Pkg xen devel - Jan 2024 - Bug#1062048: xen: FTBFS with Python 3.12 as default

Source: xen
Version: 4.17.2+76-ge1f9cb16e2-1
Severity: serious
Tags: ftbfs patch
User: debian-python at lists.debian.org
Usertags: python3.12

Hi Maintainer

xen FTBFS with Python 3.12 as the default version (i.e. with
python3-defaults/3.12.1-1 from experimental).  I've copied what I hope
is the relevant part of the log below.

I was able to work around this by:

-PY_CFLAGS = $(CFLAGS) $(PY_NOOPT_CFLAGS)
+PY_CFLAGS = $(CFLAGS) $(PY_NOOPT_CFLAGS) -Wno-error=declaration-after-statement

in tools/python/Makefile and tools/pygrub/Makefile.

Regards
Graham
