Hi,
The public notebook servers on sage.math.washington.edu are jailed
(http://sagemath.org/doc/html/inst/node10.html). Also there is a pool
of 30 unix users that are used to evaluate worksheet code. That
protects the main notebook system from a random user. Ulimit is also
used.

Sage-2.8.5 compiled fine on SUSE, so this problem only occurs with a
very recent version of gen.pyx. I recently modified the factor
function in gen.pyx so that it would do provably-correct factorization
of integers. Since that's the function causing the compiler error,
probably something I did cau

This is because [...] creates a python list, which
Last update was over 7 years ago; 6 months after the creation date. I think
it's safe to assume that this is a dead project.

Definitely, but it is something completely different. It also seems

Hi Robert,
I can't seem to get primessq to be defined as a cdef long*. I've
tried
cdef long primessq[46] = [...]
cdef long *primessq = [...]
etc. and they always give errors. Cython doesn't allow you to use
macros (#define) I guess?

As far as I can tell Suse 9.1 AMD64 ships with gcc 3.3, which is not
C99 conform. So flint won't build, you need at least gcc 3.4 or

This version does not upgrade or install on suse 9.1 amd64.
I would not make it a priority since these machines are due to be upgraded,
but thought I'd let you know.
However, it does not install on suse 10.2 either!
In case this helps:
