Re: [sage-devel] Re: Can't compile 8.4.beta3
Dear John and Erik, Thanks for the hints. I have tried recompiling several times as suggested but the build still fails, sometimes on pip-18.0 and sometimes on python3-3.6.6.p0. Given the potential race condition in https://trac.sagemath.org/ticket/18438 I'll try compiling with a single core and see if this works.

[sage-devel] QQ not isomorphic to itself?!
sage: Qx = PolynomialRing(QQ,'x') sage: F1 = NumberField(Qx([0,1]),'a1'); F1 Number Field in a1 with defining polynomial x sage: F2 = NumberField(Qx([0,1]),'a2'); F2 Number Field in a2 with defining polynomial x sage: F1.is_isomorphic(F2) False The bug is because of this: sage: f1=F1.pari_polynomial(); f1 x sage: f2=F2.pari_polynomial(); f2 x sage: f1.nfisisom(f2) [0] sage: f1.nfisisom(f2) ==0 True So pari correctly finds an isomorphism but Sage thinks that paris's [0] is the same as pari's 0, the latter being what is returned when the fields are not isomorphic.

If nothing else, I am making it easier to maintain now, so if someone wants to hack on it it will be easier to do so now and has an "official" home: https://gitlab.com/sagemath/zn_poly/ Though I'm not 100% sure about putting it at the top-level of the sagemath/ org.

NTL is your best best. However zn_poly is a tour de force. It would be hard to beat.
