[Wannier] Compiling wannier90 on macosx with arm64 architecture

[Jerome Jackson - STFC UKRI]

Dear Max,

it appears that you don't have (or are not linking to) a working blas library (dcopy is part of blas) for arm64 machine...  Are you sure that homebrew is installing openblas correctly?  Does brew install openblas correctly, or does it complain somehow?

Yours,
Jerome.

Hi!

I'm trying to compile wannier on my MacBook Air with arm64 processor and receive a lot of errors like, for example, this


ld: can't map file, errno=22 file '/opt/homebrew/opt/openblas/lib' for architecture arm64


Undefined symbols for architecture arm64:

  "_dcopy_", referenced from:

      ___w90_comms_MOD_comms_scatterv_real_3 in comms.o


I'm wondering if someone tried to compile wannier on a similar machine and experienced similar problems? Is there a way out?


Thank you!


Best regards,

Max.
