If you type x = polygen(GF(7)) before defining mpoly, then mpoly.factor() will factor it mod 7. Probably better though is to type x = polygen(ZZ) before defining mpoly, so that mpoly knows that it is an integer polynomial: sage: mpoly.parent() Univariate Polynomial Ring in x over Integer Ring

Was there there something from the original Sage install (compiled from source) that produced the different CXXFLAGS? Strange that only the Sage config.log had "#define _4ti2_HAVE_MPZ_INT64_CONVERSION 1". On Sunday, January 12, 2014 5:15:34 PM UTC-5, rickhg12hs wrote: > > FYI, building 4ti2 ind
