I updated or created the different spkgs (which was kind of trivial) and put them on the following webpage: http://www.infres.enst.fr/~flori/ecc2011 or: http://perso.telecom-paristech.fr/~flori/ecc2011 if the other one is down. IT needs a recent version of MPIR as found for example in trac #8664 merged in the next 4.7.2.alpha3. My main interest is to get access to the functions in CM, so I'm currently working on it and a very early patch (I think I'll locate the files elsewhere and change the class name and add doc and add doctests ...) is available on the above page. Computing the different class polynomials is working, but I get an assert failure in MPIR when trying to compute a cryptographic curve through Sage that I don't get calling directly the example binaries built with the library which seem to point to exactly the same libraries. Maybe did I something wrong while building it. I'll open tickets for all of this today.
I did not take care of MPFI because it seems that Burcin built a new spkg here: http://groups.google.com/group/sage-devel/browse_thread/thread/8cca88a5482a830f On 3 sep, 21:56, leif <not.rea...@online.de> wrote: > On 1 Sep., 11:02, Jean-Pierre Flori <jpfl...@gmail.com> wrote: > > > Dear all, > > > During the coding sprints taking place at ECC2011 summer school, one > > of our project might be to build interfaces to the three libraries > > available at multiprecision.org (by Andreas Enge and others): > > - MPC (complex numbers with arbitrary precision - an optional spkg > > already exists, so that would only be an update - see trac #4446) > > - MPFRCX (polynomials using the above lib and MPFR) > > - CM (construction of class polynomials by floating-point > > approximation using the above libs) > > > I'd like to know if anyone has any suggestion or objection about/ > > against that idea. > > (A list of other potential topics can be found > > athttp://www.loria.fr/~zimmerma/ecc.html) > > While you're at it (TM), you may also consider upgrading Sage's MPFI. > > This has been on the "high-priority wishlist" of SD32, but AFAIK > there's not even a ticket for this yet. > > The "current" version in Sage is MPFI 1.3.4-cvs20071125 (p8), while > the latest upstream version is 1.5.0, released August 12th 2010 [1]. > > -leif > > [1]https://gforge.inria.fr/projects/mpfi/ -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
