Build fails on Mac M1 / Ventura 13.3.1

[petercip]

My apologies for posting this. My knowledge of build flags is extremely out-of-date. I assume there are some environment variables missing when I run gem install numo-linalg. Any help is much appreciated.

I did try prefixing the command with MACOSX_DEPLOYMENT_TARGET=13.0 and MACOSX_DEPLOYMENT_TARGET=12.0

Warnings

During build there are 121 warnings nearly all like below. I'm not sure those matter:

warning: implicit conversion loses integer precision: 'size_t' (aka 'unsigned long') to 'blasint' (aka 'int') [-Wshorten-64-to-32]

Resolved this by installing openblas with homebrew, then:

gem install numo-linalg -- --with-ldflags="-Wl,-undefined,dynamic_lookup" --with-openblas-dir=/opt/homebrew/opt/openblas
