Bug 892876 – Prefix RAP bootstrap fails at stage 1 on CHOST=aarch64-unknown-linux-gnu: No prefix/linux/arm64 profile

• Product: Gentoo/Alt

Synopsis:

After the recent Prefix cross-compiling changes, the bootstrap-prefix.sh script fails on Linux ARM64 hosts at stage1, just before Portage is set up.  The cause seems to be the lack of a prefix/linux/arm64 profile in ::gentoo.


bootstrap-prefix.sh output:

...
OK!  I'm going to give it a try, this is what I have collected sofar:

Note that two "Your profile is set to ..." lines showed up.  The second one seemed to be the offender.

[Comment 1 sinxccc 2023-03-07 01:01:19 UTC]

I can reproduce this issue on the latest Asahi linux with m1 mac.

[Comment 2 Bob Dröge 2023-03-07 09:20:50 UTC]

I was running into the same issue on a Graviton2 CPU in AWS, but I could fix it by creating an arm64 profile after it failed:

${EPREFIX}/var/db/repos/gentoo/profiles/prefix/linux/arm64

This directory should contain:

$ cat ${EPREFIX}/var/db/repos/gentoo/profiles/prefix/linux/arm64/eapi 
5

$ cat ${EPREFIX}/var/db/repos/gentoo/profiles/prefix/linux/arm64/parent 
../../../default/linux/arm64/17.0
..

$ cat ${EPREFIX}/var/db/repos/gentoo/profiles/prefix/linux/arm64/make.defaults 
# Copyright 1999-2018 Gentoo Foundation
# Distributed under the terms of the GNU General Public License v2

ACCEPT_KEYWORDS="arm64 ~arm64"

# Not sure if this is required as well, seems to be the default:
# CHOST=aarch64-unknown-linux-gnu

Then just run the bootstrap script again and it should continue.
