Hi Jerome,<br>
<br>
Thank you for your reply! I checked the openblas, it's installed correctly, and I also put the proper path into the make.inc file. I still receive some arm64 related issues:<br>
<br>
<br>
Undefined symbols for architecture arm64:<br>
<br>
"_mpi_abort_", referenced from:<br>
<br>
___w90_io_MOD_io_error in io.o<br>
<br>
"_mpi_comm_rank_", referenced from:<br>
<br>
___w90_io_MOD_io_error in io.o<br>
<br>
"_mpi_comm_size_", referenced from:<br>
<br>
___w90_io_MOD_io_error in io.o<br>
<br>
ld: symbol(s) not found for architecture arm64<br>
<br>
Those are the only errors so far. Any ideas what those could be?<br>
<br>
Best,<br>
Max<br>

Dear Max,<br>
<br>
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?<br>
<br>
Yours,<br>
Jerome.<br>

Subject: [Wannier] Compiling wannier90 on macosx with arm64 architecture<br>
<br>
Hi!<br>
<br>
I'm trying to compile wannier on my MacBook Air with arm64 processor and receive a lot of errors like, for example, this<br>
<br>
<br>
ld: can't map file, errno=22 file '/opt/homebrew/opt/openblas/lib' for architecture arm64<br>
<br>
<br>
Undefined symbols for architecture arm64:<br>
<br>
"_dcopy_", referenced from:<br>
<br>
___w90_comms_MOD_comms_scatterv_real_3 in comms.o<br>
<br>
<br>
I'm wondering if someone tried to compile wannier on a similar machine and experienced similar problems? Is there a way out?<br>
<br>
<br>
Thank you!<br>
<br>
<br>
Best regards,<br>
<br>
