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. diff --git a/gnu/packages/chez.scm b/gnu/packages/chez.scm index c6420a980e..ab6eaba6bd 100644 --- a/gnu/packages/chez.scm +++ b/gnu/packages/chez.scm @@ -692,10 +692,12 @@ (define-public chez-scheme-for-racket-bootstrap-bootfiles (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))))))))))))) + ;; Temporary handling of builds on non-x86 architectures, + ;; see https://github.com/racket/racket/issues/3948 + ;; Autodetect in rktboot only addresses x86 archs, so far. + #$@(let ((m (or (racket-cs-native-supported-system?) + (nix-system->pbarch-machine-type)))) + #~("--machine" #$m)))))))))))) (supported-systems (package-supported-systems chez-scheme-for-racket)) (home-page "https://github.com/racket/ChezScheme") --=-=-=--

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. > > [...] > > 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 > flag.

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. -Philip --nextPart9862253.CDJkKcVGEf Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part.

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 ,---- | string-append: contract violation | expected: string? | given: #f | argument position: 1st | other arguments...: | ".def" | context...: | /tmp/guix-build-chez-scheme-for-racket-bootstrap-bootfiles-9.9.9-pre-r= elease.14.drv-0/source/racket/src/rktboot/machine-def.rkt:6:0: open-file-wi= th-machine.def-redirect | error: in phase 'build': uncaught exception: | %exception #<&invoke-error program: "/gnu/store/0n4skakcg05bbq9sq7g00j2zm= 25xh4wa-racket-vm-bc-8.8/opt/racket-vm/bin/racket" arguments: ("../rktboot/= main.rkt") exit-status: 1 term-signal: #f stop-signal: #f>=20 | phase `build' failed after 14.3 seconds | command "/gnu/store/0n4skakcg05bbq9sq7g00j2zm25xh4wa-racket-vm-bc-8.8/opt= /racket-vm/bin/racket" "../rktboot/main.rkt" failed with status 1 | builder for `/gnu/store/d04mbj02vzjv0ljcqy2lxs33scz7kjz0-chez-scheme-for-= racket-bootstrap-bootfiles-9.9.9-pre-release.14.drv' failed with exit code 1 | @ build-failed /gnu/store/d04mbj02vzjv0ljcqy2lxs33scz7kjz0-chez-scheme-fo= r-racket-bootstrap-bootfiles-9.9.9-pre-release.14.drv - 1 builder for `/gnu= /store/d04mbj02vzjv0ljcqy2lxs33scz7kjz0-chez-scheme-for-racket-bootstrap-bo= otfiles-9.9.9-pre-release.14.drv' failed with exit code 1 `---- (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 Tim L=C3=A1 Fh=C3=A9ile P=C3=A1draig sona dhaoibh!
