[Message part 2 (message/rfc822, inline)]

From: Sergey Fedorov <vital.had <at> gmail.com>
To: bug-guile <at> gnu.org, guile-devel <at> gnu.org
Subject: Guile 3.0.10 fails to build for powerpc-darwin (3.0.9 built earlier)
Date: Sat, 31 Aug 2024 05:20:33 +0800

[Message part 3 (text/plain, inline)]

Greetings,
Could someone take a look, please?

I am not familiar with Guile internals, so need some help with fixing this.
Guile 3.0.9 was building with minimal fixes for Darwin ppc, however I am
unable to get 3.0.10 build.
I have tried to change some configure settings, but the failure is not
sensitive to any, it seems.

The error looks like this:

P. S. Given that it takes about 11 hrs to reach to this point (because
pre-built binaries for ppc32 are broken since guile2, and a full bootstrap
is needed), it is somewhat problematic to debug this blindly without an
idea what could cause this failure.

I believe this was fixed by
<https://git.savannah.gnu.org/cgit/guile.git/commit/?id=aff9ac968840e9c86719fb613bd2ed3c39b9905c>
(see the neat explanation at
<https://wingolog.org/archives/2024/09/26/needed-bits-optimizations-in-guile>).

Confirmed by CI: <https://ci.guix.gnu.org/eval/1667191>.

Thanks,
Ludo’.
