[sage-devel] Unable to build GAP3

2017-10-26 Thread Travis Scrimshaw
I know its an experimental package, but it is something that some of us would like to see made into an optional spkg someday. I've been trying to install it on a Sage install on a small cluster, but because its GCC 4, it is using the GCC included with Sage. I think that is the difference with my

I don't entirely agree with Vincent's fix as it hides the symptom of the underlying problem: the quotient is not in finite fields: sage: R. = PolynomialRing(GF(3)) sage: f = x^2 + x + 2 sage: K. = f.root_field() sage: K.category() Category of commutative no zero divisors quotients of algebras ove

Dear Barbara, Thanks for your detailed report! In this case, if it just boils down to have a .list() method, it should be straightforward to implement. Would you be interested in working on this? The procedure to make modification to Sage source code is described in the developer guide

Dear Sage-Developers, I came across the following issue / feature request when working with the coding theory classes: Getting a syndrome table of a code over GF(9) works, but using a 'hand-crafted version' of GF(9) will not work, although(?) the available decoders include 'Syndrome'. See the S

Hi, I don't see how https helps with any such attack. What I always pointed out is to use checksums. e.g. the webseed torrent files here http://files.sagemath.org/torrents.html have checksums and what would be missing is to sign them. AFAIK there is no official public/private key for files on s

There are various downloads that we need to consider: (A) Downloads of Sage-the-distribution source/binary tarballs (B) Cloning the git repo (C) Downloading tarballs while building from the git repo I think that (A) should be our primary worry, since those are usually not checked by anybody. Fo
