Argh, pressed sent by accident. Now again: Hi [sage-devel], (CC [linbox-devel] FYI)
Brice (for [sage-devel]: he's from the LinBox project) and I are at the "Efficient Linear Algebra for Gröbner Basis Computations" workshop at the moment and got kind of sidetracked into updating LinBox in Sage. Sage still uses version 1.1.6 which was released 4 years ago, this is embarrassing! Anyway, we got it to compile and Sage starts! See http://trac.sagemath.org/sage_trac/ticket/12883 which has a bunch of dependencies: * Givaro update: http://trac.sagemath.org/sage_trac/ticket/9511 * M4RIE update (because of Givaro update): http://trac.sagemath.org/sage_trac/ticket/12840 * M4RI update (because of the Givaro update): http://trac.sagemath.org/sage_trac/ticket/12841 However, we found two bugs already. One of them is definitely in upstream (reduced row echelon forms are wrong when using EchelonDomain's but work when one is using FFPACK directly). I believe Brice will report this bug to LinBox properly. Another but which is a segfault in determinants over the Integers. However, we cannot reproduce this outside of Sage, so this bug needs some tracking down. It is plausible that there are more bugs. Hence, I'd appreciate help. That is, please try to compile this code and try to track down issues and perhaps fix them. It seems we are closer to upgrading LinBox than we were before and I would hate to see this bitrot. For that to happen, we need your help.
