Request: Singular 4.2.1p2, FLINT 2.8.4, Arb 2.21.1, pdf2svg 0.2.3

[Samuel Lelièvre]

Dear Cygwin package maintainers,

This is to kindly request upgrading two existing
packages for mathematical software (Singular and
FLINT), and creating packages for two other pieces
of software, one mathematical library for arbitrary
precision real and complex floating point
calculations based on ball arithmetic (Arb),
and one graphics utility for converting between
graphical file formats, from pdf to svg (pdf2svg).

My wishlist as a list with extra links:

- upgrade "singular" package to Singular 4.2.1p2

  https://www.singular.uni-kl.de/
  https://github.com/Singular/Singular
  https://github.com/Singular/Singular/tags
  https://repology.org/project/singular/versions

- upgrade "flint" package to FLINT 2.8.4

  http://flintlib.org/
  https://github.com/wbhart/flint2
  https://github.com/wbhart/flint2/tags
  https://repology.org/project/flint/versions

- package Arb 2.21.1

  https://arblib.org/
  https://github.com/fredrik-johansson/arb
  https://github.com/fredrik-johansson/arb/tags
  https://repology.org/project/arb-fp/versions

- package pdf2svg 0.2.3

  http://cityinthesky.co.uk/opensource/pdf2svg/
  https://github.com/dawbarton/pdf2svg
  https://github.com/dawbarton/pdf2svg/releases
  https://github.com/dawbarton/pdf2svg/tags
  https://repology.org/project/pdf2svg/versions

Or if someone can teach me how to do that,
I would be happy to learn in order to be able
to contribute in the future. In particular there
are a number of other pieces of mathematical
software I would like to help package.

Thanks for all the packaging effort.   --Samuel

Flint build for 64bit on the way.
It seems there is an API bump from 15 to 16

These are new, so you can propose it

start reading from:
https://cygwin.com/packaging-contributors-guide.html

and we can follow up on cywin-apps mailing list

https://cygwin.com/mailman/listinfo/cygwin-apps

This is very appreciated. I can help you on that.

I never used Singular so my interest to update it was always
very limited;
last time it was mean Yue Ren to take care and I to just help him

https://sourceware.org/pipermail/cygwin-announce/2015-May/006150.html

but he never followed up on following releases.

About Singular last package build, the main issue in my opinion
is that the dynamic loading of "module" was transformed by Yue in a
static implementation.
I was trying to enable the dynamic loading but he preferred to
go for the current solution.
So I suspect the old patches could need an adjustment for the latest 
4.2.1p2 source code.

If you are really interested on taking over Singular maintainership
we can follow up by private mail.

Marco

The pdf2svg home page recommends instead pdftocairo from the poppler 
package, which does the same and is maintained as part of the package, 
rather than being a standalone utility which integrates the two, and is 
not as well maintained:
