Subject Re: Make scalapkg fails if USE_BLAS is set to openblas/mkl/apple
Date Wed, 06 Jun 2018 13:47:54 GMT
Yes, we have checked that as well, but did not help in our case. I've
checked out a commit close to 1.1 where it was still working and built it
with the new ci scripts (using cmake build for armv7) and it failed very
similar. It seems that the problem might be in the way we are building the
library.

Are you using cmake or make for builds?
