Error installing package singular-4.4.0

[John Cremona]

I am building 10.7.beta2 in order to review a PR, on Ubuntu 24.04.2 LTS.

After
git pull upstream develop
make distclean
./bootstrap
./configure
make

it fails on installing package singular-4.4.0. Log files attached.
The problem is with FLINT. config.log finds an apparently suitable
FLINT version installed:

real_configure:25233: g++ -std=gnu++11 -o conftest -Dlinux

My flint version is flint-3.2.0.rc1 (in /usr/local/lib I have
libflint.so.20.0.0 and in /usr/local/include/flint/flint.h I see
#define FLINT_VERSION "3.2.0-rc1").

Obviously I will upgrade to FLINT-3.3.0, but the configure script
should not have accepted my FLINT, surely?

Hi John,

Flint is already on 3.2.2, see https://github.com/flintlib/flint

If could be that your Flint beta is buggy, and you need 3.2.2

We should upgrade to it, if possible.

Singular is now 4.4.1 - not 100% sure whether an upgrade is feasible.

I know that flint 3.1.3 is working with Singular 4.4.0 (and, apparently, 3.2,* is not)

There is also a request to update gfan, to version 0.7.

IIRC gfan-0.7 uses glibc int128 types everywhere without testing for
them, so it will fail on Gentoo, Void, Alpine, etc. where the libc may
not be glibc. I emailed Anders about it a while ago.

This is now https://github.com/sagemath/sage/pull/40033 (not really tested yet, but should be OK - as it's already in Conda and Homebrew)

OK, I made a comment there and will look at it tomorrow.
