Subject: Dealing with non-ASCII file names in BOOTSTRAP-ORIGIN
Date: Mon, 18 Jul 2022 21:37:44 +0200	[thread overview]
Message-ID: <87bktmnref.fsf@gnu.org> (raw)

Hi Guix,

I tried switching to GCC 11 on the core-updates branch, but it fails
early when attempting to repack the GCC source code for GCC-BOOT0,
because some files in its test suite contains non-ASCII characters:

--8<---------------cut here---------------start------------->8---

Hunk #1 succeeded at 4623 with fuzz 1 (offset 1341 lines).

Deleting these files also don't work for the same reason, even when
using the hex representation, i.e. (delete-file "\u00c4foo.go"), or with
DELETE-FILE-RECURSIVELY.

One workaround is to avoid the use of BOOTSTRAP-ORIGIN by applying the
patches and snippet in phases, but that's suboptimal because it has to
be done for all of GCC-BOOT0, LIBSTDC++, and GCC-FINAL.

I'll try this workaround to get things going, but hoping for better
suggestions!
