Comment(by spancratz):
Hi Martin,
I've now implemented all methods in the prototype. (I'll attach a new
patch in a few minutes.) All of your above comments make sense and I can
go through this tomorrow. One thing I could not get done is make SAGE use
this implementation by default. In the file polynomial_ring.py, I tried
replacing the line 1185 with
from sage.rings.polynomial.polynomial_rational_flint import
Polynomial_rational_dense_flint
element_class = Polynomial_rational_dense_flint
and while building still works, executing ./sage results in a whole screen
full output, ending with
b37bb0/home/suser/sage-4.1.2.alpha0/local/bin/sage-sage: line 199:
16297 Aborted sage-ipython "$@" -i
Am I making a mistake in the way I am trying to switch the default, or
does this due to problems in the actual new implementation? I've got no
idea how to fix this. Of course, I am then happy to do lots of testing.
Kind regards,
Sebastian
