[sage-devel] Build on OpenSuSE 12.1 w/ 3.1 kernel

2012-02-03 Thread deSitter
Very straightforward, with one bump - the supplied Parma Polyhedron Library libppl.so.9.0.0 confused the linker, so a single unresolved symbol was found. The compilation failed. At that point, I pointed the symbolic links in sagedir/local/lib to the version of libppl that comes with the SuSE distru

Hello, It is a known bug? Or maybe not considered a bug at all? Quick search does not show anything related... sage: f(x) = x sage: f x |--> x sage: integral(f, x) x |--> 1/2*x^2 sage: integral(f, x, 0, 1) x |--> 1/2 The last line shows 1/2 as a function of x, but it is not a function anymore, i

[sage-devel] sage cluster downtime

I have reconfigured the storage server in the sage cluster, and will be re-enabling it at 12 midnight PST on Feb 10/11 (this should be right in between the all the sage days going on). This should hopefully resolve some of the io issues that we have been experiencing since last July. The downtime w

Hi, interesting. I have the faint hope that the fix at http://trac.sagemath.org/sage_trac/ticket/12161 (which I hope to review this weekend --- it requires building twice a Sage app on OS X 10.6, and then test these on OS X 10.7) will also cure this. Even though this new report is on OS X 10.6!
