstrap-bootfiles' (a
dependency for racket-8.*) needs to use the --machine flag to build on aarc=
h64
(and possibly also ppc32, the other non-x86 architectures supported by the
Racket fork of Chez Scheme). I therefore suggest the attached patch to make
building and using Racket possible on aarch64 Guix.
End of tl;dr;
A few weeks ago I wanted to use Racket on Guix on aarch64, but was made awa=
re,
that Racket was not available as a substitute and it did not build. On the
other hand, recent versions of Racket were available on Raspberry Pi OS whi=
ch is
explicitly running on aarch64. The machine I am running Guix on actually i=
s a
Raspberry Pi 4B.
So, I dug deeper to find that the problem is that the package
chez-scheme-for-racket-bootstrap-bootfiles
fails with the error

`----
(see, e.g. the build [442314 on ci.guix.gnu.org]).
The Racket fork of Chez is natively supported on aarch64, which is supporte=
d by
comments in module (gnu packages chez), so I went on to find that machine
architecture is communicated in the build process by setting the environment
variable MACH. I haven't looked to verify this, but it seems that this
environment variable is normally set to a guessed value by the zuo build pr=
ocess
(zuo for 'make' in Mandarin?).
The Guix build recipe for chez-scheme-for-racket-bootstrap-bootfiles, thoug=
h, is
not configuring the whole downloaded racket source package but takes the
shortcut of just building ChezScheme in the subdirectory
racket/src/ChezScheme
using the Racket utility
../rktboot/main.rkt
This script would actually accept the flag '--machine' and would set the
environment variable MACH to the value of the argument following the flag.
The problem is that in the case of aarch64 the recipe would not set the fla=
g.
In the recipe for chez-scheme-for-racket-bootstrap-bootfiles in module (gnu
packages chez), we find the lines
,----
| #~(invoke
| (search-input-file (or native-inputs inputs)
| "/opt/racket-vm/bin/racket")
| "../rktboot/main.rkt"
| #$@(if (racket-cs-native-supported-system?)
| #~()
| (let ((m (nix-system->pbarch-machine-type)))
| #~("--machine" #$m)))))))))))))
`----
and, since `(racket-cs-native-supported-system?)' returns `tarm64le', the f=
irst
branch of the if expression is taken, ommitting the flag.
I suggest to change the above code to the following:
,----
| #~(invoke
| (search-input-file (or native-inputs inputs)
| "/opt/racket-vm/bin/racket")
| "../rktboot/main.rkt"
| #$@(let ((m (or (racket-cs-native-supported-system?)
| (nix-system->pbarch-machine-type))))
| #~("--machine" #$m))))))))))))
`----
which sets the flag for natively supported architectures and those supporte=
d by
portable bytecode.
The package (and subsequently Racket) builds on aarch64, the build on x86_64
seems to be unaffected.
It is a simple change which would make a huge difference for Guix users who=
want
to be able to play with Racket on an aarch64 machine.
Cheers
