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

7.5.1 failed to build. Looks like the same error as before. I'll try Steven's linked suggestion with 7.6, and see if that flies. Thanks for all your help, by the way! One suggestion: if the OPENBLAS_CONFIGURE="TARGET=ATOM" make command builds everything correctly, then maybe the next version

It is curious that 7.5.1 would build but not 7.6. You might get some mileage with OPENBLAS_CONFIGURE="TARGET=ATOM" make See this thread: https://groups.google.com/forum/#!topic/sage-release/3QJoAgg9bgo On Monday, April 10, 2017 at 8:00:51 PM UTC-5, Ackbach wrote: > > I'm afraid I don't have

OK 7.5.1 and 7.6 have the same version of openblas, so something else changed to cause the build failure. So, yes try to build 7.5.1 again. If it fails now, the cause is likely a change in the host system. If it succeeds that’s probably something else in sage that changed. > On 11/04/2017, at

I'm afraid I don't have that data. I will say I've never been able to compile Sage 7.6 the first time. I have definitely been able to compile 7.5.1 and earlier the first time, though sometimes there are still errors. I can try to compile 7.5.1 on this machine and get back to you how it works.

Did it start happening with openblas 0.2.19 or did it suddenly happen one release build openblas 0.2.19 successfully and the next didn’t? I suspect it is a CPU detection problem, we have seen similar logs before on atom chips. François > On 11/04/2017, at 07:45, Ackbach
