RQDF has nothing to do with mpfr. It's the quaddouble*.spkg which is 100% independent of GMP/MPFR. That said, if you build quaddouble directly and run its test suite, what happens. Regarding the flint problem, that was caused by a problem with how the spkg was configured -- it should have turned off funroll_loops but it didn't correctly do so (it used to). -- William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~----------~----~----~----~------~----~------~--~---
