Subject: [bug#49565] [PATCH core-updates] gnu: bootstrap: Use %current-target-system to decide bootstrap path
Date: Thu, 15 Jul 2021 22:31:43 -0300	[thread overview]
Message-ID: <20210716013143.901859-1-bauermann@kolabnow.com> (raw)
In-Reply-To: <20210715004613.763843-1-bauermann@kolabnow.com>

When cross-building a non-x86 gcc-toolchain on an x86 machine,
‘%current-target’ has the x86 system value and Guix tries to use the
mesboot packages for the bootstrap – which don't work because they’re
currently x86-only.

Therefore look at ‘%current-target-system’ first, which has the non-x86
system value.

* gnu/packages/bootstrap.scm (%bootstrap-inputs): Check
‘%current-target-system’ before ‘%current-system’ to decide whether to use
the mesboot path.
* gnu/packages/commencement.scm (%bootstrap-inputs+toolchain): Ditto.

Hi,

As Maxime Devos mentined previously, glibc-mesboot is only supported on
i686-linux and x86_64-linux and not powerpc64le-linux so it’s strange that
it’s being built on my system. Investigating further, I believe the the
problem is the one described on the commit message above.

With the patch applied on core-updates, I can now get the same error that
the CI is getting when trying to cross-compile a gcc-toolchain package, as
seen here:

https://ci.guix.gnu.org/build/667452/details

But I can’t explain why I see this problem on my machine while it doesn’t
happen on the CI one. Perhaps because I’m running Guix on a foreign distro
(Ubuntu), while the CI presumably uses Guix System?

Here are the derivations that are built now:
