Changes in FLINT 2.7.0 (from NEWS file)

2.7.0 -- 11 Dec 2020

Multivariate factorisation
Square root and square testing for finite fields
Square root and square testing for multivariates
Zassenhaus factoring speedups (incl. degree pruning)
Fast factorisation of cubic univariate polynomials
Add context objects to fmpz_mod_poly functions
Use BLAS for matrix multiplication over Z/nZ (small n)
Linear solving for non-square/singular matrices (can_solve)
Speed up factorisation over Z/nZ (for multiprecision n)

From the packaging point of view the main changes will be

configuring BLAS
pthread support
context object in fmpz_mod_poly function (API change)

Flint 2.7-rc2 is out. Can someone test with Sage?

Flint 2.7.0 was released today (2020-12-18).

singular and e-antic fail to build due to the API changes in fmpz_mod_poly

Actually, Singular is fixed in the (just released) 4.2.0 version. Unfortunately doesn't help much since the Singular upgrade has been stuck for years in #25993

sagelib itself builds fine with flint 2.7 and passes doctests, modulo the singular upgrade.

comment:10

For the record, we are now up to Flint 2.7.1. As the timing and numbering suggest, this is mainly a bugfix release.

e-antic has been fixed (in head, to be 1.0.0).

It builds because it's not using flint

checking for FLINT >= 2.4... problem
Sorry, your FLINT version is too old. Disabling.

After merging this ticket into #31548 (since I want to use new functionality from FLINT 2.7.1 there) I'm getting errors starting Sage. I don't usually update spkgs outside of beta releases, so I could be doing something wrong (I'm running OS X 10.15.2).

$ git trac fetch 31069 && git merge

I believe you need singular 4.2.0p1 (9.3.beta8 if I am not mistaken) with that. Singular uses flint so does need rebuilding and 4.2.0 is the first one that is compatible with flint-2.7.1.

roed314 · 2021-03-30T08:53:12Z

comment:51

Despite the folder name, this is based on sage-9.3.beta9, and when I did make build it appeared to be building singular-4.2.0p1+2021-03-13+sage.

I feel like I'm missing something basic here: when I try running sage -f flint it gives me lots of errors saying that flint-2.7.1 isn't found:

OK, then it appears that somehow sage/matrix/matrix_mpolynomial_dense.cpython-39-darwin.so has not be rebuilt because it is still looking for libSingular-4.1.1 when it should look for libSingular-4.2.0.

This ticket is not merged, tarball are not usually mirrored before Volker attempt to merge the tickets. You'll have to fetch the source a different way. Matthias created a handy way of using a string called upstream_url in the file checksum.ini to do the fetching from upstream but I cannot remember how it works.

Do this:

$ ./bootstrap -q
$ ./configure --enable-download-from-upstream-url -q
$ make -s V=0

Thanks! That seems to have worked.

comment:57

For anyone else looking at this, I also had to do sage -f flint after the commands Samuel gave.

slel · 2021-03-31T18:30:03Z

comment:58

This should do everything at once:

$ ./bootstrap -q
$ ./configure --enable-download-from-upstream-url -q
$ make -s V=0 flint-clean
$ make -s V=0
