All right! Sage 7.6 compiled correctly, so far as I know. I haven't run the tests, but it opens into a notebook in Firefox, and correctly computes
integrate(e^(-x^2),x,-infinity,infinity) Is there a way to combine the OPENBLAS_CONFIGURE command with the -j4 option for using multiple cores to compile? It did take a VERY long time to compile - I think it was about 8 hours. In any case, targeting an ATOM processor seems like a common-enough occurrence that it deserves a mention in the manual, if it's not there already (I haven't looked, and please don't shoot me). Thanks much! Cheers. On Tuesday, April 11, 2017 at 6:50:10 AM UTC-4, Ackbach wrote: > > 7.5.1 failed to build. Looks like the same error as before.
